WARNING!

• ONLY an authorized service technician should con-

nect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.

• If unauthorized equipment is connected to the

OBD II connection port, such as a driver-behavior
tracking device, it may:

• Be possible that vehicle systems, including safety

related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.

• Access, or allow others to access, information

stored in your vehicle systems, including personal
information.

For further information, refer to “Cybersecurity” in “Mul-
timedia”.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS

In some localities, it may be a legal requirement to pass an
inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.

For states that require an Inspection and Main-
tenance (I/M), this check verifies the “Malfunc-
tion Indicator Light (MIL)” is functioning and is
not on when the engine is running, and that the

OBD II system is ready for testing.

Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.

Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system is ready, you must do the following:

1. Cycle the ignition switch to the ON position, but do not

crank or start the engine.

NOTE:

If you crank or start the engine, you will have to

start this test over.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

2. As soon as you cycle the ignition switch to the ON

position, you will see the “Malfunction Indicator Light
(MIL)” symbol come on as part of a normal bulb check.

3. Approximately 15 seconds later, one of two things will

happen:

• The MIL will flash for about ten seconds and then return

to being fully illuminated until you turn OFF the igni-
tion or start the engine. This means that your vehicle’s
OBD II system is not ready and you should not proceed
to the I/M station.

• The MIL will not flash at all and will remain fully

illuminated until you place the ignition in the off posi-
tion or start the engine. This means that your vehicle’s
OBD II system is ready and you can proceed to the I/M
station.

If your OBD II system is not ready, you should see an
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your vehicle
as you normally would in order for your OBD II system to
update. A recheck with the above test routine may then
indicate that the system is now ready.

Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.

SAFETY FEATURES

Anti-Lock Brake System (ABS)

The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most brak-
ing conditions. The system automatically prevents wheel
lock, and enhances vehicle control during braking.

The ABS performs a self-check cycle to ensure that the ABS
is working properly each time the vehicle is started and
driven. During this self-check, you may hear a slight
clicking sound as well as some related motor noises.

ABS is activated during braking when the system detects
one or more wheels begin to lock. Road conditions such as
ice, snow, gravel, bumps, railroad tracks, loose debris, or
panic stops may increase the likelihood of ABS activa-
tion(s).

You also may experience the following when ABS activates:
• The ABS motor noise (it may continue to run for a short

time after the stop).

• The clicking sound of solenoid valves.
• Brake pedal pulsations.
• A slight drop of the brake pedal at the end of the stop.

These are all normal characteristics of ABS.

WARNING!

• The ABS contains sophisticated electronic equip-

ment that may be susceptible to interference caused
by improperly installed or high output radio trans-
mitting equipment. This interference can cause pos-
sible loss of anti-lock braking capability. Installation
of such equipment should be performed by qualified
professionals.

• Pumping of the Anti-Lock Brakes will diminish their

effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.

• The ABS cannot prevent the natural laws of physics

from acting on the vehicle, nor can it increase brak-
ing or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded.

• The ABS cannot prevent collisions, including those

resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.

SAFETY

-------------------------------------------------------------------------------------------------------------------------------------------------------------

WARNING! (Continued)

• The capabilities of an ABS equipped vehicle must

never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.

ABS is designed to function with the OEM tires. Modifica-
tion may result in degraded ABS performance.

Anti-Lock Brake Warning Light

The yellow “Anti-Lock Brake Warning Light” will turn on
when the ignition is turned to the ON/RUN mode and
may stay on for as long as four seconds.

If the “Anti-Lock Brake Warning Light” remains on or
comes on while driving, it indicates that the anti-lock
portion of the brake system is not functioning and that
service is required. However, the conventional brake sys-
tem will continue to operate normally if the “Anti-Lock
Brake Warning Light” is on.

If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore the

benefits of anti-lock brakes. If the “Anti-Lock Brake Warn-
ing Light” does not come on when the ignition is turned to
the ON/RUN mode, have the light repaired as soon as
possible.

Electronic Brake Control System

Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Electronic Stability
Control (ESC), and Electronic Roll Mitigation (ERM). These
systems work together to enhance both vehicle stability
and control in various driving conditions.

Your vehicle may also be equipped with Ready Alert
Braking (RAB), Rain Brake Support (RBS), Trailer Sway
Control (TSC), and Dynamic Steering Torque (DST).

Traction Control System (TCS)

This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce vehicle power to provide enhanced acceleration
and stability. A feature of the TCS, Brake Limited Differen-
tial (BLD), functions similar to a limited slip differential

SAFETY

221

-------------------------------------------------------------------------------------------------------------------------------------------------------------

and controls the wheel spin across a driven axle. If one
wheel on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more vehicle torque to be applied to the wheel
that is not spinning. BLD may remain enabled even if TCS
and ESC are in a reduced mode.

Brake Assist System (BAS)

The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The sys-
tem detects an emergency braking situation by sensing the
rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the anti-lock
brake system (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit of
the system, you must apply continuous braking pressure
during the stopping sequence, (do not “pump” the brakes).
Do not reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released, the BAS is
deactivated.

WARNING!

The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The capa-
bilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user’s safety or the safety of
others.

Brake System Warning Light

The red “Brake System Warning Light” will turn on when
the ignition is turned to the ON/RUN mode and may stay
on for as long as four seconds.

If the “Brake System Warning Light” remains on or comes
on while driving, it indicates that the brake system is not
functioning properly and that immediate service is re-
quired. If the “Brake System Warning Light” does not come
on when the ignition is turned to the ON/RUN mode, have
the light repaired as soon as possible.

222

SAFETY

-------------------------------------------------------------------------------------------------------------------------------------------------------------

Dynamic Steering Torque (DST)

Dynamic Steering Torque is a feature of the ESC and
Electric Power Steering (EPS) modules that provides
torque at the steering wheel for certain driving conditions
in which the ESC module is detecting vehicle instability.
The torque that the steering wheel receives is only meant to
help the driver realize optimal steering behavior in order to
reach/maintain vehicle stability. The only notification the
driver receives that the feature is active is the torque
applied to the steering wheel.

NOTE:

The DST feature is only meant to help the driver

realize the correct course of action through small torques
on the steering wheel, which means the effectiveness of the
DST feature is highly dependent on the driver’s sensitivity
and overall reaction to the applied torque. It is very
important to realize that this feature will not steer the
vehicle, meaning the driver is still responsible for steering
the vehicle.

Electronic Brake Force Distribution (EBD)

This function manages the distribution of the braking
torque between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip of
the rear wheels to avoid vehicle instability, and to prevent
the rear axle from entering ABS before the front axle.

Electronic Roll Mitigation (ERM)

This system anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and the speed
of the vehicle. When ERM determines that the rate of
change of the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.

WARNING!

Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that
wheel lift or rollover may occur. ERM cannot prevent
all wheel lift or roll overs, especially those that involve
leaving the roadway or striking objects or other ve-
hicles. The capabilities of an ERM-equipped vehicle
must never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or the
safety of others.

SAFETY

223

-------------------------------------------------------------------------------------------------------------------------------------------------------------

Electronic Stability Control (ESC)

This system enhances directional control and stability of
the vehicle under various driving conditions. ESC corrects
for oversteering or understeering of the vehicle by apply-
ing the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.

ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or understeer
condition.
• Oversteer — when the vehicle is turning more than

appropriate for the steering wheel position.

• Understeer — when the vehicle is turning less than

appropriate for the steering wheel position.

The “ESC Activation/Malfunction Indicator Light” located
in the instrument cluster will start to flash as soon as the
ESC system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the TCS is
active. If the “ESC Activation/Malfunction Indicator

Light” begins to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible. Be sure to
adapt your speed and driving to the prevailing road
conditions.

WARNING!

• Electronic Stability Control (ESC) cannot prevent the

natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capa-
bilities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.

• Vehicle modifications, or failure to properly main-

tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect

SAFETY

-------------------------------------------------------------------------------------------------------------------------------------------------------------

WARNING! (Continued)

the performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly
worn tires may also degrade ESC performance. Any
vehicle modification or poor vehicle maintenance
that reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.

ESC Operating Modes

NOTE:

Depending upon model and mode of operation, the

ESC system may have multiple operating modes.

ESC On

This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.

Partial Off

The “Partial Off” mode is intended for times when a more
spirited driving experience is desired. This mode may
modify TCS and ESC thresholds for activation, which
allows for more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes stuck.

To enter the “Partial Off” mode, momentarily push the
“ESC Off” button and the “ESC Off Indicator Light” will
illuminate. To turn the ESC on again, momentarily push
the “ESC Off” button and the “ESC Off Indicator Light”
will turn off.

NOTE:

When driving with snow chains, or when starting

off in deep snow, sand, or gravel, it may be desirable to
allow more wheel spin. This can be accomplished by
momentarily pushing the “ESC Off” button to enter partial
mode “Partial Off” mode. Once the situation requiring
“Partial Off” mode is overcome, turn ESC back on by
momentarily pushing the “ESC Off” button. This may be
done while the vehicle is in motion.

SAFETY

225

-------------------------------------------------------------------------------------------------------------------------------------------------------------

WARNING!

• When in “Partial Off” mode, the TCS functionality

of ESC, (except for the limited slip feature described
in the TCS section), has been disabled and the “ESC
Off Indicator Light” will be illuminated. When in
“Partial Off” mode, the engine power reduction
feature of TCS is disabled, and the enhanced vehicle
stability offered by the ESC system is reduced.

• Trailer Sway control (TSC) is disabled when the ESC

system is in the “Partial Off” mode.

ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light

The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition is turned to the ON mode. It
should go out with the engine running. If the

“ESC Activation/Malfunction Indicator Light” comes on
continuously with the engine running, a malfunction has
been detected in the ESC system. If this light remains on

after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as soon as
possible to have the problem diagnosed and corrected.

The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as the
tires lose traction and the ESC system becomes active. The
“ESC Activation/Malfunction Indicator Light” also flashes
when TCS is active. If the “ESC Activation/Malfunction
Indicator Light” begins to flash during acceleration, ease
up on the accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the prevailing
road conditions.

NOTE:
• The “ESC Activation/Malfunction Indicator Light” and

the “ESC OFF Indicator Light” come on momentarily
each time the ignition is turned ON.

• Each time the ignition is turned ON, the ESC system will

be on even if it was turned off previously.

226

SAFETY

-------------------------------------------------------------------------------------------------------------------------------------------------------------

• The ESC system will make buzzing or clicking sounds

when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.

The “ESC OFF Indicator Light” indicates the
customer has elected to have the Electronic Sta-
bility Control (ESC) in a reduced mode.

Hill Start Assist (HSA)

The HSA system is designed to mitigate roll back from a
complete stop while on an incline. If the driver releases the
brake while stopped on an incline, HSA will continue to
hold the brake pressure for a short period. If the driver
does not apply the throttle before this time expires, the
system will release brake pressure and the vehicle will roll
down the hill as normal.

The following conditions must be met in order for HSA to
activate:
• The feature must be enabled.
• The vehicle must be stopped.
• Park brake must be off.
• Driver door must be closed.

• The vehicle must be on a sufficient grade.
• The gear selection must match vehicle uphill direction

(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).

• HSA will work in REVERSE gear and all forward gears.

The system will not activate if the transmission is in
PARK or NEUTRAL. For vehicles equipped with a
instruction transmission, if the clutch is pressed, HSA will
remain active.

WARNING!

There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
such as on minor hills or with a loaded vehicle, or
while pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the driver’s
responsibility to be attentive to distance to other ve-
hicles, people, and objects, and most importantly brake
operation to ensure safe operation of the vehicle under
all road conditions. Your complete attention is always
required while driving to maintain safe control of your
vehicle. Failure to follow these warnings can result in
a collision or serious personal injury.

SAFETY

227

-------------------------------------------------------------------------------------------------------------------------------------------------------------

Towing With HSA

HSA will also provide assistance to mitigate roll back while
towing a trailer.

WARNING!

• If you use a trailer brake controller with your trailer,

the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resum-
ing acceleration, instructionly activate the trailer brake
or apply more vehicle brake pressure prior to releas-
ing the brake pedal.

• HSA is not a parking brake. Always apply the

parking brake fully when exiting your vehicle. Also,
be certain to place the transmission in PARK.

• Failure to follow these warnings can result in a

collision or serious personal injury.

Disabling And Enabling HSA

This feature can be turned on or turned off. To change the
current setting, proceed as follows:
• If disabling HSA using Uconnect Settings, refer to

“Uconnect Settings” in “Multimedia” for further infor-
mation.

Rain Brake Support (RBS)

Rain Brake Support may improve braking performance in
wet conditions. It will periodically apply a small amount of
brake pressure to remove any water buildup on the front
brake rotors. It functions when the windshield wipers are
in LO or HI speed. When Rain Brake Support is active,
there is no notification to the driver and no driver interac-
tion is required.

Ready Alert Braking (RAB)

Ready Alert Braking may reduce the time required to reach
full braking during emergency braking situations. It antici-
pates when an emergency braking situation may occur by
monitoring how fast the throttle is released by the driver.
The EBC will prepare the brake system for a panic stop.

228

SAFETY

-------------------------------------------------------------------------------------------------------------------------------------------------------------

Trailer Sway Control (TSC)

TSC uses sensors in the vehicle to recognize an excessively
swaying trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become active automati-
cally once an excessively swaying trailer is recognized.
Note that TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and follow the
trailer tongue weight recommendations. Refer to “Trailer
Towing” in “Starting And Operating” for further informa-
tion. When TSC is functioning, the “ESC Activation/
Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being applied
to individual wheels to attempt to stop the trailer from
swaying. TSC is disabled when the ESC system is in the
“Partial Off” mode.

WARNING!

If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

AUXILIARY DRIVING SYSTEMS

Blind Spot Monitoring (BSM) — If Equipped

The Blind Spot Monitoring (BSM) system uses two radar-
based sensors, located inside the rear bumper fascia, to
detect highway licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.

When the vehicle is started, the BSM warning light will
momentarily illuminate in both outside rear view mirrors
to let the driver know that the system is operational. The

Rear Detection Zones

SAFETY

229

-------------------------------------------------------------------------------------------------------------------------------------------------------------

BSM system sensors operate when the vehicle is in any
forward gear or REVERSE and enters stand-by mode when
the vehicle is in PARK.

The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the outside rear view mirror and extends
approximately 10 ft (3 m) beyond the rear bumper of the
vehicle. The BSM system monitors the detection zones on
both sides of the vehicle when the vehicle speed reaches
approximately 6 mph (10 km/h) or higher and will alert
the driver of vehicles in these areas.

NOTE:
• The BSM system DOES NOT alert the driver about

rapidly approaching vehicles that are outside the detec-
tion zones.

• The BSM system detection zone DOES NOT change if

your vehicle is towing a trailer. Therefore, visually verify
the adjacent lane is clear for both your vehicle and trailer
before making a lane change. If the trailer or other object
(i.e., bicycle, sports equipment) extends beyond the side
of your vehicle, this may result in false detections. The
BSM warning light may even remain illuminated the
entire time the vehicle is in a forward gear.

• The Blind Spot Monitoring (BSM) system may experi-

ence drop outs (blinking on and off) of the side mirror
Warning Indicator lamps when a motorcycle or any
small object remains at the side of the vehicle for
extended periods of time (more than a couple of sec-
onds).

The area on the rear fascia where the radar sensors are
located must remain free of snow, ice, and dirt/road
contamination so that the BSM system can function prop-
erly. Do not block the area of the rear fascia where the radar
sensors are located with foreign objects (bumper stickers,
bicycle racks, etc.).

Sensor Location

230

SAFETY

-------------------------------------------------------------------------------------------------------------------------------------------------------------

If the system detects degraded performance due to con-
tamination or foreign objects, a message will warn you of a
blocked sensor and the warning indicators in side view
mirrors will be on. The warning indicators will remain
illuminated until blockage clearing conditions are met.
First clear the fascia area around the sensors of the block-
age. After removing the blockage, the following procedure
can be used to reset the system:
• Cycle the ignition from on to off and then back on.
If the blockage message is still present after cycling the
ignition and driving in traffic, check again for a blockage.

The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM warning light
located in the outside mirrors in addition to sounding an
audible (chime) alert and reducing the radio volume. Refer
to “Modes Of Operation” in this section for further infor-
mation.

The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to see
if an alert is necessary. The BSM system will issue an alert
during these types of zone entries.
