ONBOARD DIAGNOSTIC SYSTEM — OBD II

Your vehicle is equipped with a sophisticated Onboard

Diagnostic system called OBD II. This system monitors the

performance of the emissions, engine, and transmission

control systems. When these systems are operating prop-

erly, your vehicle will provide excellent performance and

fuel economy, as well as engine emissions well within

current government regulations.
If any of these systems require service, the OBD II system

will turn on the Malfunction Indicator Light (MIL). It will

also store diagnostic codes and other information to assist

your service technician in making repairs. Although your

vehicle will usually be drivable and not need towing, see

an authorized dealer for service as soon as possible.

CAUTION!

• Prolonged driving with the MIL on could cause

further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.

• If the MIL is flashing while the vehicle is running,

severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

Onboard Diagnostic System (OBD II) Cybersecurity

Your vehicle is required to have an Onboard Diagnostic

system (OBD II) and a connection port to allow access to

information related to the performance of your emissions

controls. Authorized service technicians may need to ac-

cess this information to assist with the diagnosis and

service of your vehicle and emissions system.

WARNING!

• ONLY an authorized service technician should con-

nect equipment to the OBD II connection port in
order to 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 follow-

ing:
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.

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.

(Continued)

204

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 Trailer Sway

Control (TSC), Ready Alert Braking (RAB), Rain Brake

Support (RBS), Dynamic Steering Torque (DST), and Hill

Descent Control (HDC).

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.

SAFETY

205

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.

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.

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.

206

SAFETY

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. (If the doors are attached,

then the door must be closed. If the doors are detached

then the driver’s seatbelt must be buckled.)

• 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

manual 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.

Disabling And Enabling HSA

This feature can be turned on or turned off. To change the

current setting, refer to “Instrument Cluster Display” in

“Getting To Know Your Instrument Panel” for further

information.

Towing With HSA

HSA will also provide assistance to mitigate roll back while

towing a trailer.

SAFETY

207

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, manually 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.

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 engine power to provide enhanced acceleration and

stability. A feature of the TCS, Brake Limited Differential

(BLD), functions similar to a limited slip differential 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 engine 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.

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.

208

SAFETY

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, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC
equipped vehicle must never be exploited in a reckless
or dangerous manner which could jeopardize the us-
er’s safety or the safety of others.

(Continued)

WARNING! (Continued)

• Vehicle modifications, or failure to properly main-

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

SAFETY

209

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” switch and the “ESC Off Indicator Light” will

illuminate. To turn the ESC on again, momentarily push

the “ESC Off” switch and the “ESC Off Indicator Light”

will turn off.

NOTE:

For vehicles with multiple partial ESC modes a

momentary button push will toggle the ESC mode. Mul-

tiple momentary button pushed may be required to return

to ESC On.

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.

Full Off — If Equipped

This mode is intended for off-highway or off-road use only

and should not be used on any public roadways. In this

mode, TCS and ESC features are turned OFF. To enter the

“Full Off” mode, push and hold the “ESC Off” switch for

five seconds while the vehicle is stopped with the engine

running. After five seconds, a chime will sound, the “ESC

Off Indicator Light” will illuminate, and the “ESC OFF”

message will display in the instrument cluster. To turn ESC

ON again, momentarily push the “ESC Off” switch.

210

SAFETY

NOTE:

System may switch from ESC “Full Off” to “Partial

Off” mode when vehicle exceeds a predetermined speed.

When the vehicle speed slows below the predetermined

speed the system will return to ESC “Full Off”.
ESC modes may also be affected by drive modes if so

equipped.

WARNING!

• In the ESC “Full Off” mode, the engine torque

reduction and stability features are disabled. There-
fore, enhanced vehicle stability offered by the ESC
system is unavailable. In an emergency evasive ma-
neuver, the ESC system will not engage to assist in
maintaining stability. ESC “Full Off” mode is in-
tended for off-highway or off-road use only.

• With the ESC switched off, the enhanced vehicle

stability offered by ESC is unavailable. In an emer-
gency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. ESC “Full
Off” mode is only intended for off-highway or
off-road use.

(Continued)

WARNING! (Continued)

• The Electronic Stability Control (ESC) cannot pre-

vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent all
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions.

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.

SAFETY

211

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.

• 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.

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.

NOTE:

ERM is disabled anytime the ESC is in “Full Off”

mode (if equipped). Refer to “Electronic Stability Control

(ESC)” in this section for a complete explanation of the

available ESC modes.

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

212

SAFETY

WARNING! (Continued)

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.

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:

TSC cannot stop all trailers from swaying. Always

use caution when towing a trailer and follow the trailer

tongue weight recommendations. Refer to “Trailer Tow-

ing” in “Starting And Operating” for further information.
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” or “Full Off” modes.

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.

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.

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.
