Jeep Grand Cherokee SRT (2018 year). Manual

HAZARD WARNING FLASHERS

The Hazard Warning flasher switch is located on the switch
bank just above the climate controls.

Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn
oncoming traffic of an emergency. Push the

switch a second time to turn off the Hazard Warning
flashers.

This is an emergency warning system and it should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.

When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.

NOTE:

With extended use, the Hazard Warning flashers

may discharge the battery.

ASSIST AND SOS MIRROR — IF EQUIPPED

If equipped, the rearview mirror contains an ASSIST and a
SOS button.

IN CASE OF EMERGENCY

WARNING!

ALWAYS obey traffic laws and pay attention to the
road. ALWAYS drive safely with your hands on the
steering wheel. You have full responsibility and as-
sume all risks related to the use of the features and
applications in this vehicle. Only use the features and
applications when it is safe to do so. Failure to do so
may result in an accident involving serious injury or
death.

NOTE:
• Your vehicle may be transmitting data as authorized by

the subscriber.

• The SOS and ASSIST buttons will only function if you

are connected to an operable LTE (voice/data) or 4G
(data) network. Other Uconnect services will only be
operable if your SiriusXM Guardian service is active and
you are connected to an operable LTE (voice/data) or 4G
(data) network.

ASSIST Call

The ASSIST Button is used to automatically connect you to
any one of the following support centers:
• Roadside Assistance – If you get a flat tire, or need a tow,

just push the ASSIST button and you’ll be connected to
someone who can help. Roadside Assistance will know
what vehicle you’re driving and its location. Additional
fees may apply for roadside assistance.

• SiriusXM Guardian Customer Care – In-vehicle support

for SiriusXM Guardian.

• Vehicle Customer Care – Total support for all other

vehicle issues.

SOS Call

1. Push the SOS Call button on the Rearview Mirror.

NOTE:

will be a ten second delay before the SOS Call system
initiates a call to a SOS operator. To cancel the SOS Call
connection, push the SOS call button on the Rearview
Mirror or press the cancellation button on the Device
Screen. Termination of the SOS Call will turn off the green
LED light on the Rearview Mirror.

IN CASE OF EMERGENCY

353

2. The LED light located between the ASSIST and SOS

buttons on the Rearview Mirror will turn green once a
connection to a SOS operator has been made.

3. Once a connection between the vehicle and a SOS

operator is made, the SOS Call system may transmit the
following important vehicle information to a SOS op-
erator:

• Indication that the occupant placed a SOS Call.
• The vehicle brand.
• The last known GPS coordinates of the vehicle.

4. You should be able to speak with the SOS operator

through the vehicle audio system to determine if addi-
tional help is needed.

WARNING!

ALWAYS obey traffic laws and pay attention to the road.
ALWAYS drive safely with your hands on the steering
wheel. You have full responsibility and assume all risks
related to the use of the features and applications in this
vehicle. Only use the features and applications when it
is safe to do so. Failure to do so may result in an accident
involving serious injury or death.

NOTE:

• Your vehicle may be transmitting data as authorized

by the subscriber.

• Once a connection is made between the vehicle’s SOS

Call system and the SOS operator, the SOS operator
may be able to open a voice connection with the
vehicle to determine if additional help is needed. Once
the SOS operator opens a voice connection with the
vehicle’s SOS Call system, the operator should be able
to speak with you or other vehicle occupants and hear
sounds occurring in the vehicle. The vehicle’s SOS Call
system will attempt to remain connected with the SOS
operator until the SOS operator terminates the connec-
tion.

5. The SOS operator may attempt to contact appropriate

emergency responders and provide them with impor-
tant vehicle information and GPS coordinates.

WARNING!

• If anyone in the vehicle could be in danger (e.g., fire

or smoke is visible, dangerous road conditions or
location), do not wait for voice contact from an

(Continued)

IN CASE OF EMERGENCY

WARNING! (Continued)

Emergency Services Agent. All occupants should exit
the vehicle immediately and move to a safe location.

• Never place anything on or near the vehicle’s operable

network and GPS antennas. You could prevent oper-
able network and GPS signal reception, which can
prevent your vehicle from placing an emergency call.
An operable network and GPS signal reception is
required for the SOS Call system to function properly.

• The SOS Call system is embedded into the vehicle’s

electrical system. Do not add aftermarket electrical
equipment to the vehicle’s electrical system. This
may prevent your vehicle from sending a signal to
initiate an emergency call. To avoid interference that
can cause the SOS Call system to fail, never add
aftermarket equipment (e.g., two-way mobile radio,
CB radio, data recorder, etc.) to your vehicle’s electri-
cal system or modify the antennas on your vehicle. IF
YOUR VEHICLE LOSES BATTERY POWER FOR
ANY REASON (INCLUDING DURING OR AFTER
AN ACCIDENT), THE UCONNECT FEATURES,
APPS AND SERVICES, AMONG OTHERS, WILL
NOT OPERATE.

(Continued)

WARNING! (Continued)

• Modifications to any part of the SOS Call system

could cause the air bag system to fail when you need
it. You could be injured if the air bag system is not
there to help protect you.

SOS Call System Limitations

Vehicles sold in Mexico DO NOT have SOS Call system
capabilities.

SOS or other emergency line operators in Mexico may not
answer or respond to SOS system calls.

If the SOS Call system detects a malfunction, any of the
following may occur at the time the malfunction is de-
tected, and at the beginning of each ignition cycle:
• The Rearview Mirror light located between the ASSIST

and SOS buttons will continuously be illuminated red.

• The Device Screen will display the following message

“Vehicle device requires service. Please contact your
dealer.”

• An In-Vehicle Audio message will state “Vehicle device

requires service. Please contact your dealer.”

IN CASE OF EMERGENCY

355

WARNING!

• Ignoring the Rearview Mirror light could mean you

will not have SOS Call services. If the Rearview
Mirror light is illuminated, have your authorized
dealer service the SOS Call system immediately.

• The Occupant Restraint Control module turns on the

air bag Warning Light on the instrument panel if a
malfunction in any part of the system is detected. If
the Air Bag Warning Light is illuminated, have your
authorized dealer service the Occupant Restraint
Control system immediately.

Even if the SOS Call system is fully functional, factors
beyond FCA US LLC’s control may prevent or stop the SOS
Call system operation. These include, but are not limited
to, the following factors:
• Delayed accessories mode is active.
• The ignition is in the OFF position.
• The vehicle’s electrical systems are not intact.
• The SOS Call system software and/or hardware are

damaged during a crash.

• The vehicle battery loses power or becomes discon-

nected during a vehicle crash.

• LTE (voice/data) or 4G (data) network and/or Global

Positioning Satellite signals are unavailable or ob-
structed.

• Equipment malfunction at the SOS operator facility.
• Operator error by the SOS operator.
• LTE (voice/data) or 4G (data) network congestion.
• Weather.
• Buildings, structures, geographic terrain, or tunnels.

WARNING!

356

IN CASE OF EMERGENCY

NOTE:
• Your vehicle may be transmitting data as authorized by

Bulb Replacement

High Intensity Discharge Headlamps (HID) — If
Equipped

The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed. Because of this,
you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to an
authorized dealer for service.

358

IN CASE OF EMERGENCY

WARNING!

A transient high voltage occurs at the bulb sockets of
High Intensity Discharge (HID) headlamps when the
headlamp switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.

NOTE:

On vehicles equipped with High Intensity Dis-

charge (HID) headlamps, when the headlamps are turned
on, there is a blue hue to the lamps. This diminishes and
becomes more white after approximately 10 seconds, as the
system charges.

FUSES

WARNING!

• When replacing a blown fuse, always use an appro-

priate replacement fuse with the same amp rating as
the original fuse. Never replace a fuse with another
fuse of higher amp rating. Never replace a blown
fuse with metal wires or any other material. Do not
place a fuse inside a circuit breaker cavity or vice
versa. Failure to use proper fuses may result in
serious personal injury, fire and/or property damage.

• Before replacing a fuse, make sure that the ignition is

off and that all the other services are switched off
and/or disengaged.

• If the replaced fuse blows again, contact an autho-

rized dealer.

• If a general protection fuse for safety systems (air

bag system, braking system), power unit systems
(engine system, transmission system) or steering
system blows, contact an authorized dealer.
