2013 JEEP GRAND CHEROKEE ABS

NOTE:
•The driver’s door key cylinder and the liftgate button
on the RKE transmitter cannot arm or disarm the
Vehicle Security Alarm.
• The Vehicle Security Alarm remains armed during
power liftgate entry. Pressing the liftgate button will
not disarm the Vehicle Security Alarm. If someone
enters the vehicle through the liftgate and opens any
door the alarm will sound.
• When the Vehicle Security Alarm is armed, the interior
power door lock switches will not unlock the doors.
The Vehicle Security Alarm is designed to protect your
vehicle; however, you can create conditions where the
system will give you a false alarm. If one of the previ-
ously described arming sequences has occurred, the
Vehicle Security Alarm will arm regardless of whether you are in the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this occurs,
disarm the Vehicle Security Alarm.
If the Vehicle Security Alarm is armed and the battery
becomes disconnected, the Vehicle Security Alarm will
remain armed when the battery is reconnected; the
exterior lights will flash, the horn will sound. If this
occurs, disarm the Vehicle Security Alarm.
Tamper Alert
If something has triggered the Vehicle Security Alarm in
your absence, the horn will sound three times and the
exterior lights blink three times when you unlock the
doors. Check the vehicle for tampering.
ILLUMINATED ENTRY
The courtesy lights will turn on when you use the
Remote Keyless Entry (RKE) transmitter to unlock the
doors or open any door.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 21

OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems:
•Three-point lap and shoulder belts for the driver and
all passengers
• Advanced Front Air Bags for driver and front
passenger
• Supplemental Active Head Restraints (AHR) located
on top of the front seats (integrated into the head
restraint)
• Supplemental Side Air Bag Inflatable Curtains (SABIC)
for the driver and passengers seated next to a window
• Supplemental Seat-Mounted Side Air Bags (SAB)
• An energy-absorbing steering column and steering
wheel •
Knee bolsters for front seat occupants
• Front seat belts incorporate pretensioners that may
enhance occupant protection by managing occupant
energy during an impact event
• All seat belt systems (except the driver ’s) include
Automatic Locking Retractors (ALRs), which lock the
seat belt webbing into position by extending the belt
all the way out and then adjusting the belt to the
desired length to restrain a child seat or secure a large
item in a seat — if equipped
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly, to keep you and your passengers as safe as
possible.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•The system will not be controlling the distance be-
tween your vehicle and the vehicle ahead. The vehicle

The system will disable ACC without erasing the
memory if:
• You softly tap the brake pedal.
• You depress the brake pedal.
• You press the CANCEL switch.
• The speed of the vehicle goes below 15 mph
(25 km/h).
• An Anti-Lock Brake System (ABS) event occurs.
• A Trailer Sway Control (TSC) event occurs.

Removing ACC Sensor For Off-Roading
NOTE:When off-roading, it may be advisable to remove
the ACC sensor. The sensor is located behind the front
lower grille in the center of the vehicle. After removing
the lower fascia, you may remove the lower sensor and
bracket assembly.
To remove the sensor follow these instructions:
1. Unplug the connector by depressing the two tabs on the connector and pulling it out. Do not pull by the
wiring or use any tools to remove the connector.
2. Remove the wiring christmas tree attachment from the back of the bracket.
3. Remove the two M6 fasteners that connect the bracket to the bumper. NOTE:
Do not change the adjustment fasteners or pull
the sensor off of the bracket. Doing so may misalign the
sensor.
Store the sensor and bracket assembly in a safe location.
The wiring and connector must be stowed properly after
the sensor and bracket assembly is removed.
A connector plug is stowed on top of the bumper beam.
Insert the wiring connector into the connector plug.
NOTE: When the sensor is removed, Adaptive Cruise
Control, Normal Cruise Control, and Forward Collision
Warning will not be available. The cluster will display
the warning “ACC/FCW Unavailable - Service Radar
Sensor.”

14. Brake Warning LightThis light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop. The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer. The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
15. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns 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 system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock

brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.
16. Speedometer
Indicates vehicle speed.
17. Sport ModeThis light will illuminate when the sport mode
or track mode is selected. These modes provide
performance based tuning with improved han-
dling and acceleration through an electronic
controlled dampening system. This system reduces body
roll and pitch in many driving situations including
cornering, acceleration and braking.
18. Fuel Door Reminder
The fuel pump symbol points to the side of the
vehicle where the fuel door is located. 19. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON/RUN position.
20. Electronic Vehicle Information Center (EVIC) White
Telltale Area
This area will display the EVIC reconfigurable white
telltales. For further information, refer to “Electronic
vehicle Information Center (EVIC)”.
21. Electronic Vehicle Information Center (EVIC) Amber
Telltale Area
This area will display the EVIC reconfigurable amber
caution telltales. For further information, refer to “Elec-
tronic vehicle Information Center (EVIC)”.
