ABS JEEP GRAND CHEROKEE 2013 Owner handbook (in English)

Gas props support the liftgate in the open
position. However, because the gas pressure
drops with temperature, it may be necessary to
assist the props when opening the liftgate in
cold weather.
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 Driver Side Knee Air Bag
• Supplemental Side Air Bag Inflatable Cur-
tains (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/blockers for front seat occupant
• 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 and
front passenger) 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 passen-
gers as safe as possible.
If you will be carrying children too small for
adult-sized seat belts, the seat belts or the ISO-
FIX feature also can be used to hold infant and
child restraint systems. Refer to ISOFIX — Child
Seat Anchorage System for more information.
NOTE:
The Advanced Front Air Bags have a multi-
stage inflator design. This allows the air bag
to have different rates of inflation based on
several factors, including the severity and
type of collision.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air
bag:
1. Children 12 years old and under should
always ride buckled up in a rear seat.
WARNING!
Infants in rear facing child restraints should
never ride in the front seat of a vehicle with a
passenger Advanced Front Air Bag. An air
bag deployment can cause severe injury or
death to infants in that position.
Children that are not big enough to wear the
vehicle seat belt properly (see section on Child
Restraints) should be secured in the rear seat in
child restraints or belt-positioning booster seats.

NOTE:
This system will not activate until the ve-
hicle is at or above 20 mph (32 km/h).
To Deactivate
1. Pull the multifunction lever toward you (or
rearward in car) to manually deactivate the
system (normal operation of low beams).
2. Push back on the multifunction lever once
again to reactivate the system.
Daytime Running Lights — If
Equipped
The Daytime Running Lights (low intensity)
come on whenever the engine is running, and
the transmission is not in the PARK position.
The lights will remain on until the ignition is
switched to the OFF or ACC position or the
parking brake is engaged. Also, if a turn signal is
activated, the DRL lamp on the same side of the
vehicle will turn off for the duration of the turn
signal activation. Once the turn signal is no
longer active, the DRL lamp will illuminate. The
headlight switch must be used for normal night-
time driving.Disabling The Daytime Running Lights
To disable the Daytime Running Lights open the
hood and located the Power Distribution Center
(PDC), located on the right side of the engine
compartment.
Open the PDC by pulling outward on the locking
tabs (one on each side) and pulling upward on
the cover.
Remove the left and right Daytime Running
Lamp relays and reinstall the PDC cover.

Remove your foot from the accelerator pedal. If
you do not, the vehicle may continue to accel-
erate beyond the set speed. If this occurs:
•The message “DRIVER OVERRIDE” will dis-
play in the EVIC.
• The system will not be controlling the dis-
tance between your vehicle and the vehicle
ahead. The vehicle speed will only be deter-
mined by the position of the accelerator
pedal.To CancelThe 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.
• The transmission is shifted into NEUTRAL.
• The Electronic Stability Control/Traction Con-
trol System (ESC/TCS) activates.
NOTE:
If ACC is resumed or set with the ESC/TCS
off, ESC will automatically be re-engaged.
To Turn OffThe system will turn off and erase the set speed
in memory if:
• You push the ON/OFF button.
• You turn OFF the ignition.
• You switch to Four-Wheel Drive Low.
Driver Override
Adaptive Cruise Control Cancelled
122

•Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket grilles. Doing so could cause an
ACC system failure or malfunction.
When the condition that deactivated the system
is no longer present, the system will return to
the “Adaptive Cruise Control Off” state and will
resume function by simply reactivating it.
NOTE:
• If the “Clean Radar Sensor In Front Of
Vehicle” message occurs frequently
(e.g. more than once on every trip) with-
out any snow, rain, mud, or other obstruc-
tion, have the radar sensor realigned at
your authorized dealer.
•
Installing a snow plow, front-end protector,
an aftermarket grille or modifying the grille
is not recommended. Doing so may block
the sensor and inhibit ACC operation.
Removing ACC Sensor For Off-Roading
NOTE:
When off-roading, it may be advisable to
remove the ACC sensor. The sensor is lo-
cated 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 attach-
ment 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 con-
nector 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.”
To reinstall the sensor and bracket assembly
reverse the process above. The fastener torque
required to assembly the bracket back to the
beam is 6.6 ft lbs (9 N·m).

12. Park/Headlight ON Indicator — If
EquippedThis indicator will illuminate when
the park lights or headlights are
turned on.
13. Seat Belt Reminder Light
When the ignition switch is first turned to
ON/RUN, this light will turn on for four to
eight seconds as a bulb check. During
the bulb check, if the driver or front
passenger’s seat belt is unbuckled, a chime will
sound. After the bulb check or when driving, if the
driver or front passenger seat belt remains un-
buckled, the Seat Belt Indicator Light will flash or
remain on continuously. Refer to “Occupant Re-
straints” in “Things To Know Before Starting Your
Vehicle” for further information.
14. Brake Warning Light
This light monitors various brake
functions, including brake fluid
level and parking brake applica-
tion. 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 Pro-
gram (ESP) system. In this case, the light will
remain on until the condition has been cor-
rected. 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 capacity 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 conditions. The vehicle should
have service performed, and the brake fluid
level checked.
If brake failure is indicated, immediate repair is
necessary.
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.
165

Vehicles equipped with the Anti-Lock Brake
System (ABS), are also equipped with Elec-
tronic 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 approximately two sec-
onds. 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 position.
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 sec-
onds.
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. 4 LOW
This light alerts the driver that the
vehicle is in the four-wheel drive
LOW mode. The front and rear drive-
shafts are mechanically locked to-
gether forcing the front and rear
wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide
increased torque at the wheels.
For further information on four-wheel drive op-
eration and proper use, refer to “Four-Wheel
Drive Operation” in “Starting And Operating”.
17. Speedometer
Indicates vehicle speed.
18. Fuel Door Reminder
The fuel pump symbol points to the
side of the vehicle where the fuel
door is located.

ELECTRONIC BRAKE
CONTROL SYSTEM
Your vehicle is equipped with an advanced elec-
tronic brake control system that includes the
Anti-Lock Brake System (ABS), Traction Control
System (TCS), Brake Assist System (BAS), Elec-
tronic Roll Mitigation (ERM), and Electronic Sta-
bility Control (ESC). All five of these systems work
together to enhance vehicle stability and control in
various driving conditions.
Also, your vehicle is equipped with Trailer Sway
Control (TSC), Hill Start Assist (HSA), Brake
Lock Differential (BLD), Ready Alert Braking,
Rain Brake Support and, if it has four-wheel
drive with the MP 3023 two-speed transfer
case, Hill Descent Control (HDC).
Anti-Lock Brake System (ABS)This system aids the driver in maintaining ve-
hicle control under adverse braking conditions.
The system controls hydraulic brake pressure
to prevent wheel lock-up and help avoid skid-
ding on slippery surfaces during braking. Refer
to “Anti-Lock Brake System” in “Starting and
Operating” for further information.
WARNING!
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. The ABS cannot prevent
collisions, including those resulting from ex-
cessive speed in turns, driving on very slip-
pery surfaces, or hydroplaning. The capabili-
ties of an ABS-equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
Traction Control System (TCS)This system monitors the amount of wheel spin
of each of the driven wheels. If wheel spin is
detected, brake pressure is applied to the slip-
ping wheel(s) and engine power is reduced to
provide enhanced acceleration and stability.
A feature of the TCS system, 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 drivenaxle is spinning faster than the other, the sys-
tem will apply the brake of the spinning wheel.
This will allow more engine torque to be applied
to the wheel that is not spinning. This feature
remains active even if ESC system is in the
“Partial Off” mode. Refer to “Electronic Stability
Control (ESC)” in this section for further infor-
mation.
Brake Assist System (BAS)The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system 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 comple-
ments the anti-lock brake system (ABS). Apply-
ing the brakes very quickly results in the best
BAS assistance. To receive the benefit of the
system, you must apply
continuousbraking
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!
•Use only refrigerants and compressor lu-
bricants approved by the manufacturer for
your air conditioning system. Some unap-
proved refrigerants are flammable and can
explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs.
• The air conditioning system contains re-
frigerant under high pressure. To avoid risk
of personal injury or damage to the sys-
tem, adding refrigerant or any repair re-
quiring lines to be disconnected should be
done by an experienced repairman.
NOTE:
Use only manufacturer approved A/C Sys-
tem Sealers, Stop Leak Products, Seal Con-
ditioners, Compressor Oil, and Refrigerants. Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydro-
fluorocarbon (HFC) that is endorsed by the
Environmental Protection Agency and is an
ozone-saving product. However, the manufac-
turer recommends that air conditioning service
be performed by authorized dealer or other
service facilities using recovery and recycling
equipment.
NOTE:
Use only manufacturer approved A/C sys-
tem sealers, stop leak products, seal condi-
tioners, compressor oil, and refrigerants.
A/C Air Filter
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
WARNING!
Do not remove the A/C air filter while the
blower is operating or personal injury may
result.The A/C air filter is located in the fresh air inlet
behind the glove box. Perform the following
procedure to replace the filter:
1. Open the glove compartment and remove all
contents.
2. Push in on the sides of the glove compart-
ment and lower the door.
3. Pivot the glove compartment downward.
4. Disengage the two retaining tabs that secure
the filter cover to the HVAC housing, and re-
move the cover.

5. Remove the A/C air filter by pulling it straight
out of the housing.
6. Install the A/C air filter with the arrow on the
filter pointing toward the floor. When installing
the filter cover, make sure the retaining tabs
fully engage the cover.
CAUTION!
The A/C air filter is identified with an arrow to
indicate airflow direction through the filter.
Failure to properly install the filter will result
in the need to replace it more often.
7. Rotate the glove compartment door back
into position.
Body LubricationLocks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, sliding doors and
hood hinges, should be lubricated periodically
with a lithium based grease, such as MOPAR®
Spray White Lube to assure quiet, easy opera-
tion and to protect against rust and wear. Prior
to the application of any lubricant, the parts
concerned should be wiped clean to remove
dust and grit; after lubricating excess oil and
grease should be removed. Particular attention
should also be given to hood latching compo-
nents to ensure proper function. When perform-
ing other underhood services, the hood latch,
release mechanism and safety catch should be
cleaned and lubricated.
The external lock cylinders should be lubricated
twice a year, preferably in the Fall and Spring.
Apply a small amount of a high quality lubricant,
such as MOPAR® Lock Cylinder Lubricant di-
rectly into the lock cylinder.Windshield Wiper BladesClean the rubber edges of the wiper blades and
the windshield periodically with a sponge or soft
cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using the
wipers to remove salt or dirt from a dry wind-
shield.
Avoid using the wiper blades to remove frost or
ice from the windshield. Keep the blade rubber
out of contact with petroleum products such as
engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and fre-
quency of use. Poor performance of blades
may be present with chattering, marks, wa-
ter lines or wet spots. If any of these condi-
tions are present, clean the wiper blades or
replace as necessary.
