2012 JEEP GRAND CHEROKEE service

INTRODUCTIONCongratulations on selecting your new Chrysler
Group LLC vehicle. Be assured that it repre-
sents precision workmanship, distinctive styl-
ing, and high quality - all essentials that are
traditional to our vehicles.
This is a specialized utility vehicle. It can go
places and perform tasks that conventional
passenger cars are not intended. It handles
and maneuvers differently from many passen-
ger cars both on-road and off-road, so take
time to become familiar with your vehicle.
The two-wheel drive version of this vehicle was
designed for on-road use only. It is not intended
for off-road driving or use in other severe con-
ditions suited for a four-wheel drive vehicle.
Before you start to drive this vehicle, read the
Owner’s Manual and all the Supplements. Be
sure you are familiar with all vehicle controls,
particularly those used for braking, steering,
and transmission and transfer case shifting.
Learn how your vehicle handles on different
road surfaces. Your driving skills will improve
with experience, but as in driving any vehicle,
take it easy as you begin. When driving off-roador working the vehicle, don’t overload it or
expect it to overcome the forces of nature.
Always observe local laws wherever you drive.
As with other vehicles of this type, failure to
operate this vehicle correctly may result in loss
of control or a collision. Be sure to read the
“On-Road/ Off-Road Driving Tips” in “Starting
And Operating” for further information.
NOTE:
After reviewing the owner information, it
should be stored in the vehicle for conve-
nient referencing and remain with the ve-
hicle when sold.
Failure to operate this vehicle correctly may
result in loss of control or a collision.
Operating this vehicle at excessive speeds or
while intoxicated may result in loss of control,
collision with other vehicles or objects, going
off the road, or overturning; any of which may
lead to serious injury or death. Also, failure to
use seat belts subjects the driver and passen-
gers to a greater risk of injury or death.
To keep your vehicle running at its best, have
your vehicle serviced at recommended inter-vals by an authorized dealer or distributor who
has the qualified personnel, special tools and
equipment to perform all service.
The manufacturer and its distributors are vitally
interested in your complete satisfaction with
this vehicle. If you encounter a service or
warranty problem which is not resolved to your
satisfaction, discuss the matter with your autho-
rized dealer or distributor’s management.
Your authorized dealer or distributor will be
happy to assist you with any questions about
your vehicle.
ROLLOVER WARNINGUtility vehicles have a significantly higher roll-
over rate than other types of vehicles. This
vehicle has a higher ground clearance and a
higher center of gravity than many passenger
cars. It is capable of performing better in a
wide variety of off-road applications. Driven in
an unsafe manner, all vehicles can go out of
control. Because of the higher center of gravity,
if this vehicle is out of control it may roll over
when some other vehicles may not.

Do not attempt sharp turns, abrupt maneuvers,
or other unsafe driving actions that can cause
loss of vehicle control. Failure to operate this
vehicle safely may result in a collision, rollover
of the vehicle, and severe or fatal injury. Drive
carefully.
Failure to use the driver and passenger seat
belts provided is a major cause of severe or
fatal injury. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt. Always buckle up.IMPORTANT NOTICEALL MATERIAL CONTAINED IN THIS PUBLI-

In view of the many replacement parts and
accessories from various manufacturers avail-
able on the market, the manufacturer cannot be
certain that the driving safety of your vehicle
will not be impaired by the attachment or instal-
lation of such parts. Even if such parts are
officially-approved (for example, by a general
operating permit for the part or by constructing
the part in an officially approved design), or if
an individual operating permit was issued for
the vehicle after the attachment or installation
of such parts, it cannot be implicitly assumed
that the driving safety of your vehicle is unim-
paired. Therefore, neither experts nor official
agencies are liable. Therefore the manufacturer
only assumes responsibility when parts, which
are expressly authorized or recommended by
the manufacturer, are attached or installed at
an authorized dealer. The same applies when
modifications to the original condition are sub-
sequently made on the manufacturer’s ve-
hicles.Your warranties do not cover any part that the
manufacturer did not supply. Nor do they cover
the cost of any repairs or adjustments that
might be caused or needed because of the
installation or use of non-manufacturer parts,
components, equipment, materials, or addi-
tives. Nor do your warranties cover the costs of
repairing damage or conditions caused by any
changes to your vehicle that do not comply with
the manufacturers specifications.
Original Mopar
parts and accessories and
other products approved by the manufacturer,
including qualified advice, are available at your
authorized dealer.
When it comes to service, remember that your
authorized dealer knows your vehicle best, has
the factory-trained technicians and genuine
Mopar parts, and is interested in your satis-
faction.

become trapped temporarily in the igni-
tion switch. If this occurs, place the shift
lever in PARK, rotate the key to the right
slightly, then remove the Key Fob as de-
scribed. If a malfunction occurs, the sys-
tem may trap the key in the ignition switch
to warn you that this safety feature is
inoperable. The engine can be started and
stopped, but the Key Fob cannot be re-
moved until you obtain service.
• The power window switches, radio, power
sunroof (if equipped), and power outlets
will remain active for up to 10 minutes

Emergency Key Removal
13

The system uses the factory-mated Key Fob
with Remote Keyless Entry (RKE) transmitter
and Wireless Ignition Node (WIN) to prevent
unauthorized vehicle operation. Therefore, only
Key Fobs that are programmed to the vehicle
can be used to start and operate the vehicle.
The system will shut the engine off in two
seconds if an invalid Key Fob is used to start
the engine.
After turning the ignition switch to the ON/RUN
position, the Vehicle Security Light will turn on
for three seconds for a bulb check. If the light
remains on after the bulb check, it indicates
that there is a problem with the electronics. In
addition, if the light begins to flash after the
bulb check, it indicates that someone used an
invalid Key Fob to start the engine. Either of
these conditions will result in the engine being
shut off after two seconds.
If the Vehicle Security Light turns on during
normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there
is a fault in the electronics. Should this occur,
have the vehicle serviced as soon as possible
by an authorized dealer.CAUTION!
The Sentry KeyImmobilizer system is not
compatible with some after-market remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.
All of the Key Fobs provided with your new
vehicle have been programmed to the vehicle
electronics.
Replacement Keys
NOTE:
Only Key Fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a Key Fob is
programmed to a vehicle, it cannot be pro-
grammed to any other vehicle.
CAUTION!
• Always remove the Key Fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.

WARNING!(Continued)
• Allowing children to be in a vehicle unat-
tended is dangerous for a number of rea-
sons. A child or others could be seriously or
fatally injured. Children should be warned
not to touch the parking brake, brake pedal
or the shift lever
• Do not leave the key fob in or near the
vehicle, and do not leave Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.

Automatic Locking Retractor Mode
(ALR) — If Equipped
In this mode, the shoulder belt is automatically
pre-locked. The belt will still retract to remove
any slack in the shoulder belt. The Automatic
Locking Mode is available on all rear
passenger-seating positions with a combina-
tion lap/shoulder belt. Use the Automatic Lock-
ing Mode anytime a child safety seat is installed
in a seating position that has a belt with this
feature. Children 12 years old and under
should always be properly restrained in the rear
seat.
How To Engage The Automatic Locking
Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down-
ward until the entire belt is extracted.
3. Allow the belt to retract. As the belt retracts,
you will hear a clicking sound. This indicates
the safety belt is now in the Automatic Locking
Mode.How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.
WARNING!
•
The belt and retractor assembly must be
replaced if the seat belt assembly Auto-
matic Locking Retractor (ALR) feature or
any other seat belt function is not working
properly when checked according to the
procedures in the Service Manual.
• Failure to replace the belt and retractor
assembly could increase the risk of injury in
collisions.
Energy Management FeatureThis vehicle has a safety belt system with an
Energy Management feature in the front seating
positions to help further reduce the risk of injury
in the event of a head-on accident. This safety belt system has a retractor assem-
bly that is designed to release webbing in a
controlled manner. This feature is designed to
help reduce the belt force acting on the occu-
pant’s chest.
Seat Belt PretensionersThe seat belts for both front seating positions
are equipped with pretensioning devices that
are designed to remove slack from the seat belt
in the event of an accident. These devices may
improve the performance of the seat belt by
assuring that the belt is tight about the occu-
pant early in an accident. Pretensioners work
for all size occupants, including those in child
restraints.
NOTE:
These devices are not a substitute for
proper seat belt placement by the occupant.
The seat belt still must be worn snugly and
positioned properly.
The pretensioners are triggered by the Occu-
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items. A
deployed pretensioner or a deployed air bag
must be replaced immediately.

Inflatable Curtain (SABIC), Supplemental Seat-
Mounted Side Air Bags (SAB), and front seat
belt pretensioners, as required, depending on
the severity and type of impact.
Advanced Front Air Bags and Supplemental
Driver Side Knee Air Bag are designed to
provide additional protection by supplementing
the seat belts in certain frontal collisions de-
pending on the severity and type of collision.
Advanced Front Air Bags are not expected to
reduce the risk of injury in rear, or side colli-
sions.
The Advanced Front Air Bags and Supplemen-
tal Driver Side Knee Air Bag will not deploy in all
frontal collisions, including some that may pro-
duce substantial vehicle damage — for ex-
ample, some pole collisions, truck underrides,
and angle offset collisions. On the other hand,
depending on the type and location of impact,
Advanced Front Air Bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
The side air bags will not deploy in all side
collisions. Side air bag deployment will depend
on the severity and type of collision.Because air bag sensors measure vehicle de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an air bag should have de-
ployed.
Seat belts are necessary for your protection in
all accidents, and also are needed to help keep
you in position, away from an inflating air bag.
The ORC monitors the readiness of the elec-
tronic parts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the key is in the LOCK position, in
the ACC position, or not in the ignition, the air
bag system is not on and the air bags will not
inflate.
The ORC contains a backup power supply
system that may deploy the air bags even if the
battery loses power or it becomes discon-
nected prior to deployment.
Also, the ORC turns on the Air Bag
Warning Light in the instrument
panel for approximately four to
eight seconds for a self-check
when the ignition is first turned to
the ON/RUN position. After the self-check, the Air Bag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A
single chime will sound if the light comes on
again after initial startup.
It also includes diagnostics that will illuminate
the instrument cluster Air Bag Warning Light if a
malfunction is noted that could affect the air
bag system. The diagnostics also record the
nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bags to protect you in a collision. If the
light does not come on as a bulb check when
the ignition is first turned on, stays on after
you start the vehicle, or if it comes on as you
drive, have an authorized dealer service the
air bag system immediately.
