2009 JEEP GRAND CHEROKEE wheel

INTRODUCTION
This is a specialized utility vehicle designed for both
on-road and off-road use. It can go places and perform
tasks for which conventional two-wheel drive enclosed
vehicles were not intended. It handles and maneuvers
differently from many passenger cars both on-road and
off-road, so take time to become familiar with your
vehicle.
The two-wheel drive utility vehicle was designed for
on-road use only. It is not intended for off-road driving
or use in other severe conditions suited for a four-wheel
drive vehicle.
Before you start to drive this vehicle, read the Owner’s
Manual. Be sure you are familiar with all vehicle controls,
particularly those used for braking, steering, transmis-
sion, and transfer case shifting. Learn how your vehicle
handles on different road surfaces. Your driving skills
will improve with experience. When driving off-road orworking the vehicle, don’t overload the vehicle or expect
the vehicle to overcome the natural laws of physics.
Always observe federal, state, provincial and 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 an
accident. Refer to “On-Road/Off-Road Driving Tips” in
Section 5 of this manual.
This manual has been prepared with the assistance of
service and engineering specialists to acquaint you with
the operation and maintenance of your vehicle. It is
supplemented by a Warranty Information Booklet and
various customer-oriented documents. You are urged to
read these publications carefully. Following the instruc-
tions and recommendations in this manual will help
assure safe and enjoyable operation of your vehicle.

WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and store the extender when not
needed.
Driver and Front Passenger Supplemental
Restraint Systems (SRS)
This vehicle has airbags for both the driver and right
front passenger as a supplement to the seat belt restraint
systems. The driver’s front airbag is mounted in the
steering wheel. The front passenger airbag is mounted in
the instrument panel, above the glove compartment. The
words SRS/AIRBAG are embossed on the airbag covers.NOTE:The front airbags are certified to the Federal
regulations that allow less forceful deployment.

2 — Passenger Airbag
3 — Knee Bolster 46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2. All occupants should use their lap and shoulder belts
properly.
3. The driver and front passenger seats should be moved
back as far as practical to allow the front airbags room to
inflate.
4. Do not lean against the door or window, airbags will
inflate forcefully into the space between you and the
door.
5. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided under “If
You Need Assistance” in Section 9 of this manual.WARNING!
•Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won’t deploy at all.
Always wear your seat belts even though you have
airbags.
•Being too close to the steering wheel or instrument
panel during airbag deployment could cause seri-
ous injury. Airbags need room to inflate. Sit back,
comfortably extending your arms to reach the
steering wheel or instrument panel.
•Side curtain airbags need room to inflate. Do not
lean against the door or window. Sit upright in the
center of the seat.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Control (ORC)
•Airbag Warning Light
•Driver Airbag
•Passenger Airbag
•Side Curtain Airbags above Side Windows
•Side Remote Acceleration Sensors
•Driver Side Seat Track Position Sensor
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Knee Impact Bolsters
•Front Acceleration Sensors
•Driver and Front Passenger Seat Belt Pretensioners
How the Airbag System Works
•
TheOccupant Restraint Control (ORC)determines if
a frontal, side, or rollover collision is severe enough to
require the front and/or side airbags to inflate. The
front airbag inflators are designed to provide different
rates of airbag inflation from direction provided by the
ORC. The ORC will detect roll overs, not rear impacts.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.

•The ORC also turns on the Airbag Warning
Light for 2.5 to 8 seconds for a self-check
when the ignition is first turned on. After the
self-check, the Airbag Warning Light will
turn off. If the ORC detects a malfunction in any part
of the system, it turns on the Airbag Warning Light
either momentarily or continuously. A single chime
will sound if the light comes on again after initial start
up.
WARNING!
Ignoring the Airbag Warning Light in your instru-
ment panel could mean you won’t have the airbags to
protect you in a collision. If the light does not come
on, stays on after you start the vehicle, or if it comes
on as you drive, have the airbag system checked right
away.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, based on collision severity and occupant
size. The steering wheel hub trim cover and the upper
right side of the instrument panel separate and fold
out of the way as the bags inflate to their full size. The
bags fully inflate in about 50 to 70 milliseconds. This is
about half of the time it takes to blink your eyes. The
bags then quickly deflate while helping to restrain the
driver and front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
airbag gas is vented through the vent holes in the sides
of the airbag. In this way, the airbags do not interfere
with your control of the vehicle.

NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured if the airbag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper or vehicle body struc-
ture.
(Continued)
WARNING! (Continued)
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has an airbag system.

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objectslodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

knob or from the steering wheel radio control (right
switch), if so equipped.
The radio display will be used for visual prompts from
the uconnectphone such asCELLor caller ID on
certain radios.
Operation
Voice commands can be used to operate the uconnect
phone and to navigate through the uconnectphone
menu structure. Voice commands are required after most
uconnectphone prompts. You will be prompted for a
specific command and then guided through the available
options.
•Prior to giving a voice command, one must wait for
the beep, which follows theReadyprompt or another
prompt.
•For certain operations, compound commands can be
used. For example, instead of sayingSetupand then
Phone Pairing,the following compound command
can be said:Setup Phone Pairing.
•For each feature explanation in this section, only the
combined form of the voice command is given. You
can also break the commands into parts and say each
part of the command when you are asked for it. For
example, you can use the combined form voice com-
mandPhonebook New Entry,or you can break the
combined form command into two voice commands:
PhonebookandNew Entry.Please remember, the
uconnectphone works best when you talk in a
normal conversational tone, as if speaking to someone
sitting a few feet/meters away from you.
