parking brake JEEP GRAND CHEROKEE 2009 WK / 3.G Owners Manual

If your Remote Keyless Entry (RKE) transmitter fails to
operate from a normal distance, check for these two
conditions.
1. A weak battery in the RKE transmitter. The expected
life of the battery is a minimum of three years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.
REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
328 ft (100 m).
How to Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK
•Doors closed
•Hood closed
•Liftgate closed
•Hazard switch off
•Brake switch inactive (brake pedal not pressed)
•Ignition key removed from ignition switch
•Battery at an acceptable charge level, and
•RKE PANIC button not pressed.
To Enter Remote Start Mode
Press and release the REMOTE START button
on the RKE transmitter twice, within five sec-
onds. The parking lights will flash and the horn
will chirp twice (if programmed). Then, the
engine will start and the vehicle will remain in the
Remote Start mode for a 15 minute cycle.

Child Restraints
Everyone in your vehicle needs to be buckled up all the
time — babies and children, too. Every state in the United
States, and all Canadian provinces, require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.
Children 12 years and under should ride properly buck-
led up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.
There are different sizes and types of restraints for
children from newborn size to the child almost large
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.

To Deactivate
1. Pull back on the multifunction lever to manually
deactivate the system (normal operation of low beams).
2. Push back on the multifunction lever once again to
reactivate the system.
NOTE:Broken, muddy, or obstructed headlights and
taillights of vehicles in the field of view will cause
headlights to remain on longer (closer to the vehicle).
Also, dirt, film, and other obstructions (sticker, toll box,
etc.) on the windshield or camera lens will cause the
system to function improperly.
Daytime Running Lights — If Equipped
The high beam headlights come on at a low intensity
level whenever the engine is running, and the transmis-
sion is not in the PARK position. The lights will remain
on until the ignition switch is turned to LOCK/ACC, or
the parking brake is engaged. The headlight switch must
be used for normal nighttime driving.
Automatic Headlight Leveling — HID Headlights
Only
This feature prevents the headlights from interfering
with the vision of oncoming drivers. Headlight leveling
automatically adjusts the height of the headlight beam in
reaction to changes in vehicle pitch.

INSTRUMENT CLUSTER DESCRIPTION
1. Speedometer
Indicates vehicle speed.
2. Brake Warning Light
This 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 a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Program (ESP) sys-
tem. In this case, the light will remain on until the
condition has been corrected. If the problem is related tothe 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
an accident. 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 position. The light should illuminate for approxi-
mately 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 position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
3. Turn Signal Indicator
The arrows will flash with the exterior turn signals
when the turn signal lever is operated. A tone will
chime if the turn signals are left on for more than one
mile (2 km).
4. High Beam Indicator
Indicates that headlights are on high beam.
5. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in

276 STARTING AND OPERATING

WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on the brake pedal,
the vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and when your foot is
firmly on the brake pedal.
Brake/Transmission Shift Interlock System
This system prevents you from moving the shift lever out
of PARK and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress thebrake
pedal first,before moving the shift lever out of PARK.
Brake/Transmission Interlock Manual Override
Your vehicle may be equipped with a shift lock manual
override. The manual override may be used in the event
that the shift lever should fail to move from PARK with
the key in the ON position and the brake pedal de-
pressed. To operate the shift lock manual override, per-
form the following steps:
1. Turn the key to the ON position without starting the
engine.
2. Firmly set the parking brake.
3. Using a flat blade screwdriver, carefully remove the
shift lock manual override cover, which is located on the
PRNDL bezel.
4. Depress and maintain firm pressure on the brake
pedal.

PARK
This gear position supplements the parking brake by
locking the transmission. The engine can be started in
this range. Never use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range. Always apply the parking brake
first, then place the shift lever into the PARK position.
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.

WARNING! (Continued)
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly forward
or in reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and when
your right foot is firmly on the brake pedal.
REVERSE
Use this range only after the vehicle has come to a
complete stop.
NEUTRAL
Shift into NEUTRAL when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.

Quadra-Trac IIOperating
Instructions/Precautions — If Equipped
The Quadra-Trac IItransfer case is fully automatic in the
normal driving 4WD HI mode. The Quadra-Trac II
transfer case provides three mode positions — 4WD HI,
NEUTRAL, and 4WD LOW.
This transfer case is fully automatic in the 4WD HI mode.
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. The 4WD LOW position is intended for
loose, slippery road surfaces only. Driving in the 4WD
LOW position on dry hard surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
