2012 JEEP GRAND CHEROKEE light

• The Quadra-Lift™ air suspension system uses a lifting and loweringpattern which keeps the headlights from shining into oncoming traffic.
When raising the vehicle, the rear of the vehicle will move up first and
then the front. When lowering the vehicle, the front will move down first
and then the rear.
• After the engine is turned off, you may notice that the air suspension system operates briefly. This is normal. The system is correcting the
position of the vehicle.
• To assist with changing a spare tire, the Quadra-Lift™ air suspension system has a feature which allows the automatic leveling to be disabled.
Press and hold both the “Up” and “Down” buttons simultaneously
between 5 and 10 seconds; a message will appear in the EVIC stating
leveling has been disabled immediately after both buttons have been
released. Driving the vehicle over 5 mph (8 km/h) will return the air
suspension to normal operation.
• An audible chime will be heard whenever a system error has been detected.
Operation • Pressing the “Up” or “Down” button once will move the suspension one position higher or lower from the current position, assuming all
conditions are met (i.e., engine running and all doors and liftgate closed).
• The 4 indicator lamps will illuminate to show the current position of the vehicle. Flashing indicator lamps will show a position which the system is
working to achieve. If multiple indicator lamps are flashing on the “Up”
button, the highest flashing indicator lamp is the position the system is
working to achieve.
• Normal Ride Height (NRH) – This is the standard position ofthe suspension and is meant for normal driving. Only the
bottom Indicator lamp on the “Up” button will be illuminated
when the vehicle is in this position.
• Off-Road 1 (OR1) (Raises the vehicle approximately 1.3 in (33 mm) – This position is intended for off-road driving only
where vehicle speeds may go above 25 mph (40 km/h). Press
the “Up” button once from NRH while vehicle speed is below
48 mph (77 km/h). The bottom two Indicator lamps on the
“Up” button will be illuminated when the vehicle is in OR1.
• Off-Road 2 (OR2) (Raises the vehicle approximately 2.6 in (65 mm) – This position is intended for off-road driving where
maximum ground clearance is required. Press the “Up” button
twice from NRH, or once from OR1 position while vehicle
speed is below 20 mph (32 km/h). All three Indicator lamps on
the “Up” button will be illuminated when the vehicle is in OR2.

TOW/HAUL MODE
• When driving in hilly areas, towing a trailer, carrying a heavy load, etc.,and frequent transmission shifting occurs, press the TOW/HAUL switch
to select TOW/HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due to excessive
shifting. When operating in TOW/HAUL mode, transmission upshifts are
delayed, and the transmission will automatically downshift (for engine
braking) during steady braking maneuvers.
• The “TOW/HAUL Indicator Light”will illuminate in the instrument
cluster to indicate that
TOW/HAUL mode has been
activated. Pressing the switch a
second time restores normal
operation. If the TOW/HAUL mode
is desired, the switch must be
pressed each time the engine is
started.

the EVIC (Electronic Vehicle Information Center).
• Start the engine and shift the transmission into REVERSE.
• Release the brake pedal for five seconds and ensure that there is no vehicle movement.
• Turn the engine off and firmly apply the parking brake.
• Shift the transmission into PARK and remove the Key Fob.
• Attach the vehicle to the tow vehicle using a suitable tow bar and release the parking brake.
NOTE: Vehicles equipped with Quadra-Lift™ must be lowered to the “Park”
(lowest) level, and have automatic leveling disabled, before tying them down
(from the body) on a trailer or a flatbed truck. Refer to “Quadra-Lift™” in
“Off-Road Capabilities” for more information. If the vehicle cannot be
lowered to the “Park” level (for example, engine will not run), tie-downs must
be fastened to the axles (not the body). Failure to follow these instructions
may cause fault codes to be set and/or loss of proper tie-down tension.
CAUTION!
• Towing with the rear wheels on the ground will cause severe transmission damage. Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
• Front or rear wheel lifts should not be used. Internal damage to the transmission or transfer case will occur if a front or rear wheel lift is
used when recreational towing.
• It is necessary to follow these steps to be certain that the transfer case is fully in NEUTRAL before recreational towing to prevent
damage to internal parts.

INSTRUMENT CLUSTER WARNING LIGHTS
- Tire Pressure Monitoring System (TPMS) Light
• Each tire, including the spare (if provided), should be checked monthly,when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
• As an added safety feature, your vehicle has been equipped with a Tire Pressure Monitoring System (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
• IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE,
ADJUST THE AIR PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE
SHOWN ON THE VEHICLE PLACARD OR TIRE INFLATION PRESSURE
LABEL LOCATED ON THE DRIVER'S DOOR. NOTE: AFTER INFLATION,
THE VEHICLE MAY NEED TO BE DRIVEN FOR 20 MINUTES BEFORE
THE FLASHING LIGHT WILL TURN OFF.
• Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
WHAT TO DO IN EMERGENCIES
97

• Your vehicle has also been equipped with a TPMS malfunction indicatorto indicate when the system is not operating properly. The TPMS
malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously illuminated. This
sequence will continue each time the vehicle is restarted as long as the
malfunction exists.
• When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
NOTE: Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C)
of air temperature change. Keep this in mind when checking tire pressure
inside a garage, especially in the Winter. Example: If garage temperature is
68°F (20°C) and the outside temperature is 32°F (0°C), then the cold tire
inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi
(7 kPa) for every 12°F (7°C) for this outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and
wheels. TPMS pressures and warning have been established for the
tire size equipped on your vehicle. Undesirable system operation or
sensor damage may result when using replacement equipment that is
not of the same size, type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to the sensors may
result.
BRAKE- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or the parking brake is applied. If the light is on and the
parking brake is not applied, it indicates a possible brake hydraulic
malfunction, brake booster problem or an Anti-Lock Brake System
problem.
• Please have your vehicle serviced immediately.
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.

- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality,etc., may illuminate the MIL after engine start. The vehicle should be
serviced if the light stays on through several typical driving cycles. In
most situations, the vehicle will drive normally and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic
converter damage. We recommend you do not operate the vehicle. Have
the vehicle serviced immediately.
- Electronic Stability Control (ESC) Activation/MalfunctionIndicator Light
• If the “ESC Activation/Malfunction Indicator Light” comes on
continuously with the engine running, a malfunction has been detected
in the ESC system. If this light remains on after several ignition cycles,
and the vehicle has been driven several miles (kilometers) at speeds
greater than 30 mph (48 km/h), we recommend you drive to the nearest
service center and have the vehicle serviced immediately.
• The “ESC Activation/Malfunction Indicator Light” starts to flash as soon as the tires lose traction and the ESC system becomes active. If the light
begins to flash during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed and driving to
the prevailing road conditions. The light also flashes when TCS is active.
To improve the vehicle's traction when starting off in deep snow, sand or
gravel, it may be desirable to switch the ESC system to Partial Off mode
by momentarily pressing the ESC Off
switch located below the
climate controls, on the switch panel.
- Charging System Light
• This light shows the status of the electrical charging system. If the charging system light remains on, it means that the vehicle is
experiencing a problem with the charging system.
• We recommend you do not continue driving if the charging system light is on. Have the vehicle serviced immediately.
- Oil Pressure Warning Light
• This light indicates low engine oil pressure. If the light turns on whiledriving, stop the vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns on.
• We recommend you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
• This light monitors the Anti-Lock Brake System (ABS).
• If the light is not on during starting, stays on, or turns on while driving,we recommend you drive to the nearest service center and have the
vehicle serviced immediately.
