2011 JEEP GRAND CHEROKEE engine

•Sand/Mud – Off-road calibration
for use on low traction surfaces such
as mud, sand, or wet grass. Driveline
is maximized for traction. Some
binding may be felt on less forgiving
surfaces. The electronic brake controls
are set to limit traction control
management of throttle and wheel
spin.
• Rock – Off-road calibration only
available in 4WD Low range. The
vehicle is raised (if equipped with Air
Suspension) for improved ground
clearance. Traction based tuning with
improved steer-ability for use on high
traction off-road surfaces. Activates
the Hill Descent Control for steep
downhill control. Use for low speed
obstacles such as large rocks, deep
ruts, etc.
Quadra-Lift™
• The Quadra-Lift™ air suspension system provides full time load leveling
capability along with the benefit of
being able to adjust vehicle height by
the push of a button. Quadra-Lift™ is
available with both Quadra-Trac II
®
and Quadra-Drive II™.
• The system requires that the engine be running for all changes. When
lowering the vehicle all of the doors,
including the liftgate, must be closed. • The Quadra-Lift™ air suspension
system uses a lifting and lowering
pattern 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.

(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.
WARNING!
You or others could be injured if you
leave the vehicle unattended with the
transfer case in the NEUTRAL position
without first fully engaging the
parking brake. The transfer case
NEUTRAL position disengages both
the front and rear driveshafts from the
powertrain and will allow the vehicle
to move even if the transmission is in
PARK. The parking brake should
always be applied when the driver is
not in the vehicle.

• When the malfunction indicator is illuminated, the system may not be able to detect orsignal 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.
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 theparking 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.
• We recommend you drive to the nearest service center and have the 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., mayilluminate 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/Malfunction
Indicator 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

IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for overheating bytaking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the Temperature Control to maximum heat, the Mode Control to floor and the Fan Control to high. This allows the heater core to act as a supplement to the
radiator and aids in removing heat from the engine cooling system.
• If the temperature reading does not return to normal, turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam
from your radiator. If you see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool. Never try to open a cooling
system pressure cap when the radiator or coolant bottle is hot.
