SELEC-TERRAIN™
• Selec-Terrain™ combines the capabilities of the vehicle control systems,along with driver input, to provide the best performance for all terrains.
Rotate the mode control knob to select the following Selec-Terrain™
positions: •Sport – Dry weather, on-road calibration. Only available in 4WD High
range. Performance-based tuning that provides a rear wheel drive feel
but with improved handling and acceleration over a two-wheel drive
vehicle. The Electronic Stability Control will set to allow more driver
control of the vehicle while maintaining safe handling controls. The
vehicle will lower (if equipped with Air Suspension) by 0.59 inches
(15 mm) in the SPORT mode.
• Snow – The Electronic Stability Control is set for additional stability in
inclement weather. Use on and off road on loose traction surfaces such
as snow.
• Auto – Fully automatic full-time four-wheel drive operation can be used
on and off road. Balances traction with steering feel to provide improved
handling and acceleration over two-wheel drive vehicles.
• 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.
OFF-ROAD CAPABILITIES

• 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.

AUTOSTICK®
• AutoStick® is a driver-interactivetransmission feature that offers
manual gear shifting to provide
youwithmorecontrolofthe
vehicle. AutoStick® allows you to
maximize engine braking,
eliminate undesirable upshifts and
downshifts, and improve overall
vehicle performance.
• This system can also provide you with more control during passing,
city driving, cold slippery
conditions, mountain driving,
trailer towing, and many other
situations.
Operation
• When the shift lever is in the DRIVE position, the transmission willoperate automatically, shifting between the five available gears. To
engage AutoStick®, simply tap the shift lever to the right or left (+/-)
while in the DRIVE position, or tap one of the steering wheel-mounted
shift paddles (+/-). Tapping (-) to enter AutoStick® mode will downshift
the transmission to the next lower gear, while using (+) to enter
AutoStick® mode will retain the current gear. When AutoStick® is active,
the current transmission gear is displayed in the instrument cluster. In
AutoStick® mode, the transmission will shift up or down when (+/-) is
manually selected by the driver (using the shift lever, or the shift
paddles), unless an engine lugging or overspeed condition would result.
It will remain in the selected gear until another upshift or downshift is
chosen, except as described below:
• Normally, in AutoStick® mode, the transmission will automatically shift up when maximum engine speed is reached. If, h owever, AutoStick® is
engaged while in SPORT mode, the transmission will remain in the
selected gear even when maximum engine speed is reached. The
transmission will upshift only when commanded by the driver.
• The transmission will automatically downshift as the vehicle slows (to prevent engine lugging) and will display the current gear.
• The transmission will automatically downshift to first gear when coming to a stop. After a stop, the driver should manually upshift (+) the
transmission as the vehicle is accelerated.
• You can start out in first or second gear. Tapping (+) (at a stop) will allow starting in second gear. Starting out in second gear is helpful in
snowy or icy conditions.
• The system will ignore attempts to upshift at too low of a vehicle speed.
• Avoid using speed control when AutoStick® is engaged.

• Transmission shifting will be more noticeable when AutoStick® isengaged.
• To disengage AutoStick® mode, hold the shift lever to the right or press and hold the (+) shift paddle until “D” is once again displayed in the
instrument cluster. You can shift in or out of the AutoStick® mode at any
time without taking your foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a slippery surface.
The drive wheels could lose their grip and the vehicle could skid,
causing a collision or personal injury.

- 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

• If a problem is detected, the light will come on while the engine is running. Cycle the ignition key when the vehicle has completely stopped
and the shift lever is placed in the PARK position; the light should turn
off.
• If the light remains lit with the engine running, your vehicle will usually be drivable; however, see an authorized service center i mmediately. If the
light is flashing when the engine is running, immediate service is required
and you may experience reduced performance, an elevated/rough idle or
engine stall and your vehicle may require towing.
- Air Bag Warning Light
• If the light is not on during starting, stays on, or turns on while driving, have the vehicle serviced by an authorized service center immediately.
Fuel Cap/Loose Gas Cap Message
• If a “gas cap” message (shown as Check Gascap) appears, tighten thegas cap until a “clicking” sound is heard.
• If the message continues to appear for more than three days after tightening the gas cap, have the vehicle serviced by an authorized
service center immediately.

IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential foroverheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in 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 blower 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.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the
temperature gauge reads 240°F (116 °C) or greater pull over and stop
the vehicle. Idle the vehicle with the air conditioner turned off until the
pointer drops back into the normal range 200–230°F (93–110°C). If
the pointer remains at 240°F (116°C) or greater and you hear a chime,
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.
