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.

• 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.
