OFF-ROAD CAPABILITIES (4WD OPERATION)

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
• 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 sys-
tem uses a lifting and lowering pattern
which keeps the headlights from shin-
ing 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. The feature controls are located in the radio screen. 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 of the
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.
