Quadra-Lift - Jeep Grand Cherokee User Manual

OFF-ROAD CAPABILITIES
• 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. Use
for low speed obstacles such as large rocks, deep ruts, etc.

QUADRA-LIFT™

• The Quadra-Lift™ air suspension sys-
tem 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 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.
