passenger entry and exit as well as lowering the rear of
the vehicle for easier loading and unloading of cargo.
To enter Park Mode, press the “Down” button once
while the vehicle speed is below 25 mph (40 km/h).
Once the vehicle speed goes below 15 mph (24 km/h)
the vehicle height will begin to lower. If the vehicle
speed remains between 15 mph (24 km/h) and 25 mph
(40 km/h) for greater than 60 seconds, or the vehicle
speed exceeds 25 mph (40 km/h) the Park Mode
change will be cancelled. To exit Park Mode, press the
“Up” button once while in Park Mode or drive the
vehicle over 15 mph (24 km/h).
The Selec-Terrain™ switch will automatically change the
vehicle to the proper height based on the position of the
Selec-Terrain™ switch. The height can be changed from
the default Selec-Terrain™ setting by normal use of the
air suspension buttons. Refer to “Selec-Terrain™” in
“Starting and Operating” for further information.
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. If a door is opened
at any time while the vehicle is lowering the change will
not be completed until the open door(s) is closed.
The Quadra-Lift™ air suspension system uses a lifting
and lowering pattern which keeps the headlights from
incorrectly 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.
