NOTE:
Automatic lowering of the vehicle into Entry/Exit can
be enabled through the Uconnect Touchscreen
Radio by selecting the “Auto Entry/Exit” setting. If
this feature is enabled, the vehicle will only lower if
the gear selector is in PARK, the terrain switch is in
AUTO, the transfer case is in AUTO and the vehicle
level is either in Normal or Aero Height. The vehicle
will not automatically lower to Entry/Exit height if the
air suspension level is in OR2 or OR1. If the vehicle
is equipped with Intrusion Theft Module (ITM), the
lowering will be suppressed when the ignition is
switched OFF and the door is open to prevent set-
ting the alarm off.
The Selec-Terrain system 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
page 144.
The system requires that the engine be running for all
changes. When lowering the vehicle all of the doors
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/are 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.
After the engine is turned off, it may be noticed that the
air suspension system operates briefly; this is normal.
The system is correcting the position of the vehicle to
ensure a proper appearance.
To assist with changing a spare tire, the Quadra-Lift Air
Suspension system has a feature which allows the
automatic leveling to be disabled
page 199.
Default Ride Height
•
Select Aero Height or Normal Ride Height as the
default for all vehicle speeds and operation. This is
the selected height that the suspension will level for
speed changes (e.g. raising from Entry/Exit Height
at speed, lowering from Off Road Height at speed,
etc.).
•
Default ride height can be changed by manually
adjusting the ride height switch to Normal Ride
Height or Aero Height and staying in the selected
height for 2.5 seconds. It will be stored as the
default ride height and the height will be maintained
until a new default ride height is selected.
If equipped with a touchscreen radio, all enabling/
disabling of air suspension features must be done
through the radio
page 199.
WARNING!
The air suspension system uses a high pressure vol-
ume of air to operate the system. To avoid personal
injury or damage to the system, see an authorized
dealer for service.
