OR1 position only, if the vehicle speed remains
between 40 mph (64 km/h) and 50 mph (80 km/h)
for greater than 20 seconds or if the vehicle speed
exceeds 50 mph (80 km/h), the vehicle will be auto-
matically lowered to NRH
page 167. OR1 is
unavailable on 4x2 air suspension vehicles.
•
Off-Road 2 (OR2) (Raises the vehicle approximately
2.0 inches [51 mm]) – This position is intended for
off-roading use only where maximum ground clear-
ance is required. To enter OR2, push the toggle
switch forward twice from the NRH position or once
from the OR1 position while vehicle speed is below
20 mph (32 km/h). While in OR2, if the vehicle
speed exceeds 25 mph (40 km/h) the vehicle height
will be automatically lowered to OR1
page 167.
OR2 is unavailable on 4x2 air suspension vehicles.
•
Aero Height (Lowers the vehicle approximately
-0.6 inches [-15 mm]) – This position provides
improved aerodynamics by lowering the vehicle. The
vehicle will automatically enter Aero Height when
the vehicle speed remains between 62 mph
(100 km/h) and 66 mph (106 km/h) for greater
than 20 seconds or if the vehicle speed exceeds
66 mph (106 km/h). The vehicle will return to
Default Ride Height from Aero Height if the vehicle
speed remains between 30 mph (48 km/h) and
35 mph (56 km/h) for greater than 20 seconds or if
the vehicle speed falls below 30 mph (48 km/h).
The vehicle will enter Aero Height, regardless of
vehicle speed if the vehicle is in “SPORT” mode.
•
Entry/Exit Height (Lowers the vehicle approximately
-1.6 inches [-40 mm]) – This position lowers the
vehicle for easier passenger entry and exit as well
as lowering the rear of the vehicle for easier loading
and unloading of cargo. To enter Entry/Exit Height,
push the toggle switch down twice from NRH while
the vehicle speed is below 6 mph (10 km/h). To exit
Entry/Exit Height, push the UP button once while in
Entry/Exit Height or drive the vehicle over 4 mph
(6 km/h).
NOTE:
Automatic lowering of the vehicle into Entry/Exit
Height can be enabled through the Uconnect Touch-
screen Radio. 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
if the air suspension level is in OR2 or OR1. When
towing, the automatic Entry/Exit feature may be dis-
abled through the Uconnect Touchscreen Radio to
prevent vehicle and trailer movement when gear
selector is moved to PARK.
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 117.
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/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 170.
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 Quadra-Lift switch to Normal Ride
Height or Aero Ride Height and stay 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.
NOTE:
If equipped with a Uconnect Touchscreen Radio, all
enabling/disabling of air suspension features must be
done through the radio
page 170.
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.
