Normal Ride Height (NRH) 0.0 inches (0 mm) –

This is the standard position of the suspension
and is meant for normal driving.
Aero Height (Lowers the vehicle approximately

-0.8 inches [-21 mm] Front and -1.0 inches
[-25 mm] Rear) – This position provides
improved aerodynamics by lowering the vehicle.
The vehicle will automatically enter Aero 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
NRH from Aero 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, regardless of vehicle
speed if the vehicle is in SPORT mode.
Entry/Exit Height (Lowers the vehicle approxi-

mately -1.8 inches [-46 mm] Front and
-2.0 inches [-50 mm] Rear) – 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, push the DOWN
button twice from NRH while the vehicle speed
is below 4 mph (6 km/h). To exit Entry/Exit,
push the UP button twice while in Entry/Exit or
drive the vehicle over 6 mph (10 km/h).
NOTE:
Automatic lowering of the vehicle into Entry/Exit
can be enabled through the Uconnect Touch-
screen 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 setting 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
Ú page 134.
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
STARTING AND OPERATING
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
Ú page 204.
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 Ú page 204.
