NOTE:The vehicle will automatically enter Aero Mode
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).
• Normal Ride Height (NRH) – This is the standard
position of the suspension and is meant for normal
driving.
• Off-Road 1 (OR1) (Raises the vehicle approximately
1 in (26 mm)) – This position should be the primary
position for all off-road driving until Off Road 2 (OR2) is
needed. A smoother and more comfortable ride will
result. To enter OR1, push the “Up” button once from
the NRH position while the vehicle speed is below
35 mph (56 km/h). When in the OR1 position, 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 automatically lowered to NRH. Off-Road 1 may
not be available due to vehicle payload, an instrument
cluster message will be displayed when this occurs.

in Entry/Exit or drive the vehicle over 15 mph
(24 km/h). Entry/Exit mode may not be available due to
vehicle payload, an instrument cluster message will be
displayed when this occurs. Refer to “Instrument Clus-
ter Display” in “Getting To Know Your Instrument
Panel” for further information.
NOTE: Entry/Exit mode may be achieved using your key
fob for easier entry/loading. Refer to “Keys” in “Getting To
Know Your Vehicle” for further information.
CAUTION!
When in ENTRY/EXIT setting, be aware of your sur-
roundings, you may not have the clearance required for
certain areas and vehicle damage may occur.
The system requires that the ignition be in ON/RUN
position or the engine running for all user requested
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 closed. This system uses a lifting and lowering pattern which
keeps the headlights from incorrectly shining into oncom-
ing 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 air suspension
system has a feature which allows the automatic leveling to
be disabled. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further
information.
NOTE:
If equipped with a touch screen radio all enabling/
disabling of air suspension features must be done through
the radio. Refer to “Uconnect Settings” in “Multimedia” for
further information.
WARNING!
The air suspension system uses a high pressure vol-
ume of air to operate the system. To avoid personal
