2 — Down Button
3 — Entry/Exit Mode Indicator (Customer selectable)
4 — Normal Ride Height Indicator (Customer selectable)
5 — Off-Road 1 Indicator (Customer selectable)
6 — Off-Road 2 Indicator (Customer selectable)
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.
Refer to “Instrument Cluster Display” in “Understand-
ing Your Instrument Panel” for further information.

once while in Entry/Exit or drive the vehicle over
15 mph (24 km/h). Entry/Exit mode may not be avail-
able due to vehicle payload, an instrument cluster
message will be displayed when this occurs. Refer to
“Instrument Cluster Display” in “Understanding Your
Instrument Panel” for further information.
NOTE: Entry/Exit mode may be achieved using your key
fob for easier entry/loading. Refer to “A Word About Your
Keys” in “Things To Know Before Starting 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
“Understanding Your Instrument Panel” for further infor-
mation.
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 “Understanding
Your Instrument Panel” for further information.

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 your authorized
dealer for service.
Air Suspension Modes
The Air Suspension system has multiple modes to protect
the system in unique situations:
AERO Mode
To improve aerodynamics, the air suspension system has a
feature which will put the vehicle into AERO height
automatically. Refer to “Instrument Cluster Display” in
“Understanding Your Instrument Panel” for further infor-
mation.
NOTE:This mode is intended to be enabled with engine
running. Tire/Jack Mode
To assist with changing a tire, the air suspension system
has a feature which allows the automatic leveling to be
disabled. Refer to “Instrument Cluster Display” in “Under-
standing Your Instrument Panel” or “Uconnect Settings” in
“Understanding Your Instrument Panel” if equipped with
a touch screen radio for further information.
NOTE:
This mode is intended to be enabled with engine
running.
Transport Mode
For towing your vehicle with four wheels off the road, the
air suspension system has a feature which will put the
vehicle into Entry/Exit height and disable the automatic
load leveling system. Refer to “Instrument Cluster Dis-
play” in “Understanding Your Instrument Panel” or

enabled. Refer to “Instrument Cluster Display” in “Under-
standing Your Instrument Panel” or “Uconnect Settings” in
“Understanding Your Instrument Panel” if equipped with

Protection Strategy
In order to “protect” the air suspension system, the vehicle
will disable load leveling as required (suspension over-
loaded, battery charge low, etc.). Load leveling will auto-
matically resume as soon as system operation requirements
are met. See your authorized dealer if system does not
resume.
NOTE: If towing with air suspension refer to “Trailer
Towing” in “Starting And Operating” for further informa-
tion.Instrument Cluster Display Messages
When the appropriate conditions exist, a message will
appear in the instrument cluster display. Refer to “Instru-
ment Cluster Display” in “Understanding Your Instrument
Panel” for further information.
An audible chime will be heard whenever a system error
has been detected.
See your authorized dealer for system service if normal
operation does not resume.

4 — Normal Ride Height Indicator (Customer selectable)
5 — Off-Road 1 Indicator (Customer selectable)
6 — Off-Road 2 Indicator (Customer selectable)
The indicator lamps 3 through 6 will illuminate to show the
current position of the vehicle. Flashing indicator lamps
will show a position which the system is working to
achieve. When raising, if multiple indicator lamps are
flashing, the highest flashing indicator lamp is the position
the system is working to achieve. When lowering, if
multiple indicators are flashing, the lowest solid indicator
lamp is the position the system is working to achieve.
Pushing the “Up” button once will move the suspension
one position higher from the current position, assuming all
conditions are met (i.e. key in ON/RUN position, engine
running, speed below threshold, etc). The “Up” button can
be pushed multiple times, each push will raise the re-
quested level by one position up to a maximum position of
OR2 or the highest position allowed based on current
conditions (i.e. vehicle speed, etc).
Pushing the “DOWN” button once will move the suspen-
sion one position lower from the current level, assuming all
conditions are met (i.e. key in ON/RUN position, engine
running, doors closed, speed below threshold, etc). The
“DOWN” button can be pushed multiple times, each push
will lower the requested level by one position down to a
minimum of Entry/Exit Mode or the lowest position
allowed based on current conditions (i.e. vehicle speed,
etc.)
