to Normal Height Mode, push the height
selector switch up once while 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
Úpage 114.
NOTE:
Entry/Exit mode may be achieved using your
key fob for easier entry/loading Ú page 17.
The system requires that the ignition be in the
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 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 air
suspension system has a feature which allows
the automatic leveling to be disabled
Ú
page 114.
NOTE:
If equipped with a touchscreen radio, all
enabling/disabling of air suspension features
must be done through the radio Ú page 237.AIR SUSPENSION MODES
The air suspension system has multiple modes
to protect the system in unique situations. The
engine should be running to change between
Air Suspension Modes.
Automatic AERO Mode
To improve aerodynamics, the air suspension
system has a feature which will put the vehicle
into AERO height automatically Úpage 114.
Automatic Aero Mode may be disabled through
vehicle settings in the Uconnect Radio (if
equipped) Ú page 237.
Tire Jack Mode
To assist with changing a tire, the air
suspension system has a feature which allows
the automatic leveling to be disabled
Ú page 237.
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
Ú page 237.
CAUTION!
When in ENTRY/EXIT setting, be aware of your
surroundings, you may not have the
clearance required for certain areas and
vehicle damage may occur.
WARNING!
The air suspension system uses a high
pressure volume of air to operate the system.
To avoid personal injury or damage to the
system, see an authorized dealer for service.

Protection Strategy
In order to “protect” the air suspension system,
the vehicle will disable load leveling as required
(suspension overloaded, battery charge low,
etc.). Load leveling will automatically resume as
soon as system operation requirements are
met. See an authorized dealer if system does
not resume.

OPERATION

Air Suspension Switch

The indicator lamps 1 through 5 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 height selector up 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 height selector switch can be pushed up
multiple times, each push will raise the
requested 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 height selector down once will
move the suspension 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 height selector switch can be pushed
down 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.)
Automatic height changes will occur based on
vehicle speed and the current vehicle height.
The indicator lamps and instrument cluster
display messages will operate the same for
automatic changes and user requested
changes.

Press OK to Switch to Parallel Park

NOTE:
When searching for a parking space, use the
turn signal indicator to select which side of
the vehicle you want to perform the parking
maneuver. The ParkSense Active Park Assist system will automatically search for a parking
space on the passenger's side of the vehicle
if the turn signal is not activated.
The driver needs to make sure that the
selected parking space for the maneuver
remains free and clear of any obstructions
(e.g. pedestrians, bicycles, etc.).
The driver is responsible to ensure that the
selected parking space is suitable for the
maneuver and free/clear of anything that
may be overhanging or protruding into the
parking space (e.g., ladders, tailgates, etc.
from surrounding objects/vehicles).
When searching for a parking space, the
driver should drive as parallel or perpendic
-
ular (depending on the type of maneuver) to
other vehicles as possible.
The feature will only indicate the last
detected parking space (example: if passing
multiple available parking spaces, the
system will only indicate the last detected
parking space for the maneuver). A parking
space is considered invalid after the vehicle
is 32 ft (10 m) or more away from it.

Left Lane Departure — Both Lane Lines
Detected
When the LaneSense system is on and both
the lane markings have been detected, the
system is "armed" to provide visual warnings
in the instrument cluster display and a torque
warning in the steering wheel if an uninten -
tional lane departure occurs .The lane lines
turn from gray to white and the LaneSense
telltale is solid green.

Lanes Sensed (White Lines) With Green Telltale

When the LaneSense system senses a lane
drift situation, the left lane line turns solid
yellow. The LaneSense telltale changes
from solid green to solid yellow. At this time
torque is applied to the steering wheel in the
opposite direction of the lane boundary. For example: If approaching the left side of
the lane the steering wheel will turn to the
right.

Lane Sensed (Solid Yellow Lane Line) With Solid Yellow Telltale

When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the left lane line flashes yellow
(on/off). The LaneSense telltale changes
from solid yellow to flashing yellow. At this
time torque is applied to the steering wheel in
the opposite direction of the lane boundary. For example: If approaching the left side of
the lane the steering wheel will turn to the
right.

Lane Approached (Flashing Yellow Lane Line) With Flashing Yellow Telltale

NOTE:
The LaneSense system operates with similar
behavior for a right lane departure.
