to be disabled. Refer to “Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:This mode is intended to be enabled with engine
running.
Transport Mode
To assist with flat bed towing, 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 “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for further
information.
NOTE: This mode is intended to be enabled with engine
running. Wheel Alignment Mode
Before performing a wheel alignment this mode must be
enabled. Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
further information.
NOTE:
This mode is intended to be enabled with engine
running.
Protection Mode
In order to “protect” the air suspension system, the
vehicle will enter Protection Mode when load leveling
cannot be achieved. Some driving may be required to
clear the protection mode telltale in the EVIC. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.

NOTE:If equipped with a touch screen radio all
enabling/disabling of air suspension features must be
done through the radio. Refer to “Uconnect® Access
Settings” in “Understanding Your Instrument Panel” for
further information.
Electronic Vehicle Information Center (EVIC)
Display Messages
When the appropriate conditions exist, a message will
appear in the EVIC display. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
An audible chime will be heard whenever a system error
has been detected.
Operation
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 posi-
tion the system is working to achieve. When lowering, if
multiple indicators are flashing, the lowest solid indica-
tor lamp is the position the system is working to achieve.
Pressing 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 pressed multiple times, each press will
raise the requested level by one position up to a maxi-
mum position of OR2 or the highest position allowed
based on current conditions (i.e. vehicle speed, etc).
Pressing the “DOWN” button once will move the sus-
pension one position lower from the current level, as-
suming all conditions are met (i.e. key in ON/RUN
position, engine running, doors closed, speed below
threshold, etc). The “DOWN” button can be pressed
multiple times, each press will lower the requested level

Electronic Speed Control – If Equipped
•Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed. Air Conditioning
Turn off temporarily.
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air
Suspension System” in “Starting and Operating” for
further information.
NOTE:
The vehicle must remain in the engine running
position while attaching a trailer for proper leveling of
the air suspension system.
SNOWPLOW
1500 Models Only
NOTE: Do not use this model vehicle for snowplow
applications.

STARTING AND OPERATING 561
Page 569 of 743

NOTE:Vehicles equipped with air suspension must be
lowered to the “Entry/Exit” (lowest) level, and have
automatic leveling disabled, before tying them down
(from the body) on a trailer or flatbed truck. Refer to “Air
Suspension – If Equipped” for more information. If the
vehicle cannot be lowered to the “Entry/Exit” level (for
example, engine will not run), tie-downs must be fas-
tened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
Recreational Towing – Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is
allowed ONLYif the rear wheels are OFFthe ground.
This may be accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this procedure: 1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place automatic trans- mission in PARK, manual transmission in gear (not in
NEUTRAL).
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer’s instructions.
5. Turn the ignition switch to the OFF position and remove the key fob.
6. Install a suitable clamping device, designed for tow- ing, to secure the front wheels in the straight position.

WARNING!(Continued)
•Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.
• Never start or run the engine while the vehicle is
on a jack.
• The jack is designed to be used as a tool for
changing tires only. The jack should not be used to
lift the vehicle for service purposes. The vehicle
should be jacked on a firm level surface only.
Avoid ice or slippery areas. NOTE:
To assist with changing a spare tire, the air
suspension system has a feature which allows the auto-
matic leveling to be disabled. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
Jack Location
The jack and jack tools are stored under the front
passenger seat.
Removal Of Jack And Tools (1500 Series)
To access the jack and jack tools you must remove the
plastic access cover, located on the side of the front
passengers seat. To remove the cover, pull the front part
of the cover (closest to the front of the seat) toward you
to release a locking tab. Once the front of the cover is
loose, slide the cover toward the front of the seat until it
is free from the seat frame.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial wrecker service. If the trans-
mission and drivetrain are operable, disabled vehicles
may also be towed as described under “Recreational
Towing” in the “Starting and Operating” section.NOTE:
Vehicles equipped with air suspension must be
lowered to the Park (lowest) level, and have automatic
leveling disabled, before tying them down (from the
body) on a trailer or flatbed truck. Refer to Air Suspen-
sion inStarting and Operating for more information. If
the vehicle cannot be lowered to the Park level (for
example, engine will not run), tie-downs must be fas-
tened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
