seconds, or the vehicle speed exceeds 25 mph
(40 km/h) the Entry/Exit change will be cancelled. To
return to Normal Height Mode, press the “Up” button
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 EVIC/DID mes-
sage will be displayed when this occurs. Refer to
“Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID)” 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.
•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 on-
coming 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 “Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID)” in
“Understanding Your Instrument Panel” for further in-
formation.
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 in-
formation.
WARNING!
The air suspension system uses a high pressure
volume of air to operate the system. To avoid per-
sonal 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:

cannot be achieved. Some driving may be required to
clear the protection mode telltale in the EVIC/DID. Refer
to “Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID)” in “Understanding
Your Instrument Panel” or “Uconnect® Settings” in “Un-

STARTING AND OPERATING 527
If the Steering icon is flashing, it indicates that the vehicle
needs to be taken to the dealer for service. It is likely the
vehicle has lost power steering assistance.
If the Steering icon is displayed and the “POWER STEER-
ING SYSTEM OVER TEMP” message is displayed on the
EVIC/DID screen, they indicate that extreme steering
maneuvers may have occurred which caused an over
temperature condition in the power steering system.
Once driving conditions are safe, pull over and let the
vehicle idle for a few moments until the icon and
message turn off. Refer to “Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID)” in
“Understanding Your Instrument Panel” for further in-
formation.
If the Steering icon is displayed and the “SERVICE
POWER STEERING – ASSIST OFF” message is displayed
the EVIC/DID screen, they indicate the vehicle needs to
be taken to the dealer for service. Refer to “Electronic
Vehicle Information Center (EVIC) or Driver Information
Display (DID)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
•Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substantial
increase in steering effort, especially at low speeds and
during parking maneuvers.
•If the condition persists, see your authorized dealer for
service.
POWER STEERING — 2500/3500 MODELS
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.

WARNING!(Continued)
•HSA is not a parking brake. If you stop the vehicle
on a hill without putting the transmission in PARK
or using the parking brake, it will roll down the
incline and could collide with another vehicle,
object or person, and cause serious or fatal injury.
Always remember to use the parking brake while
parking on a hill and that the driver is responsible
for braking the vehicle.
HSA Off
HSA is a Customer Programmable Feature in the EVIC/
DID. If you wish to turn off the HSA feature, refer to
“Electronic Vehicle Information Center (EVIC)/Driver
Information Display (DID)” in “Understanding Your
Instrument Panel” for further information.
Electronic Stability Control (ESC)
The ESC system enhances directional control and stabil-
ity of the vehicle under various driving conditions. ESC
corrects for oversteering or understeering of the vehicle
by applying the brake of the appropriate wheel to assist
in counteracting the oversteer or understeer condition.
Engine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
