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 on the “UP” button, the highest flashing indicator
lamp is the position the system is working to achieve.
When lowering, if multiple indicators are flashing on the
DOWN button 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. engine running, speed below
threshold, etc). The “UP” button can be pushed 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 “DOWN” button once will move the suspen-
sion one position lower from the current level, assuming all
conditions are met (i.e. engine running, doors closed, speed
below threshold, etc). The “DOWN” button can be pressed
multiple times. Each push will lower the requested level by
one position down to a minimum of Park Mode or the
lowest position allowed based on current conditions (i.e.

STARTING AND OPERATING 283

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.
•Off-Road 2 (OR2) – Indicator lamps 4, 5, and 6 will be
illuminated when the vehicle is in OR2.
• Off-Road 1 (OR1) – Indicator lamps 4 and 5 will be
illuminated when the vehicle is in OR1.
• Normal Ride Height (NRH) – Indicator lamp 4 will be
illuminated when the vehicle is in this position.
• Entry/Exit Mode – Indicator lamp 3 will be illuminated
when the vehicle is in Entry/Exit Mode. If Entry/Exit
Mode is requested while vehicle speed is between 15
mph (24 km/h) and 25 mph (40 km/h), indicator lamp 4
will remain on solid and indicator lamp 3 will flash as
the system waits for the vehicle to reduce speed. If
vehicle speed is reduced to, and kept below, 15 mph
(24 km/h) indicator lamp 4 will turn off and indicator lamp 3 will flash until Entry/Exit Mode is achieved at
which point indicator lamp 3 will go solid. If during the
height change to Entry/Exit Mode, the vehicle speed
exceeds 15 mph (24 km/h), the height change will be
paused until the vehicle speed either goes below 15 mph
(24 km/h) and the height change continues to Entry/
Exit Mode, or exceeds 25 mph (40 km/h) and the vehicle
height will return to NRH. Entry/Exit Mode may be
selected while the vehicle is not moving provided that
the engine is still running and all doors remain closed.
• Transport Mode - No indicator lamps will be illumi-
nated. Customer driving will disable Transport Mode.
• Tire/Jack Mode - Indicator lamps 3 and 6 will be
illuminated. Customer driving will disable Tire/Jack
Mode.
• Wheel Alignment Mode - Indicator lamps 3 and 4 will be
illuminated. Customer driving will disable Wheel Align-
ment Mode.
284 STARTING AND OPERATING

FUEL SAVER TECHNOLOGY 5.7L ONLY — IF
EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine’s eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE: This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.

Alternate electric power steering efforts can be selected
through the Uconnect System. Refer to ”Customer Pro-
grammable Features” within “Uconnect Settings” in “Mul-
timedia” for further information.If the Electric Power Steering warning icon is
displayed and the “SERVICE POWER STEER-
ING” or the “POWER STEERING ASSIST OFF –
SERVICE SYSTEM” message is displayed within
the instrument cluster display, this indicates the vehicle
needs to be taken to the dealer for service. Refer to
“Warning Lights And Messages” in “Getting To Know
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.
If the Steering icon is displayed and the “POWER STEER-
ING SYSTEM OVER TEMP” message is displayed on the instrument cluster screen, they indicate that extreme steer-
ing 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.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce fuel con-
sumption. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal or pressing the accelerator pedal
will automatically re-start the engine.
This vehicle has been upgraded with a heavy duty starter,
enhanced battery, and other upgraded engine parts, to
handle the additional engine starts.
