The system requires that the engine be running for all
changes. When lowering the vehicle all of the doors,
including the liftgate, 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.
290 STARTING AND OPERATING

The Quadra-Lift air suspension system uses a lifting and
lowering pattern which keeps the headlights from incor-
rectly 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 Quadra-Lift air
suspension system has a feature which allows the auto-
matic leveling to be disabled. Refer to “Uconnect Settings”
in “Multimedia” for further information.

Panel” for further information.
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
Up
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.
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.
292 STARTING AND OPERATING

•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

STARTING AND OPERATING 293

Selec-Terrain consists of the following positions:
•Snow – Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as snow. When in Snow mode (depending on
certain operating conditions), the transmission may use
second gear (rather than first gear) during launches, to
minimize wheel slippage. If equipped with air suspen-
sion, the default ride height for Snow is Normal Ride
Height (NRH).
• Auto – Fully automatic full time four-wheel drive op-
eration can be used on and off road. Balances traction with seamless steering feel to provide improved han-
dling and acceleration over two-wheel drive vehicles. If
equipped with air suspension, the level will change to
Normal Ride Height (NRH).
• Sand – Off road calibration for use on low traction
surfaces such as sand or wet grass. Driveline is maxi-
mized for traction. Some binding may be felt on less
forgiving surfaces. The electronic brake controls are set
to limit traction control management of throttle and
wheel spin. If equipped with air suspension, the default
ride height for Sand is Normal Ride Height (NRH).
• Mud – Off road calibration for use on low traction
surfaces such as mud. Driveline is maximized for trac-
tion. Some binding may be felt on less forgiving sur-
faces. The electronic brake controls are set to limit
traction control management of throttle and wheel spin.
If equipped with air suspension, the level will change to
Off Road 1.
• Rock – Off road calibration only available in 4WD Low
range. The vehicle is raised (if equipped with Air
Suspension) for improved ground clearance. Traction
based tuning with improved steer-ability for use on high
traction off-road surfaces. Use for low speed obstacles
such as large rocks, deep ruts, etc. If equipped with air

FUEL SAVER TECHNOLOGY 5.7L ENGINE 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.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
