STARTING AND OPERATING

Quadra-Drive II System — If Equipped

The optional Quadra-Drive II System features two torque
transfer couplings. The couplings include an Electronic
Limited-Slip Differential (ELSD) rear axle and the Quadra-
Trac II transfer case. The optional ELSD axle is fully
automatic and requires no driver input to operate. Under
normal driving conditions, the unit functions as a standard
axle, balancing torque evenly between left and right
wheels. With a traction difference between left and right
wheels, the coupling will sense a speed difference. As one
wheel begins to spin faster than the other, torque will
automatically transfer from the wheel that has less traction,
to the wheel that has traction. While the transfer case and
axle coupling differ in design, their operation is similar.
Follow the Quadra-Trac II transfer case shifting informa-
tion, preceding this section, for shifting this system.

QUADRA-LIFT — IF EQUIPPED

Description

The Quadra-Lift air suspension system provides full time
load leveling capability along with the benefit of vehicle
height adjustment by the push of a button. The vehicle will
automatically raise and lower the ride height to adapt to
the appropriate driving conditions. At higher speeds, the

vehicle will lower to an aerodynamic ride height and when
operating in off-road modes, the vehicle will raise the ride
height accordingly. The buttons near the terrain switch in
the center console area can be used to set preferred ride
height to match the appropriate conditions.

STARTING AND OPERATING

279

• Normal Ride Height (NRH) – This is the standard

position of the suspension and is meant for normal
driving.

• Off-Road 1 (OR1) (Raises the vehicle approximately

1.1 inches (28 mm))

– This is the primary position for all

off-road driving until OR2 is needed. A smoother and
more comfortable ride will result. Push the “UP” button
once from the NRH position while the vehicle speed is
below 38 mph (61 km/h). When in the OR1 position, if
the vehicle speed remains between 40 mph (64 km/h)
and 50 mph (80 km/h) for greater than 20 seconds or if
the vehicle speed exceeds 50 mph (80 km/h), the vehicle
will be automatically lowered to NRH. Refer to “Driving
Tips” in “Starting And Operating” for further informa-
tion.

• Off-Road 2 (OR2) (Raises the vehicle approximately

2.2 inches (55 mm))

– This position is intended for

off-roading use only where maximum ground clearance
is required. To enter OR2, push the “UP” button twice
from the NRH position or once from the OR1 position
while vehicle speed is below 20 mph (32 km/h). While
in OR2, if the vehicle speed exceeds 25 mph (40 km/h)
the vehicle height will be automatically lowered to OR1.
Refer to “Driving Tips” in “Starting And Operating” for
further information.

• Aero Mode (Lowers the vehicle approximately

0.6 inches (15 mm))

– This position provides improved

aerodynamics by lowering the vehicle. The vehicle will
automatically enter Aero Mode when the vehicle speed
remains between 52 mph (83 km/h) and 56 mph
(90 km/h) for greater than 20 seconds or if the vehicle
speed exceeds 56 mph (90 km/h). The vehicle will return
to NRH from Aero Mode if the vehicle speed remains
between 20 mph (32 km/h) and 25 mph (40 km/h) for
greater than 20 seconds or if the vehicle speed falls
below 20 mph (32 km/h). The vehicle will enter Aero
Mode, regardless of vehicle speed if the vehicle is in
“SPORT” mode.

• Entry/Exit Mode (Lowers the vehicle approximately

1.6 inches (40 mm)

– This position lowers the vehicle for

easier passenger entry and exit as well as lowering the
rear of the vehicle for easier loading and unloading of
cargo. To enter Entry/Exit Mode, push the “DOWN”
button once from (NRH) while the vehicle speed is
below 25 mph (40 km/h). Once the vehicle speed goes
below 15 mph (24 km/h) the vehicle height will begin to
lower. If the vehicle speed remains between 15 mph
(24 km/h) and 25 mph (40 km/h) for greater than 60
seconds, or the vehicle speed exceeds 25 mph (40 km/h)
the Entry/Exit Mode change will be cancelled. To exit

280

STARTING AND OPERATING

Entry/Exit Mode, press the “Up” button once while in
Entry/Exit Mode or drive the vehicle over 15 mph
(24 km/h).

NOTE:

Automatic lowering of the vehicle into Entry/Exit

Mode can be enabled through the Uconnect Touch-Screen
Radio. If this feature is enabled, the vehicle will only lower
if the gear selector is in

⬙PARK⬙, the terrain switch is in

⬙AUTO⬙, the transfer-case is in ⬙AUTO” and the vehicle
level should be either in Normal or Aero Mode. The Vehicle
will not automatically lower if the air suspension level is in
Off Rd 2 or Off Rd 1. If the vehicle is equipped with
Intrusion Theft Module (ITM), the lowering will be sup-
pressed when the ignition is switched OFF and the door is
open to prevent setting the alarm off.

The Selec-Terrain switch will automatically change the
vehicle to the proper height based on the position of the
Selec-Terrain switch. The height can be changed from the
default Selec-Terrain setting by normal use of the air
suspension buttons. Refer to “Selec-Terrain” in “Starting
And Operating” for further information.

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/are closed.

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”

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.

STARTING AND OPERATING

SELEC-TERRAIN — IF EQUIPPED

Selec-Terrain Mode Selection

Selec-Terrain combines the capabilities of the vehicle con-
trol systems, along with driver input, to provide the best
performance for all terrains.

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.
