PADDLE SHIFT MODE
Paddle Shift Mode is a driver-interactive transmission feature that offers manual gear
shifting to provide you with more control of the vehicle. Paddle Shift Mode allows you
to maximize engine braking, eliminate undesirable upshifts and downshifts, and
improve overall vehicle performance.
This system can also provide you with more control during passing, city driving, cold
slippery conditions, mountain driving, trailer towing, and many other situations.
Refer to the “Starting And Operating” section of your vehicle’s Owner’s Manual on
the DVD for further details.
FUEL ECONOMY (ECO) MODE
The Fuel Economy (ECO) mode can improve the vehicle’s overall fuel economy during
normal driving conditions.
• Press the “ECO” switch in the center
stack of the instrument panel and a
amber light will indicate the ECO mode
is engaged.
When the Fuel Economy (ECO) Mode is
engaged, the vehicle control systems will
be able to change the following:
• The transmission will upshift sooner
and downshift later.
• The overall driving performance will
be more conservative.
• Some ECO mode functions may be
temporarily inhibited based on tem-
perature and other factors.
NOTE:
When Sport Mode is enabled, the vehicle’s air suspension system will operate in
“Aero” Mode. Please refer to “QUADRA-LIFT™” within “OFF-ROAD CAPABILITIES”
for further information.

Shifting Procedures
4WD HI To 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the
ON/RUN position or the engine running, shift the transmission into NEUTRAL and
press the “4WD LOW” button once on the transfer case switch. The “4WD LOW”
indicator light in the instrument cluster will begin to flash and remain on solid when
the shift is complete.
4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the
ON/RUN position or the engine running, shift the transmission into NEUTRAL, and
press the “4WD LOW” button once on the transfer case switch. The “4WD LOW”
indicator light in the instrument cluster will flash and turn off when the shift is
complete.
NOTE:
• If the shift conditions/interlocks are not met, or a transfer case motor temperature
protection exists, a “For 4x4 Low Slow Below 5 mph (8 km/h) Put Trans in N Press
4 Low” message will flash on the Electronic Vehicle Information Center (EVIC).
• Shifting into or out of 4WD LOW is possible with the vehicle completely stopped;
however, difficulty may occur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch teeth alignment and shift
completion to occur. The preferred method is with the vehicle rolling 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster than 3 mph (5 km/h), the transfer case
will not allow the shift.
NEUTRAL Shift Procedure
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.
4. If vehicle is equipped with Quadra-Lift™ air suspension, ensure the vehicle is set
to Normal Ride Height.
5. Using a ballpoint pen or similar object, press and hold the recessed transfer case
NEUTRAL (N) button (located by the selector switch) for four seconds. The light
behind the N symbol will blink, indicating shift in progress. The light will stop
blinking (stay on solid) when the shift to NEUTRAL (N) is complete. A “FOUR
WHEEL DRIVE SYSTEM IN NEUTRAL” message will display on the EVIC
(Electronic Vehicle Information Center).
6. After the shift is completed and the NEUTRAL (N) light stays on, release the
NEUTRAL (N) button.

SELEC-TERRAIN™
Selec-Terrain™ combines the capabilities of the vehicle control systems, along with
driver input, to provide the best performance for all terrains.
Rotate the mode control knob to select the following Selec-Terrain™ 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 suspension, the
level will change to Normal Ride Height (NRH) if the transfer case is in high range.
The level will change to Off-Road 1 if the transfer case is in Low range.
Auto– Fully automatic full time four-wheel drive operation can be used on and off
road. Balances traction with seamless steering feel to provide improved handling and
acceleration over two-wheel drive vehicles. If equipped with air suspension, the level
will change to NRH.
Sand– Off road calibration for use on low traction surfaces such as sand or wet grass.
Driveline is maximized 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 level will change to
Off-Road 1.
Mud– Off road calibration for use on low traction surfaces such as mud. Driveline is
maximized 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 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. Activate the Hill Descent
Control for steep downhill control. Use for low speed obstacles such as large rocks, deep
ruts, etc. If equipped with air suspension, the vehicle level will change to Off-Road 2.
If the Selec-Terrain™ switch is in ROCK mode, and the transfer case is switched from 4WD
Low to 4WD High, the Selec-Terrain™ system will return to AUTO.

QUADRA-LIFT™
The Quadra-Lift™ air suspension system provides full time load leveling capability
along with the benefit of being able to adjust vehicle height by the push of a button.
Quadra-Lift™ is available with both Quadra-Trac II
®and Quadra-Drive II™.
• 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.
• The Quadra-Lift™ air suspension sys-
tem uses a lifting and lowering pattern
which keeps the headlights from shin-
ing 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, you may
notice that the air suspension system
operates briefly. This is normal. The
system is correcting the position of the vehicle.
• To assist with changing a spare tire, the Quadra-Lift™ air suspension system has
a feature which allows the automatic leveling to be disabled. The feature controls
are located in the radio screen. Driving the vehicle over 5 mph (8 km/h) will return
the air suspension to normal operation.
• An audible chime will be heard whenever a system error has been detected.
Operation
• Pressing the “Up” or “Down” button once will move the suspension one position
higher or lower from the current position, assuming all conditions are met (i.e.,
engine running and all doors and liftgate closed).
• The 4 indicator lamps will illuminate to show the current position of the vehicle.
Flashing indicator lamps will show a position which the system is working to
achieve. If multiple indicator lamps are flashing on the “Up” button, the highest
flashing indicator lamp is the position the system is working to achieve.
• Normal Ride Height (NRH) – This is the standard position of the
suspension and is meant for normal driving. Only the bottom Indicator
lamp on the “Up” button will be illuminated when the vehicle is in this
position.

•Off-Road 1 (OR1) (Raises the vehicle approximately 1.28 in (32.5 mm)
– This is the primary position for all off-road driving until OR2 is needed.
A smoother and more comfortable ride will result. Press 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.
•Off-Road 2 (OR2) (Raises the vehicle approximately 2.6 in (65 mm) –
This position is intended for off-roading use only where maximum
ground clearance is required. To enter OR2, press 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.
• Entry/Exit Mode (Lowers the vehicle approximately 1.5 in (38 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, press 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
Entry/Exit Mode, press the “Up” button once while in Entry/Exit Mode or drive the
vehicle over 15 mph (24 km/h).
• Aero Mode (Lowers the vehicle approximately 0.6 in (15 mm) – This position
provides improved aerodynamics by lowering the vehicle. The vehicle will auto-
matically enter Aero Mode when the vehicle speed remains between 99 km/h
(62 mph) and 106 km/h (66 mph) for greater than 20 seconds or if the vehicle
speed exceeds 106 km/h (66 mph). The vehicle will return to NRH from Aero Mode
if the vehicle speed remains between 48 km/h (30 mph) and 56 km/h (35 mph)
for greater than 20 seconds or if the vehicle speed falls below 48 km/h (30 mph).
The vehicle will enter Aero Mode, regardless of vehicle speed if the shift lever is in
the “SPORT” position.
NOTE:
When ECO Mode is enabled the air suspension system lowers the vehicle to Aero
mode when the vehicle speed is between 52 mph (84 km/h) and 56 mph (90 km/h)
for 20 seconds or goes above 56 mph (90 km/h). The vehicle will exit Aero mode if
the vehicle speed remains between 20 mph (32 km/h) and 25 mph (40 km/h) for
20 seconds or if the vehicle speed falls below 20 mph (32 km/h).

WARNING!
• You or others could be injured if you leave the vehicle unattended with the
transfer case in the N (Neutral) position without first fully engaging the parking
brake. The transfer case N (Neutral) position disengages both the front and rear
driveshafts from the powertrain and will allow the vehicle to move regardless of
the transmission position. The parking brake should always be applied when
the driver is not in the vehicle.
• The air suspension system uses a high pressure volume of air to operate the
system. To avoid personal injury or damage to the system, see your authorized
dealer for service.
HILL START ASSIST/HILL DESCENT CONTROL/SELEC
SPEED CONTROL
• The Hill Start Assist system assists the driver when starting a vehicle from a stop
on a hill.
• The Hill Descent Control system maintains vehicle speed while descending hills
during off-road driving situations and is available in 4WD HIGH range and 4WD
LOW range.
• The Selec Speed Control feature allows the driver to travel at slow speeds on level
ground, uphill or downhill without actively controlling either the throttle or brake.
• Refer to your Owner's Manual on the DVD for further details.

12. Firmly apply the parking brake.
13. Attach the vehicle to the tow vehicle using a suitable tow bar.
14. Release the parking brake.
NOTE:
• Steps 1 through 4 are requirements that must be met before pressing the
NEUTRAL (N) button, and must continue to be met until the shift has been
completed. If any of these requirements are not met before pressing the NEUTRAL
(N) button or are no longer met during the shift, then the NEUTRAL (N) indicator
light will flash continuously until all requirements are met or until the NEUTRAL
(N) button is released.
• The ignition switch must be in the ON/RUN position for a shift to take place and
for the position indicator lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no position indicator lights will
be on or flashing.
• A flashing NEUTRAL (N) position indicator light indicates that shift requirements
have not been met.
• If the vehicle is equipped with Quadra-Lift™ air suspension, the engine should be
started and left running for a minimum of 60 seconds (with all the doors closed)
at least once every 24 hours. This process allows the air suspension to adjust the
vehicle’s ride height to compensate for temperature effects.
WARNING!
You or others could be injured or killed if you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position without first fully engaging the parking
brake. The transfer case NEUTRAL (N) position disengages both the front and rear
driveshafts from the powertrain and will allow the vehicle to move, even if the
transmission is in PARK. The parking brake should always be applied when the
driver is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain that the transfer case is fully in
NEUTRAL (N) before recreational towing to prevent damage to internal parts.
