NOTE:
Vehicles equipped with Quadra-Lift must be placed in Transport Mode before tying
them down (from the body) on a trailer or flatbed truck. If the vehicle cannot be
placed in Transport mode (for example, engine will not run), tie-downs must be
fastened to the axles (not to the body). Failure to follow these instructions may cause
fault codes to be set and/or cause loss of proper tie-down tension.
Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain will result.
Recreational towing (for two-wheel drive models) is allowed ONLY if the rear wheels
are OFF the ground. This may be accomplished using a tow dolly or vehicle trailer. If
using a tow dolly, follow this procedure:
1. Properly secure the dolly to the tow vehicle, following the dolly manufacturer's
instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Shift the transmission into PARK.
4. Turn the ignition switch to the OFF position.

5. Properly secure the rear wheels to the dolly, following the dolly manufacturer’sinstructions.
6. Install a suitable clamping device, designed for towing, to secure the front wheels in the straight position.
CAUTION!
Towing with the rear wheels on the ground will cause severe transmission damage.
Damage from improper towing is not covered under the New Vehicle Limited
Warranty.
Four-Wheel Drive Models Without 4WD LOW Range
Recreational towing is not allowed. These models do not have a NEUTRAL (N)
position in the transfer case.
Four-Wheel Drive Models With 4WD LOW Range
The transfer case must be shifted into NEUTRAL (N) and the transmission must be
in PARK for recreational towing. The NEUTRAL (N) selection button is adjacent to
the transfer case selector switch. Shifts into and out of transfer case NEUTRAL (N)
can take place with the selector switch in any mode position.
CAUTION!
• DO NOT dolly tow any 4WD vehicle. Internal damage to the transmission or transfer case will occur if a dolly is used when recreational towing.
• Tow only in a forward direction. Towing this vehicle backwards can cause severe
damage to the transfer case.
• The transmission must be in PARK for recreational towing.
• Before recreational towing, perform the procedure outlined under “Shifting
into NEUTRAL (N)” to be certain that the transfer case is fully in NEUTRAL
(N). Otherwise, internal damage will result.
• Failure to follow these procedures can cause severe transmission and/or
transfer case damage. Damage from improper towing is not covered under the
New Vehicle Limited Warranty.
• Do not use a bumper-mounted clamp-on tow bar on your vehicle. The bumper
face bar will be damaged.

Shifting Into NEUTRAL (N)
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.
Use the following procedure to prepare your vehicle for recreational towing:
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 Driver
Information Display (DID).
6. After the shift is completed and the NEUTRAL (N) light stays on, release the NEUTRAL (N) button.
7. Shift the transmission into REVERSE.
8. Release the brake pedal for five seconds and ensure that there is no vehicle movement.
9. Press and hold the brake pedal. Shift the transmission back into NEUTRAL
10. Firmly apply the parking brake.
11. With the transmission and transfer case in NEUTRAL, push and hold the ENGINE START/STOP button until the engine turns off.
12. Move the transmission gear selector to PARK. Release the brake pedal.

SELEC-TRACK
Selec-Track combines the capabilities of
the vehicle control systems, along with
driver input, to provide the best perfor-
mance for all terrains.
Rotate the mode control knob to select
the following Selec-Track positions:
•Sport - Dry weather, on-road calibra-
tion. Performance based tuning that
provides a rear wheel drive feel but with improved handling and acceleration over
a two-wheel drive vehicle. The active suspension system will be in a semi firm
mode, and a green flag will light up in the instrument cluster.
• Snow - Tuning set for additional stability in inclement weather. Use on and off road
on loose traction surfaces such as snow.
• Auto - Fully automatic full time four-wheel drive operation can be used on and off
road. This position balances traction with seamless steering feel to provide
improved handling and acceleration over two-wheel drive vehicles.
• Track - This position offers track road calibration for use on high traction surfaces.
Driveline is maximized for traction. Some binding may be felt on less forgiving
surfaces.
• To w - Use this mode for towing. Vehicle suspension will go to Firm mode.
Active Damping System
This vehicle is equipped with an electronic controlled damping system. This system
reduces body roll and pitch in many driving situations including cornering, accelera-
tion and braking. There are 3 modes:
•Street Mode (Available in terrain positions AUTO, SNOW and CUSTOM.) — Used
during highway speeds where a touring suspension feel is desired.
• Sport Mode (Available in terrain positions AUTO, SPORT, CUSTOM and TOW.) —
Provides a firm suspension for better handling.
• Track Firm (Available in terrain positions AUTO, TRACK and CUSTOM.) —
Provides a full firm suspension for an aggressive track experience.

Launch Mode — If Equipped
This system maximizes acceleration traction for straight line racing. To use Launch
Mode please follow the steps below:
1. Bring vehicle to complete stop on a level track surface with the engine running.
2. Set the steering wheel for straight ahead driving.
3. Fully press the brake pedal.
4. Press and release the “LAUNCH” Button.
5. Press the accelerator pedal to the floor.
NOTE:
If the cluster launch DID message indicates all conditions are correct for launch and
the throttle is pressed to the floor quickly (within approximately 1/2 second) the
system will hold the engine speed to a preset speed (below the engine rev limiter
speed).
6. Release the brake pedal.
Pressing the launch control button when launch control is active will deactivate
launch control.
NOTE:
• Launch Mode brings the engine to optimum RPM and waits for the driver torelease the brake. Launch Mode then uses engine throttle only to achieve
controlled wheelslip for maximum acceleration through 62 mph (100 km/h).
• Launch Mode can be initiated in any of the Select Trac Modes.
• Launch Mode is not available until the 500 mile (805 km) break-in has been achieved.

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute and then remain continuously
illuminated. This sequence will continue each time the vehicle is restarted as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C) and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermar-
ket wheels can cause sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a TPMS, as damage to the sensors
may result.
– Seat Belt Reminder Light
When the ignition switch is first turned to the ON/RUN position, this light will turn on
for four to eight seconds as a bulb check. During the bulb check, if the driver's seat
belt is unbuckled, a chime will sound. After the bulb check or when driving, if the
driver or front passenger seat belt remains unbuckled, the Seat Belt Indicator Light
will flash or remain on continuously. Refer to “Seat Belt Systems” in “Things To
Know Before Starting” in your Owner’s Manual on the DVD for further information.

JACKING AND TIRE CHANGING
WARNING!
• Do not attempt to change a tire on the side of the vehicle close to movingtraffic. Pull far enough off the road to avoid the danger of being hit when
operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the
jack and fall on you. You could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get under a raised vehicle, take
it to a service center where it can be raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack
should not be used to lift the vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or slippery areas.
Run Flat Tires — SRT Models
This vehicle is equipped with “run flat” tires. Run flat tires allow the vehicle to be
driven approximately 50 miles (80km) at 55 mph (88km/h). Tire service should be
obtained to avoid prolonged run flat feature usage.
WARNING!
Do not exceed 50 mph (80 km/h) if the “Tire Pressure Monitoring Telltale Light”
is illuminated. Vehicle handling and braking may be reduced. You could have a
collision and be severely or fatally injured.
