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.

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.
Paddle Shift Mode Operation
When the shift lever is in the DRIVE position, the transmission will operate
automatically, shifting between the five available gears. To engage Paddle Shift
Mode, simply tap the shift lever to the right or left (+/-) while in the DRIVE position,
or tap one of the steering wheel-mounted shift paddles (+/-). Tapping (-) to enter
Paddle Shift Mode will downshift the transmission to the next lower gear, while using
(+) to enter Paddle Shift Mode will retain the current gear.
When Paddle Shift mode is active, the current transmission gear is displayed in the
instrument cluster. In Paddle Shift Mode, the transmission will shift up or down when
(+/-) is manually selected by the driver (using the shift lever, or the shift paddles),
unless an engine lugging or overspeed condition would result. It will remain in the
selected gear until another upshift or downshift is chosen, except as described
below:
• Normally, in Paddle Shift Mode, the transmission will automatically shift up when
maximum engine speed is reached. If, however, Paddle Shift Mode is engaged
while in SPORT mode, the transmission will remain in the selected gear even when
maximum engine speed is reached. The transmission will upshift only when
commanded by the driver.
• The transmission will automatically downshift as the vehicle slows (to prevent
engine lugging) and will display the current gear.
• The transmission will automatically downshift to first gear when coming to a stop.
After a stop, the driver should manually upshift (+) the transmission as the vehicle
is accelerated.
• You can start out in first or second gear. Tapping (+) (at a stop) will allow starting
in second gear. Starting out in second gear is helpful in snowy or icy conditions.
• If a requested downshift would cause the engine to over-speed, that shift will not
occur.
• The system will ignore attempts to upshift at too low of a vehicle speed.

• Avoid using speed control when Paddle Shift mode is engaged.
• Transmission shifting will be more noticeable when Paddle Shift Mode is engaged.
• To disengage Paddle Shift Mode, hold the shift lever to the right or press and hold
the (+) shift paddle until “D” is once again displayed in the instrument cluster. You
can shift in or out of the Paddle Shift Mode at any time without taking your foot off
the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a slippery surface. The drive
wheels could lose their grip and the vehicle could skid, causing a collision or
personal injury.
SELEC-TRACK™
Selec-Track™ 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-Track™ positions:
•Sport- Dry weather, on-road calibration. 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 and peak
power will be limited in the engine controls.

SUMMER/THREE-SEASON TIRES
• This vehicle may be equipped with wheels and tires to enhance traction in both
wet and dry conditions.
• Summer tires are not intended to be driven in snow or on ice.
• Summer tires have significantly reduced grip in temperatures below 50°F (10°C)
• Use summer tires only in sets of four.
NOTE:
Summer tires will not contain the all season designation or mountain/snowflake
symbol on the sidewall of the tire.
WARNING!
Do not use summer tires in snow/ice conditions. You could lose control, resulting
in severe injury or death. Driving too fast for conditions also creates the possibility
of loss of vehicle control.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the TPMS low EVIC display.
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 Belts” in “Getting Started” of this
user guide for further information.

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the potential for overheating by
taking the appropriate action:
• On the highways — slow down.
• In city traffic — while stopped, shift the transmission to NEUTRAL, but do not
increase engine idle speed.
NOTE:
There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the
engine cooling system and turning the A/C off can help remove this heat.
•
You can also turn the temperature control to maximum heat, the mode control to floor
and the blower control to high. This allows the heater core to act as a supplement to
the radiator and aids in removing heat from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately, and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming from under the hood, do not open
the hood until the radiator has had time to cool. Never try to open a cooling system
pressure cap when the radiator or coolant bottle is hot.
