TOW/HAUL MODE
• When driving in hilly areas, towing a trailer, carrying a heavy load, etc.,and frequent transmission shifting occurs, press the TOW/HAUL switch
to select TOW/HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due to excessive
shifting. When operating in TOW/HAUL mode, transmission upshifts are
delayed, and the transmission will automatically downshift (for engine
braking) during steady braking maneuvers.
• The “TOW/HAUL Indicator Light”will illuminate in the instrument
cluster to indicate that
TOW/HAUL mode has been
activated. Pressing the switch a
second time restores normal
operation. If the TOW/HAUL mode
is desired, the switch must be
pressed each time the engine is
started.

• Turn the engine off and firmly apply the parking brake.
• Shift the transmission into PARK and remove the Key Fob.
• Attach the vehicle to the tow vehicle using a suitable tow bar and release the parking brake.
NOTE: Vehicles equipped with Quadra-Lift™ must be lowered to the “Park”
(lowest) level, and have automatic leveling disabled, before tying them down
(from the body) on a trailer or a flatbed truck. Refer to “Quadra-Lift™” in
“Off-Road Capabilities” for more information. If the vehicle cannot be
lowered to the “Park” level (for example, engine will not run), tie-downs must
be fastened to the axles (not the body). Failure to follow these instructions
may cause fault codes to be set and/or loss of proper tie-down tension.
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.
• Front or rear wheel lifts should not be used. Internal damage to the transmission or transfer case will occur if a front or rear wheel lift is
used when recreational towing.
• It is necessary to follow these steps to be certain that the transfer case is fully in NEUTRAL before recreational towing to prevent
damage to internal parts.

AUTOSTICK®
• AutoStick® is a driver-interactivetransmission feature that offers
manual gear shifting to provide
youwithmorecontrolofthe
vehicle. AutoStick® 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.
Operation
• When the shift lever is in the DRIVE position, the transmission willoperate automatically, shifting between the five available gears. To
engage AutoStick®, 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 AutoStick® mode will downshift
the transmission to the next lower gear, while using (+) to enter
AutoStick® mode will retain the current gear. When AutoStick® is active,
the current transmission gear is displayed in the instrument cluster. In
AutoStick® 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 AutoStick® mode, the transmission will automatically shift up when maximum engine speed is reached. If, h owever, AutoStick® 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.
• The system will ignore attempts to upshift at too low of a vehicle speed.
• Avoid using speed control when AutoStick® is engaged.

• Transmission shifting will be more noticeable when AutoStick® isengaged.
• To disengage AutoStick® 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 AutoStick® 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 toselect 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 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.

Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped end of the nuttoward the wheel. Lightly tighten the lug nuts.
3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased leverage. Tighten the lug nuts in a star
pattern until each nut has been tightened twice. The correct tightness of
each lug nut is 110 ft/lbs (150 N·m). If in doubt about the correct
tightness, have them checked with a torque wrench by your authorized
dealer or service station.
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure that all lug nuts are properly seated against the wheel.
CAUTION!
• Do not attempt to raise the vehicle by jacking on locations otherthan those indicated in the Jacking Instructions for this vehicle.
• Be sure to mount the spare tire with the valve stem facing outward. The vehicle could be damaged if the spare tire is mounted
incorrectly.
WARNING!
• Do not attempt to change a tire on the side of the vehicle close tomoving traffic. 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.
• Always park on a firm, level surface as far from the edge of the
roadway as possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Set the parking brake firmly and set an automatic transmission in PARK.
