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 button.
This will improve performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When operating in
TOW/HAUL mode, the transmission will shift into third gear.
NOTE:The TOW/HAUL mode locks
out Overdrive.
• The “TOW/HAUL Indicator Light”will illuminate in the instrument
cluster to indicate when the
switch 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.
RECREATIONAL TOWING (BEHIND MOTORHOME,
ETC.)
Recreational Towing — Two-Wheel Drive Models
• Recreational towing is allowed if the rear wheels are OFFthe ground.
This may be accomplished using a tow dolly or vehicle trailer. If using a
tow dolly, follow this procedure:
• Properly secure the dolly to the tow vehicle, following the dolly manufacturer's instructions.
• Drive the rear wheels onto the tow dolly, firmly set the parking brake and place the transmission in PARK.
• Turn the ignition switch to the unlocked OFF position.
• Install a suitable clamping device, designed for towing, to secure the front wheels in the straight position.
• Disconnect the negative battery cable and secure it away from the battery post.
• Flat towing (with all four wheels on the ground) is allowed ONLY if the
driveshaft is removed. Towing with the rear wheels on the ground while
the driveshaft is connected will result in severe transmission damage.

• The parking brakemustbe firmly engaged and the wheels chocked
during driveshaft removal and installation. The parking brake must
remain engaged unless the vehicle is securely and properly connected to
the tow vehicle, or the driveshaft is completely reinstalled. See your
authorized dealer for proper driveshaft removal and reinstallation
procedures, including flange orientation/alignment, use of thread-locking
compound, proper bolt torque specifications, etc.
Towing – Four-Wheel Drive Models
• Depress the brake pedal and turn the ignition switch to ON/RUN
with the engine shut off.
• Shift the transmission into NEUTRAL.
• Shift the transfer case into NEUTRAL by holding down the
NEUTRAL Pin switch for four
seconds until the LED starts to
blink. The LED will stop blinking
and remain on when the shift is
complete.
• Start the engine and shift into DRIVE to ensure there is no vehicle movement.
• Shut the engine off and shift the transmission into PARK.
• Place the ignition switch in the OFF position and remove the key.
• Apply the parking brake, attach the vehicle to the tow vehicle with a tow bar and release the parking brake.
• Refer to your Owner's Manual on the DVD for further details.
CAUTION!
Towing with the rear wheels on the ground (while the driveshaft is
connected) will cause severe transmission damage. Damage from
improper towing is not covered under the New Vehicle Limited
Warranty.
WARNING!
• If the driveshaft is removed, the vehicle can roll even if the transmission is in PARK, which could cause serious injury or death.

• Please note that the TPMS is not a substitute for proper tiremaintenance, 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 tire pressure telltale.
• 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. Aftermarket 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.
- Engine Temperature Warning Light
• This light warns of an overheated engine condition.
• If the light turns on and a warning chime sounds while driving, safely pull over and stop the vehicle. If the A/C system is on, turn it off. Also, shift
the transmission into NEUTRAL and idle the vehicle. If the temperature
reading does not return to normal, turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.

serviced if the light stays on through several typical driving cycles. In
most situations, the vehicle will drive normally and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic
converter damage. We recommend you do not operate the vehicle. Have
the vehicle serviced immediately.
- Electronic Stability Control OFF Warning Light
• If the ESC OFF warning light comes on continuously with the enginerunning, a malfunction has been detected.
• If this light remains on after several ignition cycles, and the vehicle has been driven several miles (kilometers) at speeds greater than 30 mph
(48 km/h), we recommend you drive to the nearest service center and
have the vehicle serviced immediately.
- Charging System Light

Oil Change IndicatorMessage• If an “oil change” message (shown as CHAngE OIL) appears and a single chime sounds, it is time for your next required oil change.
Resetting The Light After Servicing
• Turn the ignition switch to the ON/RUN position (do not start engine).
• Fully depress the accelerator pedal three times within 10 seconds.
• Turn the ignition switch to the OFF/LOCK position.
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, place the transmission in 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 240°F (116 °C) or greater pull over and stop
the vehicle. Idle the vehicle with the air conditioner turned off until the
pointer drops back into the normal range 200–230°F (93–110°C). If
the pointer remains at 240°F (116°C) or greater and you hear a chime,
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.

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.
• Do not attempt to change a tire on the side of the vehicle close to moving traffic, pull far enough off the road to avoid being hit when
operating the jack or changing the wheel.
• Carefully follow these tire changing warnings to help prevent personal injury or damage to your vehicle.
• 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; a manual transmission in REVERSE.
• Never start or run the engine with the vehicle on a jack.
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack.
• Only use the jack in the positions indicated and for lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely careful of motor traffic.
• Raising the vehicle higher than necessary can make the vehicle less stable and cause a collision. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to remove the tire.
• A loose tire or jack, thrown forward in a collision or hard stop, could endanger the occupants of the vehicle. Always stow the jack parts
and the spare tire in the places provided.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the lug nuts fully until the vehicle is lowered to the ground.
