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’s
instructions.
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.
UTILITY
132

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.
JACKING AND TIRE CHANGING
Run Flat Tires — SRT Only
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.
NOTE:
This vehicle may be equipped with a spare tire. The spare tire must be used for the
rear wheel(s) only. For a flat front tire, move the rear tire to the front and use the spare
tire on the rear.

WARNING!
• 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 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.
• 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.
• To assure that spare tires, flat or inflated, are securely stowed, spares must be
stowed with the valve stem facing the ground.
• Carefully follow these tire changing warnings to help prevent personal injury or
damage to your vehicle.
• Raising the vehicle higher than necessary can make the vehicle less stable. It
could slip off the jack and hurt someone near it. Raise the vehicle only enough
to remove the tire.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the wheel
nuts fully until the vehicle has been lowered. Failure to follow this warning may
result in personal injury.
• 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. Have the deflated (flat) tire repaired or replaced imme-
diately.
