INSTRUMENT CLUSTER WARNING LIGHTS
- Tire Pressure Monitoring System (TPMS) Light
Each tire, including the spare (if provided), should be checked monthly, when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a Tire Pressure
Monitoring System (TPMS) which display in the Electronic Vehicle Information
Center (EVIC) when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure EVIC display illuminates, you should stop and
check your tires as soon as possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE AIR
PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE PLACARD OR
TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.
NOTE:
After inflation, the vehicle may need to be driven for 20 minutes before the flashing light
will turn off.

- Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called
OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition
checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through several of your typical
driving cycles. In most situations, the vehicle will drive normally and will not require
towing.
CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause
damage to the engine control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic converter damage and power
loss will soon occur. Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced above, can reach higher tempera-
tures than in normal operating conditions. This can cause a fire if you drive slowly or
park over flammable substances such as dry plants, wood, cardboard, etc. This could
result in death or serious injury to the driver, occupants or others.
- Electronic Stability Control (ESC) Activation/Malfunction Indicator Light
The “ESC Activation/Malfunction Indicator Light” in the instrument cluster will
come on when the ignition switch is turned to the ON/RUN position. It should go out
with the engine running. If the “ESC Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a malfunction has been detected in the
ESC system. 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), see
your authorized dealer as soon as possible to have the problem diagnosed and
corrected.
NOTE:
• The “ESC Off Indicator Light” and the “ESC Activation/Malfunction Indicator
Light” come on momentarily each time the ignition switch is turned to ON/RUN.
• Each time the ignition is turned to ON/RUN, the ESC system will be ON, even if
it was turned off previously.
WHAT TO DO IN EMERGENCIES
153

• The ESC system will make buzzing or clicking sounds when it is active. This is
normal; the sounds will stop when ESC becomes inactive following the maneuver
that caused the ESC activation.
• To improve the vehicle's traction when starting off in deep snow, sand or gravel, it
may be desirable to switch the ESC system to Partial Off mode by momentarily
pressing the ESC Off
switch located below the climate controls, on the switch
panel.
- Electronic Stability Control (ESC) OFF Indicator Light
This light indicates the Electronic Stability Control (ESC) is off.
- Charging System Light
This light shows the status of the electrical charging system. If the charging system
light remains on, it means that the vehicle is experiencing a problem with the
charging system.
We recommend you do not continue driving if the charging system light is on. Have
the vehicle serviced immediately.
- Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the
ignition switch is turned to the ON/RUN position and may stay on for as long as four
seconds.
If the ABS light remains on or turns on while driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that service is required. However,
the conventional brake system will continue to operate normally if the BRAKE
warning light is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have the light inspected by an
authorized dealer.

- Electronic Throttle Control (ETC) Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition key when the vehicle has completely stopped and the shift lever/gear selector
is placed in the PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized service center immediately. If the light is flashing when the
engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require towing.
- Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb check when the ignition
switch is first turned to the ON/RUN position. If the light is either not on during
starting, stays on, or turns on while driving, have the system inspected at an
authorized dealer as soon as possible. Refer to “Occupant Restraints” in “Things To
Know Before Starting Your Vehicle” of your Owner’s Manual for further information.
NOTE:
The Air Bag System is designed to be maintenance free.

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.

Do not raise the vehicle until you are sure the jack is fully engaged.
6.
Raise the vehicle by turning the jack
screw clockwise. Raise the vehicle only
until the tire just clears the surface and
enough clearance is obtained to install
the spare tire. Minimum tire lift pro-
vides maximum stability.
7. Remove the lug nuts and wheel.
8.
Position the spare wheel/tire on the
vehicle and install the lug nuts with
the cone-shaped end toward the wheel.
Lightly tighten the nuts.
9. Lower the vehicle by turning the jack
screw counterclockwise, and remove
the jack and wheel blocks.
10. 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 wheel nut tight-
ness is 130 ft lbs (176 N·m). If in
doubt about the correct tightness,
have them checked with a torque
wrench by your authorized dealer or
at a service station.
11. Lower the jack to the fully closed position and return it and the tools to the
proper positions in the foam tray.
12. Remove the small center cap and securely store the road wheel in the cargo area.
13. Have the aluminum road wheel and
tire repaired as soon as possible,
properly secure the spare tire with
the special wing nut torqued to
3.7 ft-lbs (5 N·m), reinstall the jack
and tool kit foam tray, and latch the
rear load floor cover.

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.
