INSTRUMENT CLUSTER WARNING LIGHTS
- Electronic Stability Control (ESC) Malfunction Indicator Light
• If the “ESC Malfunction Indicator Light” comes on continuously with the engine running, amalfunction 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), we recommend you drive to the nearest service center as
soon as possible to have the problem diagnosed and corrected.
• The “ESC Malfunction Indicator Light” starts to flash as soon as the tires lose traction and the ESC system becomes active. If the light begins to flash during acceleration, ease up
on the accelerator and apply as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions. The light also flashes when TCS is active. 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.
- Tire Pressure Monitoring System (TPMS) Light
• A Tire Pressure Monitoring Light and a “low tire” message will display in your instrumentcluster along with an audible chime if one or more of your vehicle’s four road tires are
significantly under-inflated.
• Check the inflation pressure of each tire and inflate to the recommended pressure for your vehicle. The tire pressures recommended for your vehicle are found on the “Tire and
Loading Information” label located on the driver’s side door opening. The TPMS light
should not be used as a tire pressure gauge when adjusting your tire pressure.
• It is recommended that you check the tire pressure in the morning when tires are cool; inflate each tire to the recommended pressure for your vehicle. The light will turn off
after your vehicle’s tire pressures are properly inflated and the pressure has been
recognized. The vehicle may need to be driven for up to 20 minutes above 15 mph
(25 km/h) before the light will turn off.
• Temperature changes can affect tire pressure, causing the TPMS light to turn on. Tire pressures will also increase as the vehicle is driven – this is normal and you should not
adjust for this increased pressure.
• Driving on under-inflated tires reduces your vehicle’s fuel efficiency and tire tread life. If a spare tire is in use on the vehicle, the TPMS light may turn on.

WHAT TO DO IN EMERGENCIES

- 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 stopthe 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.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant. You may want to call an authorized dealership for service if
your vehicle overheats.
- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or theparking brake is applied. If the light is on and the parking brake is not applied, it
indicates a possible brake hydraulic malfunction, brake booster problem or an Anti-Lock
Brake System problem.
• We recommend you drive to the nearest Service Center and have the vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have an accident.
Have the vehicle checked immediately.
- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., mayilluminate the MIL after engine start. The vehicle should be 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 as soon as possible if this
occurs.

WHAT TO DO IN EMERGENCIES

Fuel Cap/Loose Gas Cap Message
• If a “gas cap” message (shown as gASCAP) appears, tighten the gas cap until a “clicking”sound is heard.
• Press the odometer reset button to turn the message off.
• If the message continues to appear for more than three days after tightening the gas cap, see your authorized dealer.
Oil Change Indicator
Message
• 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 takingthe appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into 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 Fan 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.
• 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.
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.
