ROADSIDE ASSISTANCE • Dial toll-free 1-800-521-2779 for U.S. Residents or 1-800-363-4869 for Cana-
dian Residents.
• Provide your name, vehicle identification number, license plate number, and your
location, including the telephone number from which you are calling.
• Briefly describe the nature of the problem and answer a few simple questions.
• You will be given the name of the service provider and an estimated time of arrival.
If you feel you are in an “unsafe situation”, please let us know. With your consent,
we will contact local police or safety authorities.
INSTRUMENT CLUSTER WARNING LIGHTS - Electronic Stability Control (ESC) Activation/Malfunction Indicator Light• 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), we recom-
mend you drive to the nearest service center and have the vehicle serviced
immediately.
• The “ESC Activation/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• 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) that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accordingly, when the low tire
pressure telltale 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.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
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.
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 dealer for service if
your vehicle overheats.
BRAKE
- Brake Warning Light• The Brake Warning light illuminates when there is either a system malfunction or
the parking 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.
• Please have your 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 a collision.
Have the vehicle checked immediately.
- Malfunction Indicator Light (MIL)• Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., may
illuminate 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 immediately.
Electronic Stability Control (ESC) OFF Activation/Malfunction Warning Light
• If the ESC OFF warning light comes on continuously with the engine running, 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.WHAT TO DO IN EMERGENCIES

On Electronic Vehicle Information Center (EVIC) equipped vehicles, “Oil Change
Required” will be displayed in the EVIC and a single chime will sound, indicating that
an oil change is necessary.
On Non-EVIC equipped vehicles, “Change Oil” will flash in the instrument cluster
odometer and a single chime will sound, indicating that an oil change is necessary.
Your authorized dealer will reset the oil change indicator message after completing
the scheduled oil change. If a scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by referring to the steps
described under “Electronic Vehicle Information Center (EVIC)/Oil Change Re-
quired” in “Understanding Your Instrument Panel” or under “Instrument Cluster
Description/Odometer/Trip Odometer” in “Understanding Your Instrument Panel” for
further information.
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km)
or twelve months, whichever comes first.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder, power
steering and automatic transmission, and fill as needed
• Check function of all interior and exterior lights
Required Maintenance Intervals .
Refer to the maintenance schedules on the following page for the required mainte-
nance intervals. At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•
Change oil and filter
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil
indicator system turns on.
•
Inspect battery and clean and tighten terminals as required
•
Inspect automatic transmission fluid if equipped with dipstick
•
Inspect brake pads, shoes, rotors, drums, hoses and park brake
•
Inspect engine cooling system protection and hoses
•
Inspect exhaust system
•
Inspect engine air cleaner if using in dusty or off-road conditions
•
Inspect all door latches for presence of grease, reapply if necessary.MAINTAINING YOUR VEHICLE
