24-HOUR TOWING ASSISTANCE
• Dial toll-free 1-800-521-2779 or 1-800-363-4869 for Canadian residents.
• Provide your name, vehicle identification number and license plate number.
• Provide your location, including 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. Ifyou 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/MalfunctionIndicator 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 recommend 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 coldand 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.
• 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.

• Please note that the TPMS is not a substitute for proper tire maintenance, and it isthe 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.
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 andstop 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 service center for
service if your vehicle overheats.

BRAKE- 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 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., 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 immediately.
- Electronic Stability Control OFF Warning Light
• If the ESC OFF warning light comes on continuously with the engine running, amalfunction 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
• This light shows the status of the electrical charging system. If the charging systemlight 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 thevehicle 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.
