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.
The "ESC Activation/Malfunction Indicator
Light" (located in the instrument cluster) starts
to flash as soon as the tires lose traction and
the ESC system becomes active. The "ESC
Activation/Malfunction Indicator Light" also
flashes when TCS is active. If the "ESC
Activation/Malfunction Indicator Light" begins
to flash during acceleration, ease up on the
accelerator and apply as little throttle as pos-
sible. Be sure to adapt your speed and driving
to the prevailing road conditions.
NOTE:
• The "ESC Activation/Malfunction Indica-
tor Light" and the "ESC OFF Indicator
Light" come on momentarily each time

TIRES — GENERAL INFORMATION

Tire Pressure

Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Three primary areas are affected by improper
tire pressure:
Safety
WARNING!
• Improperly inflated tires are dangerous and
can cause accidents.
• Under-inflation increases tire flexing and
can result in tire failure.
• Over-inflation reduces a tire's ability to
cushion shock. Objects on the road and
chuck holes can cause damage that results
in tire failure.
• Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
• Over-inflated or under-inflated tires can af-
fect vehicle handling and can fail suddenly,
resulting in loss of vehicle control.
Always drive with each tire inflated to the
recommended pressure.
Economy
Improper inflation pressures can cause uneven
wear patterns to develop across the tire tread.
These abnormal wear patterns will reduce
tread life resulting in a need for earlier tire
