Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or in a position between on and start, or
by applying the parking brake when the ignition is turned to the on
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level and the
brake system should be inspected immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness:If this light fails
to illuminate when the ignition is
turned to on, continues to flash or
remains on, have the system
serviced immediately by your authorized dealer. A chime will sound
when there is a malfunction in the indicator light.
Safety belt:Reminds you to fasten
your safety belt. A Belt-Minder

chime will also sound to remind you
to fasten your safety belt. Refer to
theSeating and Safety Restraints
chapter to activate/deactivate the Belt-Minder
chime feature.

Europe to ensure lamp performance, light brightness and pattern and safe
visibility. The correct bulbs will not damage the lamp assembly or void the
lamp assembly warranty and will provide quality bulb burn time.
