when you start your vehicle to make sure the bulb works. If any light
remains on after starting the vehicle, refer to the respective system
warning light for additional information.
Note:Some warning lights are
reconfigurable telltale (RTT)
indicator lights and illuminate in the
message center. These lights
function the same as the other
warning lights.
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 is also illuminated.
Brake system warning light:To
confirm the brake system warning
light is functional, it momentarily
illuminates 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 takes 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.
