When the ignition is on, the brake system warning
light will also come on when you set your parking brake.
The light will stay on if your parking brake does not
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes on while you are driving, a chime will
sound and you should pull off the road and stop carefully.
You may notice that the pedal is harder to push. Or, the
pedal may go closer to the oor. It may take longer to
stop. If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-26.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
Antilock Brake System (ABS)
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this light
comes on briey when
the engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the
light comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-35.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-56for
all brake related DIC messages.

performs the following for each trip odometer:
If the vehicle’s speed has exceeded 3 mph (5 km/h)
during the current ignition cycle, this function will
set the trip odometer to the distance driven
during the current ignition cycle.

(5 km/h), this function will set the trip odometer
to the distance driven during the previous ignition
cycle plus the distance driven during the current
ignition cycle.
