5-8 Instruments and Controls
Have it checked right away. If a
short distance must be driven with
the light on, be certain to turn off all
the accessories.

Brake System Warning

Light

With the ignition in ON/RUN, the
brake system warning light comes
on when the parking brake is set.
If the vehicle is driven with the
parking brake engaged, a chime
sounds when the vehicle speed is
greater than 8 km/h (5 mph).
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on and a
chime sounds there could be a
brake problem. Have the brake
system inspected right away.
This light also comes on due to low
brake fluid. See the owner manual
for more information.
Metric
This light should come on briefly
when the ignition key is turned to
ON/RUN. If it does not come on
then, have it fixed so it will be ready
to warn if there is a problem.
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.
English
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push
or can go closer to the floor. It may
take longer to stop. If the light does
not go out, have the vehicle towed
for service. See General Towing
Information on page 9 9.
