inspection if:

engine is running.
.
The light does not come on
when the ignition is in

Critical emission control
systems have not been

several days of routine
driving before the system is
ready for inspection. This

Brake System
Warning Light
Metric
English
This light comes on briefly
when the vehicle is turned on
to show that the light is
working. If it does not come on
then, have it fixed so it will be
ready to warn you if there is a
problem.
If the light comes on and stays
on, there is a brake problem.
Have the brake system
inspected right away. This
light may come on if the brake
fluid is low. See Brake Fluid
If the light comes on while
driving, pull off the road and
stop carefully. The brake
system has electric brake
boost. Vehicle speed may be
limited when the brake system
warning light comes on. The
brake pedal might be harder to
push, or the brake pedal may
go closer to the floor. It could
take longer to stop. If the light
is still on, have the vehicle
towed for service. See

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.
