Gages
can
indicate when
there may be or is a problem with one
of your
vehicle's functions. Often gages and warning lights work together
to let
you
know when there's a problem with your vehicle.
When one of the warning lights comes on and stays on when you are
driving, or when one of the gages shows there may be a problem, check the
section that tells
you
what to do about it. Please follow the manual's advice.
Waiting to do repairs can be costly
-
and even dangerous. So please get to
know your warning lights and gages. They're a big help.
Brake System Warning Light
Standard Cluster
Digital Cluster
Your vehicle's hydraulic brake system is divided into two parts. If one part
isn't working, the other part can still work and stop you. For good braking,
though, you need both parts working well.
If the warning light comes on, there could be a brake problem. Have your
brake system inspected right away.
This light should come on as you start the vehicle. If it doesn't come on
then, have it fixed so it will be ready to warn you if there's a problem.
If the light comes on while you are driving, 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 floor. It may take longer to stop. If the light is still on, have
the vehicle towed for service. (See "Towing Your Vehicle'' in the Index.)
