Brake Warning Lamp

The brake warning lamp will come on
if insufficient brake fluid is in the
reservoir (key in steering lock posi­
tion 2 and parking brake released).
When the minimum mark on the
reservoir is reached, have the brake
system checked for brake pad thick­
ness and leaks.
To test the brake warning lamp, turn
key in steering lock to position 2. The
brake warning lamp comes on, and
should go out when the engine is
running.
W arning!
Driving with the brake warning
lamp on, can result in an acci­
dent. Have your brake system
checked immediately if the brake
warning lamp stays on. Don't add
brake fluid before checking the
brake system. Overfilling the
brake fluid reservoir can result in
spilling brake fluid on hot engine
parts and the brake fluid catching
fire. You can be seriously burned.
