Except Canada

When the brake warning lamp and message appear
while the engine is running, this means:
•there is insufficient brake fluid in the reservoir
(engine running and parking brake released), or
•the parking brake is set (engine running).Note:
If you find that the minimum mark on the brake fluid
reservoir is reached, have the brake system checked for
brake pad thickness and leaks.
BRAKE
Wa r n i n g !
Driving with the brake warning lamp illuminated
can result in an accident. 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.

cluster displayPractical hints Car care Index LIGHTING SYSTEMWhen the message appears after starting the engine, or
if it comes on while driving, this indicates a failure in
the parking lamp, taillamp, stop lamp, or low beam
headlamp. See page 275 for instructions on replacing
bulbs.
If an exterior lamp fails, the message will appear only
when that lamp is switched on.
If a brake lamp fails, the message will appear when
applying the brake and stays on until the engine is
turned off.
Note:
If additional lighting is installed (e.g. auxiliary
headlamps etc.) be certain to connect into the fuse
before the failure indicator monitoring unit order to
avoid damaging the system.

battery and the other end to the positive (+) terminal
of the charged battery. Make sure the cable clamps
do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)
terminal (2) of the discharged battery.Important!
5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.
