Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking brake ap-
plication. If the brake light turns on it may indicate that the parking brake is applied, that the
brake fluid level is low, or that there is a problem with the anti-lock brake system reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it indicates a possible brake hydraulic system
malfunction or that a problem with the Brake Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability Control (ESC) system. In this case, the light will
remain on until the condition has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake, and a brake pedal pulsation may
be felt during each stop.

The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.

WARNING! (Continued)
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
placing the ignition in the position ON/RUN position.
The light should illuminate for approximately two sec-
onds. The light should then turn off unless the parking
brake is applied or a brake fault is detected. If the light
does not illuminate, have the light inspected by an
authorized dealer.

Engine Temperature Warning Light
This light warns of an overheated engine condition. As engine coolant temperatures rise and
the gauge approaches

reaching a set threshold. Further overheating will cause a continuous chime sound for
4 minutes, or until the engine is allowed to cool, whichever comes first.
If the light turns on while driving, safely pull over and stop the vehicle. If the A/C system
is on, turn it off. Also, shift the transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the engine off immediately and call for
