light stays on, it may be an indication that the parking
brake has not been released, or there is a low brake fluid
level. 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. In this case, the light will
remain on until the condition has been corrected. If the
parking brake is applied, the light will flash when the
gear position is out of park for automatic transmissions.
If brake failure is indicated, immediate repair is neces-
sary. Operating the vehicle in this condition is danger-
ous!
23. TOW/HAUL
The TOW/HAUL button is located at the end of the gear
shift lever. This light will illuminate when the TOW/
HAUL button has been selected.
24. Malfunction Indicator Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.
