132 GETTING TO KNOW YOUR INSTRUMENT PANEL
CAUTION!
Prolonged driving with the Malfunction Indica-
tor Light (MIL) on could cause damage to the
vehicle control system. It also could affect
fuel economy and driveability. If the MIL is
flashing, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.

greater than 30 mph (48 km/h), see an
authorized dealer as soon as possible to have
the problem diagnosed and corrected.


an ESC event.
