MALFUNCTION INDICATOR LAMP/
CHECK ENGINE LIGHT
If this indicator comes on while
driving, there is a problem with
your engine or its emission
control systems. Even though you
may feel no difference in your
car's performance, it can reduce
your fuel economy and cause
your car to put out excessive
emissions. Continued operation
may cause serious damage.
Taking Care of the Unexpected
If this indicator comes on, safely
pull off the road and turn off the
engine. Restart the engine and
watch the indicator. If it stays on,
have your car checked by the
dealer as soon as possible. Drive
moderately until the dealer has
inspected the problem. Avoid
full-throttle acceleration and
driving at high speed.
You should also have the dealer
inspect your car if the indicator
comes on frequently, even though
it goes off when you follow the
above procedure.
NOTICE
If you keep driving with the
malfunction indicator lamp/check
engine light on, you can damage
your car's emission controls and
engine. Those repairs may not be
covered by your car's warranties.
