Features & Controls
Shift Light
(MANUAL TRANSAXLE)
This light comes on when you need to
shift to the next higher gear. See the
Index under Manual Transaxle.
Malfunction Indicator Lamp
(Check Engine Light)
A computer monitors operation of your
fuel, ignition and emission control
systems. This light should come on
when the ignition is on, but the engine
is not running, as a check to show you it
is working. If it does not come on at all,
have it fixed right away. If it stays on, or
it comes on while you are driving, the
computer is indicating that you have a
problem. You should take your vehicle
in for service soon.
If you keep driving your vehicle
with this light on, after a while the
emission controls won't work as
well, your fuel economy won't be
as good and your engine may not
run as smoothly. This could lead to
costly repairs not covered by your
m . .
