Low Coolant Warning Light or Message
LOW
COOLANT
If the engine is running and
this warning light comes on,
or the information center
displays LOW ENGINE
COOLANT, your system
may be low on coolant and
the engine may overheat.
A warning chime will also sound. See "Engine Coolant"
in the Index and check your coolant level at the coolant
recovery
tank.
If the level is low, bring it up to its proper
level. If the level is not low, have your low coolant
warning system serviced.
The LOW COOLANT warning light will also come on
when you turn on the ignition as a bulb check to show
you it is working. If
it
doesn't come on then, have it
fixed right away. After the bulb check, the light will go
out for 20 seconds. If the light comes back on after
20 seconds, the system may be low on coolant.
CHECK
Malfunction Indicator Lamp
(Check Engine)
A computer monitors
operation of your fuel,
ignition and emission
controls systems. This
warning 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.
NOTICE:
If you keep driving your vehicle with this
warning light on, after awhile 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 warranty.
