Charging System Light
The red charging
system light is above
your oil temperature
gage on your
instrument cluster and
will come on briefly
when you turn on the
ignition, but the
engine is not running,
as a check to show
you it is working.
It should go out once the engine is running. If it stays on, or comes
on
while
you are driving, you may have a problem with the charging system. It could
indicate that you have problems with a generator drive belt, or another
electrical problem. Have it checked right away. Driving while this light is on
could drain your battery.
If you must drive a short distance with the light on, be certain to turn off all
your accessories, such as the radio and air conditioner.
Check Gages Light
HECK
GAGES
This amber CHECK
GAGES light is above
the fuel gage on the
instrument cluster and
will come on briefly
when you are starting
the engine.
If the light comes on and stays on while you are driving, check your coolant
temperature and engine oil pressure gages to see if they are in the warning
zones.
