Low Coolant Warning Light
The orange Low
Coolant Warning
light, if
you have one,
is located in the upper
left corner of the
instrument cluster.
If
you have a diesel engine, you have a low coolant light. If this light comes
on anytime the engine is running, your system is low on coolant and the
engine may overheat. See “Engine Coolant”
in the Index and have your
vehicle serviced
as soon as you can.
Charging System Warning Light
The red Charging
System Warning light
is located at the upper
right corner of the
instrument cluster.
The Charging System Warning light should come on briefly when you turn
on the ignition, before starting the engine, as a check to show you it is
working. After the engine starts, the light should go out. If it stays on or
comes
on while you are driving, you may have a problem with your
charging system. It could indicate a problem with the alternator drive belt,
or
some other charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If
you must drive a short distance with this light on, it helps to turn off all
your accessories, such
as the radio and air conditioner.

A reading in the low pressure zone may be caused by a dangerously low oil
level or other problem causing low oil pressure. Check your oil as soon as
possible.
I NOTICE:
Damage to your engine from neglected oil problems can be
costly and
is not covered by your warranty.

When your engine is not running, but the ignition is on (in the RUN
Position), this gage shows your battery’s state of charge in DC volts. When
the engine is running, the gage shows the condition
of the charging system.
Readings between the
low and high warning zones indicate the normal
operating range.
Readings
in either warning zone indicate a possible problem in the electrical
system.
