Engine Coolant
Temperature Gage
United States Canada
This gage shows the engine coolant
temperature. Under normal driving
conditions the gage will read 210°F
(100 °C) or less. If the gage pointer
is near 260°F (125 °C), the engine
is too hot.
It means that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop the
vehicle and turn off the engine as
soon as possible.
See Engine Overheating
on
page 10‑18
for more information.
Voltmeter Gage
When the engine is not running, but
the ignition is on, this gage shows
the battery's state of charge in
DC volts.
When the engine is running, this
gage shows the condition of the
charging system. The vehicle's
charging system regulates voltage
based on the state of charge of the
battery. The voltmeter may fluctuate.
This is normal. Readings between
the low and high warning zones
indicate the normal operating range.
Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
idling for an extended period.
If there is a problem with the battery
charging system, a SERVICE
BATTERY CHARGING SYSTEM
message will appear in the Driver
Information Center (DIC) and/or the
charging system light will come on.
See Battery Voltage and Charging
Messages
on page 5‑33
for more
information.
However, readings in either warning
zone may indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.
