Warning Lights,
Gages, and Indicators
Warning lights and gages can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gages could
prevent injury.
Warning lights come on when there
may be or is a problem with one
of the vehicle’s functions. Some
warning lights come on briey when
the engine is started to indicate
they are working.Gages can indicate when there may
be or is a problem with one of the
vehicle’s functions. Often gages and
warning lights work together to
indicate a problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual’s advice.
Waiting to do repairs can be
costly and even dangerous.

miles or kilometers.
This vehicle has a tamper-resistant
odometer. If the vehicle needs a
new odometer installed, the new one
will be set to the mileage total of
the old odometer. If this is not
possible, it will be set at zero and a
label must be put on the driver’s
door to show the old mileage
reading when the new odometer
was installed. If the mileage is
unknown, the label should then
indicate “previous mileage
unknown”.
Tachometer
The tachometer displays the
engine speed in revolutions per
minute (rpm).

Voltmeter Gage
When the engine is not running, but
the ignition is turned 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 uctuate.
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. SeeDIC Warnings and
Messages on page 3-56and
Charging System Light on page 3-37
for more information.
However, readings in either warning
zone may indicate a possible
problem in the electrical system.

seeDIC Warnings and Messages
on page 3-56.Here are some situations that may
occur with the fuel gage. None
of these indicate a problem with the
fuel gage.
At the gas station, the fuel
pump shuts off before the
gage reads full.
It takes a little more or less fuel
to ll up than the fuel gage
indicated. For example, the gage
may have indicated the tank
was half full, but it actually took a
little more or less than half the
tank’s capacity to ll the tank.
The gage goes back to empty
when the ignition is turned off.
