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.
Have the vehicle serviced as soon
as possible.
Brake System Warning
Light
This vehicle’s hydraulic brake
system is divided into two parts.
If one part is not working, the other
part can still work and stop the
vehicle. For good braking both parts

When the ignition is on, the
brake system warning light will also
come on when the parking brake
is set. The light will stay on if
the parking brake does not release

conditions the gage will read
approximately 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

A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light comes on when the ignition
is on, but the engine is not running,
as a check to show it is working. If it
does not, have the vehicle serviced

When the fuel tank is low on fuel,
the FUEL LEVEL LOW message will
appear on the Driver Information
Center (DIC). For more information
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.
