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
need to be working.If the warning light comes on, there
is a brake problem. Have the
brake system inspected right away.
This light should come on briey
when the ignition key is turned
to ON/RUN. If it does not come on
then, have it xed so it will be
ready to warn if there is a problem.
This light may also come on due
to low brake uid. SeeBrakes
on page 5-25for more information.
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
fully. If it stays on after the
parking brake is fully released, it
means there is a brake problem.
