Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when your vehicle is at 10 volts or below. Have it
checked right away. Driving with the voltmeter reading
at 10 volts or below could drain your battery and disable
your vehicle.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
This light should come on when you start the engine.
If it does not come on then, have it fixed so it will
be ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer to Parking Brake on page 2-29
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.
