Voltmeter
You can read the battery
voltage on your voltmeter.
If it reads less than 11 volts
or more than 16 volts while
your engine is running, and
it stays there, you may
have a problem with the
electrical charging system.
Have it checked right away. Driving with the voltmeter
reading in a warning zone could drain your battery.
If you idle your engine for a while, the voltmeter reading
might move into the low voltage zone (indicated by
red dots). If the reading stays in the low voltage zone
while you are driving, you may have a problem with the
electrical charging system. Have it checked. While the
voltmeter reads in the low voltage zone, your battery
may not be able to power certain electrical accessories,
like ABS. (If this happens, the ABS INOP light will
come on. See “Anti
-
Lock Brake System Warning Light”
in the Index.)
If you must drive a short distance with the voltmeter
reading in a warning zone, turn off all your accessories,
including your air conditioning and audio system.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.

This light should come on briefly when you turn the
ignition key to RUN. If it doesn’t come on then, have it
fixed so it will be ready to warn you if there’s a problem.
