Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag” in the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed so it will be
ready to warn you if there is a problem.
Voltmeter
You can read 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 yellow zone. If the reading
stays in the yellow zone while you are driving, you may
have a problem with the electrical charging system.
Have it checked. While the voltmeter reads in the yellow
zone, your battery may not be able to power certain
electrical accessories, like ABS. (If this happens, your
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.
