Have it checked right away. Driving with the voltmeter
reading in the lower warning zone could drain or
damage the battery. Driving with the voltmeter reading
in the upper warning zone could cause bulbs to burn out
(especially headlamp bulbs), various vehicle modules to
shut down (due to overload protection) and the
possibility of a battery acid leak.
If you idle the engine for a while, the voltmeter reading
might move into the red zone. If the reading stays in the
red zone while you are driving, you may have a problem
with the electrical charging system. Have it checked.
While the voltmeter reads in the red zone, the battery
may not be able to power certain electrical accessories,
like ABS. (If this happens, the ABS light will come on.

See "Anti
Lock Brakes System Warning Light" in
this section.)
If you must drive a short distance with the voltmeter
reading in a warning zone, turn off all the accessories,
including the comfort controls and the 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 ON. If it doesn't come on then, have it
fixed so it will be ready to warn you if there's
a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. (See "Towing Your Vehicle"
in the Index.)
