This indicator should come on when
the ignition switch is ON (II), and go
out af ter the engine starts. If it
comes on brightly when the engine
is running, it indicates that the
charging system has stopped
charging the battery.By eliminating as much of the
electrical load as possible, you can
drive several miles (kilometers)
before the battery is too discharged
to keep the engine running. Drive to
a service station or garage where
you can get technical assistance.
Immediately turn of f all electrical
accessories: radio, heater, A/C,
cruise control, etc. Try not to use
other electrically-operated controls
such as the power windows. Keep
the engine running and take extra
care not to stall it. Starting the
engine will discharge the battery
rapidly.
