When you turn the key to RUN, this light will come on
briefly, to show that your alternator and battery charging
systems are working.

at
once. To save your battery until
you get there, turn off
all accessories, and set your air system to OFF.

This gage shows the voltage in the electrical system.
The normal range is
11 to 15 volts. If the reading stays
outside the normal range, have your Buick dealer check
the electrical system.
