GMC 2007 Automobile User Manual


 
Charging System Light
The charging system
light will come on briefly
when you turn on the
ignition, and the engine
is not running, as a
check to show you it
is working.
Then it should go out when the engine is started.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging
system. Have it checked by your dealer. Driving
while this light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
Anti-Lock Brake System
Warning Light
If your vehicle has an
Anti-Lock Brake
System (ABS), this light
will come on when the
ignition is turned to ON
and may stay on for
several seconds.
That is normal.
If the light stays on, turn the ignition to LOCK. If the
light comes on, stop as soon as possible and turn
the ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on
again while you are driving, your vehicle needs
service. See your dealer. If the regular brake
system warning light is not on, you still have brakes,
but you do not have anti-lock brakes. If the regular
brake system warning light is also on, you do not
have anti-lock brakes and there is a problem with
your regular brakes. See Brake System Warning
Light on page 164.
