Pontiac 2004 Grand Prix - Manual (Page 108)

Hazard Warning Flashers
Your hazard warning flashers let you warn others.
They also let police know you have a problem.
Your front and rear turn signal lamps will flash on
and off.
The hazard warning
flasher button is located
on top of the steering
column.
The hazard warning flashers work no matter what
position your key is in, and even if the key isn’t in.
Press the button to make your front and rear turn signal
lamps flash on and off. Press the button again to turn
the flashers off.
When the hazard warning flashers are on, your turn
signals and brake lamps won’t work.
