Buick 2004 Rainier - Manual (Page 114)

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 button for the
hazard warning flashers
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 all the way down to make your front
and rear turn signal lamps flash on and off. To turn
off the flashers, press the button again until it clicks
and then release it.
When the hazard warning flashers are on, the turn
signals won’t work.
Other Warning Devices
If you carry reflective triangles, you can set one up at
the side of the road about 300 feet (100 m) behind your
vehicle.
