Hazard Warning Flashers - GMC 2000 Envoy Owner's Manual

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.
5-2
Your hazard warning flashers work no matter what
position your key is in, and even if the key isn't in.
To turn off the flashers, press the button until the first
click and release.
When the hazard warning flashers are on, your turn
signals won't work.
Press the button on top of
the steering column all the
way down to make your
front and rear turn signal
lamps flash on and off.
