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.
Your hazard warning
flashers button is on top of
the steering column. Press
the button in to turn on
your flashers.
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, push the button down and it will
pop back up by itself.
When the hazard warning flashers are on, your turn
signals won’t work.
