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.
