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 located on
top of the steering column.
Your 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 the 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 won't work. The hazard warning flashers will
not flash if the brakes are applied.

latching. Make sure the secondary latch (if equipped)
keeps the hood from opening all the way when the
primary latch is released.
