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.
But they won't flash if you're braking.
The hazard warning flasher
button is located on the 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. To turn the flashers off, press the
button until the first click and release.
When the hazard warning flashers are on, your turn
signals won't work.
Other Warning Devices
If you carry reflective triangles, you can use them to
warn others. Set one up at the side of the road about
300 feet (100 m) behind your vehicle.
