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.
Your hazard warning flashers work no matter what
position your key is in, and even if the key is not in the
ignition.
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 will not work.
Other Warning Devices
If you carry reflective triangles, you can set them up at
the side of the road about 300 feet (100 m) behind
your vehicle.
