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
the instrument panel
above the navigation
system.
Your hazard warning flashers work no matter what
mode the ignition is in, even if the ignition is turned off.
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.
Other Warning Devices
If you carry reflective triangles, you can set one up at
the side of the road about 300 feet (100 m) behind your
vehicle.
