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 lights will flash on and off.
Slide the switch up to make your front
and rear turn signal lights flash on and
off.
Your hazard warning flashers work no
matter what position your key is in, and
even if the key isn't in.
To turn off the flashers, slide the switch
down. 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.
