Hazard Warning Flashers

The hazard warning flashers 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 flashers work no matter what
ignition position the 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.

The hazard warning
flasher button is
located on top of
the steering column.

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.

Horn

Sound the horn by pushing the center of the
steering wheel. If you have the optional air horn, it is
controlled by a cord that you will find up above and
to the left of the driver. The harder you pull on the
cord, the louder the air horn will sound. The air horn
works only after your air brake system pressure
gets up to about 115 psi (790 kPa). The air horn will
work properly unless the air brake system pressure
drops below 60 psi (415 kPa).

Tilt Wheel

A tilt wheel allows you to adjust the steering wheel
before you drive. You can raise it to the highest
level to give your legs more room when you
exit and enter the vehicle.
