rear turn signal lamps will flash on and off.

The hazard flasher switch is located on the steering column.
Press the button in to make your front and rear turn
signal lamps flash on and off.
Your hazard warning flashers work no matter what

To turn off the flashers, pull out on the collar. When
the hazard warning flashers are on, your turn signals
won't work.
