The hazard warning
flasher button is located
near the center of the
instrument panel.
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 will not work.
