closed with the ignition switch turned to the “ACC” or “LOCK”\
position.* To turn them on again, turn the ignition switch to the
“ON” position, or turn the headlight switch off and then twist the
knob until the first or second clickstop. If you are going to park
for over one week, make sure the headlight switch is off.
