the left side of the instrument panel.
The parking lamps and/or low-beam
headlamps must be on for the fog
lamps to work.

fog lamps on or off. An indicator
light comes on when the fog lamps
are in use.
The fog lamps go off whenever the

When the high beams turn off, the
fog lamps come on again.
The fog lamps are cancelled after
the ignition is turned off. If you still
want to use the fog lamps after the
vehicle is restarted, press the fog
