Fog Lamps

If equipped with fog lamps, the
button is on the exterior lamp
control, to the left of the steering
column.
The ignition must be in the ON/RUN
position for the fog lamps to
come on.
: Press to turn the fog lamps on
or off. A light will come on in the
instrument cluster.
When the fog lamps are turned on,
the parking lamps automatically
turn on.
When the headlamps are changed
to high beam, the fog lamps also go
off. When the high-beam headlamps
are turned off, the fog lamps will
come on again.
Some localities have laws that
require the headlamps to be on with
the fog lamps.
