Delayed Headlamps
The delayed headlamps feature provides a period of
exterior lighting as you leave the area around your
vehicle. The feature is activated when the headlamps
are on due to the automatic headlamps control
feature described previously in this section, and when
the ignition is turned off. Your headlamps will then
remain on until the exterior lamps control is moved from
OFF to the parking lamps position or until either a
30 second or 60 second lighting period has ended.
If you turn
off
the ignition with the headlamps switch in
the parking lamps or headlamps position, the delayed
headlamps cycle will not occur.
To disable the delayed headlamps feature or change
the time of delay, see Vehicle Custornization Settings on
page 3-90.
If your vehicle is equipped
with fog lamps, the button
is located on the
instrument panel next to
the exterior lamps
control wheel to the left of
the steering column.
Your ignition must be in ON for the fog lamps to
illuminate.
To turn the fog lamps on, press the FOG button. A light
will come on in the button to let you know that the
fog lamps are on. Press the FOG button again to turn
the fog lamps off.
Your parking lamps must be on or your fog lamps won't
come on.
The fog lamps will go
off
whenever you change to
high-beam headlamps. When you return to low beams,
the fog lamps will come on again.
