Automatic Headlamp System
When it is dark enough outside, your automatic system
will turn on your headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, parking lamps, instrument panel lights, and
interior switch backlighting.
Your vehicle has a light sensor on top of the instrument
panel. Make sure it is not covered, or the headlamps
may remain on when you do not need them.
The system may also be on when driving through a
parking garage, heavy overcast weather or a tunnel.
This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the automatic lamp control
system so that driving under bridges or bright overhead
street lights does not affect the system. The automatic
lamp control system will only be affected when the light
sensor sees a change in lighting lasting longer than
this delay.
If you start your vehicle in a dark garage, the automatic
lamp system will come on immediately. Once you
leave the garage, it will take about 20 seconds for the
automatic lamp system to change to DRL if it is
light outside. During that delay, the instrument panel
cluster may not be as bright as usual. Make sure
the instrument panel brightness control is in the full
bright position. See Instrument Panel Brightness
on page 3-18.
To idle your vehicle with the system off, turn the ignition
on and turn the exterior light switch to the off/on
position. For Canadian vehicles, the transaxle must stay
in PARK (P) for this function or the parking brake
must be set for vehicles with manual transaxles.
As with any vehicle, you should turn on the regular
headlamps when you need them.
