Automatic Headlamp System When it is dark enough outside, your Automatic Headlamp System will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will also be dim. Your vehicle is equipped with a light sensor on the top of the instrument panel under the defroster grill, so be sure it is not covered which will cause the system to be on whenever the ignition is on. 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 DRL and the Automatic Headlamp System so that driving under bridges or bright overhead street lights does not affect the system. The DRL and Automatic Headlamp Systems 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 headlamp system will come on immediately. Once you leave the garage, it will take approximately one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness control is in the full bright position. See "Instrument Panel Brightness Control" under Interior Lamps on page 3-16. To idle your vehicle with the system off, set the parking brake while the ignition is off. Then start the vehicle. The system will stay off until you release the parking brake. As with any vehicle, you should turn on the regular headlamps when you need them. Headlamps Off in PARK (P) To turn the headlamps off when it is dark outside, turn the exterior lamps control to the parking lamp position. In this position, the parking lamps, sidemarker lamps, taillamps, license plate lamps and instrument panel lights will be on, but the headlamps will be off. To turn on the headlamps along with the other lamps when it is dark outside, turn the exterior lamps control to the AUTO or headlamp position. 3-15

Automatic Headlamp System
When it is dark enough outside, your Automatic
Headlamp System will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the
top of the instrument panel under the defroster grill, so
be sure it is not covered which will cause the system
to be on whenever the ignition is on.
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 DRL and the Automatic
Headlamp System so that driving under bridges or bright
overhead street lights does not affect the system. The
DRL and Automatic Headlamp Systems 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
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
control is in the full bright position. See “Instrument
Panel Brightness Control” under
Interior Lamps
on page 3-16
.
To idle your vehicle with the system off, set the parking
brake while the ignition is off. Then start the vehicle.
The system will stay off until you release the parking
brake.
As with any vehicle, you should turn on the regular
headlamps when you need them.
Headlamps Off in PARK (P)
To turn the headlamps off when it is dark outside, turn
the exterior lamps control to the parking lamp position.
In this position, the parking lamps, sidemarker lamps,
taillamps, license plate lamps and instrument panel
lights will be on, but the headlamps will be off.
To turn on the headlamps along with the other lamps
when it is dark outside, turn the exterior lamps control to
the AUTO or headlamp position.
