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 radio speaker grill.
Be sure it is not covered or the system will be on
whenever the ignition is on.
The system may also turn on your headlamps 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 Daytime Running
Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting longer
than the delay.To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
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.
You may be able to turn off your automatic headlamp
system. See ªDaytime Running Lamps (DRL)º later in
this section for more information
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on, the driver's door
is opened and your ignition is in OFF, LOCK or
ACCESSORY. To turn the chime off, turn the control all
the way to the left or turn the instrument panel
brightness thumbwheel down to the fully dimmed
position. In the automatic mode, the headlamps turn off
once the ignition key is in OFF.

Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.
The DRL system will make your headlamps come
on at reduced brightness when the following conditions
are met:

The ignition is on,

the exterior lamp control is in OFF,

the sensor detects daytime light,

an automatic transmission is not in PARK (P), and

the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
The instrument panel won't be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular
headlamps.The DRL system on some vehicles may turn off
temporarily while the turn signals are activated.
To idle an automatic transmission vehicle with the DRL
off, put the transmission in PARK (P). To idle a manual
transmission vehicle with the DRL off, set the parking
brake. The DRL will stay off until you shift out of
PARK (P) or release the parking brake.
The following does not apply to vehicles sold in Canada.
When necessary, you may turn off the automatic
headlamp system and the Daytime Running Lamps
(DRL) feature by following the steps below:
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you that the
system is off. The system will revert back to the
automatic on mode when the ignition is turned to
OFF and then to RUN again.
3. To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds
(a chime will sound), or turn the ignition to OFF and
then to RUN again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

button again to turn them off. A light will glow in the

lifted and released, the lamps will stay on for a short
period of time and will turn off automatically. If you use
your keyless entry transmitter (if equipped) to unlock
your vehicle, the interior lamps will come on for a short
time whether or not the DOME OVERRIDE button is in
the out position.

Exit Lighting
With exit lighting, the interior lamps will come on when

You can also turn the lamps on and off by pressing the
button near each lamp.
Dome Lamps

Electrochromic Day/Night Inside Rearview
Mirror (If Equipped)
This mirror automatically changes to reduce glare from
headlamps behind you. A photocell on the back of the
mirror senses when it is becoming dark outside. Another
photocell built into the mirror surface senses when
headlamps are behind you.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare (this change may take a
few seconds). The mirror will return to its clear daytime
state when the glare is reduced. The mirror will also
return to its clear daytime state when the vehicle is put
into REVERSE (R).
Press the AUTO button at the base of the mirror to turn
on the automatic feature. The button has an indicator
light to show it is on. Press the OFF button to turn the
automatic feature off.

Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary switching from the night back to
the day position. This delay prevents rapid changing of
the mirror as you drive under lights and through traffic.
Cleaning the Photocells
Use a cotton swab and glass cleaner to clean the
photocells when necessary.
Outside Manual Adjust Mirror
Adjust your outside mirrors so you can just see the side
of your vehicle.
You can fold them before entering a car wash. Pull the
mirrors in toward the vehicle. Push the mirrors back out
when finished.
Power Remote Control Rearview Mirrors

the driver's or passenger's mirror, then use the arrows
located on the four
-way control pad to move the mirror
in the direction you want the mirror to go.

for cassettes or compact discs and a coinholder.
Convenience Net (If Equipped)
You may have a convenience net in the rear of your vehicle to
help keep small items, like gloves and light clothing, in place
during sharp turns or quick stops and starts.
The net is not designed to retain these items during
off
-road use. The net is not for larger, heavier items.
Attach the upper loops to the retainers on either side of
the endgate opening (the label should be in the upper
passenger side corner, visible from the rear of vehicle).
Attach the lower hooks to the rear cargo tie downs on
the floor.
