location. When it is replaced, always be sure that
it is securely reattached.
To use the cargo cover, if equipped: 1. Pull the cover handle toward the rear of the vehicle.
2. Latch the cover posts into the retaining sockets on the cargo area trim panels.
To return the cover to the retracted position: 1. Pull up on the cover handle to release the cover posts from the retaining sockets.
2. Let the cover move forward to the full retracted position. To remove the cover from a regular wheelbase model:
1. Let the cover go all the way into the holder.
2. Then, grasping the driver's side cover end cap, push the cover end cap toward the passenger side
of the vehicle.
3. Swing the cover rearward and take it out of the vehicle.
To put the cover in the vehicle: 1. Make sure the cover slot in the holder faces rearward with the round surface facing down.
2. Then, hold the cover at an angle and place the cover end cap into the slot in the passenger side
trim panel.
3. Move the other end of the cover forward and hold it next to the driver's side trim panel slot.
4. Press the end caps in, to allow the cover to fit into the trim slot.
5. Pull lightly on the cover holder to make sure it is secure.
On extended wheelbase models there are two
cover positions. The slots furthest forward allow
the cover to be used if the third seat is removed
or folded down. The cover can be installed and
removed from either side.

.Headlamps
.Taillamps
.Parking Lamps
.License Plate Lamps
.Instrument Panel Lights
The exterior lamps control has four positions:
O(Off): Turns off the automatic headlamps and
daytime running lamps (DRL). Turning the headlamp
control to the off position again turns the automatic
headlamps or DRL back on.
For vehicles first sold in Canada, the off position only
works for vehicles that are shifted into the P (Park)

4-10

When the headlamps are turned on while the vehicle is
on, the headlamps will turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the vehicle is off, the headlamps will
stay on for 10 minutes before automatically turning off
to prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp
on position to make the headlamps stay on for an
additional 10 minutes.
Headlamps on Reminder
A reminder chime will sound when the headlamps or
parking lamps are manually turned on and the ignition
is off and a door is open. To disable the chime, turn the
light off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles first sold in Canada.The DRL system comes on when the following
conditions are met:
.The ignition is on.
.The exterior lamps control is in AUTO.
.The engine is running.
.The light sensor determines it is daytime.
When the DRL system is on, only the DRL lamps are
on. The taillamps, sidemarker, instrument panel lights,
and other lamps will not be on.
When it begins to get dark, the automatic headlamp
system switches from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release.
For vehicles first sold in Canada, the transmission
must be in the P (Park) position, before the DRL lamps
can be turned off.
4-11

Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system turns on the headlamps at the
normal brightness, along with the taillamps, sidemarker,
parking lamps, and the instrument panel lights.
The radio lights will also be dim.
To turn off the automatic headlamp system, turn
the exterior lamps switch to the off position and
then release it. For vehicles first sold in Canada, the
transmission must be in the P (Park) position, before
the automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel in the defroster grille that regulates
when the automatic headlamps turn on. Do not cover
the sensor or the headlamps will come on whenever
the ignition is on.
The system may also turn on the 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 thatdriving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system is only affected when the light sensor
detects a change in lighting lasting longer than the
delay.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once the
vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is bright enough 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 4‑14.
To idle the vehicle with the automatic headlamp system
off, turn the control to the off position.
The headlamps will also stay on after you exit the
vehicle. This feature can be programmed using the
Driver Information Center (DIC). See DIC Vehicle
Customization (With DIC Buttons) on page 4‑72.
The regular headlamp system can be turned on when
needed.
4-12

Fog Lamps
For vehicles with fog lamps, the control is located next
to the exterior lamps control on the instrument panel, to
the left of the steering column.
The ignition must be in the ON/RUN position for the fog
lamps to come on.
#(Fog Lamps):Press to turn the fog lamps on or off.
A light will come on in the instrument panel 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 along with the fog lamps.
Auxiliary Roof-Mounted Lamp
If the vehicle has this feature, this button includes wiring
provisions for a dealer or a qualified service center to
install an auxiliary roof lamp.
This button is located on
the overhead console.
When the wiring is connected to an auxiliary roof
mounted lamp, pressing the bottom of the button will
activate the lamp and illuminate an indicator light at the
bottom of this button. Pressing the top of the button will
turn off the roof mounted lamp and indicator.
