symbol at the top of the multifunction lever. To spray
washer fluid on the windshield, push the paddle.
The wipers will clear the window and then either stop
or return to your preset speed.
CAUTION:

Exterior Lamps
Your parking lamp and headlamp switch is located on
the driver's side of your instrument panel.

manually turn on:

Parking Lamps

Sidemarker Lamps

Taillamps
License Plate Lamps

A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps will flicker on

if this happens.

2-44 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 located on
the top of the instrument panel in the defroster grille.
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
headlamp system when you need it.
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 and your ignition
is in OFF, LOCK or ACCESSORY. To disable the
chime, turn the thumbwheel all the way down. 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 lights are required on all
vehicles first sold in Canada.

sudden maneuver. You or others could be
injured. If you remove the cover, always store it
outside of the vehicle. When you put it back,
always be sure that it is securely reattached.
If you have a cargo security shade, you can use it to
cover items in the cargo area of your vehicle.
To use the shade, pull the shade handle toward the rear
of the vehicle. Latch the shade posts into the retaining
sockets on the cargo area trim panels.
To return the shade to the retracted position, pull up on
the shade handle to release the shade posts from the
retaining sockets. Let the shade move forward to the full
retracted position.To remove the shade from the vehicle, first let the shade
go all the way into the holder. Then, grasping the

toward the driver's side of the vehicle. The endcap
should lock in the compressed position. Lift the shade
up on the passenger's side, swing the shade rearward
and take it out of the vehicle.
To put the shade in the vehicle, first make sure the shade
slot in the holder faces rearward with the round surface
facing down. Then, hold the shade at an angle and place
the shade holder tab into the slot in the driver's side trim
panel. Move the other end of the shade forward and hold
it next to the passenger's side trim panel slot.
Push the button on top of the passenger's side endcap.
This will allow the shade to extend into the trim slot.
Lightly pull on the shade holder to make sure it is
secure. On Suburban/Yukon XL models there are
two slots. The slots furthest forward allow the shade to
be used if the third seat is removed or folded down.

2-57
To prevent damage or loss of cargo as you're leaving,
check now and then to make sure the luggage and cargo
are still securely fastened.
Be sure the cargo is properly loaded.

If small heavy objects are placed on the roof, place
the load in the area over the rear wheels (behind the
rear side door on Suburban/Yukon XL Models).
If you need to, cut a piece of 3/8 inch plywood to fit
inside the crossrails and siderails to spread the load.
If plywood is used, tie it to the siderail supports.

Tie the load to the crossrails or the siderail supports.
Use the crossrails only to keep the load from sliding.
To move the crossrails, pull out on the latch release
handle at each end. Slide the crossrail to the desired
position balancing the force side to side. Push the
release handle back into the latched position and
slide the crossrail back and forth slightly to be sure
the latch snaps securely into place.
If you need to carry long items, move the crossrails
as far apart as they will go. Tie the load to the
crossrails and the siderails or siderail supports. Also
tie the load to the bumpers. Do not tie the load so
tightly that the crossrails or siderails are damaged.

For the purpose of wind noise reduction, locate the
front crossrail approximately 18 to 24 inches
(46 cm to 58 cm) rearward of the front supports.

After moving a crossrail, be sure it is securely locked
into the siderail.
Your vehicle has a Center High
-Mounted
Stoplamp (CHMSL) located above the glass or above
the rear load doors.
If items are loaded on the roof of the vehicle,
care should be taken not to block or damage the
CHMSL unit.

cigarette lighter. Use these outlets to power mobile
telephones or other devices designed to operate with
vehicle electrical systems.
The cigarette lighter is designed to fit only in the

Power outlets are also located in the rear cargo area on
the passenger side and in the rear of the center floor
compartment (if equipped with rear seat audio). To use
the outlets, remove the cover by lifting the pull tab.When not in use, always cover the rear outlet with the
protective cap.
Certain accessory power plugs may not be compatible to
the accessory power outlets and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer for additional information on the
accessory power outlets.
