2-47 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 come on when the following
conditions are met::

the ignition is on,

the exterior lamps control is in automatic
headlamp mode,

the automatic transmission is not in PARK (P),

the light sensor determines it is daytime and

the parking brake is released.
When the DRL are on, only your DRL lamps 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 automatic headlamp
system will switch from DRL to the headlamps or the
last chosen headlamp setting that was used.
When you turn the headlamp switch off, the headlamps
will go off, and your DRL lamps will illuminate,
provided it is not dark outside.To idle an automatic transmission equipped vehicle
with the DRL off, set the parking brake. Shifting the
transmission into PARK (P) will also allow you to idle
the vehicle with the DRL off. The DRL will stay off
until you release the parking brake or shift the
transmission out of PARK (P).
This procedure applies only to vehicles first sold in the
United States.
When necessary, you may turn off the Automatic
Headlamp System and the Daytime Running Lamps
(DRL) feature by following these steps. When the
system is turned off, the headlights will not
automatically come on when it becomes dark outside.
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 the system
is off. The system will revert back to the automatic
mode when the ignition is turned off and on again.
3. To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds
(the chime will sound), or turn the ignition off and
on again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-48 Fog Lamps (If Equipped)
If your vehicle has fog lamps, use them for better vision
in foggy or misty conditions.
The fog lamp button is
located on the left side of
the instrument panel.
Your parking lamps and/or low
-beam headlamps must
be on for your fog lamps to work.
Press the button to turn the fog lamps on. Press the
button again to turn them off. An indicator light will
glow in the button when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps in
the dark without turning on your headlamps.
The fog lamps will go off whenever your high
-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps after
you restart the vehicle, you will need to press the fog
lamp button again.
Auxiliary Roof Mounted Lamp Switch
(If Equipped)
If your vehicle has this feature, this switch includes
wiring provisions for a dealer or a qualified service
center to install an auxiliary roof lamp.
This switch is located
on the center of the
instrument panel near
the comfort controls.
When the switch wiring is connected to an auxiliary
roof mounted lamp, pressing the switch will activate
the lamp and illuminate an indicator light near the
switch. Pressing the switch again will turn off the roof
mounted lamp.

To remove the shade from the vehicle:
1. Let the shade go all the way into the holder.
2. Then, grasping the passenger's side shade endcap,
push the shade endcap toward the driver's side of
the vehicle. The endcap should lock in the
compressed position.
3. 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:
1. Make sure the shade slot in the holder faces rearward
with the round surface facing down.
2. Then, hold the shade at an angle and place the shade
holder tab into the slot in the driver's side trim panel.
3. 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.Cargo Tie Downs
There are cargo tie downs in
the rear cargo area that
allow you to strap cargo in
and keep it from moving
inside the vehicle.
When not using the tie downs, flip them down out of
the way.
Convenience Net (If Equipped)
You may have a convenience net in the rear of your
vehicle to help keep small loads, like grocery bags, in
place during sharp turns or quick stops and starts.
The net is not designed for larger, heavier items.
To install the net, attach the hooks to the raised cargo tie
downs. Then, attach the cord loops to the button
retainers in the side trim.
You can unhook the net so that it will lie flat when
you're not using it.

2-60 Luggage Carrier (If Equipped)
If you have the luggage carrier, you can load things on
top of your vehicle.
The luggage carrier has slats and siderails attached to
the roof and crossrails which can be moved back and
forth to help secure cargo. Tie the load to the siderails
or siderail supports.
NOTICE:
Loading cargo that weighs more than
200 lbs. (90.6 kg) on the luggage carrier may
damage your vehicle. When you carry large
things, never let them hang over the rear or the
sides of your vehicle. Load your cargo so that it
rests on the slats and does not scratch or damage
the vehicle. Put the cargo against the siderails
and fasten it securely to the luggage carrier.
Don't exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, see ªLoading Your Vehicleº
in the Index.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.

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.
Ashtrays and Cigarette Lighter
Front Ashtray
The front ashtray is located near the center of the
instrument panel. Pull on the bottom of the ashtray door
to open it.
NOTICE:
If you store paper or other things that burn in
your ashtrays, they could be set on fire by
cigarettes or other smoking materials. That could
cause a fire and possibly damage your vehicle. Do
not store papers and other things that burn in
your ashtrays.
To remove the front ashtray, press the retainer spring
and pull the ashtray toward you. To replace the ashtray,
place the ashtray on the slides at the side of its location
in the instrument panel. Then slide the ashtray back to
its original position.
To use the cigarette lighter, push it in all the way, and let
go. When it's ready, it will pop back out by itself.
NOTICE:
Holding a cigarette lighter in with your hand
while it's heating can make it overload, damaging
the lighter and the heating element. Just push the
lighter all the way in and let go. When it's done,
it will pop back out by itself.
Sun Visors
To block out glare, you can swing down the top and
bottom visors (if equipped). You can also swing the
bottom visor from side
-to-side. Your visors may have
an extension that can be pulled out for additional
glare protection.
