Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to“time out”or quit after several seconds of
transmission. This may not be long enough for
HomeLink
®to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
“time out”in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
“Programming HomeLink
®”procedures (regardless of
where you live), replace Step 3 under“Programming
HomeLink
®”with the following:
Continue to press and hold the HomeLink
®button while
you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
been successfully accepted by HomeLink
®. The
indicator light willash slowly atrst and then rapidly.
Proceed with Step 4 under“Programming HomeLink
®”
to complete.
Using HomeLink®
Press and hold the appropriate HomeLink®button for at
least half of a second. The indicator light will come
on while the signal is being transmitted.
Erasing HomeLink®Buttons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins toash, after 20 seconds.
2. Release both buttons. Do not hold for longer than
30 seconds.
HomeLink
®is now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under“Programming HomeLink
®.”
Individual buttons can not be erased, but they can be
reprogrammed. See“Reprogramming a Single
HomeLink
®Button”next.
Reprogramming a Single HomeLink®
Button
To program a device to HomeLink®using a HomeLink®
button previously trained, follow these steps:
1. Press and hold the desired HomeLink
®button. Do
not release the button.
2. The indicator light will begin toash after
20 seconds. While still holding the HomeLink
®
button, proceed with Step 2 under“Programming
HomeLink®.”

Luggage Carrier
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. (91 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 side rails and fasten it
securely to the luggage carrier. Put the main weight
as far forward as you can.
Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, see″Loading Your Vehicle″.
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
t 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.

If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you signal
a turn, check for burned-out bulbs and a blown fuse.
SeeFuses and Circuit Breakers on page 5-98.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at eachflash of the
turn signal. To turn off the chime, move the turn signal
lever to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low to high beam
or push the lever toward the instrument panel. To return
to low-beam headlamps, pull the multifunction lever
toward you. Then release it.
When the high beams are
on, this light on the
instrument panel cluster
also will be on.
Flash-To-Pass
This feature allows you to use your high-beam
headlamps to signal a driver in front of you that you
want to pass. It works even if your headlamps are off.
To use it, pull the turn signal lever toward you.
If your headlamps are off or on low-beam, your
high-beam headlamps will turn on. They’ll stay on as
long as you hold the lever toward you and the
high-beam indicator on the instrument panel cluster will
come on. Release the lever to turn the high-beam
headlamps off.
Windshield Wipers
8
: Mist
9:Off
You control the windshield wipers by turning the band
with the wiper symbol on it.
For a single wiping cycle, turn the band to mist. Hold it
there until the wipers start, then let go. The wipers
will stop after one wipe. If you want more wipes, hold
the band on mist longer.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain
or snow. Turn the band to choose the delay time. The
closer to the top of the lever, the shorter the delay.

Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you’re
not using cruise, you might hit a button and go
into cruise when you don’t want to. You could
be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press in the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.The cruise light on the instrument panel will illuminate
when the cruise control is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. But you don’t need to
reset it.
Once you’re going about 25 mph (40 km/h) or more, you
can move the cruise control switch from on to
resume/accelerate briefly.
You’ll go right back up to your chosen speed and stay
there.
If you continue to hold the switch at resume/accelerate,
the vehicle will keep going faster until you release
the switch or apply the brake. So unless you want to go
faster, don’t hold the switch at resume/accelerate.

Ending Cruise Control
There are four ways cruise control can be turned off:
•Step lightly on the brake pedal.
•Move the cruise control switch to off.
•Shift the transmission to NEUTRAL (N), or
•If your vehicle has the Stabilitrak®feature, cruise
control will automatically deactivate if road
conditions cause Stabilitrak
®to activate.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Exterior Lamps
The control on the driver’s side of your instrument panel
operates the exterior lamps.
Turn the control clockwise to operate the lamps.
The exterior lamp control has four positions:
9(Off):Turning the control to this position turns off
the Daytime Running Lamps (DRL) and the automatic
headlamps. An indicator light will illuminate when
selected.
3-14
2003 - Yukon/Yukon XL

AUTO (Automatic):Turning the control to this position
puts the system into automatic headlamp mode. An
indicator light will illuminate when this position is
selected.
;(Parking Lamps):Turning the control to this
position turns on the parking lamps, together with the
following:
•Sidemarker Lamps
•Taillamps
•License Plate Lamps
•Instrument Panel Lights
•Roof Marker Lamps (If Equipped)
5(Headlamps):Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
You can switch your headlamps from high to low-beam
by pushing the turn signal/high-beam lever towards
the instrument panel.
A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps willflicker on and
off. Have your headlamp wiring checked right away if
this happens.
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.
