includes the following:
•GTurn and Lane Change Signals
•3Headlamp High/Low Beam Changer
•Flash-to-Pass Feature
•NWindshield Wipers
•LWindshield Washer

For information on the exterior lamps, seeExterior
Lamps on page 3-14earlier in this section.
Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn isfinished, the lever will return
automatically.
An arrow on the instrument panel cluster willflash in the
direction of the turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts toflash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If you move the lever all the way up or down, and the
arrowflashes at twice the normal rate, a signal bulb may
be burned out and other drivers may not see your
turn signal.

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.
3-9
2003 - Yukon/Yukon XL

For steady wiping at low speed, turn the band away
from you to thefirst solid band past the delay settings.
For high-speed wiping, turn the band further, to the
second solid band past the delay settings. To stop the
wipers, move the band to off.
Be sure to clear ice and snow from the wiper blades
before using them. If they’re frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.
Windshield Washer
There is a paddle marked with the windshield washer
symbol at the top of the multifunction lever. To
spray washerfluid on the windshield, push the paddle.
The wipers will clear the window and then either
stop or return to your preset speed.
{CAUTION:
In freezing weather, don’t use your washer
until the windshield is warmed. Otherwise the
washer fluid can form ice on the windshield,
blocking your vision.
Rear Window Washer/Wiper
This control is located on
the instrument panel.
To turn the rear wiper on, turn the control to either
1 or 2. For long delayed wiping, turn the control to 1. For
short delayed wiping, turn the control to 2. To turn the
wiper off, turn the control to 0.
To wash the window, press the knob.
The rear window washer uses the samefluid bottle as
the windshield washer. However, the rear window
washer will run out offluid before the windshield washer.
If you can wash your windshield but not your rear
windows, check thefluid level.

Cruise Control
With cruise control, you
can maintain a speed of
about 25 mph (40 km/h) or
more without keeping
your foot on the
accelerator. This can really
help on long trips. Cruise
control does not work
at speeds below about
25 mph (40 km/h).
9:Off
R:On
S:Resume/Accelerate
T:Set
If you apply your brakes, the cruise control will
disengage.
{CAUTION:
•Cruise control can be dangerous where
you can’t drive safely at a steady speed.
So, don’t use your cruise control on
winding roads or in heavy traffic.
•Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
needless wheel spinning, and you could
lose control. Don’t use cruise control on
slippery roads.

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.

Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
•Use the accelerator pedal to get to the higher
speed. Press the set button at the end of the lever,
then release the button and the accelerator
pedal. You’ll now cruise at the higher speed.
•Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch to resume/accelerate briefly. Each
time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
•
Press and hold the set button at the end of the
lever until you reach the lower speed you want, then
release it.
•To slow down in very small amounts, press the set
button briefly. Each time you do this, you’ll go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
driversfind this to be too much trouble and don’t use
cruise control on steep hills.

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.
