2004 GMC YUKON DENALI Owners Manual

Flash-to-Pass
This feature lets you 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 in the automatic
position.
To use it, pull the turn signal lever toward you, then
release it.
If your headlamps are in the automatic position or on
low beam, your high-beam headlamps will turn on.
They'll stay on as long as you hold the lever toward you.
The high-beam indicator on the instrument panel
cluster will come on. Release the lever to return to
normal operation.
Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.
8(Mist):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.
N(Delay):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.
6(Low Speed):For steady wiping at low speed,
turn the band away from you to the ®rst solid band past
the delay settings.
1(High Speed):For high-speed wiping, turn the
band further, to the second solid band past the
delay settings.
9(Off):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
L
(Washer Fluid):There is a paddle marked with the
windshield washer symbol at the top of the multifunction
lever. To spray washer ¯uid 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, do not use your washer
until the windshield is warmed. Otherwise the
washer ¯uid can form ice on the windshield,
blocking your vision.
Rear Window Washer/Wiper
This knob is located on the
instrument panel to the left
of the steering wheel.
To turn the rear wiper on, turn the knob to either 1 or 2.
For long delayed wiping, turn the knob to 1. For short
delayed wiping, turn the knob to 2
9(Off):To turn the wiper off, turn the knob to this
symbol.
=(Washer Fluid):To wash the window, press the
knob with this symbol.
The rear window washer uses the same ¯uid bottle as
the windshield washer. However, the rear window
washer will run out of ¯uid before the windshield washer.
If you can wash your windshield but not your rear
windows, check the ¯uid level.

Cruise Control
9
(Off):This position
turns the system off.
R(On):This position activates the system.
+ (Resume/Accelerate):Push the lever to this symbol
to make the vehicle accelerate or resume to a
previously set speed.
T(Set):Press this button to set the speed.
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).
If you apply your brakes, the cruise control will shut off.
{CAUTION:
Cruise control can be dangerous where you
can not drive safely at a steady speed. So, do
not 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. Do not use cruise
control on slippery roads.
3-11

Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not 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 symbol 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 brie¯y from on to
resume/accelerate.
You'll go right back up to your chosen speed and
stay there.
If you 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. If the
accelerator pedal is held longer than 60 seconds,
cruise control will turn off.
3-12

·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 brie¯y to resume/accelerate. Each
time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
·
Press in the 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, brie¯y press
the set button. 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
drivers ®nd this to be too much trouble and don't use
cruise control on steep hills.
Ending Cruise Control
There are four ways to turn off the cruise control:
·Step lightly on the brake pedal,
·move the cruise control switch to off, or
·shift the transmission to NEUTRAL (N).
·If your vehicle has the Stabilitrakžfeature, cruise
control will turn off if road conditions cause
Stabilitrak
žto activate.
·If the accelerator pedal is held for 60 seconds or
longer, cruise control will turn off.
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.
The exterior lamp control has four positions:
9(Off):Turn the knob to this position and release it
to turn off all exterior lamps including the DRLs. To turn
any lamps back on when in the off mode, turn the
knob to the desired lamp mode. To return to the AUTO
mode, turn the knob to the off position and release
it. The off mode will also cancel and the lamps will return
to the AUTO when the vehicle is turned off. This
mode is not available for vehicles ®rst sold in Canada.AUTO:Turn the control to this position to put the
system into automatic headlamp mode. The Daytime
Running Lamps (DRL) will also be activated if it is light
enough outside.
;(Parking Lamps):Turn the control to this position
to turn on the parking lamps, together with the
following:
·Parking Lamps
·Sidemarker Lamps
·Taillamps
·License Plate Lamps
·Instrument Panel Lights
2(Headlamps):Turn the control to this position to
turn on the headlamps, together with the previously
listed lamps and lights.
When the vehicle is turned off and the headlamps are in
AUTO, the headlamps may automatically remain on
for a set time. You can change this delay time using the
DIC. See
Driver Information Center (DIC) on page 3-46.
You can switch your headlamps from low to high-beam
by pushing the turn signal/multifunction lever toward
the instrument panel.
3-14

Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, your automatic headlamp system will
turn on your headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, parking lamps, roof marker 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.
Your vehicle has a light sensor located on the top of the
instrument panel. 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.If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. See ªInstrument
Panel Brightnessº under
Interior Lamps on page 3-17.
Lamps On Reminder
If a door is open, a reminder chime will sound when
your headlamps or parking lamps are manually turned
on and your key is out of the ignition. To turn off
the chime, turn the headlamp switch to off or AUTO and
then back on. In the automatic mode, the headlamps
turn off once the ignition is in LOCK and the headlamps
on at exit delay ends (if enabled in the DIC).
3-15

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
®rst 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 AUTO,
·the transmission is not in PARK (P), and
·the light sensor determines it is daytime.
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.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions. Your parking lamps and/or low-beam
headlamps must be on for your fog lamps to work.
The fog lamp button is
located on the left side of
your instrument panel.
Press the button to turn the fog lamps on while the
headlamps or parking lamps are on. Press the button
again to turn them off. An indicator light will glow
near 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 the 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.
