2005 GMC YUKON XL Owners Manual

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
cannot 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.

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 briey 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.
3-12

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.
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 briey 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, briey 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
To turn off the cruise control, do any of the following:
Step lightly on the brake pedal.
Move the cruise control switch to off.
Shift the transmission to NEUTRAL (N).
If your vehicle has the StabiliTrak®feature, cruise
control will turn off if road conditions cause
StabiliTrak
®to 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.
Headlamps
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 DRL. 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:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
3-14

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. SeeDriver 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.
Headlamps 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 headlamp
delay ends (if enabled in the DIC).
Daytime Running Lamps (DRL)
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.
3-15

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. SeeInstrument Panel Brightness on page 3-17.
Puddle Lamps
Your vehicle may be equipped with puddle lamps to
help you see the area near the base of the front doors
when it is dark out. The puddle lamps will illuminate
when a door is opened, or when you press the unlock
button on the keyless entry transmitter. The lamps
will time out or turn off once the engine is started.
3-16

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.
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.
Instrument Panel Brightness
The thumbwheel for this feature is located next to the
exterior lamps control.
D(Instrument Panel Lights):Turn the thumbwheel,
located next to the exterior lamps control, up or down to
brighten or dim the instrument panel lights and the radio
display. This will only work if the headlamps or parking
lamps are on.
To turn on the dome lamps, with the vehicle doors
closed, turn the thumbwheel all the way up.
3-17

Dome Lamps
The dome lamps will come on when you open a door
and will slowly dim to off when all doors are closed.
You can also turn the dome lamps on by turning
the thumbwheel, located next to the exterior lamp
control, all the way up. In this position, the dome lamps
will remain on whether a door is opened or closed.
E(Dome Override):Press this button, located below
the exterior lamp control, to turn dome lamps off even
when a door is opened. To return the lamps to automatic
operation, press the button again and it will return to
the out position. In this position, the dome lamps
will come on when you open a door.
Entry Lighting
Your vehicle is equipped with an illuminated entry
feature.
When a door is opened, the dome lamps and puddle
lamps will come on if the dome override button is in the
out position. If the dome override button is pressed
in, the lamps will not come on.
Exit Lighting
Your vehicle is equipped with an illuminated exit feature.
When a door is opened, the dome lamps and puddle
lamps will come on if the dome override button is in the
out position. If the dome override button is pressed
in, the lamps will not come on.
The interior lamps will come on when you remove the
key from the ignition. The lamps will not come on if
the dome override button is pressed in.
Reading Lamps
If your vehicle has reading
lamps, press the button
located next to the lamp to
turn it on or off. The lamps
can be adjusted to point in
the direction you want.
