light GMC YUKON XL 2006 Owner's Manual

Shifting Out of Four-Wheel Low
To shift from Four-Wheel Low to Four-Wheel High,
AUTO 4WD or Two-Wheel High, your vehicle must be
stopped or moving less than 3 mph (5 km/h) with the
transmission in NEUTRAL (N) and the ignition in RUN.
The preferred method for shifting out of Four-Wheel
Low is to have your vehicle moving 1 to 2 mph
(1.6 to 3.2 km/h). Press and release the Four-Wheel
High, AUTO 4WD or Two-Wheel High button. You must
wait for the Four-Wheel High, AUTO 4WD or Two-Wheel
High indicator light to stop ashing and remain on
before shifting your transmission into gear.
Notice:Shifting the transmission into gear before
the Four-Wheel Low indicator light has stopped
ashing could damage the transfer case. To help
avoid damaging your vehicle, always wait for the
Four-Wheel Low indicator light to stop ashing
before shifting the transmission into gear.It is typical for your vehicle to exhibit signicant
engagement noise and bump when shifting between
Four-Wheel Low and Four-Wheel High ranges or from
NEUTRAL with the engine running.
If the Four-Wheel High, AUTO 4WD or Two-Wheel High
switch is pressed when your vehicle is in gear and/or
moving, the Four-Wheel High, AUTO 4WD or Two-Wheel
High indicator light will ash for 30 seconds but will not
complete the shift unless your vehicle is moving less than
3 mph (5 km/h) and the transmission is in NEUTRAL (N).

Shifting into NEUTRAL
To shift the transfer case to NEUTRAL do the following:
1. Make sure the vehicle is parked so that it will
not roll.
2. Set the parking brake. SeeParking Brake on
page 2-31for more information.
3. Start the vehicle or turn the ignition to RUN.
4. Put the transmission in NEUTRAL (N).
5. Shift the transfer case to Two-Wheel High.
6. Simultaneously press and hold the Two-Wheel High
and Four-Wheel Low buttons for 10 seconds.
The NEUTRAL light will come on when the transfer
case shift to NEUTRAL is complete.
7. If the engine is running, verify that the transmission
is in NEUTRAL (N) by shifting the transmission
to REVERSE (R) for one second, then shift
the transmission to DRIVE (D) for one second.
8. Turn the ignition to ACCESSORY, which will turn
the engine off.
9. Place the transmission shift lever in PARK (P).
10. Turn the ignition to LOCK.
Shifting Out of NEUTRAL
To shift out of NEUTRAL do the following:
1. Set the parking brake and apply the regular
brake pedal.
2. Shift the transmission to NEUTRAL (N) and turn
the ignition to RUN with the engine off.
3. Press the button for the desired transfer case
shift position (Two-Wheel High, Four-Wheel High,
AUTO 4WD, or Four-Wheel Low).
After the transfer case has shifted out of
NEUTRAL the NEUTRAL light will go out.
4. Release the parking brake.
Notice:Shifting the transmission into gear
before the Four-Wheel Low indicator light has
stopped ashing could damage the transfer case.
To help avoid damaging your vehicle, always
wait for the Four-Wheel Low indicator light to stop
ashing before shifting the transmission into gear.
5. Start the engine and shift the transmission to
the desired position.
Excessively shifting the transfer case into or out of
the different modes may cause the transfer case to enter
the shift protection mode. This will protect the transfer
case from possible damage and will only allow the
transfer case to respond to one shift per 10 seconds.
The transfer case may stay in this mode for up to
three minutes.

Parking Brake
To set the parking brake, hold the regular brake pedal
down with your right foot. Push down the parking
brake pedal with your left foot.
A chime will activate and the warning light will ash
when the parking brake is applied and the vehicle
is moving at least 3 mph (5 km/h) for at least
three seconds.
To release the parking brake, hold the regular brake
pedal down. Pull the bottom edge of the lever, located
above the parking brake pedal, with the parking
brake symbol, to release the parking brake.If the ignition is on when the parking brake is released,
the brake system warning light will go off.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-60.

Mirror Operation
When turned on, this mirror automatically dims to the
proper level to minimize glare from any headlamps
behind you after dark.
O(On/Off):This is the on/off button for the automatic
dimming feature and compass. Press the far left button,
located below the mirror face, for up to three seconds to
turn the feature on and off. A light on the mirror will
be lit while the feature is turned on.
Compass Operation
Press the on/off button once to turn the compass
on or off.
There is a compass display in the window in the
upper right corner of the mirror face. The compass
displays a maximum of two characters. For example,
“NE” is displayed for north-east.
Compass Calibration
Press and hold the on/off button down for nine seconds
to activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The compass can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the display
reads a direction.
Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. The mirror is
set to zone eight upon leaving the factory. It will be
necessary to adjust the compass to compensate for
compass variance if you live outside zone eight. Under
certain circumstances, such as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account for compass
variance, your compass could give false readings.
2-38

To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the map.
2. Press and hold the on/off button for six seconds.
Release the button when ZONE is displayed.
The number shown is the current zone number.3. Scroll through the zone numbers that appear in
the compass/temperature window on the mirror
by pressing the on/off button. Once you nd your
zone number, release the button. After about
four seconds, the mirror will return to the compass
display, and the new zone number will be set.

interfering with the compass. Such interference may
be caused by a magnetic antenna mount, magnetic
note pad holder, or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,

Universal Home Remote System
Operation
Do not use the Universal Home Remote with any
garage door opener that does not have the “stop
and reverse” feature. This includes any garage door
opener model manufactured before April 1, 1982.
If you have a newer garage door opener with rolling
codes, please be sure to follow Steps 6 through 8
to complete the programming of your Universal
Home Remote Transmitter.
Read the instructions completely before attempting to
program the Universal Home Remote. Because of
the steps involved, it may be helpful to have another
person available to assist you in the programming steps.
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal Home
Remote programming. It is also recommended that
upon the sale of the vehicle, the programmed Universal
Home Remote buttons should be erased for security
purposes. See “Erasing Universal Home Remote
Buttons” later in this section or, for assistance,
seeCustomer Assistance Offices on page 7-4.Be sure that people and objects are clear of the
garage door or gate operator you are programming.
When programming a garage door, it is advised to
park outside of the garage.
It is recommended that a new battery be installed
in your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.
Programming Universal Home Remote
Follow these steps to program up to three channels:
1. Press and hold down the two outside Universal
Home Remote buttons, releasing only when the
Universal Home Remote indicator light begins
to ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
hand-held transmitter to the remaining two Universal
Home Remote buttons.
2. Position the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
Universal Home Remote buttons while keeping
the indicator light in view.
