1-8 Head Restraints
Slide the head restraint up or down so that the top of the
restraint is closest to the top of your ears. This position
reduces the chance of a neck injury in a crash.
Rear Seats
CAUTION:
If a head restraint is not installed on the seatback
or stored in the vehicle properly, it could be
thrown about the vehicle in a crash or sudden
maneuver. People in the vehicle could be injured.
Remove the head restraints only when you need
to fold the seat, and be sure that the head
restraints are stored securely in the space
provided on the folded up seat cushion. When the
seat is returned to the passenger position, be sure
the head restraints are installed properly.
Utility: The rear seat may have a 60/40 split seat which
may be folded down to give you more cargo space. The
rear seatbacks are equipped with rearward folding head
restraints. When the seatback is being folded down, the
head restraint will automatically fold rearward to allow
a flat load floor for cargo or entry to the third row seat
(if equipped).
Suburban/Yukon XL: The second row rear seat of
Suburban/Yukon XL models may have a 60/40 split seat
or rear bucket seats. Either side of the rear seat may be
folded down to give you more cargo space.
On Suburban/Yukon XL models with rear bucket seats,
the head restraints need to be removed in order to fold
the rear seat. To do this, lift the head restraints up until
they stop. Press in the button on the side of the head
restraint guide cap and lift up on the head restraint.
This will need to be repeated on the other cap. The
head restraint can be removed and stored in the space
provided on the folded up seat cushion.

If the rear lock switch is pressed with the rear doors
open, all of the doors will lock five seconds after the
cargo doors are closed.
The power door locks will operate at any time without
the ignition being on.
Operating the power locks may interact with the
theft
-deterrent system (if equipped). See ªContent
Theft
-Deterrentº in the Index.
Programmable Automatic Door Locks
Your vehicle is equipped with an auto lock/unlock
feature which enables you to program your power
door locks.
Your vehicle left the factory programmed to have the
automatic lock feature lock all the doors when the
vehicle speed is greater than 15 mph (24 km/h) for
two seconds, and then unlock all the doors once the key
is removed from the ignition. The following instructions
detail how to program your door locks.To enter the program mode you need to:
1. Beginning with the ignition in OFF, pull back on the
turn signal/multifunction lever all the way toward
you and hold it while you perform the next step.
2. Turn your key to ON and OFF twice. Then, with the
key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock.
3. You are now ready to program the automatic door
locks. Select one of the following four programming
options and follow the instructions. You will have ten
seconds to begin programming. If you exceed the ten
second limit, the locks will automatically lock and
unlock to indicate you have left the program mode.
If this occurs, repeat the procedure beginning with
step 1. You can exit the program mode any time by
turning the ignition to ON (the locks will automatically
lock and unlock to indicate you are leaving the
program mode). If the lock/unlock switches are not
pressed while in the programming mode, the auto
lock/unlock setting will not be modified.

AUTO 4WD: This setting is ideal for use when road
conditions are variable. When driving your vehicle in
AUTO 4WD, the front axle is engaged, but the vehicle's
power is sent only to the rear wheels. When the vehicle
senses a loss of traction, the system will automatically
engage four
-wheel drive. Driving in this mode results in
slightly lower fuel economy than 2HI.
4HI: Use 4HI when you need extra traction, such as
on snowy or icy roads or in most off
-road situations.
This setting also engages your front axle to help drive
your vehicle. This is the best setting to use when
plowing snow.
4LO: This setting also engages your front axle and
delivers extra torque. You may never need 4LO. It sends
maximum power to all four wheels. You might choose
4LO if you are driving off
-road in deep sand, deep mud,
deep snow and climbing or descending steep hills.
CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the transmission
is in PARK (P). You or someone else could be
seriously injured. Be sure to set the parking
brake before placing the transfer case in
NEUTRAL. See ªParking Brakeº in the Index.
NEUTRAL: Shift the vehicle's transfer case to NEUTRAL
only when towing your vehicle. See ªRecreational Vehicle
Towingº or ªTowing Your Vehicleº in the Index for
more information.
Indicator lights in the switches show which setting you are
in. The indicator lights will come on briefly when you turn
on the ignition and one will stay on. If the lights do not
come on, you should take your vehicle to your dealer for
service. An indicator light will flash while shifting the
transfer case. It will remain illuminated when the shift is
complete. If for some reason the transfer case cannot make
a requested shift, it will return to the last chosen setting.

The driver's door has a switch for the passenger
windows as well. Your power windows will work when
the ignition has been turned to ACCESSORY or RUN
or when Retained Accessory Power (RAP) is present.
See ªRetained Accessory Powerº in the Index.
Press the rear of the switch with the power window
symbol on it to lower the window or the front to raise it.
The driver's window also has an express down feature
that allows the window to be lowered without holding
the switch. Press and hold the rear of the window switch
for one second to activate the express down mode.
The express down mode can be canceled at any time
by pressing the opposite side of the switch. To open the
window partway, lightly tap the switch until the window
is at the desired position.
If you have power windows, the power window switch has
a lockout feature. This feature prevents the rear windows
from operating except from the driver's position when the
front driver's side button labeled WINDOW LOCK is
engaged. When the button is not engaged, the rear power
windows will operate again.Horn
To sound the horn, press the center pad on the
steering wheel.
Tilt Wheel (If Equipped)
The tilt steering wheel
allows you to adjust the
steering wheel before
you drive.
You can also raise it to the highest level to give your
legs more room when you enter and exit the vehicle.
To tilt the wheel, hold the steering wheel and pull the
lever located on the lower left of the column. Move the
steering wheel to a comfortable level, then release the
lever to lock the wheel in place.

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.
