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 head. This position
reduces the chance of a neck injury in a crash.On some models, the head restraints tilt forward and
rearward also.
The rear seat head restraints in your vehicle may be
adjustable. They work the same as the front seat head
restraints, except they do not tilt forward or rearward.
Rear Seats
60/40 Split Bench Seat
Tahoe/Yukon: The rear seat may have a 60/40 split
seat which may be folded down to give you more
cargo space.
Suburban/Yukon XL: The second row rear seat of
Suburban/Yukon XL models may have a 60/40 split
seat. Either side of the rear seat may be folded down
to provide more cargo space.

1-11
Make sure that the buckles on the driver's side seatback
are accessible to the outboard and center occupant and
are not under the seat cushions.
On Tahoe/Yukon models make sure the head restraints
are returned to the upright position.
Bucket Seats (Suburban/Yukon XL
Second Row)
If your vehicle has bucket seats, the seatbacks can be
reclined and the seats can be folded to give you more
cargo room.
Reclining the Seatbacks
On the Suburban/Yukon XL models with bucket seats,
the seatbacks can be reclined. To adjust the seatback do
the following:
1. Pull forward the lever located at the base of the back.
2. Release the lever to lock the seatback where you
want it. If you pull the lever without pushing on the
seatback, the seatback will go to an upright position.Folding the Seatbacks
CAUTION:
If the seatback isn't locked, it could move forward
in a sudden stop or crash. That could cause injury
to the person sitting there. Always press rearward
on the seatback to be sure it is locked.
The seatbacks on the bucket seats may be folded
forward to give you more cargo space.
In order to fold the back of a bucket seat into a
horizontal load floor, the back must be in its upright
position, and not reclined.

Tahoe/Suburban/Yukon/Yukon XL models with rear
seats: A child restraint with a top strap should only be
used in the second or third row. Don't use a child
restraint with a top strap in the front seat because there's
no place to anchor the top strap.
An anchor loop bracket for a top strap is located at the
bottom rear of the seat cushion for each seating position
in the second row, and for the center seating position in
the third row.

2-26 Tow/Haul Mode Selector Button
Your vehicle is equipped with a tow/haul mode. The
selector button is located on the end of the column shift
lever. You can use this feature to assist when towing or
hauling a heavy load. See ªTow/Haul Modeº in the
Index for more information.
The tow/haul mode also interacts with the Autoride

feature, if your vehicle is so equipped, to enhance the
ride when trailering or with a loaded vehicle. See
ªAutoride
º in the Index.
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.
If the ignition is on, the brake system warning light
will flash. A chime will activate 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, marked BRAKE
RELEASE, to release the parking brake.

2-33
Automatic Level Control
The automatic level control rear suspension is available
on C/K 1500 vehicles and comes as a part of the
Autoride
suspension.
This type of level control is fully automatic and will
provide a better leveled riding position as well as better
handling under a variety of passenger and loading
conditions. An air compressor connected to the rear
shocks will raise or lower the rear of the vehicle to
maintain proper vehicle height. The system is activated
when the ignition key is turned to RUN and will
automatically adjust vehicle height thereafter. The
system may exhaust (lower vehicle height) for up to ten
minutes after the ignition key has been turned to OFF.
You may hear the air compressor operating when the
height is being adjusted.
If a self
-equalizing hitch is being used, it is
recommended to allow the shocks to inflate, thereby
leveling the vehicle prior to adjusting the hitch.
Autoride
(If Equipped)
The Autoride feature will provide a superior vehicle
ride and handling under a variety of passenger and
loading conditions.
The system is fully automatic and uses a computer
controller to continuously monitor vehicle speed, wheel
to body position, lift/drive and steering position of the
vehicle. The controller then sends signals to each shock
absorber to independently adjust the damping level to
provide the optimum vehicle ride.
Autoride also interacts with the tow/haul switch that,
when engaged, will provide additional control of the
shock absorbers. This additional control results in better
ride and handling characteristics when the vehicle is
loaded or towing a trailer. See ªTow/Haul Modeº in the
Index for more information.
Locking Rear Axle (If Equipped)
If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice, sand
or gravel. It works like a standard axle most of the time,
but when one of the rear wheels has no traction and the
other does, this feature will allow the wheel with
traction to move the vehicle.

2-35
You can choose among four driving settings:
2HI: This setting is used for driving in most street
and highway situations. Your front axle is not engaged
in two
-wheel drive. This setting also provides the best
fuel economy.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.

2-47 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 first 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 automatic
headlamp mode,

the automatic transmission is not in PARK (P),

the light sensor determines it is daytime and

the parking brake is released.
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 or the
last chosen headlamp setting that was used.
When you turn the headlamp switch off, the headlamps
will go off, and your DRL lamps will illuminate,
provided it is not dark outside.To idle an automatic transmission equipped vehicle
with the DRL off, set the parking brake. Shifting the
transmission into PARK (P) will also allow you to idle
the vehicle with the DRL off. The DRL will stay off
until you release the parking brake or shift the
transmission out of PARK (P).
This procedure applies only to vehicles first sold in the
United States.
When necessary, you may turn off the Automatic
Headlamp System and the Daytime Running Lamps
(DRL) feature by following these steps. When the
system is turned off, the headlights will not
automatically come on when it becomes dark outside.
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you the system
is off. The system will revert back to the automatic
mode when the ignition is turned off and on again.
3. To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds
(the chime will sound), or turn the ignition off and
on again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
