tow GMC YUKON 2002 Owner's Manual

1-3
Manual Cushion Tilt (If Equipped)
If your vehicle has this feature, you can raise or lower
the front of the driver's or passenger's seat with this
lever located at the inside edge of the seat. To raise or
lower the front of the seat, move the lever up or down in
a continuous motion until the cushion reaches the
desired height.
Manual Lumbar Control (If Equipped)
If your vehicle has a lumbar
adjustment, the knob is
located on the outboard side
of the seat cushion.
To increase or decrease support, turn the knob toward
the front or rear of the vehicle. Operating effort can
be reduced if you lean forward slightly while turning
the knob.

1-4 Power Seat(s) (If Equipped)
If your vehicle has a power seat, you can adjust it with
these controls located on the outboard sides of the seats.

Raise or lower the front of the seat cushion by
raising or lowering the forward edge of the
horizontal control.

Move the seat forward or rearward by moving the
whole horizontal control forward or rearward.

Raise or lower the rear of the seat cushion by raising
or lowering the rear edge of the horizontal control.

Moving the whole horizontal control up or down
raises or lowers the entire seat cushion.
If your vehicle has power reclining seats, you can use
the vertical control to adjust the angle of the seatback.
Move the reclining front seatback rearward or forward
by moving the control toward the rear or the front of
the vehicle. See ªReclining Seatbacksº in the Index for
further information.

1-9
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.
On all models with 60/40 split bench seats, you must
insert the center occupant lap belt latch plate into the
loop provided, on the underside of the folded forward
seat cushion, before folding the rear seat back down on
the driver's side.
You may have to adjust the location of the latch plate on
the webbing so that it reaches the loop. Stowing in this
loop will reduce the chances of damaging and soiling
the belt. Remember to remove the latch plate from the
loop before the seat is returned to the passenger position.
On Suburban/Yukon XL insert the two buckles into
the retainer in the seatback, before folding the rear
seat on the driver's side. The buckles will be out of
the way when the seat is folded and will be available
for passengers to use when the seat is returned to the
passenger position. Also, make sure that nothing is
under or in front of the seat and that the head restraints
are completely lowered.
On Tahoe/Yukon models the rear seatbacks may be
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).

1-22
Suburban/Yukon XL: The passenger's side of the
second row 60/40 or rear bucket seats has an easy entry
feature. This makes it easy to get in and out of the third
seat, if your vehicle has one.
To operate the easy entry seat turn the release lever,
located near the back of the seat rearward.
Tilt the seatback toward the front of the vehicle
by pulling the top of the seat forward. When you
do the seat bottom will release. Pull the seat forward
until it stops.
Be sure to return the seat to the passenger position when
finished. Push and pull on the seat to make sure it is
locked in place.Safety Belts: They're for Everyone
This part of the manual tells you how to use safety belts
properly. It also tells you some things you should not do
with safety belts.
And it explains the air bag system.
CAUTION:
Don't let anyone ride where he or she can't wear
a safety belt properly. If you are in a crash and
you're not wearing a safety belt, your injuries
can be much worse. You can hit things inside the
vehicle or be ejected from it. You can be seriously
injured or killed. In the same crash, you might
not be if you are buckled up. Always fasten your
safety belt, and check that your passengers' belts
are fastened properly too.

1-42
How does an air bag restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The air bag supplements the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper body,
stopping the occupant more gradually. But the frontal air
bags would not help you in many types of collisions,
including rollovers, rear impacts, and many side
impacts, primarily because an occupant's motion is not
toward the air bag. Side impact air bags would not help
you in many types of collisions, including frontal or
near frontal collisions, rollovers, and rear impacts,
primarily because an occupant's motion is not toward
those air bags. Air bags should never be regarded as
anything more than a supplement to safety belts, and
then only in moderate to severe frontal or near
-frontal
collisions for the driver's and right front passenger's
frontal air bags, and only in moderate to severe side
collisions for the driver's and right front passenger's
side impact air bags.What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module
-- the
steering wheel hub for the driver's air bag, the
instrument panel for the right front passenger's bag, the
side of the seatback closest to the door for the driver and
right front passenger's side impact air bags
-- will be
hot for a short time. The parts of the bag that come into
contact with you may be warm, but not too hot to touch.
There will be some smoke and dust coming from the
vents in the deflated air bags. Air bag inflation doesn't
prevent the driver from seeing or being able to steer the
vehicle, nor does it stop people from leaving the vehicle.
CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or a door.

1-58
CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child's hip
bones are still so small that the vehicle's regular
safety belt may not remain low on the hip bones,
as it should. Instead, it may settle up around the
child's abdomen. In a crash, the belt would apply
force on a body area that's unprotected by any
bony structure. This alone could cause serious or
fatal injuries. Young children always should be
secured in appropriate child restraints.
Restraint Systems for Children
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed to
restrain or position a child on a continuous flat surface.
Make sure that the infant's head rests toward the center
of the vehicle.

1-77
CAUTION:
Never do this.
Here two children are wearing the same belt. The
belt can't properly spread the impact forces. In a
crash, the two children can be crushed together
and seriously injured. A belt must be used by
only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt is
very close to the child's face or neck?
A:Move the child toward the center of the vehicle, but
be sure that the shoulder belt still is on the child's
shoulder, so that in a crash the child's upper body
would have the restraint that belts provide. If the
child is sitting in a rear seat outside position, see
ªRear Safety Belt Comfort Guidesº in the Index.
If the child is so small that the shoulder belt is still
very close to the child's face or neck, you might
want to place the child in a seat that has a lap belt,
if your vehicle has one.

beginning with Step 1.
You can exit the program mode any time by turning the
ignition to RUN (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.The following is a list of the available
programming options:

All doors lock/Only the driver's door unlocks:
Press the lock side of the power lock switch on the
door panel once and then the unlock side once.

All doors lock/All doors unlock: Press the lock side
of the power lock switch on the door panel once, and
then the unlock side twice.

All doors lock/None of the doors unlock: Press the
lock side of the power lock switch on the door panel
once, and then the unlock side three times.

No doors lock/None of the doors unlock: Press the
lock side of the power lock switch on the door panel
twice. This turns off the automatic lock feature.
For more information, see your dealer.

Passlock
Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
If the engine stalls and the SECURITY message flashes,
wait until the light stops flashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the SECURITY message
comes on, you will be able to restart the engine if you
turn the engine off. However, your Passlock system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock at this
time. You may also want to check the fuse (see ªFuses
and Circuit Breakersº in the Index). See your dealer
for service.
In an emergency, call the GM Roadside Assistance
Center. See ªRoadside Assistanceº in the Index.
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the long
run if you follow these guidelines:

Keep your speed at 55 mph (88 km/h)
or less for the first 500 miles (805 km).

Don't drive at any one speed
-- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.

Ignition Positions
With the key in the ignition switch, you can turn the key
to five different positions.
A (ACCESSORY): This position lets you use things
like the radio, power windows and the windshield
wipers when the engine is off. Push in the key and
turn it toward you.B (LOCK): This position locks your ignition and
transmission. It's a theft
-deterrent feature. You will only
be able to remove your key when the ignition is turned
to LOCK.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break
the key or the ignition switch. If none of this
works, then your vehicle needs service.
C (OFF): This position lets you turn off the engine.
Use OFF if you must have your vehicle in motion
while the engine is off (for example, if your vehicle is
being pushed).
D (RUN): This is the position for driving.
E (START): This position starts your engine.
