2002 GMC YUKON key

1-36
The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it's more
likely that the fetus won't be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger's
safety belt properly, see ªDriver Positionº earlier
in this section.
The right front passenger's safety belt works the same
way as the driver's safety belt
-- except for one thing.
If you ever pull the shoulder portion of the belt out all
the way, you will engage the child restraint locking
feature. If this happens, just let the belt go back all the
way and start again.
Air Bag Systems
This part explains the frontal and side impact air
bag systems.
Your vehicle has four air bags
-- a frontal air bag for
the driver, another frontal air bag for the right front
passenger, a side impact air bag for the driver, and
another side impact air bag for the right front passenger.
Frontal air bags are designed to help reduce the risk of
injury from the force of an inflating frontal air bag. But
these air bags must inflate very quickly to do their job
and comply with federal regulations.

1-44 Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
air bag systems. To purchase a service manual, see
ªService and Owner Publicationsº in the Index.
CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag systems. Be sure to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do so.
The air bag systems do not need regular maintenance.
Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:If I add a push bumper or bicycle rack to the
front of my vehicle, will it keep the air bags
from working properly?
A:As long as the push bumper or bicycle rack is
attached to your vehicle so that the vehicle's basic
structure isn't changed, it's not likely to keep the
air bags from working properly in a crash.

Keys
CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be badly injured or even killed.
They could operate the power windows or other
controls or even make the vehicle move. Don't
leave the keys in a vehicle with children.

2-5
Your vehicle has one
double
-sided key for the
ignition and all door locks
as well as the spare tire
hoist lock.
Your vehicle may also have
a key that locks and unlocks
the center floor console
only (if equipped).If you ever lose your keys, your dealer will be able to
assist you with obtaining replacements.
NOTICE:
Your vehicle has a number of new features that
can help prevent theft. But you can have a lot of
trouble getting into your vehicle if you ever lock
your key inside. You may even have to damage
your vehicle to get in. So be sure you have an
extra key.
If you ever do get locked out of your vehicle, call the
GM Roadside Assistance Center. See ªRoadside
Assistanceº in the Index. If your vehicle is equipped
with the OnStar system with an active subscription and
you lock your keys inside the vehicle, OnStar may be
able to send a command to unlock your vehicle. See
ªOnStarº in the Index for more information.

2-6
Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
You can use the keyless entry system (if equipped).
You can also use your key.
To lock the door from
the inside, slide the lever
rearward. To unlock
the door, slide the
lever forward.

options and follow the instructions. You will have
thirty seconds to begin programming. If you exceed
the thirty
-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 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:

2-10 Lockout Prevention
This feature protects you from locking your key in
the vehicle when the key is in the ignition and a door
is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all of the doors will lock
and then the driver's door will unlock.
Child Security Locks (If Equipped)
With this feature, you can lock the rear side doors so
they cannot be opened from the inside by passengers.
Your vehicle may have one of the two child security
lock labels shown.
This feature is located on the inside edge of the
rear doors.
Move the lever forward to engage the security feature.
Move the lever rearward to return the door locks to
normal operation.

2-11
Keyless Entry System (If Equipped)
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 30 feet (9 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
Your keyless entry system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any
interference received, including interference that may
cause undesired operation.
This device complies with RSS
-210 of Industry
Canada. Operation is subject to the following two
conditions: (1) this device may not cause interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation of the device.Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or
a qualified technician for service.
