ignition GMC YUKON 2000 Owner's Manual

1-6 Heated Front Seats (If Equipped)
If your vehicle has heated
front seats, the ignition
must be in RUN for them
to operate.
The control for the driver's side heated seat is located
on the driver's side door panel. The control for the
passenger's side heated seat is located on the passenger's
side door panel.
To activate the heated seats, press the button once for
the HI heat setting. Press the button again for the LO
heat setting. To turn off the heated seats, press the
button a third time. An indicator light on the button will
illuminate for each heat setting anytime the heated seats
are operating.
The heated front seats will be canceled after the ignition
is turned to OFF. If you still want to use the heated front
seat feature after you restart your vehicle, you will need
to press the heated seat button again.
Reclining Seatbacks
To adjust the front seatback, lift the lever upward.
Release the lever to lock the seatback where you want it.
Lift the lever again upward and the seatback will go to
an upright position.
If your vehicle has power seats with a power recliner,
see ªPower Seatsº in the Index for further information
on how to operate the reclining seatback feature.

1-36 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 two 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.
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the air bags
from working properly?
A:Yes. If you add things that change your vehicle's
frame, bumper system, front end or side sheet metal
or height, they may keep the air bag system from
working properly. Also, the air bag system may not
work properly if you relocate any of the air bag
sensors. If you have any questions about this, you
should contact Customer Assistance before you
modify your vehicle. (The phone numbers and
addresses for Customer Assistance are in Step Two
of the Customer Satisfaction Procedure in this
manual. See ªCustomer Satisfaction Procedureº
in the Index.)

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.

2-3
Your vehicle has one
double
-sided key for the
ignition and all door locks.
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.
Door Locks
CAUTION:
Unlocked doors can be dangerous.
Passengers -- especially children -- can easily
open the doors and fall out. When a door is
locked, the inside handle won't open it.
Outsiders can easily enter through an unlocked
door when you slow down or stop your vehicle.
This may not be so obvious: You increase the
chance of being thrown out of the vehicle in a
crash if the doors aren't locked. Wear safety belts
properly, lock your doors, and you will be far
better off whenever you drive your vehicle.
There are several ways to lock and unlock your vehicle.
Use the keyless entry system (if equipped) or use the
door key.
You can also use your key.

2-5
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.

2-6
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 (this is the factory setting).

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.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.
Move the button forward to engage the security feature.
Move the button rearward to return the door locks to
normal operation.

2-11
To open the driver's side panel door, first open the
passenger's side door. Then, pull the handle on the left
door edge out and pull the door open.
To close the doors, close the driver's side door first.
After securely closing the door, close the passenger's
side door. Make sure both doors are latched securely.
To lock the rear doors from outside the vehicle, put your
key in the lock and turn it clockwise. If you have power
door locks, you can lock the side doors as well as the rear
doors from inside the vehicle. For more information,
see ªPower Door Locksº earlier in this section.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.Your steering wheel will be locked, and so will your
ignition and transmission. Also remember to lock
the doors.
If the key is in the ignition, with any door open, and you
try to lock your doors with the power door locks, the
driver's door will not stay locked. This will help to keep
you from locking your keys in the vehicle.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it's best to lock it up and take your keys.
But what if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?

Put your valuables in a storage area, like your
glove box.

Valuables can be locked in the center floor console.

If your vehicle has a remote keyless entry system,
take the transmitter with you.

Lock all the doors except the driver's.

2-12
Content Theft-Deterrent (If Equipped)
Your vehicle may be equipped with a Content
Theft
-Deterrent alarm system.
With this system, the
SECURITY message will
flash as you open the door
(if your ignition is off).
This message reminds you to activate the theft
-deterrent
system. Here's how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The SECURITY
message should come on and stay on. If using the
remote keyless entry transmitter, the door does not
need to be open.
3. Close all doors. The SECURITY message should go
off after approximately 15 seconds. The alarm is not
armed until the SECURITY message goes off.If a door is opened without the key or the remote keyless
entry transmitter, the alarm will go off. Your vehicle's
headlamps will flash and the horn will sound for about
two minutes, then will turn off to save the battery power.
Remember, the theft
-deterrent system won't activate if
you lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that you
can start your vehicle with the correct ignition key if the
alarm has been set off.
Here's how to avoid setting off the alarm by accident:

If you don't want to activate the theft
-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.

Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any other
way will set off the alarm if the system has been armed.
If you set off the alarm by accident, unlock any door
with the key. You can also turn off the alarm by pressing
UNLOCK on the remote keyless entry transmitter or by
placing the key in the ignition and turning it to START.

2-13 Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for the
SECURITY message to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should but the
vehicle's headlamps flash, check to see if the horn
works. The horn fuse may be blown. To replace the fuse,
see ªFuses and Circuit Breakersº in the Index.
If the alarm does not sound or the vehicle's headlamps
do not flash, the vehicle should be serviced by an
authorized service center.
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.
