2000 GMC ENVOY ECU

A booster seat (F) is designed for children who
are about 40 to 60 lbs., or even up to 80 lbs.
(18 to 27 kg, or even up to 36 kg), and about four
to eight years of age. A booster seat is designed to
improve the fit of the vehicle's safety belt system.
Booster seats with shields use lap
-only belts;
however, booster seats without shields use
lap
-shoulder belts. Booster seats can also help
a child to see out the window.When choosing a child restraint, be sure the child
restraint is designed to be used in a vehicle. If it is,
it will have a label saying that it meets federal motor
vehicle safety standards.
Then follow the instructions for the restraint. You may
find these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt system in
your vehicle, but the child also has to be secured within
the restraint to help reduce the chance of personal injury.
The instructions that come with the infant or child
restraint will show you how to do that. Both the owner's
manual and the child restraint instructions are important,
so if either one of these is not available, obtain a
replacement copy from the manufacturer.
Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat. We at
General Motors therefore recommend that you put your
child restraint in a rear seat outside position. Never put a
rear
-facing child restraint in the front passenger seat.
Here's why:

CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because the
back of the rear
-facing child restraint would be
very close to the inflating air bag. Always secure
a rear
-facing child restraint in a rear seat
outside position.
You may secure a forward-facing child restraint
in the right front seat, but before you do, always
move the front passenger seat as far back as it
will go. It's better to secure the child restraint in
a rear seat outside position.
Wherever you install it, be sure to secure the child
restraint properly.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people
in the vehicle. Be sure to properly secure any child
restraint in your vehicle
-- even when no child is in it.
Top Strap
In Canada, the law requires that forward-facing child
restraints have a top strap, and that the strap be
anchored. In the United States, some child restraints
also have a top strap. If your child restraint has a top
strap, it should be anchored.

Anchor brackets for the rear outside seat positions are
located on the floor in the cargo area of your vehicle.
Don't use the rear set of tie
-down brackets. Anchor the
top strap to the closest bracket on the same side of the
vehicle as the child restraint.
Once you have the top strap anchored, you'll be ready to
secure the child restraint itself.
Securing a Child Restraint in a Rear
Outside Seat Position
You'll be using the lap-shoulder belt. See the earlier
part about the top strap if the child restraint has one.
Be sure to follow the instructions that came with the
child restraint. Secure the child in the child restraint
when and as the instructions say.
1. Put the restraint on the seat.
2. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.

5. To tighten the belt, feed the shoulder belt back into
the retractor while you push down on the child
restraint. If you're using a forward
-facing child
restraint, you may find it helpful to use your knee to
push down on the child restraint as you tighten
the belt.6. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety belt
will move freely again and be ready to work for an adult
or larger child passenger.
Center Seat Position
Don't use child restraints in this position. The restraints
won't work properly.

1-45 Securing a Child Restraint in the Right
Front Seat Position
Your vehicle has a right front passenger air bag. Never
put a rear
-facing child restraint in this seat. Here's why:
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because the
back of the rear
-facing child restraint would be
very close to the inflating air bag. Always secure
a rear
-facing child restraint in the rear seat.
Although a rear seat is a safer place, you can secure a
forward
-facing child restraint in the right front seat.
You'll be using the lap
-shoulder belt. See the earlier
part about the top strap if the child restraint has one.
Be sure to follow the instructions that came with the
child restraint. Secure the child in the child restraint
when and as the instructions say.
1. Because your vehicle has a right front passenger air
bag, always move the seat as far back as it will go
before securing a forward
-facing child restraint.
(See ªSeatsº in the Index.)
2. Put the restraint on the seat.

6. To tighten the belt, feed the shoulder belt back into the
retractor while you push down on the child restraint.
You may find it helpful to use your knee to push down
on the child restraint as you tighten the belt.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety belt
will move freely again and be ready to work for an adult
or larger child passenger.
Larger Children
Children who have outgrown child restraints should
wear the vehicle's safety belts.
If you have the choice, a child should sit next to a
window so the child can wear a lap
-shoulder belt and
get the additional restraint a shoulder belt can provide.

2-5 Power Door Locks
The power door lock switch is located on the armrest.
Remove the ignition key and press LOCK to lock all the
doors at once.
To unlock the doors, press the raised area next to the
key symbol.
The switch on each rear door works only that door's lock.
Rear Door Security Lock
With this feature, you can
lock the rear doors so they
can't be opened from the
inside by passengers.
Move the lever up to lock the doors and down to release
the door locks.
Lockout Prevention
This feature stops the power door locks from locking
when the key is in the ignition and a door is open to
protect you from locking your key in the vehicle.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all the doors will lock and
then the driver's door will unlock.

NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.
To replace the battery in the remote keyless entry transmitter:
1. Insert a dime in the slot between the covers of the
transmitter housing near the key ring hole. Remove
the bottom by twisting the dime.
2. Remove and replace the battery with a three
-volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter.
5. Check the operation of the transmitter.
Resynchronization
Resynchronization may be necessary due to the security
method used by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal it has been sent previously.
This prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the LOCK and UNLOCK
buttons on the transmitter at the same time for seven
seconds. The door locks should cycle to confirm
synchronization. If the locks do not cycle, see your
dealer for service.
