CAUTION:
Routing the top strap for a child restraint over or
under the cargo security shade could cause the
shade to come loose and even break. If this
happens, the shade could be thrown about the
vehicle in a collision or sudden maneuver. You or
others could be injured. When anchoring a top
strap to a cargo tiedown, be sure to remove the
cargo security shade from your vehicle. See
ªCargo Security Shadeº in the Index.
Don't use the front set of tie-down brackets. Anchor the
top strap to the rearmost bracket on the same side of the
vehicle as the child restraint. If you need to have an anchor
bracket installed for the center rear seat, you can ask your
dealer to put it in for you. If you want to install the anchor
yourself, your dealer can tell you how to do it.Canadian law requires that child restraints have a top
strap, and that the strap be anchored.
If your child restraint has a top strap, your dealer can
obtain a kit with anchor hardware and installation
instructions specifically designed for this vehicle. The
dealer can then install the anchor for you. This work will
be done for you free of charge. Or, you may install the
anchor yourself using the instructions provided in
the kit.

1-48 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.
3. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

4. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.
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.

1-52 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, even though your
vehicle has Next Generation frontal air bags. 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.
3. 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.

6. To tighten the belt, feed the lap 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.

On the passenger side of the
rear panel door or tailgate,
there is a power lock switch
which can be used to lock or
unlock all of the doors.
On vehicles with panel doors, if the power lock switch is
pressed with the panel doors open, all of the doors will
lock three seconds after the panel doors are closed. If the
panel doors are closed, the vehicle doors will lock when
a power door lock switch is pressed. The theft
-deterrent
system will not re
-arm after the panel doors are closed
unless the power lock switch is pressed first.
Child Security Locks
With this feature, you can
lock the rear side doors so
they can't be opened from
the inside by passengers.
Move the button up to engage the security feature.
Move the button down to return the door locks to
normal operation.
See ªFeature Customizationº in the Index for further
information on turning this feature on and off.

To replace the battery:
1. Insert a small coin, or flathead screwdriver, to
separate the bottom of the transmitter from the top.
2. Remove the battery and replace it with a new one,
making sure the positive (+) side of the battery is
facing down.3. Snap the top and bottom together.
4. Test the operation of the transmitter with your
vehicle. If the transmitter does not work, try
synchronizing the transmitter with the receiver.
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 simultaneously press and hold the LOCK
and UNLOCK buttons on the transmitter for at least
eight seconds. The door locks should cycle and the
parking lamps and headlamps should flash to confirm
synchronization. If this does not happen, you may need
to replace the battery in your transmitter or match the
transmitter to your vehicle. If the locks still do not cycle,
see your dealer for service.

Rear Doors
CAUTION:
It can be dangerous to drive with the tailgate
glass, tailgate or rear doors open because carbon
monoxide (CO) gas can come into your vehicle.
You can't see or smell CO. It can cause
unconsciousness and even death.
If you must drive with the tailgate glass, tailgate
or rear doors open or if electrical wiring or other
cable connections must pass through the seal
between the body and the tailgate glass, tailgate
or rear doors:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting on
VENT. That will force outside air into your
vehicle. See ªComfort Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Tailgate Glass and Tailgate
If your vehicle has a tailgate, you must raise the rear
glass before lowering the tailgate.
To open the glass from the outside, use your key. With
the key in the lock, turn the key clockwise to release the
glass, then lift it up.
To release the glass from the inside, use the electric
tailgate glass release switch on the instrument panel. For
more information, see ªTailgate
-- Electric Glass
Releaseº in the Index.
To open the tailgate, lift up on the handle while pulling
the tailgate toward you.
Close the tailgate before closing the rear glass. After
closing the tailgate, make sure the tailgate is securely
latched by pulling it toward you. After closing the rear
glass, pull up on its handle to make sure it is locked.
