3-76 Seats and Restraints
If the child restraint has the LATCH
system, seeLower Anchors and
Tethers for Children (LATCH
System)
on page 3‑59for how and
where to install the child restraint
using LATCH. If a child restraint
is secured using a safety belt and
it uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System)
on page 3‑59for top tether anchor locations.
Do not secure a child restraint in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored, or if
the instructions that come with the
child restraint say that the top strap
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached. You will be using the lap-shoulder
belt to secure the child restraint in
this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as
it will go before securing the
forward-facing child restraint.
If you have no other choice but
to install a rear-facing child
restraint in this seat, make sure
the airbag is off once the child
restraint has been installed.
When the airbag off switch
has turned off the right front
passenger frontal airbag, the off
indicator in the airbag off light
should light and stay lit when
you start the vehicle. See Airbag
On-Off Light on page 5‑23.
2. Put the child 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.
4. Push the latch plate into thebuckle until it clicks.
Position the release button so
that the safety belt could be
quickly unbuckled if necessary.

5. Pull the shoulder belt all the wayout of the retractor to set the
lock. When the retractor lock is
set, the belt can be tightened but
not pulled out of the retractor.6. To tighten the belt, push downon the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the belt,
and feed the shoulder belt back
into the retractor. When installing
a forward-facing child restraint,
it may be helpful to use your
knee to push down on the child
restraint as you tighten the belt.
Try to pull the belt out of the
retractor to make sure the
retractor is locked. If the
retractor is not locked,
repeat Steps 5 and 6. 7. If your vehicle does not have
a rear seat and your child
restraint has a top tether, follow
the child restraint manufacturer's
instructions regarding the use
of the top tether. See Lower
Anchors and Tethers for
Children (LATCH System)
on
page 3‑59.
8. Before placing a child in the child restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
safety belt path and attempt to
move it side to side and back
and forth. When the child
restraint is properly installed,
there should be no more than
2.5 cm (1 in) of movement.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.

3-78 Seats and Restraints
If you turned the airbag off with
the switch, turn on the right front
passenger airbag when you remove
the child restraint from the vehicle
unless the person who will be sitting
there is a member of a passenger
airbag risk group. SeeAirbag
On-Off Switch
on page 3‑39for more information, including
important safety information.
Heavy Duty Crew Cab Only
This vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
See Where to Put the Restraint
on
page 3‑57.
A label on the sun visor says,
“Never put a rear-facing child seat
in the front.” This is because the risk
to the rear-facing child is so great,
if the airbag deploys. Never
put a rear-facing child
restraint in the right front passenger
seat. Here is why:
{WARNING
A child in a rear-facing child
restraint can be seriously
injured or killed if the right front
passenger's airbag inflates.
This is because the back of
the rear-facing child restraint
would be very close to the
inflating airbag. Always secure
a rear-facing child restraint in
a rear seat.
If the vehicle does not have a
rear seat that will accommodate
a rear-facing child restraint, a
rear-facing child restraint should
not be installed in the vehicle,
even if the airbag is off. If the child restraint has the LATCH
system, see
Lower Anchors and
Tethers for Children (LATCH
System)
on page 3‑59for how and
where to install the child restraint
using LATCH. If you secure a child
restraint using a safety belt and
it uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System)
on page 3‑59for top tether anchor locations.
Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored,
or if the instructions that come with
the child restraint say that the top
strap must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.

4. Push the latch plate into thebuckle until it clicks.
Make sure the release button is

to unbuckle the safety belt
quickly if necessary.5. Pull the shoulder belt all the wayout of the retractor to set the
lock. When the retractor lock is

a forward-facing child restraint,
it may be helpful to use your

manufacturer's instructions
regarding the use of the top
tether. See Lower Anchors and

Universal Remote System
Programming
This vehicle may have the Universal
Remote System. This system provides a way to
replace up to three remote control
transmitters used to activate
devices such as garage door
openers, security systems, and
home automation devices.
Do not use this system with any
garage door opener that does not
have the stop and reverse feature.
This includes any garage door
opener model manufactured
before April 1, 1982.
Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to
have another person assist with
programming the transmitter.
Be sure to keep the original remote
control transmitter for use in other
vehicles, as well as for future
programming. Only the original
remote control transmitter is needed
for Fixed Code programming.

Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.To program up to three devices:
1. To verify that the garage door
opener is a Fixed Code unit,
remove the battery cover on the
hand-held transmitter supplied
by the manufacturer of the
garage door opener motor.
If there is a row of dip switches
similar to the graphic above,
the garage door opener is a
Fixed Code unit. If you do
not see a row of dip switches,
return to the previous section
for Programming Universal
Home Remote —Rolling Code.
