90 Seats and Restraints
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.
When using the lap-shoulder belt to
secure the child restraint in this
position, follow the instructions that
came with the child restraint and the
following instructions:1. Move the seat as far back as it will go before securing the
forward-facing child restraint.
Move the seat upward or the
seatback to an upright position,
if needed, to get a tight
installation of the child
restraint.
When the passenger sensing
system has turned off the front
outboard passenger frontal
airbag, the off indicator on the
passenger airbag status
indicator should light and stay
lit when the vehicle is started.
See Passenger Airbag Status
Indicator 0110. 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 on
the buckle, away from the child
restraint system, so that the
safety belt could be quickly
unbuckled if necessary.
5. Pull the shoulder belt all theway out 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. 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.
If the airbag is off, the off indicator in
the passenger airbag status
indicator will come on and stay on
when the vehicle is started.
If a child restraint has been installed
and the on indicator is lit, see “If the
On Indicator Is Lit for a Child
Restraint” underPassenger Sensing
System 067.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.

Universal Remote
System
SeeRadio Frequency Statement

Universal Remote System
Programming
If equipped, these buttons are in the
overhead console.
This system can replace up to three
remote control transmitters used to
activate devices such as garage
door openers, security systems, and
home automation devices. These
instructions refer to a garage door
opener, but can be used for other
devices.
Do not use the Universal Remote
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 these instructions completely
before programming the Universal
Remote system. It may help to have
another person assist with the
programming process.
Keep the original hand-held
transmitter for use in other vehicles
as well as for future programming.
Erase the programming when
vehicle ownership is terminated.
See
“Erasing Universal Remote
System Buttons” later in this
section.
To program a garage door opener,
park outside directly in line with and
facing the garage door opener
receiver. Clear all people and
objects near the garage door.
Make sure the hand-held transmitter
has a new battery for quick and
accurate transmission of the
radio-frequency signal.
Programming the Universal
Remote System
For questions or help programming
the Universal Remote system, call
1-800-355-3515 or see
www.homelink.com.
Programming involves
time-sensitive actions, and may time
out causing the procedure to be
repeated.
To program up to three devices:
1. Hold the end of the hand-held transmitter about 3 to 8 cm (1
to 3 in) away from the
Universal Remote system
buttons with the indicator light
in view. The hand-held
transmitter was supplied by the
manufacturer of the garage
door opener receiver.
2. At the same time, press and hold both the hand-held
transmitter button and one of
the three Universal Remote
system buttons to be used to
operate the garage door. Do
not release either button until
