Position the child correctly on the booster cushion
and fasten the seat belt
WARNING
A child seat should never be used in the
front passenger seat of any vehicle with a
front passenger airbag – not even if the
Passenger airbag off symbol near the
rear-view mirror is illuminated (on vehicles
equipped with Occupant Weight Sensor). If
the severity of an accident were to cause the
airbag to inflate, this could lead to serious
injury or death to a child seated in this posi-
tion.
Booster cushions are recommended for chil-
dren who have outgrown convertible seats.
1. Place the booster cushion in the rear seat
of the vehicle.

anchors
G015268
ISOFIX lower child restraint anchors
Lower anchors for ISOFIX-equipped child
seats are located in the rear, outboard seats,
hidden below the backrest cushions. Symbols
on the seat back upholstery mark the anchor
positions (see the illustration).
To access the anchors:1. Put the child restraint in position.
2. Kneel on the child restraint to press down
the seat cushion and locate the anchors by
feel.3. Fasten the attachment on the child
restraint's lower straps to the ISOFIX lower
anchors.
4. Firmly tension the lower child seat straps
according to the manufacturer's instruc-
tions.
NOTE
•The rear seat's center position is not
equipped with ISOFIX lower anchors.
When installing a child restraint in this
position, attach the restraint's top tether
strap (if it is so equipped) to the top
tether anchorage point (see page 46)
and secure the restraint with the vehi-
cle's center seat belt (see page 37).
•Always follow your child seat manufac-
turer's installation instructions, and use
both ISOFIX lower anchors and top
tethers whenever possible.
WARNING
•The ISOFIX lower child restraint
anchors are only intended for use with
child seats positioned in the outboard
seating positions. These anchors are
not certified for use with any child
restraint that is positioned in the center
seating position. When securing a child
restraint in the center seating position,
use only the vehicle's center seat belt.

place.
G026487
Route the strap under the head restraint
WARNING
Be sure to fasten the child tether attachment
correctly to the anchor. If it is not correctly
fastened, the child seat may not be properly
restrained in the event of a collision.
3. Route the top tether strap under the head
restraint and fasten its attachment to the
anchorage.
4. Firmly tension the top tether strap accord-
ing to the child restraint manufacturer's
instructions. Tension the top tether strap
only after the lower anchor straps or the
seat belt have been firmly tensioned.See page 44 for information on securing the
child restraint to ISOFIX lower anchors.
WARNING
•Never route a top tether strap over the
top or around the head restraint. It
should always be routed under the head
restraint.
•Child restraint anchorages are designed
to withstand only those loads imposed
by correctly fitted child restraints. Under
no circumstances are they to be used
for adult seat belts or harnesses. The
anchorages are not able to withstand
excessive forces on them in the event of
collision if full harness seat belts or adult
seat belts are installed to them. An adult
who uses a belt anchored in a child
restraint anchorage runs a great risk of
suffering severe injuries should a colli-
sion occur.
•Do not install rear speakers that require
the removal of the top tether anchors or
interfere with the proper use of the top
tether strap.

Introduction
G030070
The HomeLink1 Wireless Control System pro-
vides a convenient way to replace up to three
hand-held radio-frequency (RF) transmitters
used to activate devices such as gate opera-
tors, garage door openers, entry door locks,
security systems, even home lighting. Addi-
tional HomeLink information can be found on
the Internet at www.homelink.com.
WARNING
•If you use HomeLink to open a garage
door or gate, be sure no one is near the
gate or door while it is in motion.
•When programming a garage door
opener, it is advised to park outside of
the garage.
•Do not use HomeLink with any garage
door opener that lacks safety stop and
reverse features as required by U.S.
federal safety standards (this includes
any garage door opener model manu-
factured before April 1, 1982). A garage
door that cannot detect an object - sig-
naling the door to stop and reverse -
does not meet current U.S. federal
safety standards. For more information,
contact HomeLink at:
www.homelink.com.
Retain the original transmitter of the RF device
you are programming for use in other vehicles
as well as for future HomeLink programming. It
is also suggested that upon the sale of the
vehicle, the programmed HomeLink buttons be
erased for security purposes. Refer to “Erasing
HomeLink Buttons”.
Programming HomeLink
NOTE
Some vehicles may require the ignition
switch to be turned on or to the second
(“accessories”) position for programming
and/or operation of HomeLink. It is also rec-
ommended that a new battery be placed in
the hand-held transmitter of the device
being programmed to HomeLink for quicker
training and accurate transmission of the
radio-frequency signal.
1. Position the end of your hand-held trans-
mitter 1–3 inches (5–14 cm) away from the
HomeLink button you wish to program
while keeping the indicator light in view.
2. Simultaneously press and hold both the
chosen HomeLink and hand-held transmit-
ter buttons until the HomeLink indicator
light changes from a slow to a rapidly blink-
ing light. Now you may release both the
HomeLink and hand-held transmitter but-
tons.

* Option/accessory, for more information, see Introduction.87
NOTE
Some devices may require you to replace
this Programming Step 2 with procedures
noted in the “Gate Operator / Canadian Pro-
gramming” section. If the HomeLink indica-
tor light does not change to a rapidly blink-
ing light after performing these steps, con-
tact HomeLink at www.homelink.com.
3.
Firmly press, hold for five seconds and
release the programmed HomeLink but-
ton up to two separate times to activate the
door. If the door does not activate, press
and hold the just-trained HomeLink button
and observe the indicator light.
•If the indicator light stays on con-
stantly, programming is complete
and your device should activate when
the HomeLink button is pressed and
released.
•If the indicator light blinks rapidly for
two seconds and then turns to a con-
stant light continue with “Program-
ming” steps 4-6 to complete the pro-
gramming of a rolling code equipped
device (most commonly a garage door
opener).
4. At the garage door opener receiver (motor-
head unit) in the garage, locate the “learn”
or “smart” button. This can usually befound where the hanging antenna wire is
attached to the motor-head unit.
5. Firmly press and release the “learn” or
“smart” button. (The name and color of the
button may vary by manufacturer.) There
are 30 seconds to initiate step 6.
6. Return to the vehicle and firmly press, hold
for two seconds and release the pro-
grammed HomeLink button. Repeat the
“press/hold/release” sequence a second
time, and, depending on the brand of the
garage door opener (or other rolling code
equipped device), repeat this sequence a
third time to complete the programming
process.
HomeLink should now activate your rolling
code equipped device.
Gate Operator/Canadian ProgrammingCanadian radio-frequency laws require trans-
mitter signals to “time-out” (or quit) after sev-
eral seconds of transmission – which may not
be long enough for HomeLink to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators are
designed to “time-out” in the same manner.
If you live in Canada or you are having difficul-
ties programming a gate operator or garage
door opener by using the “Programming” pro-cedures, replace “Programming HomeLink”
step 2 with the following:
•Continue to press and hold the HomeLink
button while you press and release -
every two seconds (“cycle”) your hand-
held transmitter until the HomeLink indica-
tor light changes from a slow to a rapidly
blinking light. Now you may release both
the HomeLink and hand-held transmitter
buttons.
Proceed with “Programming” step 3 to com-
plete.
Using HomeLink
To operate, simply press and release the pro-
grammed HomeLink button. Activation will
now occur for the trained device (i.e., garage
door opener, gate operator, security system,
entry door lock, home/office lighting, etc.). For
convenience, the hand-held transmitter of the
device may also be used at any time. In the
event that there are still programming difficul-
ties or questions, contact HomeLink at:
www.homelink.com.

that it is securely locked in the new position
by pressing and/or pulling it.
Removing a head restraintThe front seat head restraints can be removed,
for example, when cleaning the upholstery or if
the front passenger's seat backrest is folded
down to accommodate a long load. To do so:
1. Release the head restraint by pressing the
release button underneath its left side, at
the base of the support.
2. While holding in the release button, press
the locking button at the base of the head
restraint's right support with a screw
driver, etc., and lift the head restraint until
it can be removed completely.
