sion, unsecured cargo could cause per-
sonal injury.

age the top tether strap during a colli-
sion. If the cargo cover contacts the top
tether strap when it is attached to the
top tether anchor, remove the cargo
cover from the vehicle or secure it on the
cargo floor below its attachment loca-
tion. If the cargo cover is not removed, it
may damage the top tether strap during
a collision. Your child could be seriously
injured or killed in a collision if the child
restraint top tether strap is damaged.

POWER WINDOWS
WARNING
∙ Make sure that all passengers have their hands, etc., inside the vehicle while it is in
motion and before closing the windows.
Use the window lock switch to prevent
unexpected use of the power windows.
∙ To help avoid risk of injury or death through unintended operation of the ve-
hicle and/or its systems, including en-
trapment in windows or inadvertent door
lock activation, do not leave children,
people who require the assistance of oth-
ers or pets unattended in your vehicle.
Additionally, the temperature inside a
closed vehicle on a warm day can quickly
become high enough to cause a signifi-
cant risk of injury or death to people and
pets.
The power windows operate when the igni-
tion switch is placed in the ON position or for
a period of time after the ignition switch is
placed in the OFF position. If the driver’s or
passenger’s door is opened during this period
of time, the power to the windows is can-
celed.

The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-held
transmitters into one built-in device.
HomeLink® Universal Transceiver:∙ Will operate most radio frequency de- vices such as garage doors, gates, home
and office lighting, entry door locks and
security systems.
∙ Is powered by your vehicle’s battery. No separate batteries are required. If the ve-
hicle’s battery is discharged or is discon-
nected, HomeLink® will retain all pro-
gramming.
When the HomeLink® Universal Transceiver
is programmed, retain the original transmit-
ter for future programming procedures (Ex-
ample: new vehicle purchases). Upon sale of
the vehicle, the programmed HomeLink®
Universal Transceiver buttons should be
erased for security purposes. For additional
information, refer to “Programming
HomeLink®” in this section.WARNING
∙ Your vehicle’s engine should be turned off while programming the HomeLink® Uni-
versal Transceiver. For additional infor-
mation, refer to “Push-button ignition
switch” in the “Starting and driving” sec-
tion of this manual. Do not breathe ex-
haust gases; they contain colorless and
odorless carbon monoxide. Carbon mon-
oxide is dangerous. It can cause uncon-
sciousness or death.
∙ Do not use the HomeLink® Universal Transceiver with any garage door opener
that lacks safety stop and reverse fea-
tures as required by federal safety stan-
dards. (These standards became effec-
tive for opener models manufactured
after April 1, 1982.) A garage door
opener which cannot detect an object in
the path of a closing garage door and
then automatically stop and reverse does
not meet current federal safety stan-
dards. Using a garage door opener with-
out these features increases the risk of
serious injury or death. ∙ During the programming procedure your
garage door or security gate will open
and close (if the transmitter is within
range). Make sure that people or objects
are clear of the garage door, gate, etc.,
that you are programming.
PROGRAMMING HOMELINK®
If you have any questions or are having diffi-
culty programming your HomeLink® but-
tons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-
3515.
NOTE:
Place the ignition switch in the ON position
(without starting the engine) when pro-
gramming HomeLink®. It is also recom-
mended that a new battery be placed in the
hand-held transmitter of the device being
programmed to HomeLink® for quicker pro-
gramming and accurate transmission of the
radio frequency.
