WARNING
■When programming a garage door or other remote control devices
When programming the HomeLink
® Wireless Control System, you may be
operating a garage door opener or other device. Make sure that people and
objects are out of the way of the garage door or other device to prevent
potential harm or damage.
■ Conforming to federal safety standards
Do not use the HomeLink
® Wireless Control System with a garage door
opener that lacks the safety stop and reverse feature as required by applica-
ble safety standards. A garage door opener which cannot detect an object,
signaling the door to stop and reverse, does not meet these safety stan-
dards. Using a garage door opener without these features increases risk of
serious injury or death. For more information, consult the HomeLink website
at www.homelink.co m or call 1-800-355-3515.
CAUTION
■Hand-held remote (garage door opener remote)
Keep the hand-held remote (garage door opener remote) of the 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 pro-
grammed HomeLink buttons be erased for security purposes. Refer to
“Erasing HomeLink Buttons”. ( →P. 328)
