®Wireless Control Sys-
tem
The HomeLink
®Wireless Control System
can be used to activate remote control
devices such as gate operators, garage
door openers, door locks, home lighting
and security systems.
There are three HomeLink
®buttons on the
mirror, each of which can be programmed
for operation of one desired device. For
details on the device types which can be
operated by this system, consult the HomeLink
®website at: www.homelink.com or call 1-800-355-3515.

®Wire-
less Control System with a gar-
age door opener that lacks the
safety stop and reverse feature
as required by applicable safety
standards. A garage door opener
which cannot detect an object,
signaling the door to stop and
reverse, does not meet these
safety standards. Using a garage
door opener without these fea-
tures increases risk of serious
injury or death. For more infor-
mation, consult the HomeLink
®website at www.homelink.com or
call 1-800-355-3515.

tively.. While the defogger and deicer sys-
tem is in the continuous operation
mode, if the vehicle speed remains at
9 mph (15 km/h) or less for 15 minutes,
