the brake, move the shift button to the
P (Park) position, engage the parking
brake, and place the ignition switch
in the LOCK/OFF position, close all

object that obstructs either light sensor
will degrade the automatic dimming
control feature.
For more information regarding NVS®
mirrors and other applications, please
refer to the Gentex website:

Integrated HomeLink
® Wireless Control
System
The HomeLink® Wireless Control System
can r
eplace up to three hand-held
radio-frequency (RF) transmitters with
a single built-in device. This innovative
feature will learn the radio frequency
codes of most current transmitters to
operate devices such as gate operators,
garage door openers, entry door locks,
security systems, even home lighting.
Both standard and rolling code-equipped
transmitters can be programed by
following the outlined procedures.
Additional HomeLink® information can
be found at: www.homelink.com, www.
youtube.com/HomeLinkGentex or by
calling 1-800-355-3515.
Retain the original transmitter of the
RF device you are programing for use
in other vehicles as well as for future
HomeLink® programing. It is also
suggested that upon the sale of the
vehicle, the programed HomeLink®
buttons be erased for security purposes.
