ODN8A059135
Your vehicle may be equipped with
a Gentex Automatic-Dimming Mirror
with an Integrated HomeLink® Wireless

Automatic-Dimming Night Vision Safety™
(NVS®) Mirror (if equipped)
The NVS® Mirror automatically reduces
glare by monitoring light levels in the
front and the rear of the vehicle. Any
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:
www.gentex.com
Your mirror will automatically dim
upon detecting glare from the vehicles
traveling behind you.
The mirror defaults to the ON position
each time the vehicle is started.
Integrated HomeLink
® Wireless Control
System
The HomeLink® Wireless Control System
can replace 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 programmed 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 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.

WARNING
Before programming HomeLink® to a
garage door opener or gate operator,
make sure people and objects are out
of the way of the device to prevent
potential harm or damage. Do not
use the HomeLink® with any garage
door opener that lacks the safety
stop and reverse features required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an
object - signaling the door to stop and
reverse - does not meet current U.S.
federal safety standards. Using a garage
door opener without these features
increases the risk of serious injury or
death.
Programming HomeLink
®
Please note the following:
• When programming a garage door
opener, it is advised to park the
vehicle outside of the garage.
• It is recommended 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.
• Some vehicles may require the
Engine Start/Stop button to be in the
ACC (or “Accessories”) position for
programming and/or operation of
HomeLink®.
• In the event that there are still
programming difficulties or questions
after following the programming steps
listed below, contact HomeLink® at:
www.homelink.com, www.youtube.
com/HomeLinkGentex or by calling
1-800-355-3515. Programming
To program most devices, follow these

activated device was “open” properly.
Information
Two way communication range distance
between “vehicle” and “garage door
opener” is 100m.
The range may be reduced or increased
a little due to obstacle conditions around
the garage door opener, such as houses or
trees.
