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:

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 
provides a convenient way to replace 
up to three hand held radio-frequency 
transmitters used to activate compatible 
devices such as gate operators, garage 
door openers, entry door locks, security 
systems, and home lighting.
NOTICE
HomeLink® operates while the ignition 
switch is in the ACC or ON position 
for safety reasons. It is to prevent 
unintentional security problems from 
happening when the vehicle is parked 
outside the garage.
 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.
For more information, contact 
HomeLink®  at www.homelink.com, or 
call Home-Link customer support at 
1-800-355-3515.
It is also recommended that a new 
battery be replaced in the handheld 
transmitter of the device being trained 
to HomeLink® for quicker training and 
accurate transmission of the radio 
frequency. 1. Programming HomeLink
®
The following steps show how to 
program HomeLink. If you have any 
questions or are having difficulty 
programming your HomeLink buttons,

dealer who sold you the car.

opener, it is advised to park the 
vehicle outside of the garage.

hold for two seconds and release, 
the HomeLink button up to three 
times in a row slowly. Do not press 
the HomeLink button rapidly. As soon 
as you see the garage door start to

until a few seconds after the garage 
door has come to a complete stop, 
regardless of position. At this point, 
programming is complete and your 
device should operate when the 
HomeLink button is pressed and 
released.
3)   Two-Way  Communication 
Pr
ogramming (For select garage door 
openers)
If your garage door opener has the 
‘myQ’ logo on its side, your opener 
likely has Two-Way Communication 
capability. HomeLink has the capability 
to establish Two-Way Communication 
with your garage door opener. HomeLink 
can receive and display “closing” 
or “opening” status messages from 
compatible garage door openers. At 
any time, Home-Link can also recall 
and display the last recorded status 
communicated by the garage door 
opener to indicate your garage door 
being “closed” or “opened”.
To check if your garage door opener is 
compatible with this feature, refer to 
www.homelink.com/compatible/Two-
way-Communication. If your garage 
door opener has this functionality, AND 
the Two-Way Communication indicators 
(4), (6) in the mirror appear while the 
garage door is opening/closing, then 
no further steps are needed. Two-Way 
Communication Programming is already 
complete. However, if your garage door 
opener has this functionality, AND the 
Two-Way Communication indicators (4), 
(6) in the mirror DO NOT appear while 
the garage door is opening/closing, use 
the following instructions to enable this 
functionality.
1.
 In your v
ehicle, press and hold the 
programmed HomeLink button for 2 
seconds, then release. Confirm that 
the garage door is moving. AFTER it 
stops, you will have one minute to 
complete the following steps:

2. On your garage door opener in your 
garage, locate the “Learn” button 
(usually near where the hanging 
antenna wire is attached to the garage 
door opener). If there is difficulty 
locating this button, reference the 
device’s owner’s manual.
3.
 Press and r
elease the “Learn” button.
4.
 A light on y
our garage door opener 
may flash, and your Two-Way 
Communication indicators (4), (6) in 
your vehicle may flash, confirming 
completion of the process.
5.
 Re
turn to the vehicle and firmly 
press and release the programmed 
HomeLink button to activate 
your garage door. The Two-Way 
Communication indicators (4), (6) 
flash in orange when the door is 
moving. Do not make any additional 
button presses until AFTER the garage 
door has come to a complete stop.
6.
 Your T
wo-Way Communication 
programming is now complete.
 Information
If your garage door opener has Two-
Way Communication functionality, 
it is possible for HomeLink to stop 
functioning the garage door shortly 
after initial programming, IF the Two-
Way Communication Programming 
wasn’t properly completed. This 
usually happens after the first 10 times 
a programmed HomeLink button is 
pressed. If you experience this, completing 
the “Programming a New HomeLink 
Button” and “Two-Way Communication 
Programming” will restore door 
operation.
4) Canadian Pr ogramming
Canadian radio-frequency laws require 
transmitter remote signals to “time-
out” (or quit) after a couple seconds of 
transmission, which may not be long 
enough for HomeLink to pick up the signal 
during programming.
If you live in Canada or you are having 
difficulties programming a gate operator 
or garage door opener by using the 
programming procedures, replace 
“Programming a New HomeLink Button” 
step 3 with the following:
While the HomeLink indicator light (7) is 
flashing orange, press and release (“cycle”) 
your device’s handheld remote every two 
seconds until the HomeLink indicator light 
(7) changes from orange to green. You may 
now release the hand-held remote button. 
Then proceed with “Programming a New 
HomeLink Button” step 4.
