Rear Occupant Alert (ROA)
System
The Rear Occupant Alert (ROA) system
is provided to help prevent exiting the
vehicle with the rear passenger left in the
vehicle. When you open the front door
after opening and closing the rear door
and turning off the engine, the “Check
rear seats” warning message appears on
the cluster.

CAUTION
• The system does not actually detect
objects or people in the rear seat. By
using a rear door opened and closed
history, the system indicates that
there may be something in the rear
seat.
• The rear door opened and closed
history can be initialized only when
you turn off the engine normally, get
off the vehicle and lock the door with
the remote control key. Therefore,
there could be alarms even though
the back doors are locked.
ex) When you get in and drive your vehicle without locking the doors
after the alarm sounds, there could
be the alarm sounds if you turn off
the engine and open the driver’s seat
door.
WARNING
It does not use the actual sensors but it
provides the alarm sounds by checking
the rear door lock/unlock status as a
reminder.

Electrochromic Mirror (ECM) (if equipped)
ODN8059023L
The electric rearview mirror automatically
controls the glare from the headlamp of
the vehicle behind you in nighttime or low
light driving conditions.
When the engine is running, the glare is
automatically controlled by the sensor
mounted in the rearview mirror. The
sensor detects the light level around the
vehicle, and automatically adjusts to
control the headlamp glare from vehicles
behind you.
Whenever the shift button is placed in R
(Reverse), the mirror will automatically
go to the brightest setting in order to
improve the driver’s view behind the
vehicle. Electrochromic mirror (ECM) with
HomeLink® system (if equipped)ODN8A059135
Your vehicle may be equipped with
a Gentex Automatic-Dimming Mirror
with an Integrated HomeLink® Wireless
Control System.
During nighttime driving, this feature
will automatically detect and reduce
rearview mirror glare. The HomeLink®
Universal Transceiver allows you to
activate your garage door(s), electric
gate, home lighting, etc.

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
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
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.

reservoir.
WARNING
When the outside temperature is below
freezing, ALWAYS warm the windshield
using the defroster to help prevent
the washer fluid from freezing on the
windshield and obscuring your vision
which could result in an accident and
serious injury or death.
NOTICE
• To prevent possible damage to the
washer pump, do not operate the
washer when the fluid reservoir is
empty.
• To prevent possible damage to the
wipers or windshield, do not operate
the wipers when the windshield is
dry.
• To prevent damage to the wiper
arms and other components, do
not attempt to move the wipers
manually.

(if eQUippeD)
Reverse Parking Collision-Avoidance
Assist (PCA) is a supplemental system
that can warn the driver or apply braking
force to reduce the possibility of collision
with pedestrians when the vehicle is
reversing.
WARNING
• Always look around your vehicle to make sure there are no objects or
pedestrian before moving the vehicle
in any direction to prevent a collision.
• Do not solely rely on Reverse Parking Collision-Avoidance Assist system.
The system might not assist the
driver leading to pedestrian injury or
vehicle damage.
• Be aware that some objects may not be visible on the screen or be
detected by the rear ultrasonic
sensors, due to the objects’ distance,
size or material, all of which can limit
the effectiveness of the sensors.
System Setting and Operation
System setting
Parking Collision-Avoidance Assist-
Reverse (PCA-R) can be activated from
the Settings menu in the LCD display or
infotainment system display by following
the procedure below.
1. Set the Engine Start/Stop button to
the ON or START position.
2. Select ‘User Settings → Driver Assistance → Parking Safety → Active
Assist / Warning Only / Off’ in the
LCD display or infotainment system
display.
- The system is ready for operation when 'Active Assist' is selected. In
the event of an imminent collision
with a pedestrian or an object, the
system warns the driver or applies
braking force to help avoid the collision.
- The system is ready for operation when 'Warning Only' is selected. In
the event of an imminent collision
with a pedestrian, the system warns
the driver but does not assist in
braking.
- The system deactivates when 'Off' is selected.

Operating conditions
Reverse Parking Collision-Avoidance
Assist system enters the ready status,
when 'Active Assist' or 'Warning Only' is
selected in the AVN system screen and
the following conditions are satisfied:
• The trunk is closed
• The shift lever is in R (Reverse)
• Vehicle speed is below 10 km/h (6 mph)
• System components such as the rear
view camera and the rear ultrasonic
sensors are in normal conditions
The driver needs to select 'Active Assist'
on the LCD display or infotainment
system display for collision-avoidance
assist.
The solid lines behind the vehicle in the
cluster LCD display indicates that the
system is ready to assist the driver.
Note that the system assists the driver
only once. The driver has to shift the gear
to R (Reverse) from another gear position
to reactivate the system.
The performance of Reverse Parking
Collision-Avoidance Assist system may
vary under certain conditions. If the
vehicle speed exceeds 3 km/h (2 mph),
the system can assist only pedestrian
collision avoidance.
As always, be careful when backing
up your vehicle and be aware of your
surroundings.
