Automatic-Dimming Night Vision Safety™
(NVS®) Mirror (if equipped)
The NVS® Mirror automatically reduces
glar
e 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.

The Idle Stop and Go (ISG) system
automatically and temporarily shuts
down the engine when the vehicle
is stopped and idling to improve fuel
efficiency and reduce exhaust gas
emissions. (i.e. red stop light, stop sign,
and traffic jam).
The engine is automatically started upon
satisfying the starting conditions.
The ISG system is always active, when
the engine is running.
Information
When the engine is automatically started
by the ISG system, some warning
lights (i.e. ABS, ESC, ESC OFF, EPS,
and parking brake warning light) may
illuminate for a few seconds due to the
low battery voltage. However, it does
not indicate a malfunction with the ISG
system.
To Activate the ISG System
Prerequisite for activation
The ISG system operates in the following
situations.
• The driver's seatbelt is fastened
• The driver's door and hood are closed
• The brake vacuum pressure is adequate

Exterior Care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
High-pressure washing
• When using high-pressure washers, make sure to maintain sufficient
distance from the vehicle. Insufficient
clearance or excessive pressure can
lead to component damage or water
penetration.
• Do not spray the camera, sensors or its surrounding area directly with a
high pressure washer. Shock applied
from high pressure water may cause
the device to not operate normally.
• Do not bring the nozzle tip close to boots (rubber or plastic covers) or
connectors as they may be damaged
if they come into contact with high
pressure water.
• Do not use any high-pressure nozzles, which induce either one-direct water
stream or water swirling.
Protecting your vehicle’s finish
Washing
To help protect your vehicle’s finish from
rus
t and deterioration, wash it thoroughly
and frequently at least once a month
with lukewarm or cold water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges
of the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, should be used.
After washing, rinse the vehicle
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see
if they have been affected by water
before getting on the road. If braking
performance is impaired, dry the
brakes by applying them lightly while
maintaining a slow forward speed.
NOTICE
• Do not use strong soap, chemical
detergents or hot water, and do not
wash the vehicle in direct sunlight
or when the body of the vehicle is
warm.
• Be careful when washing the side
windows of your vehicle.
Especially, with high-pressure water,
water may leak through the windows
and wet the interior.
• To prevent damage to the plastic
parts, do not clean with chemical
solvents or strong detergents.
