In case of an emergency
ONE1051019K
In case of emergency such as when the
battery is discharged, the only way to
lock the door(s) is with the mechanical
key from the outside key hole.
Doors without an outside key hole can be
locked as follows:
1. Open the door.
2. Insert the key into the emergency door lock hole and turn the key to the lock position.
3. Close the door securely.
Information
If the electrical power door lock switch
does not operate (ex. dead car battery) and the liftgate is closed, you will not be able to
open the liftgate until power is restored.
WARNING
• The doors should always be fully
closed and locked while the
vehicle is in motion. If the doors
are unlocked, the risk of being
thrown from the vehicle in a crash is
increased.
• Do not pull the inner door handle of
the driver’s or passenger’s door while
the vehicle is moving.
WARNING
Do not leave children or animals
unattended in your vehicle. An enclosed
vehicle can become extremely hot,
causing death or serious injury to
unattended children or animals who
cannot escape the vehicle. Children
might operate features of the vehicle
that could injure them, or they could
encounter other harm, possibly from
someone gaining entry to the vehicle.
WARNING
Always secure your vehicle.
Leaving your vehicle unlocked increases
the potential risk to you or others from
someone hiding in your vehicle.
To secure your vehicle, while
depressing the brake, shift the gear
to the P (Park) position, engage the
parking brake, and press the Start/
Stop button to the OFF position, close
all windows, lock all doors, and always
take the key with you.

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
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.
