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.

Information
• Some garage door openers require to
press the programmed button on the
mirror up to three times right after
the programming is just completed to
operate the garage door.
• The indicator (4) is turned ON in
Orange and flashes for about 60
seconds, during the programing mode
and if a programing is not succeeded
within the 60 seconds, the programing
mode will be abort.
HomeLink® should now activate your
rolling code equipped device. Gate operator & Canadian programming
During programming, your handheld
transmitter may automatically stop
transmitting. Continue to press the
Integrated HomeLink® Wireless Control
System button while you press and re-
press (“cycle”) your handheld transmitter
every two seconds until the frequency
signal has been learned. The indicator
light will flash slowly and then rapidly
after several seconds upon successful
training.

The power windows will operate for
approximately 30 seconds after the
ignition switch is placed in the ACC or
LOCK/OFF position. However, if the front
doors are opened, the Power Windows
will not operate even within the 30
second period.
WARNING
To avoid serious injury or death, do not
extend your head, arms or body outside
the windows while driving.

ensure the following:
- Any tools or other loose objects are removed from the engine room area
or hood opening area
- All glove, rags, or other combustible material is removed from the engine
compartment

4. To remove the fuel tank cap (2), turn it counterclockwise. You may hear a
hissing noise as the pressure inside
the tank equalizes.
5. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break the
ice and release the door. Do not pry on the
door. If necessary, spray around the door
with an approved deicer fluid (do not use
radiator antifreeze) or move the vehicle to
a warm place and allow the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn it clockwise until it “clicks” one time.
2. Close the fuel filler door until it is latched securely.
WARNING
Gasoline is highly flammable and
explosive. Failure to follow these
guidelines may result in SERIOUS
INJURY or DEATH:
• Read and follow all warnings posted
at the gas station.
• Before refueling, note the location of
the Emergency Gasoline Shut-Off, if
available, at the gas station.
• Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
• Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire.

05
5-71
• Do not get back into a vehicle
once you have begun refueling.
You can generate a buildup of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapors
causing a fire. If you must re-enter
the vehicle, you should once again
eliminate potentially dangerous
static electricity discharge by
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other gasoline source, with your
bare hand.
• When using an approved portable
fuel container, be sure to place the
container on the ground prior to
refueling. Static electricity discharge
from the container can ignite fuel
vapors causing a fire.
Once refueling has begun, contact
between your bare hand and the
vehicle should be maintained until
the filling is complete.
• Use only approved portable plastic
fuel containers designed to carry and
store gasoline.
• When refueling, always move the
shift button to the P (Park) position,
set the parking brake, and place
the ignition switch to the LOCK/
OFF position. Sparks produced by
electrical components related to the
engine can ignite fuel vapors causing
a fire.
• Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle while at a gas station,
especially during refueling.
• Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.• If a fire breaks out during refueling,
leave the vicinity of the vehicle, and
immediately contact the manager
of the gas station and then contact
the local fire department. Follow any
safety instructions they provide.
• If pressurized fuel sprays out, it can
cover your clothes or skin and thus
subject you to the risk of fire and
burns. Always remove the fuel cap
carefully and slowly. If the cap is
venting fuel or if you hear a hissing
sound, wait until the condition stops
before completely removing the cap.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.
Information
Make sure to refuel your vehicle according
to the “Fuel Requirements” suggested in
the Introduction chapter.
NOTICE
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type of
fuel spilled on painted surfaces may
damage the paint.
• If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can result
in a serious malfunction of the fuel
system or emission control system.
