Electric Power Steering (EPS)
The system assists you with steering the
vehicle. If the vehicle is turned off or
if the power steering system becomes
inoperative, you may still steer the
vehicle, but it will require increased
steering effort.
Also, the steering effort becomes heavier
as the vehicle’s speed increases and
becomes lighter as the vehicle’s speed
decreases for better control of the
steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the system
checked by an authorized HYUNDAI
dealer.
CAUTION
• If the Electric Power Steering System
does not operate normally, the
warning light (
) will illuminate
on the instrument cluster. You may
steer the vehicle, but it will require
increased steering efforts. Take your
vehicle to an authorized HYUNDAI
dealer and have the system checked as soon as possible.
• When an abnormality is detected
in the electric power steering
system, to prevent a an accident, the
steering assist function may become
inoperative. At this time, the warning
light turns on or blinks on the cluster.
The steering wheel may become
difficult to control or operate. Have
your vehicle checked immediately,
after moving the vehicle to a safe
area.
Information
The following symptoms may occur during normal vehicle operation: • The steering effort may be high
immediately after placing the ignition switch in the ON position. This happens as the system performs
the EPS system diagnostics. When the
diagnostics are completed, the steering
wheel effort will return to its normal condition.
• When the battery voltage is low, you
might have to put more steering effort.
However, it is a temporary condition so
that it will return to normal condition
after charging the battery.
• A click noise may be heard from the
EPS relay after the ignition switch is in
the ON or LOCK/OFF position.
• Motor noise may be heard when the
vehicle is at a stop or at a low driving speed.
• When you operate the steering wheel
in low temperatures, abnormal noise
may occur. If the temperature rises, the
noise will disappear. This is a normal condition.
• When an error is detected from the EPS, the steering effort assist function
may become inoperative in order to
prevent fatal accidents. Instrument
cluster warning lights may be on or the steering effort may be high. If these
symptoms occur, drive the vehicle to
a safe area as soon as it is safe to do so. Have the system checked by an
authorized HYUNDAI dealer as soon as possible.

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.
