THEFT-ALARM SYSTEM
This system helps to protect your vehicle
and valuables. The horn will sound and
the hazard warning lights will blink
continuously if any of the following
occur: - A door is opened without using the remote key or smart key.
- The trunk is opened without using the remote key or smart key.
- The engine hood is opened.
The alarm continues for 30 seconds, then
the system resets. To turn off the alarm,
unlock the doors with the remote key or
smart key.
The Theft Alarm System automatically
sets 30 seconds after you lock the doors
and the trunk. For the system to activate,
you must lock the doors and the trunk
from outside the vehicle with the remote
key or smart key or by pressing the
button on the outside of the door handle
with the smart key in your possession.
The hazard warning lights will blink and
the chime will sound once to indicate the
system is armed.
Once the security system is set, opening
any door, the trunk, or the hood without
using the remote key or smart key will
cause the alarm to activate.
The Theft Alarm System will not set if the
hood, the trunk, or any door is not fully
closed. If the system will not set, check
the hood, the trunk, or the doors are fully
closed.
Do not attempt to alter this system or
add other devices to it. Information
• Do not lock the doors until all
passengers have left the vehicle. If the
remaining passenger leaves the vehicle
when the system is armed, the alarm
will be activated.
• If the vehicle is not disarmed with the
remote key or smart key, open the
doors by using the mechanical key
and place the ignition switch in the
ON position (for remote key) or start
the engine (for smart key) by directly
pressing the ignition switch with the
smart key.
• If the system is disarmed by unlocking
the vehicle, but neither a door or the
trunk is opened within 30 seconds, the
doors will relock and the system will
rearm automatically.

STEERING WHEEL
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.

not toward your face. Make sure you can
see the instrument cluster warning lights
and gauges. After locking the lever, push
the steering wheel both up and down to
be certain it is locked in position. Always
adjust the position of the steering wheel
before driving.

on the lock release lever, readjust the
steering wheel again, and then pull back
up on the release lever to lock the steering
wheel in place.
CAUTION
While adjusting the steering wheel
height, please do not push or pull it
hard since the fixture can be damaged.

MIRRORS
Inside Rearview Mirror
Before driving your vehicle, check to
see that your inside rearview mirror is
properly positioned. Adjust the rearview
mirror so that the view through the rear
window is properly centered.
WARNING
Make sure your line of sight is not
obstructed. Do not place objects in the
rear seat, cargo area, or behind the rear
head restraints which could interfere
with your vision through the rear
window.
WARNING
To prevent serious injury during an
accident or deployment of the air bag,
do not modify the rearview mirror and
do not install a wide mirror.
WARNING
NEVER adjust the mirror while driving.
This may cause loss of vehicle control
resulting in an accident.
NOTICE
When cleaning the mirror, use a paper
towel or similar material dampened
with glass cleaner. Do not spray glass
cleaner directly on the mirror as this
may cause the liquid cleaner to enter
the mirror housing.
Day/night rearview mirror
(if equipped)
ODN8059025LODN8059025L
[A] : Day, [B] : Night
Make this adjustment before you start
driving and while the day/night lever is in
the day position.

Convenient Features5-48
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
Two way communication range distance
between “vehicle” and “garage door
opener” is 100m.
The range may be reduced or increased
a little due to obstacle conditions around
the garage door opener, such as houses or
trees.
Side View Mirrors
ODN8059024ODN8059024
Make sure to adjust the side view mirrors
to your desired position before you begin
driving.
Your vehicle is equipped with both
left-hand and right-hand side view
mirrors. The mirrors can be adjusted
remotely with the remote switch. The
side view mirrors can be folded to help
prevent damage when going through
an automatic car wash or when passing
through a narrow street.
The right side view mirror is convex.
Objects seen in the mirror are closer than
they appear.
Use the inside rear view mirror or look
back directly to determine the actual
distance of other vehicles prior to
changing lanes.
WARNING
Do not adjust or fold the side view
mirrors while driving. This may cause
loss of vehicle control resulting in an
accident.
NOTICE
• Do not scrape ice off the mirror face;
this may damage the surface of the
glass.
• If the mirror is jammed with ice, do
not adjust the mirror by force. Use an
approved spray de-icer (not radiator
antifreeze) spray, or a sponge or soft
cloth with very warm water, or move
the vehicle to a warm place and
allow the ice to melt.
