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.

Tilt Steering / Telescope Steering
When adjusting the steering wheel to a
comfortable position, adjust the steering
wheel so that it points toward your chest,
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.
WARNING
NEVER adjust the steering wheel while
driving. This may cause loss of vehicle
control resulting in an accident.
ODN8059021
To adjust the steering wheel angle and
height:
1. Pull down the lock-release lever (1).
2. Adjust the steering wheel to the
desired angle (2) and distance
forward/back (3).
3. Pull up the lock-release lever to lock
the steering wheel in place.
Information
Sometimes the lock release lever may not
engage completely. This may occur when
the gears of the locking mechanism do not
completely mesh. If this occurs, pull down
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.

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.

How to Use
Solar roof operates automatically when
it gets exposed to the sun regardless
of the vehicle’s start-up. If the vehicle
turns off while activating the solar roof,
it stops around 5 minutes and starts to
re-operate.
ODN8H059313[A] : Solar cell
Battery Charging Amount
The solar roof charges the starting
battery and high-voltage battery by
generating electricity with the sunlight.
The amount of electricity produced by
the solar roof varies according to sunlight
intensity and temperature and stronger
sunlight and lower temperature produce
more electricity.
Information
• The solar roof generates more
electricity with stronger sunlight
but the intensity of sunlight may be
different from feeling thermometer.
• The solar cell installed in the solar
roof can produce more electricitywhile
driving due to cooling occurred by
wind than parking status since its
generating efficiency increases in lower
temperature.
Solar Roof Operation Lamp
ODN8H059312
When the solar roof is on, the lamp
installed in the upper part of the crash
pad illuminates.
Check Solar Roof Operation
ODN8HQ019006N
The solar roof operation status presents
three levels of the solar cell output. If
the solar roof information is selected
in the infotainment system, the battery
charging amount of the solar cell can be
checked
