Convenient Features5-42
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.

Operating conditions
Reverse Parking Collision-Avoidance
Assist system enters the ready status,
when ‘Active Assist’ or ‘Warning Only’ is
selected in the AVN system screen and
the following conditions are satisfied:
• The trunk is closed
• The shift lever is in R (Reverse)
• Vehicle speed is below 6 mph (10
km/h)
• System components such as the rear
view camera and the rear ultrasonic
sensors are in normal conditions
The driver needs to select ‘Active Assist’
on the LCD display or infotainment
system display for collision-avoidance
assist.
The solid lines behind the vehicle in the
cluster LCD display indicates that the
system is ready to assist the driver.
Note that the system assists the driver
only once. The driver has to shift the gear
to R (Reverse) from another gear position
to reactivate the system.
The performance of Reverse Parking
Collision-Avoidance Assist system may
vary under certain conditions. If the
vehicle speed exceeds 2 mph (3 km/h),
the system can assist only pedestrian
collision avoidance.
As always, be careful when backing
up your vehicle and be aware of your
surroundings.
Warning and System Control
Active assist
„„Cluster LCD display
ODN8A049043
„„Infotainment system display
OHI059255N
• If the system detects a risk of collision
with a pedestrian or an object behind
the vehicle, the system will warn the
driver with audible warning, steering
wheel vibration, and warnings on
the cluster LCD display and the
infotainment system display.
• If the system detects imminent
collision with a pedestrian or an object
behind the vehicle, the system may
apply braking power. The driver needs
to pay attention as the brake will
release within 2 seconds. The driver
must immediately depress the brake
pedal and check surroundings.

Key Ignition Switch (if equipped)
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions:
• NEVER allow children or any person
who is unfamiliar with the vehicle to
touch the ignition switch or related
parts. Unexpected and sudden
vehicle movement can occur.
• NEVER reach through the steering
wheel for the ignition switch, or any
other control, while the vehicle is in
motion. The presence of your hand
or arm in this area may cause a loss
of vehicle control resulting in an
accident.
OAE056172L
Whenever the front door is opened, the
ignition switch will illuminate, provided
the ignition switch is not in the ON
position. The light will go off immediately
when the ignition switch is turned on or
go off after about 30 seconds when the
door is closed. (if equipped)
WARNING
NEVER turn the ignition switch to the
LOCK or ACC position while the vehicle
is in motion except in an emergency.
This will result in the engine turning
off and loss of power assist for the
steering and brake systems. This may
lead to loss of directional control and
braking function, which could cause an
accident.
Before leaving the driver's seat, always
make sure the shift button is in P (Park)
position, apply the parking brake,
and turn ignition switch to the LOCK
position.
Unexpected vehicle movement may
occur if these precautions are not

WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:
• ALWAYS wear your seatbelt. In a
collision, an unbelted occupant
is significantly more likely to be
seriously injured or killed than a
properly belted occupant.
• Avoid high speeds when cornering or
turning.
• Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.
• The risk of rollover is greatly
increased if you lose control of your
vehicle at highway speeds.
• Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.
• In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
• HYUNDAI recommends you follow all
posted speed limits.
Information
Kickdown Mechanism (if equipped)
If you depress the accelerator pedal
equipped with Kickdown device beyond
the pressure point, it maximizes the engine
power. You may feel when the Kickdown
equipment starts to work and hear the
sound of Kickdown operation. It is normal
operation, not a failure.
