In the following cases, the vehicle
in front cannot be detected by the
sensor:
- Vehicles with higher ground
clearance or vehicles carrying loads
that stick out of the back of the
vehicle
- Vehicles that has the front lifted due
to heavy loads
- You are steering your vehicle
- Driving on narrow or sharply curved
roads
Adjust your vehicle speed by
depressing the brake pedal according
to the road and driving conditions
ahead.

[When a vehicle ahead disappears
at an intersection, your vehicle may
accelerate.
Always pay attention to road and
driving conditions whilst driving.
OJX1070294R

[When a vehicle in front of you merges
out of the lane, Smart Cruise Control
may not immediately detect the new
vehicle that is now in front of you.
Always pay attention to road and
driving conditions whilst driving.

and precautions
Forward/Reverse Parking Distance
Warning malfunction
After starting the engine, a beep will
sound when the gear is shifted to R
(Reverse) to indicate the function is
operating normally.
However, if one or more of the following
occurs, first check whether the
ultrasonic sensor is damaged or blocked
with foreign material. If it still does not
work properly, we recommend that the
function be inspected by a HYUNDAI
authorised repairer.

[The audible warning does not sound.

[The buzzer sounds intermittently.

WARNING

[Forward/Reverse Parking Distance
Warning is a supplemental system.
The operation of the function can be
affected by several factors (including
environmental conditions). It is the
responsibility of the driver to always
check the front and rear views before
and whilst parking.

[Your new vehicle warranty does not
cover any accidents or damage to
the vehicle due to the malfunction of
Forward/Reverse Parking Distance
Warning.

[Pay close attention when driving near
objects, pedestrians, and especially
children. Some objects may not be
detected by the ultrasonic sensors,
due to the objects distance, size or
material, all of which can limit the
effectiveness of the sensor.

[Parking Assist helps the driver with
perpendicular reverse parking and
parallel reverse parking, and when
leaving the parking space, parallel
forward exit is assisted.

[When Parking Assist operates, Parking
Distance Warning will also operate.

3. Checking space
(1) When the vehicle is parked parallel,
the vehicle sensors will detect the
distance from nearby objects and
check for space to exit.

[If the front or rear vehicle (or object) is
too near, the function will not be able
to search for space, and will turn off.

[Parking Assist may not be able to
search for space even if there is space
to leave, and the function may search
for a space that is not suitable for
the vehicle to leave in the following
circumstances:
- The ultrasonic sensor is frozen or
dirty
- There are objects located high or low
- There are pillars around the parking
space
- The parked vehicle has objects
attached to the bumper such as
bumper guard, trailer hitch, etc. OBC3070100TU/OBC3070102TU

4. Steering wheel control
(1) Shift the gear to D (Drive) or R
(Reverse) according to the message
on the cluster.
(2) Parking Assist will start to control the
steering wheel.
- If the steering wheel is held tight,
Parking Assist will be cancelled.
(3) Take your foot off the brake pedal
and drive forward or in reverse
according to the message on the
