System malfunction and
precautions
System malfunction
After starting the engine, a beep will
sound when the gear is shifted to R
(Reverse) to indicate the system 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
system be inspected by an authorized
HYUNDAI dealer.
• The audible warning does not sound.
• The buzzer sounds intermittently.
• The ‘Sensor error or blockage. System
limited’ warning message appears on
the cluster.

WARNING
• Reverse Parking Distance Warning
is a supplemental system. The
operation of the system can be
affected by several factors (including
environmental conditions). It is the
responsibility of the driver to always
check the rear view before and while
parking.
• Your new vehicle warranty does not
cover any accidents or damage to
the vehicle due to the malfunction of
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.
Limitations of the system
• Reverse Parking Distance Warning
may not operate normally when:
- Moisture is frozen to the sensor
- Sensor is covered with foreign
material, such as snow or water (The
system will operate normally when
such foreign material are removed.)
- The weather is extremely hot or cold
- The sensor or sensor assembly is
disassembled
- The surface of the sensor is pressed
hard or an impact is applied with a
hard object
- The surface of the sensor is
scratched with a sharp object
- The sensors or its surrounding area is
directly sprayed with high pressure
washer

• Reverse Parking Distance Warning
may malfunction when:
- Heavy rain or water spray is present
- Water flows on the surface of the
sensor
- Affected by another vehicle’s sensors
- The sensor is covered with snow
- Driving on uneven road, gravel roads
or bushes
- Objects that generates ultrasonic
waves are near the sensor
- Installing the license plate differently
from the original location
- The vehicle bumper height or
ultrasonic sensor installation has
been modified
- Attaching equipments or accessories
around the ultrasonic sensors
• The following objects may not be
detected:
- Sharp or slim objects, such as ropes,
chains or small poles.
- Objects, which tend to absorb sensor
frequency, such as clothes, spongy
material or snow.
- Objects smaller than 100 cm (40 in.)
in length and narrower than 14 cm (6
in.) in diameter.
- Pedestrians, animals or objects
that are very close to the ultrasonic
sensors
• Parking Distance Warning Indicators
may be displayed differently from
the actual detected location when
the obstacle is located between the
sensors.

may not occur sequentially depending
on vehicle speed or obstacle shape.
• If Reverse Parking Distance Warning
needs repair, we recommend that the
system be inspected by an authorized
HYUNDAI dealer.

NOTICE
If you park your vehicle near a stainless
steel sign or glass facade building, the
vehicle’s exterior plastic parts such
as a bumper, spoiler, garnish, lamp
or outside rearview mirror might be
damaged due to sunlight reflected
from the sign or building. To prevent
damage of the exterior plastic parts,
you should avoid parking in areas
where light may be reflected or use a
car cover. (The exterior plastic parts
applied to your vehicle may vary.)
Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
High-pressure washing
• When using high-pressure washers,
make sure to maintain sufficient
distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
• Do not spray the camera, sensors or
its surrounding area directly with a
high pressure washer. Shock applied
from high pressure water may cause
the device to not operate normally.
• Do not bring the nozzle tip close to
boots (rubber or plastic covers) or
connectors as they may be damaged
if they come into contact with high
pressure water.
Finish maintenance
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least once
a month with lukewarm or cold water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges
of the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.
After washing, rinse the vehicle
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
NOTICE
• Do not use strong soap, chemical
detergents or hot water, and do not
wash the vehicle in direct sunlight
or when the body of the vehicle is
warm.
• Be careful when washing the side
windows of your vehicle.
Especially, with high-pressure water,
water may leak through the windows
and wet the interior.
• To prevent damage to the plastic
parts and lamps, do not clean
with chemical solvents or strong
detergents.
