object in its sensing range. Also an
audible warning will sound.
• When more than two objects are
detected at the same time, the closest
one will be warned with an audible
warning.
• The shape of the indicator in the
illustration may differ from the actual
vehicle.
Function malfunction and
precautions
Function 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 whether the
system is in a non operating condition.
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.

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.
• 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:
- Mois

ture is frozen to the sensor
- Sensor is cov

ered with foreign
material, such as snow or water
(The system will operate normally
when such foreign material are
removed.)
- The w

eather is extremely hot or cold
- The sensor or sensor assembly is disassembled
- The surface o

f the sensor is pressed
hard or an impact is applied with a
hard object
- The surface o

f the sensor is
scratched with a sharp object
- The sensors or its surr

ounding
area is directly sprayed with high
pressure washer •
Reverse Parking Distance Warning
may malfunction when:
- Hea

sensor
- Aff

roads or bushes
- Objects that gener
ates ultrasonic
waves are near the sensor
- Installing the license pla
te
differently from the original location
- The vehicle bumper heigh
t or
ultrasonic sensor installation has
been modified
• The following objects may not be
detected:
-Sharp or slim objects, such as ropes,
chains or small poles.
- Objects, which tend t
o absorb
sensor frequency, such as clothes,
spongy material or snow.
- Objects smaller than 40 in. (100 cm) in length and narr

ower than 6 in. (14
cm) in diameter.
• Parking Distance Warning Indicators
may be displayed differently from
the actual detected location when
the obstacle is located between the
sensors.
• Parking Distance Warning indicator
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.

Driver assistance system

Reverse Parking Collision-Avoidance
Assist can warn the driver or can
assist with braking to help reduce the
possibility of collision with a pedestrian
or an object when backing up.
WARNING
• ALWAYS look around your vehicle to
make sure there are no pedestrians
or objects before moving the vehicle.
• Do not solely rely on the system.
Doing so may lead to vehicle damage
or injuries.
• Some objects may not be detected
by the rear ultrasonic sensors due
to the objects distance, size or
material, all of which can limit the
effectiveness of the sensor.

CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensors:
• Always keep the rear view camera
and rear ultrasonic sensors clean.
• Do not use any cleanser containing
acid or alkaline detergents when
cleaning the rear view camera lens.
Use only a mild soap or neutral
detergent, and rinse thoroughly with
water.
• Never disassemble or apply impact
on the rear view camera or the rear
ultrasonic sensors components.
• Do not apply unnecessary force on
the rear view camera or the rear
ultrasonic sensors. The system may
not operate properly if the rear
view camera or the rear ultrasonic
sensor(s) is forcibly moved out of
proper alignment. We recommend
that the vehicle be inspected by an
authorized HYUNDAI dealer.
• Do not spray the rear view camera or
the rear ultrasonic sensors or their
surrounding area directly with a
high pressure washer. It may cause
the rear view camera or the rear
ultrasonic sensors to malfunction.
• The function may not work properly
if the bumper has been damaged,
replaced or repaired.
• Do not apply objects, such as a
bumper sticker or a bumper guard,
near the rear view camera or rear
ultrasonic sensors or apply paint to
the bumper. Doing so may adversely
affect the performance of the
function.
• Reverse Parking Collision-Avoidance
Assist may not operate normally if
interfered by strong electromagnetic
waves.

no pedestrians or objects under the
following circumstances:
• Any non-factory equipment or
accessory is installed
• Your vehicle is unstable due to an
accident or other causes
• Bumper height or rear ultrasonic
sensor installation has been modified

If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tires as soon as possible. Inflate the
tires to the proper pressure as indicated
on the vehicle’s placard or tire inflation
pressure label located on the driver’s
side center pillar outer panel.
If you cannot reach a service station or
if the tire cannot hold the newly added
air, replace the low pressure tire with the
spare tire.
The Low Tire Pressure Telltale will remain
on and the TPMS Malfunction Indicator
may blink for one minute and then
remain illuminated (when the vehicle
is driven approximately 10 minutes at
speed above 15.5 mph (25km/h)) until
you have the low pressure tire repaired
and replaced on the vehicle.
Information
The spare tire is not equipped with a tire
pressure sensor.
CAUTION
In winter or cold weather, the Low Tire
Pressure Telltale may be illuminated if
the tire pressure was adjusted to the
recommended tire inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning because
the decreased temperature leads to a
proportional lowering of tire pressure.
When you drive your vehicle from a
warm area to a cold area or from a cold
area to a warm area, or the outside
temperature is greatly higher or lower,
you should check the tire inflation
pressure and adjust the tires to the
recommended tire inflation pressure.
WARNING
Low pressure damage
Significantly low tire pressure makes
the vehicle unstable and can contribute
to loss of vehicle control and increased
braking distances.
Continued driving on low pressure tires
can cause the tires to overheat and fail.
