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:
-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
• 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 40 in. (100 cm)
in length and narrower 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
7-116
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.

Emergency Situations
8-12
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.

TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS Malfunction Indicator
will illuminate after it blinks for
approximately one minute when there
is a problem with the Tire Pressure
Monitoring System.
We recommend that the system be
checked by an authorized HYUNDAI
dealer.
NOTICE
If there is a malfunction with the TPMS,
the Low Tire Pressure Position Telltale
will not be displayed even though the
vehicle has an under-inflated tire.
NOTICE
The TPMS Malfunction Indicator may
illuminate after blinking for one minute
if the vehicle is near electric power
supply cables or radio transmitters
such as police stations, government
and public offices, broadcasting
stations, military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow chains
are used or electronic devices such as
computers, chargers, remote starters,
navigation, etc. This may interfere with
normal operation of the TPMS.
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure and Position telltales will come
on. We recommend that the flat tire be
repaired by an authorized HYUNDAI
dealer as soon as possible or replace the
flat tire with the spare tire.
NOTICE
It is recommended that you do not use a
puncture-repairing agent not approved
by a HYUNDAI dealer to repair and/or
inflate a low pressure tire. Tire sealant
not approved by a HYUNDAI dealer may
damage the tire pressure sensor.
The spare tire (if equipped) does not
come with a tire pressure monitoring
sensor. When the low pressure tire or
the flat tire is replaced with the spare
tire, the Low Tire Pressure Telltale will
remain on. Also, the TPMS Malfunction
Indicator will illuminate after blinking
for one minute if the vehicle is driven
at speed above 15.5 mph (25km/h) for
approximately 10 minutes.
Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pressure
and reinstalled on the vehicle, the
Low Tire Pressure Telltale and TPMS
Malfunction Indicator will go off within a
few minutes of driving.
If the indicators do not extinguish after a
few minutes, please visit an authorized
HYUNDAI dealer.

Emergency Situations
8-14
Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem (except for the
spare tire). You must use TPMS specific
wheels. It is recommended that you
always have your tires serviced by an
authorized HYUNDAI dealer.
You may not be able to identify a tire
with low pressure by simply looking at it.
Always use a good quality tire pressure
gauge to measure the tire’s inflation
pressure. Please note that a tire that is
hot (from being driven) will have a higher
pressure measurement than a tire that is
cold.
A cold tire means the vehicle has been
sitting for 3 hours and driven for less
than 1 mile (1.6 km) in that 3 hour period.
Allow the tire to cool before measuring
the inflation pressure. Always be sure
the tire is cold before inflating to the
recommended pressure.
WARNING
• The TPMS cannot alert you to severe
and sudden tire damage caused by
external factors such as nails or road
debris.
• If you feel any vehicle instability,
immediately take your foot off
the accelerator, apply the brakes
gradually with light force, and slowly
move to a safe position off the road.
WARNING
Tampering with, modifying, or disabling
the Tire Pressure Monitoring System
(TPMS) components may interfere
with the system’s ability to warn the
driver of low tire pressure conditions
and/or TPMS malfunctions. Tampering
with, modifying, or disabling the Tire
Pressure Monitoring System (TPMS)
components may void the warranty for
that portion of the vehicle.
