WARNING
• Forward/Reverse Parking Distance
Warning is a supplemental function.
The operation of Forward/Reverse
Parking Distance Warning 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 while 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.

WARNING
Take the following precautions when
using Reverse Parking Collision-
Avoidance Assist: • Always pay extreme caution while
driving. The driver is responsible for
controlling the brake for safe driving.
• Always pay attention to road and
traffic conditions while driving,
whether or not there is a warning.
• Always look around your vehicle to
make sure there are no pedestrians
or objects before moving the vehicle.
• The performance of Reverse Parking
Collision-Avoidance Assist may
vary under certain conditions. If
vehicle speed is above 2 mph (4
km/h), Reverse Parking Collision-
Avoidance Assist will provide
collision avoidance assist only when
pedestrians are detected. Always
look around and pay attention when
backing up your vehicle.
• 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.
• Reverse Parking Collision-Avoidance
Assist may not operate properly
or may operate unnecessarily
depending on the road conditions
and the surroundings.
• Do not solely rely on Reverse Parking
Collision-Avoidance Assist. Doing
so may lead to vehicle damage or injuries. CAUTION
• Noise may be heard when sudden
braking occurs to avoid a collision.
• If any other warning sound such
as the seat belt warning chime is
already generated, Reverse Parking
Collision-Avoidance Assist warning
may not sound.
• Reverse Parking Collision-Avoidance
Assist may not work properly if the
bumper has been damaged, replaced
or repaired.
• Reverse Parking Collision-Avoidance
Assist may not operate properly if
interfered by strong electromagnetic
waves.
• Playing the vehicle audio system at
high volume may prevent passengers
from hearing Reverse Parking
Collision-Avoidance Assist warning sounds.
• Turn off Reverse Parking Collision-
Avoidance Assist when towing a
trailer. If towing and moving in
reverse, Reverse Parking Collision-
Avoidance Assist will activate as it
detects the trailer.
• The brake control may not operate
properly depending on the status of

only in a parking space that is large
enough for the vehicle to move
safely.
NOTICE
• If the 3rd stage warning (continuous
beep) of the Forward/Reverse
Parking Distance Warning sounds
while Remote Smart Parking
Assist is operating, it means the
obstacle detected is close to your
vehicle. At this time, Remote Smart
Parking Assist will temporarily stop
operating. Make sure there are no
pedestrians, animals, or objects
around your vehicle.
• Depending on brake operation, the
stop lights may come on while the

Tire Pressure Monitoring System
WARNING
Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire failure
that may cause loss of vehicle control
resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on
a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating
properly. The TPMS malfunction
indicator is combined with the low
tire pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly.
Always check the TPMS malfunction
telltale after replacing one or more tires
or wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
NOTICE
If any of the below happens, have
the system checked by an authorized
HYUNDAI dealer.
1. The Low Tire Pressure Telltale/ TPMS Malfunction Indicator does not
illuminate for 3 seconds when the
Start/Stop button is pressed to the
ON position or when the vehicle is running.
2. The TPMS Malfunction Indicator remains illuminated after blinking for
approximately 1 minute.
3. The Low Tire Pressure Position Telltale remains illuminated.

Low Tire Pressure
Warning Light
Low Tire Pressure Position and
Tire Pressure Telltale
ONE1081021L
When the tire pressure monitoring
system warning indicators are
illuminated and a warning message
displayed on the cluster LCD display,
one or more of your tires is significantly
under-inflated. The Low Tire Pressure
Position Telltale will indicate which
tire is significantly underinflated by
illuminating the corresponding position
light.
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 25 km/h (15.5 mph)) until
you have the low pressure tire repaired
and replaced on the vehicle.
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.

08
8-11
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. 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 1.6 km (1 mile) 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.
WARNING
This device complies with Part 15 of the
FCC rules.
Operation is subject to the following
three conditions: 1. This device may not cause harmful
interference.
2. This device must accept any
interference received, including
interference that may cause
undesired operation of the device.
3. Changes or modifications not
expressly approved by the party
responsible for compliance could
void the user’s authority to operate
the device.

For safe operation, carefully read and
follow the instructions in this manual
before use.
(1) Compressor
(2) Sealant bottle
The tire mobility kit is a temporary fix
to the tire, have the tire inspected by
an authorized HYUNDAI dealer or the
equivalent approved for your vehicle as soon as possible.
CAUTION
When two or more tires are flat, do not
use the tire mobility kit because the
supported one sealant of Tire Mobility
Kit is only used for one flat tire.
WARNING
Do not use the Tire Mobility Kit to repair
punctures in the tire walls. This can
result in an accident due to tire failure.
WARNING
Have your tire repaired as soon as
possible. The tire may lose air pressure
at any time after inflating with the Tire
Mobility Kit.
Introduction
With the Tire Mobility Kit you stay mobile
even after experiencing a tire puncture.
The compressor and sealing compound
system effectively and comfortably seals
most punctures in a passenger car tire
caused by nails or similar objects and
reinflates the tire.
After you ensure that the tire is properly
sealed you can drive cautiously on the
tire (distance up to 120 miles (200 km))
at a max. speed of ( 50 mph (80 km/h))
in order to reach a service station or tire
dealer for the tire replacement.
It is possible that some tires, especially
with larger punctures or damage to the
sidewall, cannot be sealed completely.
Air pressure loss in the tire may adversely
affect tire performance.
For this reason, you should avoid abrupt
steering or other driving maneuvers,
especially if the vehicle is heavily loaded
or if a trailer is in use.
The Tire Mobility Kit is not designed
or intended as a permanent tire repair
method and is to be used for one tire
only.
This instruction shows you step by step
how to temporarily seal the puncture
simply and reliably.
Read the section “Notes on the safe use
of the Tire Mobility Kit”.
WARNING
Do not use the TMK if a tire is severely
damaged by driving run flat or with
insufficient air pressure.
Only punctured areas located within the
tread region of the tire can be sealed using the TMK.
if you haVe a flat tire (with tire mobility Kit,
if equipped)
