Emergency Situations7-8
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 TPMS Malfunction Indicator does not
illuminate for 3 seconds when the
ignition switch is placed to the ON
position or engine is running.
2. The TPMS Malfunction Indicator remains illuminated after blinking for
approximately 1 minute.
3. The Low Tire Pressure LCD display remains illuminated

Low Tire Pressure Telltale
Low Tire Pressure LCD Display
with Position Indicator
ODN8049019LODN8049019L
When the tire pressure monitoring
system warning indicators are
illuminated and the warning message
is displayed on the cluster LCD
display, one or more of your tires is
significantly under-inflated. The LCD
position indicator will indicate which
tire is significantly under-inflated by
illuminating the corresponding position
light.
If any of your tire pressures are indicated
as being low, 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. (if equipped)
The Low Tire Pressure LCD position
indicator will remain on and the TPMS
Malfunction Indicator may blink for one
minute and then remain illuminated until
you have the low pressure tire repaired
and replaced on the vehicle.
NOTICE
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.

Emergency Situations7-10
TPMS 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.
Have the system checked by an
authorized HYUNDAI dealer as soon as
possible.
NOTICE
If there is a malfunction with the
TPMS, the individual tire pressures
in the cluster LCD display will not be
available. Have the system checked by
an authorized HYUNDAI dealer as soon
as possible.
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 LCD position indicator will
come on. Have the flat tire repaired by an
authorized HYUNDAI dealer as soon as
possible or replace the flat tire with the
spare tire. (if equipped)
CAUTION
It is recommended that you do not use a
puncture-repairing agent not approved
by HYUNDAI dealer to repair and/or
inflate a low pressure tire. Tire sealant
not approved by HYUNDAI dealer may
damage the tire pressure sensor.
The spare tire 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 LCD position indicator 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 (25 km/h) for
approximately 20 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 LCD position indicator and
TPMS Malfunction Indicator will go off
within a few minutes of driving.
If the indicators do not disappear after a
few minutes, please visit an authorized
HYUNDAI dealer.

3. Checking tire life (TIN : Tire Identification Number)
Any tires that are over six years old,
based on the manufacturing date,
(including the spare tire) should be
replaced by new tires. You can find the
manufacturing date on the tire sidewall
(possibly on the inside of the wheel),
displaying the DOT Code. The DOT Code
is a series of numbers on a tire consisting
of numbers and English letters. The
manufacturing date is designated by the
last four digits (characters) of the DOT
code.
DOT : XXXX XXXX OOOO
The front part of the DOT shows a plant
code number, tire size and tread pattern
and the last four numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 1419 represents that the
tire was produced in the 14th week of
2019.
4. Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include steel,
nylon, polyester, and others. The letter
“R” means radial ply construction; the
letter “D” means diagonal or bias ply
construction; and the letter “B” means
belted-bias ply construction.
5. Maximum permissible inflation pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer to
the Tire and Loading Information label
for recommended inflation pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can be
carried by the tire. When replacing the
tires on the vehicle, always use a tire that
has the same load rating as the factory
installed tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width.
