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
retailer of Genesis Branded products.
1. The Low Tire Pressure Telltale/ TPMS
Malfunction Indicator does not
illuminate for 3 seconds when the
Engine Start/Stop button is pressed
to the ON position or when the
engine is running.
2. The TPMS Malfunction Indicator
remains illuminated after blinking for
approximately 1 minute.
3. The Low Tire Pressure Position
Telltale remains illuminated.

Emergency Situations
When driving with the compact spare tire
mounted to your vehicle:
• Check the tire pressure after installing
the compact spare tire. The compact
spare tire should be inflated to 60 psi
(420 kPa).
• Do not take this vehicle through
an automatic car wash while the
compact spare tire is installed.
• Do not use the compact spare tire on
any other vehicle because this tire
has been designed especially for your
vehicle.
• The compact spare tire’s tread life is
shorter than a regular tire. Inspect
your compact spare tire regularly and
replace worn compact spare tires with
the same size and design, mounted on
the same wheel.
• Do not use more than one compact
spare tire at a time.
• Do not tow a trailer while the compact
spare tire is installed.
Information
When the original tire and wheel are
repaired and reinstalled on the vehicle, the
wheel bolt torque must be set correctly.
The correct wheel bolt tightening torque is
101~116 lbf·ft (14~16 kgf·m).
NOTICE
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards, such
as a potholes or debris.
• Avoid driving over obstacles. The
compact spare tire diameter is
smaller than the diameter of a
conventional tire and reduces the
ground clearance approximately
1 in. (25 mm).
• Do not use tire chains on the
compact spare tire. Because of the
smaller size, a tire chain will not fit
properly.
• Do not use the compact spare tire
on any other wheels, nor should
standard tires, snow tires, wheel
covers or trim rings be used with the
compact spare wheel.
• Do not suddenly accelerate or
decelerate 0 ~ 25 mph (0 ~ 40 km/h)
in any driving mode. It may cause
leakage of transfer oil.

WARNING
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of SERIOUS
INJURY or DEATH, take the
following precautions:

[Inspect your tires monthly for
proper inflation as well as wear
and damage.

[The recommended cold tire
pressure for your vehicle can be
found in this manual and on the
tire label located on the driver’s
side center pillar. Always use a
tire pressure gauge to measure
tire pressure. Tires with too
much or too little pressure wear
unevenly causing poor handling.

[Check the pressure of the
spare every time you check the
pressure of the other tires on
your vehicle.

[Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, or traction.

[ALWAYS replace tires with the
same size, type, construction and
tread pattern as each tire that
was originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.
Tire Care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended
tire inflation pressures and stay
within the load limits and weight
distribution recommended for your
vehicle.
ORS012024N
All specifications (sizes and
pressures) can be found on a label
attached to the driver’s side center
pillar.
Recommended Cold Tire
Inflation Pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold tires” means the
vehicle has not been driven for at
least three hours or driven less than
one mile (1.6 km).
Warm tires normally exceed
recommended cold tire pressures
by 4 to 6 psi (28 to 41 kPa). Do not
release air from warm tires to adjust
the pressure or the tires will be
under-inflated. For recommended
inflation pressure, refer to “Tire and
Wheels” section in chapter 2.
TIRES AND WHEELS

9-36
Maintenance
Wheel Alignment and Tire
Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
NOTICE
Incorrect wheel weights can
damage your vehicle’s aluminum
wheels. Use only approved wheel
weights.
Tire Replacement
ORS091057
A : Tread wear indicator
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before
replacing the tire.
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:

[Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, and traction.

[Always replace tires with the
same size as each tire that was
originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.

[When replacing tires (or wheels),
it is recommended to replace
the two front or two rear tires (or
wheels) as a pair. Replacing just
one tire can seriously affect your
vehicle’s handling.

[Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, Genesis Branded Vehicle
recommends that tires be
replaced after six (6) years of
normal service.

[Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging process.
Failure to follow this warning
may cause sudden tire failure,
which could lead to a loss of
vehicle control resulting in an
accident.

Compact spare tire (if equipped)
replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is
not designed to be mounted on a
regular size wheel, and the compact
spare tire wheel is not designed for
mounting a regular size tire.
WARNING
The original tire should be repaired
or replaced as soon as possible to
avoid failure of the compact spare
tire and loss of vehicle control
resulting in an accident. The
compact spare tire is for emergency
use only. Do not operate your
vehicle over 50 mph (80 km/h)
when using the compact spare tire.
Wheel Replacement
When replacing the metal wheels
for any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tire Traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tire Maintenance
In addition to proper inflation,
correct wheel alignment helps to
decrease tire wear. If you find a tire
is worn unevenly, have your dealer
check the wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort
and tire life. Additionally, a tire
should always be rebalanced if it is
removed from the wheel.

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 ones. 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 1522 represents that
the tire was produced in the 15th
week of 2022.4. Genesis exclusive tire
Genesis Branded Vehicle
recommends that tires designed
specifically for Genesis vehicles
be used. You may find the marking
“GOE” (Genesis Original Equipment)
embossed on the tire sidewall.
5. 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.
6. 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.
7. 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.
