Maintenance
Owner Maintenance Schedule
When you stop for fuel:

[Check the coolant level in the engine
coolant reservoir or the liquid-cooled
intercooler coolant reservoir.

[Check the windshield washer fluid
level.

[Check for low or under-inflated tires.
WARNING
Be careful when checking your coolant
level if the motor compartment is hot.
This may result in coolant being blown
out of the opening and cause serious
burns and other injuries.
While operating your vehicle:

[Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.

[Check for vibrations in the steering
wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.

[Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling on smooth, level road.

[When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.

[If any slipping or changes in the
operation of your transmission occurs,
check the transmission fluid level.

[Check the automatic transmission P
(Park) function.

[Check the parking brake.

[Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:

[Check coolant level in the engine
coolant reservoir.

[Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.

[Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are
damaged.

[Check for loose wheel lug nuts.
At least twice a year: (for example,
every Spring and Autumn)

[Check radiator, heater and air
conditioning hoses for leaks or
damage.

[Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.

[Check headlight alignment.

[Check muffler, exhaust pipes, shields
and clamps.

[Check the seat belts for wear and
function.
At least once a year:

[Clean body and door drain holes.

[Lubricate door hinges and hood
hinges.

[Lubricate door and hood locks and
latches.

[Lubricate door rubber weather strips.

[Check the air conditioning system.

[Inspect and lubricate automatic
transmission linkage and controls.

[Clean the battery and terminals.

[Check the brake fluid level.

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

9-34
Maintenance
WARNING
Recommended pressures must be
maintained for the best ride, vehicle
handling, and minimum tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and lead to
sudden tire failure that could result
in loss of vehicle control resulting in
an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result in
the loss of vehicle control resulting
in an accident. This risk is much
higher on hot days and when
driving for long periods at high
speeds.
CAUTION

[Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tire pressures
at the proper levels. If a tire
frequently needs refilling, have it
checked by an authorized retailer
of Genesis Branded products.

[Over-inflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater
possibility of damage from road
hazards.
Check tire Inflation Pressure
Check your tires, including the spare
tire(if equipped), once a month or
more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You
can not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly
inflated when they are under-
inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge
firmly onto the valve to get a
pressure measurement. If the cold
tire inflation pressure matches the
recommended pressure on the tire
and loading information label, no
further adjustment is necessary. If
the pressure is low, add air until you
reach the recommended pressure.
Make sure to put the valve caps
back on the valve stems. Without
the valve cap, dirt or moisture could
get into the valve core and cause
air leakage. If a valve cap is missing,
install a new one as soon as possible.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.

Tire speed ratings
The chart below lists many of the
different speed ratings currently
being used for passenger vehicle
tires. The speed rating is part of the
tire size designation on the sidewall
of the tire. This symbol corresponds
to that tire’s designed maximum safe
operating speed.
Speed Rating
SymbolMaximum Speed
S 112 mph (180 km/h)
T 118 mph (190 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (300 km/h)
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.

WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded.
Excessive speed, under-inflation,
over-inflation, or excessive loading,
either separately or in combination,
can cause heat build-up and
possible sudden tire failure. This
may cause loss of vehicle control
resulting in an accident.
