Maintenance
8-20
Engine Oil and Filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule.
Drive Belts
Inspect all drive belts for evidence
of cuts, cracks, excessive wear or oil
saturation and replace if necessary. Drive
belts should be checked periodically
for proper tension and adjusted as
necessary.
Fuel Filter
A clogged-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the hard
starting. When a considerable amount
of foreign substances are accumulated
in the fuel tank, the fuel filter should be
replaced.
Upon installing a new fuel filter, operate
the engine for several minutes, and
check the connections for any leakages.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
Fuel Lines, Fuel Hoses and Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
Have an authorized HYUNDAI dealer
replace any damaged or leaking parts
immediately.
Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
a new vapor hose or fuel filler cap is
correctly replaced.
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs of
the correct heat range.
Cooling System
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.

Wheel size designation
Wheels are also marked with important
information that you need if you ever
have to replace one. The following
explains what the letters and numbers in
the wheel size designation mean.
Example wheel size designation:6.5J X 16
6.5 - Rim width in inches.
J - Rim contour designation.
16 - Rim diameter in inches.
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 Symbol Maximum Speed
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
W 270 km/h (168 mph) Y 300 km/h (186 mph) 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 1421 represents that the
tire was produced in the 14th week of 2021.
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.

WARNING
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
Temperature A, B & C
The temperature grades are A (the
highest), B and C representing the tire’s
resistance to the generation of heat
and its ability to dissipate heat when
tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure.
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.
Tire Terminology and Definitions
Air Pressure
The amount of air inside the tire pressing
outward on the tire. Air pressure is
expressed in kilopascal (kPa) or pounds
per square inch (psi).
Accessory Weight
This means the combined weight of
optional accessories. Some examples
of optional accessories are automatic
transmission, power seats, and air conditioning.
Aspect Ratio
The relationship of a tire’s height to its width. Belt
A rubber coated layer of cords that is
located between the plies and the tread.
Cords may be made from steel or other
reinforcing materials. Bead
The tire bead contains steel wires
wrapped by steel cords that hold the tire
onto the rim.
Bias Ply Tire
A pneumatic tire in which the plies are
laid at alternate angles less than 90
degrees to the centerline of the tread.
Cold Tire Pressure
The amount of air pressure in a tire,
measured in kilopascals (kPa) or pounds
per square inch (psi) before a tire has
built up heat from driving.
Curb Weight
This means the weight of a motor vehicle
with standard and optional equipment
including the maximum capacity of fuel,
oil and coolant, but without passengers
and cargo.

Maintenance

All Season Tires
HYUNDAI specifies all season tires
on some models to provide good
performance for use all year round,
including snowy and icy road conditions.
All season tires are identified by ALL
SEASON and/or M+S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than all season tires and
may be more appropriate in some areas.
Summer Tires
HYUNDAI specifies summer tires on
some models to provide superior
performance on dry roads. Summer tire
performance is substantially reduced in
snow and ice. Summer tires do not have
the tire traction rating M+S (Mud and
Snow) on the tire side wall. If you plan
to operate your vehicle in snowy or icy
conditions, HYUNDAI recommends the
use of snow tires or all season tires on all
four wheels.
Snow Tires
If you equip your car with snow tires,
they should be the same size and have the same load capacity as the original
tires. Snow tires should be installed on
all four wheels; otherwise, poor handling
may result. Snow tires should carry 28
kPa (4 psi) more air pressure than the
pressure recommended for the standard
tires on the tire label on the driver’s
side of the center pillar, or up to the
maximum pressure shown on the tire
sidewall, whichever is less. Do not drive
faster than 120 km/h (75 mph) when your
vehicle is equipped with snow tires.
Radial-Ply Tires
Radial-ply tires provide improved tread
life, road hazard resistance and smoother
high speed ride. The radial-ply tires used
on this vehicle are of belted construction,
and are selected to complement the
ride and handling characteristics of your
vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or bias
belted tires of the same size, and use the
same recommended inflation pressure.
Mixing of radial-ply tires with bias-ply or
bias belted tires is not recommended.
Any combinations of radial-ply and bias-
ply or bias belted tires when used on the
same vehicle will seriously deteriorate
vehicle handling. The best rule to follow
is: Identical pairs of radial-ply tires
should always be used as a set for the
front tires and a set for the rear tires.
Longer wearing tires can be more
susceptible to irregular tread wear. It is
very important to follow the tire rotation
interval in this chapter to achieve the
tread life potential of these tires. Cuts
and punctures in radial-ply tires are
repairable only in the tread area, because
of sidewall flexing. Consult your tire
dealer for radial-ply tire repairs.
WARNING
Do not mix bias ply and radial ply tires
under any circumstances. This may
cause unusual handling characteristics
that may cause loss of vehicle control
resulting in an accident.

NOTICE
Using anything but recommended
cleaners and procedures may affect the
fabric’s appearance and fire-resistant
properties.
Leather (if equipped)
• Features of seat leather
- Leather is made from the outer skin of an animal, which goes through a
special process to be available for
use. Since it is a natural product,
each part differs in thickness or
density.
Wrinkles may appear as a natural
result of stretching and shrinking
depending on the temperature and
humidity.
- The seat is made of stretchable fabric to improve comfort.
- The parts contacting the body are curved and the side supporting
area is high which provides driving
comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
products.
CAUTION
• Wrinkles or abrasions which appear
naturally from usage are not covered
by warranty.
• Belts with metallic accessories,
zippers or keys inside the back
pocket may damage the seat fabric.
• Make sure not to wet the seat. It may
change the nature of natural leather.
• Jeans or clothes which could bleach
may contaminate the surface of the
seat covering fabric. •
Caring for the leather seats
- Vacuum the seat periodically to remove dust and sand on the seat. It
will prevent abrasion or damage of
the leather and maintain its quality.
- Wipe the natural leather seat cover often with dry or soft cloth.
- Use of proper leather protector may prevent abrasion of the cover and
helps maintain the color. Be sure to
read the instructions and consult
a specialist when using leather
coating or protective agent.
- Light colored (beige, cream beige) leather is easily contaminated and
the stain is noticeable. Clean the
seats frequently.
- Avoid wiping with wet cloth. It may cause the surface to crack.
• Cleaning the leather seats
- Remove all contaminations instantly. Refer to instructions below
for removal of each contaminant.
- Cosmetic products (sunscreen, foundation, etc.)
Apply cleansing cream on a cloth
and wipe the contaminated spot.
Wipe off the cream with a wet cloth
and remove water with a dry cloth.
- Beverages (coffee, soft drink, etc.) Apply a small amount of neutral
detergent and wipe until
contaminations do not smear.
- Oil Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natural
leather.
- Chewing gum Harden the gum with ice and
remove gradually.

Cleaning the seat belt webbing
Clean the belt webbing with any
mild soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the soap.
Do not bleach or re-dye the webbing
because this may weaken the seat belt.
Cleaning the interior window glass
If the interior glass surfaces of the
vehicle become hazy (that is, covered
with an oily, greasy or waxy film), they
should be cleaned with glass cleaner.
Follow the directions on the glass cleaner
container.
NOTICE
Do not scrape or scratch the inside of
the rear window. This may result in
damage to the rear window defroster grid.
