Tire sidewall labeling
This information identifies and
describes the fundamental
characteristics of the tire and also
provides the tire identification
number (TIN) for safety standard
certification. The TIN can be used to
identify the tire in case of a recall.
OHI078081
1. Manufacturer or brand name
Manufacturer or brand name is
shown
.
2. Tire size designation
A tire’s sidewall is marked with a
tire size designation. You will need
this information when selecting
replacement tires for your car.
The following explains what the
letters and numbers in the tire size
designation mean. Example tire size designation:
(These numbers are provided as
an example only; your tire size
designator could vary depending on
your vehicle.)
235/65 R17 95 H
235 -
Tire width in millimeters.
65 - Aspect ratio. The tire’s section
height as a percentage of its
width.
R - Tire construction code (Radial).

95 - Load Index, a numerical code
associated with the maximum
load the tire can carry.
H - Speed Rating Symbol. See the
speed rating chart in this section
for additional information.
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:

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 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 1520 represents that
the tire was produced in the 15th
week of 2020.
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.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A

Maintenance
9-38
Tread wear
The tread wear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test course.
For example, a tire graded 150 would
wear one-and-a-half times (1½) as
well on the government course as a
tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
sidewalls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest
to lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specified government test surfaces
of asphalt and concrete. A tire
marked C may have poor traction
performance.
WARNING
The traction grade assigned to
this tire is based on straightahead
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. Grades
B and A represent higher levels of
performance on the laboratory test
wheel than the minimum required
by law.
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.

09
9-39
Low aspect ratio tires
The aspect ratio is lower than 50 on
low aspect ratio tires.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than
a standard tire. Also low aspect
ratio tires tend to be wider and
consequently have a greater contact
patch with the road surface. In some
instances they may generate more
road noise compared with standard
tires
.
CAUTION
The side wall of a low aspect ratio
tire is shorter than the normal one.
Thus, the low-aspect wheel and
tire are easily damaged. Follow the
below instructions.
• When driving on a rough road or
driving off a road, be careful not
to damage the tires and wheels.
After driving, inspect the tires
and wheels.
• When passing over a pothole,
speed bump, manhole, or curb
stone, drive the vehicle slowly so
as not to damage the tires and
wheels.
• When there is an impact on a tire,
inspect the tire condition. Or,
you can contact an authorized
HYUNDAI dealer.
• Inspect the tire condition and
pressure every 1,800 miles (3,000
km) to prevent tire damage.
• It is difficult to recognize a tire
damage only with your eyes.
When there is a slight hint of a
tire damage, check and replace
the tire to prevent the damage
caused by air leakage.
• When a tire is damaged while
driving on a rough road, off a
road, or over obstacles, such as a
pothole, manhole, or curb stone,
your warranty does not cover the
damage.
• The tire information is specified
on the tire side wall.

A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 (or 3) fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment.
If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, turn the
engine and all switches off, and then
disconnect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this
indicates an electrical problem.
Avoid using the system involved. We
recommend that you immediately
consult an authorized HYUNDAI dealer.
Information
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge
type, and multi fuse for higher amperage
ratings.

WARNING
NEVER replace a fuse with anything but
another fuse of the same rating.
• A higher capacity fuse could cause
damage and possibly cause a fire.
• Do not install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.

7. Push in a new fuse of the same rating,
and make sure it fits tightly in the
clips. If it fits loosely, we recommend
that you consult an authorized
HYUNDAI dealer.
In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not need
for operating the vehicle, such as the
cigarette lighter fuse.
If the headlamps or other electrical
components do not work and the fuses
are undamaged, check the fuse panel
in the engine compartment. If a fuse is
blown, it must be replaced with the same
rating.
