Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger car 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 oper-
ating speed.
3. Checking tire life
(TIN : Tire Identification
Number)
Any tires that are over 6 years old,
based on the manufacturing date,
tire strength and performance,
decline with age naturally (even
unused spare tires). Therefore, the
tires (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 num-
bers and English letters. The manu-
facturing date is designated by the
last four digits (characters) of the
DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1614 represents
that the tire was produced in the 16th
week of 2014.
Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires generally be replaced after
six (6) years of normal service.
Heat caused by hot climates or
frequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
Warning can result in sudden
tire failure, which could lead to
a loss of control and an acci-
dent involving serious injury or
death.

4. Tire ply composition and
material
The number of layers or plies of rub-
ber-coated fabric are 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 con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible infla-
tion pressure
This number is the greatest amountof air pressure that should be put inthe tire. Do not exceed the maximumpermissible inflation pressure. Referto the Tire and Loading Informationlabel for recommended inflationpressure.
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 maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tr e a d w e a r
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment 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
because of variations in driving
habits, service practices and differ-
ences in road characteristics and cli-
mate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
may vary with respect to grade.

Maintenance
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tires ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
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 condi-
tions 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 perform-
ance on the laboratory test wheel
than the minimum required by the
law.
Tire temperature
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
build-up and possible sudden
tire failure. This can cause loss
of vehicle control and serious
injury or death.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.

Maintenance
Low aspect ratio tire
(if equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided
for spor ty looks.
Because the low aspect ratio tires
are optimized for handling and brak-
ing, it may be more uncomfortable to
ride in and there is more noise com-
pare with normal tires.
Because the sidewall of the low
aspect ratio tire is shorter than
the normal, the wheel and tire of
the low aspect ratio tire is easi-
er to be damaged. So, follow the
instructions below.
- When driving on a rough road
or off road, drive cautiously
because tires and wheels may
be damaged. And after driving,
inspect tires and wheels.
- When passing over a pothole,
speed bump, manhole, or curb
stone, drive slowly so that the
tires and wheels are not dam-
aged.
- If the tire is impacted, we rec-
ommend that you inspect the
tire condition or contact an
authorized HYUNDAI dealer.
- To prevent damage to the tire,
inspect the tire condition and
pressure every 3,000km.
CAUTION
•It is not easy to recognize the
tire damage with your own
eyes. But if there is the slight-
est hint of tire damage, even
though you cannot see the
tire damage with your own
eyes, have the tire checked or
replaced because the tire
damage may cause air leak-
age from the tire.
•If the tire is damaged by driv-
ing on a rough road, off road,
pothole, manhole, or curb
stone, it will not be covered by
the warranty.

FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted.
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 bat-
tery cable. Always replace a blown
fuse with one of the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid
using the system involved and immedi-
ately consult an authorized HYUNDAI
dealer.
Information
Three kinds of fuses are used:
blade type for lower amperage rat-
ing, cartridge type and multi fuse
for higher amperage ratings.

Fuse replacement
•Never replace a fuse with any-
thing but another fuse of the
same rating.
•A higher capacity fuse could
cause damage and possibly a
fire.
•Never install a wire or alu-
minum foil instead of the prop-
er fuse - even as a temporary
repair. It may cause extensive
wiring damage and a possible
fire.
WARNING
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.
CAUTION
•When replacing a blown fuse
or relay with a new one, make
sure the new fuse or relay fits
tightly into the clips. The
incomplete fastening fuse or
relay may cause the vehicle
wiring and electric systems
damage and a possible fire.
•Do not remove fuses, relays
and terminals fastened with
bolts or nuts. The fuses,
relays and terminals may be
fastened incompletely, and it
may cause a possible fire. If
fuses, relays and terminals
fastened with bolts or nuts are
blown, we recommend that
you consult an authorized
HYUNDAI dealer.
•Do not input any other objects
except fuses or relays into
fuse/relay terminals such as a
driver or wiring. It may cause
contact failure and system
malfunction.
