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,
(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 num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing 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 1611 represents
that the tire was produced in the 16th
week of 2011.
S 112 mph (180 km/h)
T 118 mph (190 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
Z Above 149 mph (240 km/h)

WARNING - 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 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 inflation
pressure
This number is the greatest amount of
air pressure that should be put in the
tire. Do not exceed the maximum per-
missible 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 maxi-
mum section width.
For example: TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wear
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
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
side-walls 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 spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
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.

46 7
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. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.Tire terminology and definitions
Air Pressure: The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
pounds per square inch (psi) or kilo-
pascal (kPa).
Accessory Weight: This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic
transaxle, power seats, and air con-
ditioning.
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.WARNING - 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.

Maintenance
Do not drive faster than 75 mph (120
km/h) when your car is equipped with
snow tires.
Tire chains
Tire chains, if necessary, should be
installed on the front wheels.
Be sure that the chains are installed
in accordance with the manufactur-
er's instructions.
To minimize tire and chain wear, do
not continue to use tire chains when
they are no longer needed.
✽ ✽
NOTICE
Use the TMK in a range of noticed war-
ranty period.
Before you use the TMK, read the
owner's manual for your safety.
Radial-ply tires
Radial-ply tires provide improved
tread life, road hazard resistance and
smoother high speed ride. The radi-
al-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 combina-
tions 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 fol-
low is: Identical radial-ply tires should
always be used as a set of four.
Longer wearing tires can be more
susceptible to irregular tread wear. It
is very important to follow the tire
rotation interval shown in this section
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- Snow or ice
When driving on roads cov-
ered with snow or ice, drive at
less than 20 mph (30 km/h).
Use the SAE “S” class or wire
chains.
If you hear noise caused by
chains contacting the body,
retighten the chain to avoid
contact with the vehicle body.
To prevent body damage,
retighten the chains after driv-
ing 0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on
vehicles equipped with alu-
minum wheels. In unavoid-
able circumstance, use a wire
type chain.
Use wire chains less than 0.47
inches (12 mm) to prevent
damage to the chain’s con-
nection.

FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.This vehicle has 2 fuse panels, one locat-
ed in the driver’s side panel bolster, the
other in the engine compartment.
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.
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 immediately
consult an authorized HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,
and multi fuse for higher amperage rat-
ings.

WARNING - Fuse replace-
ment
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 instead of the
proper fuse - even as a temporary
repair. It may cause extensive
wiring damage and a possible fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove fuses
because it may cause a short circuit
and damage the system.

LIGHT BULBS
Use only bulbs of the specified wattage.
✽
✽
NOTICE
After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorized HYUNDAI dealer.WARNING - Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the engine start/stop button is
turned to the LOCK position and
turn off the lights to avoid sudden
movement of the vehicle and burn-
ing your fingers or receiving an
electric shock.
CAUTION
Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause
damage to the fuse or electric
wiring system.
CAUTION
If you don’t have necessary tools,
the correct bulbs and the expertise,
consult an authorized HYUNDAI
dealer. In many cases, it is difficult
to replace vehicle light bulbs
because other parts of the vehicle
must be removed before you can
get to the bulb. This is especially
true if you have to remove the head-
light assembly to
get to the bulb(s).
Removing/installingthe headlight
assembly can result in damage to
the vehicle.
WARNING
When you replace the bulb of front-
light, be careful the HPCU system,
high voltage cable (orange color)
and high voltage components for
hybrid.
It is very dangerous because the
HPCU has the high voltage. Always
pay strongly attention to your
hands. If not, it may result in the
electric shock or burns.
