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 ATread 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.

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 tempera-
ture 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 law.Low aspect ratio tire
(if equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided
for sporty 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.
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 sudden tire failure.
This can cause loss of vehicle
control and serious injury or
death.
CAUTION
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.
(Continued)
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.
• You can find out the tire infor-
mation on the tire sidewall.
(Continued)
- 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.

FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.This vehicle has 4 fuse panels, one
located in the driver’s side panel bol-
ster, another is in the front passen-
ger’s side panel bolster, the others
are 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.
Before replacing a blown fuse, dis-
connect 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 and we
recommend that you consult an
authorized HYUNDAI dealer.Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link for higher
amperage ratings.
✽NOTICE
The actual fuse/relay panel label
may differ from equipped items.
WARNING - 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
proper fuse - even as a tem-
porary 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.

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 fas-
tened incompletely, and it may
cause a possible fire. If fuses,
relays and terminals fastened
with bolts or nuts are blown,
we recommend that you con-
sult with 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.

4.Check the removed fuse; replace it
if it is blown.
Spare fuses are provided in the
passenger compartment panel
fuse panel (or in the engine com-
partment fuse panel).
5.Push in a new fuse of the same rat-
ing, and make sure it fits tightly in
the clips.
If it fits loosely, we recommend that
you consult an authorized HYUNDAI
dealer.
If you do not have a spare, 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 headlights or other electrical
components do not work and the
fuses are OK, check the fuse panel
in the engine compartment. If a fuse
is blown, it must be replaced.
Fuse switch
Always, put the fuse switch at the ON
position.
If you move the switch to the OFF
position, some items such as audio
and digital clock must be reset and
the smart key may not work properly.
OVI073102
CAUTION
• Always place the fuse switch
in the ON position while driv-
ing the vehicle.
• Do not move the transporta-
tion fuse switch repeatedly.
The fuse switch may be worn
out.

mend that you consult an authorized
HYUNDAI dealer.
CAUTION
After checking the fuse panel in
the engine compartment,
securely install the fuse panel
cover. If not, electrical failures
may occur from water contact.OBH078025OBH071023
