Maintenance
NOTICE
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 easier 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 damaged.
- If the tire is impacted, we
recommend 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.
NOTICE
• It is not easy to recognize the tire
damage with your own eyes. But
if there is the slightest 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 leakage from the tire.
• If the tire is damaged by driving
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 information
on the tire sidewall.

A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 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 and
we recommend that all inspect an
authorized HYUNDAI dealer.
i 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.

it is blown. Spare fuses are provided in
the instrument panel fuse panels (or in
the engine compartment fuse panel).
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 headlights 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.
