Temperature -A, B & C
The temperature grades are A (the highest), B and C representing the
tyre’s resistance to the generation ofheat and its ability to dissipate heatwhen tested under controlled condi-
tions on a specified indoor laboratorytest wheel.
Sustained high temperature can
cause the material of the tyre to
degenerate and reduce tyre life, and
excessive temperature can lead to
sudden tyre failure. Grades B and A
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by the
law.
WARNING - Tyre
temperature
The temperature grade for this
tyre is established for a tyre 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
tyre failure. This can cause loss
of vehicle control and serious
injury or death.

FUSES
G210000AFD-EA
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
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 bemelted.
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 authorised HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,
and fusible link 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.

Inner panel fuse replacement
1. Turn the ignition switch and all other
switches off.
2. Open the fuse panel cover. 3. Pull the suspected fuse straight out.
Use the removal tool provided in the
engine compartment fuse panel.
4. Check the removed fuse; replace it if it is blown.
5. Push in a new fuse of the same rating, and make sure it fits tightly in the clips.
If it fits loosely, consult an authorised
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, suchas the cigar lighter fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse block in the engine
compartment. If a fuse is blown, it mustbe replaced.
