Snow tires
If you equip your car with snow tires,
they should be the same size and
have the same load capacity as the
original tires. Snow tires should be
installed on all four wheels; other-
wise, poor handling may result.
Snow tires should carry 28 kPa (4
psi) more air pressure than the pres-
sure recommended for the standard
tires on the tire label on the driver's
side of the center pillar, or up to the
maximum pressure shown on the tire
sidewall, whichever is less.
Do not drive faster than 120 km/h (75
mph) when your car is equipped with
snow tires.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.

FUSES
G210000AMG
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
another 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 KIA 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 circuitand 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 authorized KIA
dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you maynot need for operating the vehicle, such as the cigarette lighter fuse.
If the headlights or other electrical com-
ponents 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.

Memory fuse
Your vehicle is equipped with a memory
fuse to prevent battery discharge if your
vehicle is parked without being operated
for prolonged periods. Use the following
procedures before parking the vehicle for
prolonged periods.
1. Turn off the engine.
2. Turn off the headlights and tail lights.
3. Open the driver’s side panel cover andpull up the memory fuse.
✽ ✽NOTICE
• If the memory fuse is pulled up from
the fuse panel, the warning chime,
audio, clock and interior lamps, etc.,
will not operate. Some items must be
reset after replacement. Refer to
“Battery” in this section.
• Even though the memory fuse is pulled up, the battery can still be dis-
charged by operation of the head-
lights or other electrical devices.
