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.

Maintenance
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.

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.

Waxing
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-
ing.CAUTION
• Wiping dust or dirt off the
body with a dry cloth will
scratch the finish.
• Do not use steel wool, abra-
sive cleaners, or strong deter-
gents containing highly alka-
line or caustic agents on
chrome-plated or anodized
aluminum parts. This may
result in damage to the pro-
tective coating and cause dis-
coloration or paint deteriora-
tion.
CAUTION
• Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical
circuits or engine and related
part located in the engine
compartment.
• Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents and air duct inside the
vehicle as this may damage
them.

Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.3. Exhaust emission control
system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Vehicle modifications
• This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or perform-
ance problems resulting from any
modification may not be covered
under warranty.
• If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust gas precautions
(carbon monoxide)
• Carbon monoxide can be present
with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately.
WARNING - Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
