FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 fuse panels, one
located in the driver’s side panel bol-
ster, the other in the engine compart-
ment 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 melt.
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 imme-
diately consult an authorized Kia
dealer.
Three kinds of fuses are used: bladetype for lower amperage rating, car-tridge type, and multi fuse for higheramperage ratings.
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 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 - Fuse replace-
ment
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.

3. Pull the suspected fuse straightout. Use the fuse puller 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 youmay not need for operating the vehi-cle, such as the cigar lighter fuse.
If the headlights or other electrical
components do not work and the
fuses are OK, check the fuse block 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
transmitter (or smart key) may not
work properly.

NOTICE
If you need to park your vehicle for
prolonged periods more than 1
month, move the transportation fuse
switch to the OFF position to pre-
vent the battery being discharged.
Engine compartment panel fuse
replacement
1. Turn the hybrid system and all other switches off.
2. Remove the fuse box cover by pressing the tap and pulling up the
cover.
3. Check the removed fuse; replace it if it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment fuse panel.
4. 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.

CAUTION - Fuse panel
covers
After checking the fuse panel inthe engine compartment,securely install the fuse panelcover to prevent electrical fail-ures which may occur fromwater leaking in.
CAUTION
Always place the transporta- tion fuse switch in the ON posi-tion while driving the vehicle.
Do not move the transportation fuse switch repeatedly. Thefuse switch may be worn out.

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 modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation 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.

Recommended SAE viscosity
numberEngine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather.Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle
will be operated in before the next oil
change. Proceed to select the rec-
ommended oil viscosity from the
chart.
CAUTION
Always be sure to clean the area
around any filler plug, drainplug, or dipstick before check-ing or draining any lubricant.This is especially important industy or sandy areas and whenthe vehicle is used on unpavedroads. Cleaning the plug anddipstick areas will prevent dirtand grit from entering theengine and other mechanismsthat could be damaged.

Specifications & Consumer information
For better fuel economy, it is recommended to use the engine oil of a
viscosity grade SAE 5W-20 (API SM / ILSAC GF-4). However, if the
engine oil is not available in your country, select the proper engine oil
using the engine oil viscosity chart.
