Maintenance
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.

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.

State of charge
The state of charge (SOC) gauge
indicates the hybrid battery's charge
level. If the SOC is near Low (L)
level, the vehicle automatically oper-
ates the engine to charge the battery.
The gauge will rarely approach the
High (H) level. This is normal and is
not an indication of a malfunction.
However, if the service indicator and
MIL(Malfunction indicator lamp) turn
on when the State of Charge(SOC)
is near L, have your vehicle checked
by an authorized Kia dealer immedi-
ately.

CAUTION- Extendedcranking
Do not crank the engine for aprolonged period of time with-out the engine starting. Thiscould result in damage to theHEV battery and becomingtotally discharged.

Starting the Hybrid System
1.Carry the smart key into the vehi-cle.
2.Make sure the parking brake is firmly applied.
3.Place the shift lever in the P(Park) position.
In N (neutral) position, the engine
(hybrid system) will not start.
4.Depress the brake pedal.
5.Press the engine start/stop button.
6.The engine should be started with- out pressing the accelerator. In
extremely cold weather or after the
vehicle has not been operated for
several days, let the engine warm
up without depressing the acceler-
ator.
• Even if the smart key is in thevehicle, it muse be within range of
the antenna before the engine
(hybrid system) will not start.
ton is in the ACC or ON position,
if any door is open, the system
checks for the smart key. If the
smart key is not in the vehicle, the
warning, "Key is not in vehicle"
will come on, and if all doors are
closed, the chime will also sound
for about 5 seconds. The indica-
tor will turn off while the vehicle is
moving. Keep the smart key in the
vehicle when using the ACC posi-
tion or if the vehicle engine is on. If the starting procedure is fol-
lowed, the "READY" symbol on
the instrument cluster will turn on.
