2017 KIA OPTIMA PLUG-IN HYBRID engine

If it fits loosely, we recommend that
you consult an authorized Kia 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 taillights, stop lights, courtesy lamp, day time running
lights (D.R.L) do not work and the fuses
are OK, check the fuse panel in the en‐ gine compartment. If a fuse is blown, it
must be replaced.

Always, put the fuse switch at the ON
position. If you move the switch to the OFF posi‐
tion, some items such as audio and dig‐
ital clock must be reset and transmitter
(or smart key) may not work properly.
If the fuse switch is in OFF, a warning sign will illuminate on the dashboard.
CAUTION
•Put all switches in ON when driv‐ing.
•If the vehicle remains idle for over1 month, put all switches in OFF toprevent the batteries from beingdischarged.
•Excluding long-term parking forover 1 month, the contact pointsof switches may wear out uponextensive use. Please refrain fromexcessive use of switches.
Engine compartment fuse
replacement
1. Turn the ignition switch and all oth‐ er switches off.
2. Remove the fuse panel cover by pressing the tab and pulling the
cover up. When the blade type fuse
is disconnected, remove it by using
the clip designed for changing fuses
located in the engine room fuse
box. Upon removal, securely insert
reserve fuse of equal quantity.
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 samerating, and make sure it fits tightly
in the clips. If it fits loosely, we rec‐
ommend that you consult an au‐
thorized Kia dealer.
CAUTION
After checking the fuse panel in theengine compartment, securely installthe fuse panel. If not, cover throughthe audible clicking sound. Electricalfailures may occur from water con‐tact.
Multi fuse
If the multi fuse is blown, it must be re‐
moved as follows: 1. Disconnect the negative battery cable.
2. Remove the nuts shown in the pic‐ ture above.
3. Replace the fuse with a new one of the same rating.
4. Reinstall in the reverse order of re‐ moval.
NOTICE
If the multi fuse is blown, we recom‐
mend that you consult an author‐
ized Kia dealer.
Main fuse
If the main fuse is blown, it must be re‐
moved as follows: 1. Turn off the engine.
2. Disconnect the negative battery cable.
3. Remove the nuts shown in the pic‐ ture above.

4. Replace the fuse with a new one ofthe same rating.
5. Reinstall in the reverse order of re‐ moval.
NOTICE
The electronic system may not
function correctly even when the
engine room and internal fuse box's
individual fuses are not disconnec‐
ted. In such case the cause of the
problem may be disconnection of
the main fuse (BFT type), which is
located inside the positive battery
terminal (+) cap. Since the main fuse
is designed more intricately than
other parts, please visit the nearest
Kia dealer and service center.
CAUTION
Visually inspect the battery cap forsecure closing. If the battery cap isnot securely latched, the electricalsystem may be damaged to due in‐flux of moisture into the system.

CAUTION
•Water washing in the engine com‐partment including high pressurewater washing may cause the fail‐ure of electrical circuits located inthe engine compartment.
•Never allow water or other liquidsto come in contact with electrical/electronic components inside thevehicle as this may damage them.
Waxing
Wax the vehicle when water will no lon‐
ger bead on the paint. Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufactur‐
er’s instructions. Wax all metal trim to protect it and to maintain its luster.
Removing oil, tar, and similar materials
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 waxing.
Do not apply wax on embossed unpain‐
ted unit, as it may tarnish the unit.
CAUTION
•Wiping dust or dirt off the bodywith a dry cloth will scratch thefinish.
•Do not use steel wool, abrasivecleaners, acid detergents or strongdetergents containing high alkalineor caustic agents on chrome-plat‐ed or anodized aluminum parts.This may result in damage to theprotective coating and cause dis‐coloration or paint deterioration.
Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly rust and may develop into a major re‐
pair expense.
NOTICE
If your vehicle is damaged and re‐
quires any metal repair or replace‐
ment, be sure the body shop applies
anti-corrosion materials to the parts
repaired or replaced.
Bright-metal maintenance
• To remove road tar and insects, use a tar remover, not a scraper or other
sharp object.
• To protect the surfaces of bright- metal parts from corrosion, apply a
coating of wax or chrome preserva‐
tive and rub to a high luster.
• During winter weather or in coastal areas, cover the bright metal parts
with a heavier coating of wax or preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.

EMISSION CONTROL SYSTEM (IF EQUIPPED)
The emission control system of your vehicle is covered by a written limited
warranty. Please see the warranty in‐
formation contained in the Warranty & Maintenance book in your vehicle.
Your vehicle is equipped with an emis‐
sion control system to meet all applica‐
ble emission regulations.
There are three emission control sys‐ tems, as follows. 1. Crankcase emission control system
2. Evaporative emission control sys‐ tem
3. Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your vehi‐ cle inspected and maintained by an au‐
thorized Kia dealer in accordance with
the maintenance schedule in this man‐ ual.
Caution for the Inspection and Mainte‐nance Test (With Electronic StabilityControl (ESC) system)
•To prevent the vehicle from misfiringduring dynamometer testing, turnthe Electronic Stability Control (ESC)system off by pressing the ESCswitch. •
After dynamometer testing is com‐pleted, turn the ESC system back onby pressing the ESC switch again.
1. Crankcase emission control
system
The positive crankcase ventilation sys‐
tem is employed to prevent air pollu‐ tion caused by blow-by gases being
emitted from the crankcase. This sys‐
tem supplies fresh filtered air to the crankcase through the air intake hose.
Inside the crankcase, the fresh air mix‐
es with blow-by gases, which then pass through the PCV valve into the induc‐
tion system.
2. Evaporative emission control
system
The Evaporative Emission Control Sys‐
tem is designed to prevent fuel vapors from escaping into the atmosphere.
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the on‐ board canister. When the engine is run‐
ning, the fuel vapors absorbed in the
canister are drawn into the surge tank through the purge control solenoid
valve.
Purge control solenoid valve (PCSV)
The purge control solenoid valve is con‐ trolled by the Engine Control Module
(ECM); when the engine coolant tem‐
perature is low during idling, the PCSV closes so that evaporated 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 con‐
trols exhaust emissions while maintain‐
ing good vehicle performance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could affect
its performance, safety or durability and may even violate governmental
safety and emissions regulations.
In addition, damage or performance
problems resulting from any modifica‐ tion may not be covered under warran‐
ty.
