2017 KIA OPTIMA PLUG-IN HYBRID lock

COOLANT
The high-pressure cooling system has
a reservoir filled with year round anti‐
freeze coolant. The reservoir is filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and be‐ fore traveling to a colder climate.
CAUTION
•When the engine overheats fromlow engine coolant, suddenly add‐ing engine coolant may causecracks in the engine. To preventdamage, add engine coolant slowlyin small quantities.
•Do not drive with no engine cool‐ant. It may cause water pump fail‐ure and engine seizure, etc.
Checking the coolant level
WARNING
nRemoving radiator cap
•Never attempt to remove the radi‐ator cap while the engine is oper‐ating or hot. Doing so might leadto cooling system and engine dam‐age. Also, hot coolant or steamcould cause serious personal in‐jury.
•Turn the engine off and wait untilit cools down. Use extreme carewhen removing the radiator cap.Wrap a thick towel around it, andturn it counterclockwise slowly tothe first stop. Step back while thepressure is released from the cool‐ing system.When you are sure all the pressurehas been released, press down onthe cap, using a thick towel, andcontinue turning counterclockwiseto remove it.
(Continued)
(Continued)
•Even if the engine is not operating,do not remove the radiator cap orthe drain plug while the engine andradiator are hot. Hot coolant andsteam may still blow out underpressure, causing serious injury.
The engine coolant and/or inverter
coolant level is influenced by the hybrid system temperature. Before checking
or refilling the engine coolant and/or in‐
verter coolant, turn the hybrid vehicle off.
WARNING
The electric motor (cool‐ing fan) is controlled byengine coolant tempera‐ture, refrigerant pressureand vehicle speed. It maysometimes operate evenwhen the engine is notrunning.

NOTICE
We recommend that when replacing
tires, use the same originally sup‐
plied with the vehicles.
If not, that affects driving perform‐
ance.
CAUTION
When replacing the tires, recheckand tighten the wheel nuts afterdriving about 50 km (31 miles) andrecheck after driving about 1,000 km(620 miles).If the steering wheel shakes or thevehicle vibrates while driving, thetire is out of balance. Align the tirebalance. If the problem is not solved,we recommend that you contact anauthorized Kia dealer.
WARNING
nReplacing tires
(Continued)
(Continued)
To reduce the chance of serious orfatal injuries from an accidentcaused by tire failure or loss of vehi‐cle control:•Replace tires that are worn, showuneven wear, or are damaged.Worn tires can cause loss of brak‐ing effectiveness, steering control,and traction.
•Do not drive your vehicle with toolittle or too much pressure in yourtires. This can lead to uneven wearand tire failure.
•When replacing tires, never mix ra‐dial and bias-ply tires on the samecar. You must replace all tires (in‐cluding the spare) if moving fromradial to bias-ply tires.
•Using tires and wheels other thanthe recommended sizes couldcause unusual handling character‐istics and poor vehicle control, re‐sulting in a serious accident.
(Continued)
(Continued)
•Wheels that do not meet Kia’sspecifications may fit poorly andresult in damage to the vehicle orunusual handling and poor vehiclecontrol.
•The ABS works by comparing thespeed of the wheels. The tire sizeaffects wheel speed. When replac‐ing tires, all 4 tires must use thesame size originally supplied withthe vehicle. Using tires of a differ‐ent size can cause the ABS (Anti-lock Brake System) and ESC (Elec‐tronic Stability Control) to work ir‐regularly.
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new wheels are equivalent to the original factory
units in diameter, rim width and offset.

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.
Fuse switch

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

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.
