2017 KIA OPTIMA PLUG-IN HYBRID maintenance schedule

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.
