Maintenance
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Owner’s
Handbook & Warranty Information
booklet in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations.
There are three emission control
systems, as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys-
tem
(3) Exhaust emission control system
In order to ensure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorized retailer of Genesis
Branded products in accordance
with the maintenance schedule in
this manual.
For the Inspection and Maintenance
Test (
with Electronic Stability Control
system)
• To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Control system off by pressing
the ESC switch (ESC OFF light
illuminated).
• After dynamometer testing is
completed, turn the ESC system
back on by pressing the ESC
switch again.
1. Crankcase Emission Control
System
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.
2. Evaporative Emission Control
System Including Onboard
Refueling Vapor Recovery
(ORVR)
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere. The ORVR system is
designed to allow the vapors from
the fuel tank to be loaded into a can-
ister while refueling at the gas sta-
tion, preventing the escape of fuel
vapors into the atmosphere.
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.
