EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport 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 assure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.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 con-
trol 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.
WARNING
The exhaust system and cat-
alytic converter are very hot
during and immediately after
the engine has been running. To
avoid SERIOUS INJURY or
DEATH:
• Do not park, idle, or drive the
vehicle over or near flamma-
ble objects, such as grass,
vegetation, paper, leaves, etc.
A hot exhaust system can
ignite flammable items under
your vehicle.
• Keep away from the exhaust
system and catalytic convert-
er or you may get burned.
Also, Do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle, and do not coat
the vehicle for corrosion con-
trol. It may present a fire risk
under certain conditions.

Maintenance

• Do not operate the engine in con-
fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.
• When the vehicle is stopped in an
open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
• Never sit in a parked or stopped
vehicle for any extended time with
the engine running.
• When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to
the emission control system.Operating precautions for catalyt-
ic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
To prevent damage to the catalytic
converter and to your vehicle, take
the following precautions:
