If the vehicle is operated in extreme- ly dusty or sandy areas, replace theelement more often than the usualrecommended intervals. (Refer to“Maintenance under severe usageconditions” in this chapter.)
• Do not drive with the filter removed; this will result in exces-
sive engine wear.
• When replacing th e air cleaner fil-
ter, be careful that dust or dirt does

$$!!"#"#$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
emission regulations.
There are three emission control
systems which are 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
car inspected and maintained by an
authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.
1. Crankcase emission control systemThe 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 controlsystemThe Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.CanisterFuel 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.Purge Control Solenoid Valve(PCSV)The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated 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.
