7
Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-ment more often than the usual recom-mended intervals. (Refer to“Maintenance under severe usage condi-tions” in this section.)
Filter inspection
The climate control air filter should be
replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it by per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.
Filter replacement
1. Open the glove box and remove the support strap (1).
CAUTION
Do not drive with the air cleaner removed; this will result in exces-sive engine wear.
When removing the air cleaner fil- ter, be careful that dust or dirtdoes not enter the air intake, ordamage may result.
Use a HYUNDAI genuine part. Use of non-genuine parts could dam-age the air flow sensor.

2. With the glove box open, remove thestoppers by turning them counter-
clockwise on both sides. 3. Remove the climate control air filter
cover while pressing the lock on the
right of the cover. 4. Replace the climate control air filter.
5. Reassemble in the reverse order of
disassembly.
✽ ✽NOTICE
When replacing the climate control air
filter install it properly. Otherwise, the
system may produce noise and the effec-
tiveness of the filter may be reduced.

EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Owner’s
Handbook & Warranty Information book-
let in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations.
There are three emission control sys-
tems, as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of
the emission control systems, it is rec-
ommended that you have your car
inspected and maintained by an author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manu-
al.Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch.
After dynamometer testing is com- pleted, turn the ESC system back on
by pressing the ESC switch again.
1. Crankcase emission control system
The positive crankcase ventilation sys-
tem 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(including ORVR: Onboard
Refueling Vapor Recovery)
system
The Evaporative Emission Control
System is designed to prevent fuel vapors
from escaping into the atmosphere.
(The ORVR system is designed to allow
the vapors from the fuel tank to be
loaded into a canister while refueling at
the gas station, 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 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 tempera-
ture 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.
