EMISSION CONTROL SYSTEMS2
EMISSION CONTROL
SYSTEMS
H010B01A-AAT1. Crankcase Emission Control SystemThe positive crankcase ventilation system is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. 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.
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 solenoid
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 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.H010D01A-AAT3. Exhaust Emission Control
SystemThe Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle per-
formance.
H010A01NF-AATYour Hyundai 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 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 recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
Caution for the Inspection and Maintenance
Test (With Electronic Stability Control (ESC)
system)
o To prevent the vehicle from misfiring
during dynamometer testing, turn the
Electronic Stability Control (ESC) sys-
tem off by pressing the ESC switch.
o After dynamometer testing is completed,
turn the ESC system back on by pressing
the ESC switch again.
H010C01S-AAT2. Evaporative Emission Control (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) SystemThe 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, pre-
venting the escape of fuel vapors into the
atmosphere.)

I090B02JM-AATTIRE MAINTENANCE
In addition to proper inflation, correct
wheel alignment helps to decrease tire
wear. If you find a tire is worn unevenly,
have your dealer check the wheel align-
ment.
When you have new tires installed,
make sure they are balanced. This will
increase vehicle ride comfort and tire
life. Additionally, a tire shoud always be
rebalanced if it is removed from the
wheel. o Using tires and wheel other than
the recommended sizes could
cause unusual handling charac-
teristics and poor vehicle control,
resulting in a serious accident.
o Wheels that do not meet Hyundai's
specifications may fit poorly and
result in damage to the vehicle or
unusual handling and poor ve-
hicle control.WARNING:WARNING:
Tires degrade over time, even when
they are not being used. Regardless
of the remaining tread, it is recom-
mended that tires tread, It is recom-
mended that tires generally be re-
placed after 6 years of normal ser-
vice. Heat caused by not climates or
frequent high loading Conditions can
accelerate the aging process. Fail-
ure to follow this Warning can result
in sudden tire failure, which could
lead to a loss of control and an
accident involving serious injury or
death.
