EMISSION CONTROL SYSTEMS2
EMISSION CONTROL SYSTEM
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
crankcase. This system supplies 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 and into the induc-
tion system.
H010A01NF-AATYour Hyundai is equipped with an emis-
sion 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 recom-
mended that you have your car inspected
and maintained by an authorized Hyundai
dealer in accordance with the maintenance
schedule in this manual.
Caution for the Inspection and Mainte-
nance 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 com-
pleted, turn the ESC system back on
by pressing the ESC switch again.
H010C01S-AAT2. Evaporative Emission Control (In-
cluding ORVR: Onboard Refuel-
ing Vapor Recovery) SystemThe Evaporative Emission Control Sys-
tem 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 va-
pors into the atmosphere.)CanisterFuel vapors generated inside the fuel tank
are absorbed and stored in the canister.
When the engine is running, the fuel va-
pors absorbed in the canister are drawn
into the induction system through the purge
control solenoid valve.

o Using tires and wheels 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.
o The ABS works by comparing the
speed of the wheels. Tire size can
affect wheel speed. When replac-
ing tires, all 4 tires must use the
same size originally supplied with
the vehicle. Using tires of a differ-
ent size can cause the ABS (Anti-
lock Brake System) and ESC (Elec-
tronic Stability Control) (if in-
stalled) to work irregularly.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 six (6) years of normal
service. Heat caused by not climates
or frequent high loading conditions
can accelerate the aging process.
Failure 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.WARNING:I090C01CM-AATTire Aging

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 should always
be rebalanced if it is removed from the
wheel.
