3. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, and then securely close the drain
cock.
4. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
5. Slowly fill the radiator with the proper coolant
mixture (see the "Recommended Engine
Coolant in previous page) until the fluid level
stays up in the radiator neck. And pump the
radiator hose in order to bleed the air.

2. Wrap a thick cloth around the radiator cap
and slowly turn the radiator cap counter-
clockwise without pressing down on it, until
it stops. This relieves any pressure remain-
ing in the cooling system. When you are sure
that all the pressure has been released,
remove the radiator cap by pushing down
and turning counterclockwise.

6. Run the engine at idle until the coolant circu-
lates. If the cooling fan operates and the
coolant starts to circulate, add the coolant to
the reservoir.
7. To bleed the air in the cooling system, repeat
procedure 6 until the cooling fan operates
3~5 times.
8. Replace the radiator cap and turn it until
tightly installed. And then, add coolant to the
reservoir until the level is between "L" and
"F".
9. Stop the engine and check the coolant level
when the engine is cool. The level of the
coolant should be the "L" and "F" lines on the
reservoir. If the level is below the "L" line,
repeat the procedure 4~8 until the level
between "L" and "F".

ant if the level is below the "L" level.
WARNING:
The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the coolant fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition.

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.)

6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform Tire Quality Grading
(UTQG):
Tire manufacturers are required to
grade tires based on three perfor-
mance factors: treadwear, traction
and temperature resistance. For more
information, see Uniform Tire Qual-
ity Grading on page 8-13.
I030D01JM-AATTIRE TERMINOLOGY AND DEFINI-
TIONS
