Use a high quality ethylene-glycol coolant in a 50/50 mix with water. The engine coolant should be compatiblewith aluminum engine parts. Addi- tional corrosion inhibitors or additives should not be used. The cooling sys-tem must be maintained with the cor- rect concentration and type of engine coolant to prevent freezing and corro-sion. Never allow the concentration of antifreeze to exceed the 60% level or go below the 35% level, or damage tothe cooling system may result. For proper concentration when adding or replacing the engine coolant, refer tothe following table. G050C02E

G050C01A-GAT
To Check the Coolant Level
The coolant level can be seen on the side of the plastic coolant reservoir. The level of the coolant should bebetween the "L" and "F" lines on the reservoir when the engine is cold. If the level is below the "L" mark, addengine coolant to bring it up between "L" and "F". If the level is low, inspect for coolant leaks and recheck thefluid level frequently. If the level drops again, visit your Hyundai dealer for an inspection and diagnosis of the rea-son.

SPARK PLUGS
G060A01L
G060B02S-GAT
REPLACING THE SPARK PLUGS (Gasoline Engine)
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenances schedule in Sec- tion 5 or whenever engine perfor-mance indicates they should be changed. Symptoms that suggest poor spark plug performance include en-gine misfiring under load, loss of fuel economy, poor acceleration, etc. When spark plugs are replaced, al-ways use spark plugs recommended by Hyundai. The use of other spark plugs can result in loss of perfor-mance, radio interference or engine damage.Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)
NOTE: When replacing the spark plugs, genuine Hyundai replacement partsare recommended. Recommended Spark Plugs:

WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even when theengine is not running. Use extreme caution when working near the blades of the cooling fan so thatyou are not injured by a rotating fan blade. As the engine coolant tem- perature decreases, the fan will au-tomatically shut off. This is a nor- mal condition.

CHECKING THE BRAKES
G120A01A-AAT
! CAUTION:
Because brakes are essential to
the safe operation of the car, it is suggested that they be checked and inspected by your Hyundai dealer. The brakes should bechecked and inspected for wear at those intervals specified in the vehicle maintenance schedule inSection 5.
WARNING (Diesel only):
Never work on injection system
with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec-tors and high pressure pipes are subject to high pressure even af- ter the engine stopped. The fuel jetproduced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers shouldnot move than 30cm closer to the ECU or wiring harness within the engine room while engine is run-ning, since the high currents in the Common Rail system produce considerable magnetic fields.
WARNING:
The cooling fan is controlled byengine coolant temperature and may sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the cooling fan so that you are not injured by arotating fan blade. As the engine coolant temperature decreases, the fan will automatically shut off. Thisis a normal condition.

Fluid level should be within this range
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipstick tube until the level reaches the "HOT" range. Do not overfill.

CHECKING ELECTRIC COOLING FANS

WARNING:
The cooling fan is controlled by
engine coolant temperature and may sometimes operate even whenthe engine is not running. Use extreme caution when working near the blades of the cooling fan,so that you are not injured by a rotating fan blade. As the engine coolant temperature decreases thefan will automatically shut off. This is a normal condition.
o When lifting a plastic-cased bat-
tery, excessive pressure on the case may cause battery acid toleak, resulting in personal injury. Lift with a battery carrier or with your hands on opposite corners.
o Never attempt to charge the bat- tery when the battery cables areconnected.
o The electrical ignition system works with high voltage. Never touch these components with the engine running or the ignition switched on.
The power steering fluid level should
be checked regularly.

7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEMS
H010A01A-GAT
(If installed)
Your Hyundai is equipped with an
emission control system to meet all requirements of the Emission prohibi- tion rules of your province.
There are three emission control sys-
tems 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 carinspected and maintained by an au- thorized Hyundai dealer in accordance with the maintenance schedule in thismanual. H010B01A-AAT
1. Crankcase Emission Control
System
The positive crankcase ventilation
system is employed to prevent airpollution caused by blow-by gasesbeing emitted from the crankcase. This system supplies fresh filtered air to the crankcase through the air in-take hose. Inside the crankcase, the fresh air mixes with blow-by gases, then passes through the PCV valveinto the induction system.
H010C02E-GAT
2. Evaporative Emission
Control System
The Evaporative Emission Control
System is designed to prevent fuel vapors from escaping into the atmo- sphere. Canister
While the engine is inoperative, fuel
vapors generated inside the fuel tank are absorbed and stored in the canis-ter. When the engine is running, the fuel vapors absorbed in the canister are drawn into the induction system through the purge control solenoid valve. Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is
controlled by the Engine Control Mod- ule (ECM); when the engine coolant temperature is low during idling, thePCSV closes so that evaporated fuel is not taken into the engine. After the engine warms-up during ordinary driv-ing, the PCSV opens so as to intro- duce evaporated fuel to the engine.
H010D01A-AAT
3. Exhaust Emission Control
System
The Exhaust Emission Control Sys-
tem is a highly effective system which controls exhaust emissions while maintaining good vehicle performance.
