SG140D1-E Off Season Maintenance The air conditioning must be run for ten minutes or so weekly during peri- ods when the system would not nor- mally be used to ensure that thecompressor and seals are lubricated. If this precaution is not observed the compressor seals may become stuckto the compressor shaft and dam- aged when the system is next used resulting in a loss of refrigerant anddamage to the compressor. SG140B1-E
Compressor Drive Belt The air conditioning compressor drive
belt should be checked to ensurefreedom from damage or excessive wear and correct tension. The belt tension is correct when the belt de-flects by about 0.3 inches (8 mm) when a force of 98 N is applied to the belt halfway between the compressorand crankshaft pulleys. Adjustment of the belt should be entrusted to a Hyundai dealer.

o If battery electrolyte is spilled onto
skin or into eyes, the effected area must be flushed with copious amounts of water and medical assis-tance sought.
o If battery electrolyte is ingested, copious amounts of water or milkfollowed by an ant-acid (raw egg ormilk of magnesia) must be drunk. Vomiting should not be induced and medical assistance must besought.
o Batteries must only be charged in well venti-lated areas from which naked lights or sources of sparks are excluded.
o Ensure that children, pets or other unautho-rized persons are keptaway from batteries.
o Do not allow anything to bridge the
positive (+) and negative (-) termi-nals of the battery.
o Never invert the battery.
The battery fitted during production isof the "Maintenance Free" type.
ELECTRIC COOLING FANS
!
YG210A1-E
WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even whenthe engine is not running. Do not touch the radiator fan until it is completely stopped.As the coolant temperature de-creases the fan will automaticallyshut off. This is a normal condi- tion.
Checking Engine Cooling Fan The engine cooling fan should auto- matically come on if the engine cool-ant temperature is high.
Checking Condenser Cooling Fan The condenser cooling fan (in front of the condenser) should come on auto- matically whenever the air conditioneris in operation.
POWER STEERING HOSES
YG220A1-E It is suggested that you check the power steering hose connections for fluid leakage at those intervals speci- fied in the vehicle maintenance sched-ule in Section 5. The power steering hoses should be replaced if there are severe surface cracking, pulling, scuff-ing or worn spots. Deterioration of the hoses could cause premature failure. NOTE: The power steering pump may be noisy when the engine is firststarted in the extreme cold (-4°F). This noise is not abnormal and will stop as the engine warms up.If the power steering pump contin- ues to be noisy after the engine has warmed up, have it inspectedby your Authorized Hyundai Dealer.

7EMISSION CONTROL SYSTEMS
2
SH010A1-E (Not all models) Depending upon the market for which the vehicle is destined, the emission control system will comprise one or more of the following emission controldevices.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control systemIn order that the proper functioning of the emission control systems may be ensured, it is recommended that the vehicle is inspected and maintainedby an authorized Hyundai dealer in accordance with the maintenance schedule in this manual. EMISSION CONTROL SYS- TEMS
SH010B1-E
1. CRANKCASE EMISSION CON- TROL SYSTEM The positive crankcase ventilation system is employed to prevent air pollution caused by blow-by gases being emitted from the crankcase byintroducing fresh air to the crankcase through the air cleaner where this mixes with blow-by gases and thenpasses through the PCV valve into the intake manifold from where it sub- sequently enters the combustionchamber and is burned.
SH010C1-E
2. EVAPORATIVE EMISSION
CONTROL SYSTEM
The Evaporative Emission Control
System is designed to prevent fuelvapours from escaping into the atmo-sphere through the fuel tank ventila- tion system. SH010D1-E
3. EXHAUST EMISSION
CONTROL SYSTEM
The exhaust emission control system
is a highly effective system which controls exhaust emission while main- taining good vehicle performance. Whilst the engine is not running, fuel vapours generated inside the fuel tankare absorbed and stored in a char- coal canister. When the engine is started, the vapours stored in thecanister are drawn into the induction system through the purge control so- lenoid valve and are subsequentlyburned.The purge control solenoid valve iscontrolled by the ECU; when the en-gine coolant temperature is low or the engine is idling, the purge control valve is closed and fuel vapours re-main stored in the canister. Under normal running conditions when the engine is warm, the valve opens andthe vapours are drawn into the inlet tract and subsequently burned in the combustion chamber.
