Brake Fluid Level
The fluid level in the brake fluid reservoir
should be checked periodically. The levelshould be between the "MIN" and "MAX"marks on the side of the reservoir. If the levelis at or below the "MIN" mark, fluid should beadded having carefully cleaned the area sur-rounding the reservoir cap to ensure that dirtis not allowed to enter the system. It shouldbe borne in mind that the brake fluid level willdecrease slightly as the friction linings of thepads and shoes become worn and that this isa normal condition.

BRAKE SYSTEM CHECKING CAUTION:
Correct operation of the braking system is
essential to the safe operation of the vehicle and therefore, any maintenance operationsother than those listed below should beentrusted to a Hyundai dealer.
SG120C2-E
Brake Fluid Recommendations Only brake fluid conforming to DOT 3 or
DOT 4 specifications or higher may be usedin the braking system. Care should be takento observe the instructions and precautionsprinted upon the container.
Fluid level should be within this range

WARNING: The cooling fan is controlled by engine
coolant temperature and may sometimesoperate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so thatyou are not injured by a rotating fan blade.As the engine coolant temperature de-creases, the fan will automatically shutoff. This is a normal condition.
WARNING (Diesel only): Never work on injection system with en-
gine running or within 30 seconds after shutting off engine. High pressure pump,rail, injectors and high pressure pipes aresubject to high pressure even after theengine stopped. The fuel jet produced byfuel leaks may cause serious injury, if it touch the body. People using pacemak-ers should not move than 30cm closer tothe ECU or wiring harness within theengine room while engine is running,since the high currents in the CommonRail system produce considerable mag-netic fields. Fluid Capacity
The total fluid capacity of the transmission unit
is 6.1 litres (1.6 DOHC)/6.7 litres(1.8 DOHC).

SG130B2-E
Adding Fluid
Recommended brake fluid conforming to DOT 3 or DOT 4 should be used. The reservoir capmust be fully tightened to avoid contaminationfrom foreign matter or moisture. CAUTION: Brake fluid is hygroscopic and should never be stored in an unsealed container.Do not allow petroleum base fluid tocontaminate the brake fluid since damageto the rubber seals of the system mayresult. WARNING: Brake fluid will cause rapid and serious damage to paintwork. If accidental spillageoccurs, the affected area must be rinsedwith water immediately. Do not allow brakefluid to come into contact with the eyes or tobe ingested and ensure that fluid is safelystored away form the reach of children.

The clutch fluid level in the master cylinder should be checked when performing other un-der bonnet checks. The system should bechecked for leakage at the same time.

WARNING: Brake fluid is hygroscopic and should never be stored in an unsealed container.The presence of water in the brakingsystem will cause vapour locks and in-crease the possibility of brake fade alongwith promoting corrosion within the brak-ing system. The brake fluid must bechanged at the specified time or mileageinterval to ensure continued safe opera-tion of the system. Brake fluid will causerapid and serious damage to paintwork. Ifaccidental spillage occurs, the affectedarea must be rinsed with water immedi-ately. Do not allow brake fluid to comeinto contact with the eyes or to be in-gested and ensure that fluid is safelystored away form the reach of children.

Ensure that the clutch fluid level is always between the "MAX" and "MIN" level markingson the fluid reservoir. Fill as required. Fluidloss indicates a leak in the clutch systemwhich should be inspected and repaired im-mediately.

Checking the Refrigerant
1. Start the engine and run at idle for several minutes with the refrigeration system run- ning at the coldest setting.
2. Open the bonnet and inspect the sight glass on the top of the receiver dryer.
3. If the refrigerant charge is insufficient, a flow of bubbles will be observed through the sightglass.
4. If the refrigerant charge is satisfactory, no bubbles will be observed through the sightglass.
CAUTION: Running the air conditioning system with a
low refrigerant level may damage the com- pressor.
SG140D1-E
Off Season Maintenance The air conditioning must be run for ten minutes
or so weekly during periods when the systemwould not normally be used to ensure that thecompressor and seals are lubricated. If thisprecaution is not observed the compressor sealsmay become stuck to the compressor shaft anddamaged when the system is next used result-ing in a loss of refrigerant and damage to thecompressor.

INDIVIDUAL CIRCUIT FUSES
The fuse box containing the individual circuit
fuses will be found in the backside of multi box located in the right side of driver. The multi boxis removed by pulling lightly and then releasingthe lid. A fuse rating grid will be found on thereverse side of the cover. In the event of fusefailure, the fuse should be replaced with one ofequivalent rating. A fuse removal tool is pro-vided within the fuse box to facilitate replace-ment.
In the event of a replacement fuse failing shortly
after installation a malfunction within the circuitprotected by that fuse is indicated. The circuitshould be checked by a Hyundai dealer at thefirst available opportunity.

The fusible link prevents damage to the wiring harness in the event of an electrical systemmalfunction. Failure of a fusiblelink is indicativeof a serious overload condition having occurredand therefore the electrical system should bechecked by a Hyundai dealer before a replace-ment link is fitted. WARNING: Under no circumstances should a fusible link be replaced with anything other than anew link of the same rating. The use ofhigher rated links or other means of con-necting the circuit will create a potential firehazard.

ELECTRIC COOLING FANS
WARNING: The cooling fan is controlled by engine coolant temperature and may sometimesoperate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so thatyou are not injured by a rotating fan blade.As the engine coolant temperature decreas-es, the fan will automatically shut off. Thisis a normal condition. The engine cooling fan should operate before the temperature gauge reaches the upper por-tion of the scale and the condenser fan shouldoperate whenever the air conditioning is in use. The power steering fluid level should bechecked daily. To check the power steering fluid level, be sure the ignition is "OFF", then check to makecertain that the power steering fluid level isbetween the "MAX" and "MIN" level markingson the fluid reservoir. NOTE: Grinding noise from power steering pump may be heard immediately after the engineis started in extremely cold condition(below -4°F). If the noise stops during warmup, there is no abnormal function in thesystem. This is due to a power steeringfluid characteristic in extremely cold con-ditions.

WARNING:
Motor vehicle batteries contain sulphuric
acid which is corrosive and poisonous. Hy- drogen gas is emitted from the battery whichis explosive when combined with oxygen.The following precautions must be strictlyobserved to avoid personal injury or dam-age to the vehicle.
o If battery electrolyte is spilled onto skin or into eyes, the effected area must be flushed with copious amounts of water and medicalassistance sought.
o If battery electrolyte is ingested, copious amounts of water or milk followed by an ant-acid (raw egg or milk of magnesia) must bedrunk. Vomiting should not be induced andmedical assistance must be sought.
o Batteries must only be charged in well venti- lated areas from which naked lights or sourc-es of sparks are excluded.
o Ensure that children, pets or other unautho- rized persons are kept away from batteries.
o Do not allow anything to bridge the positive (+) and negative (-) terminals of the battery.
o Never invert the battery.
