Transaxle fluid level checking The vehicle must be parked on level ground with the parking brake firmly applied and the engine at normal oper-ating temperature. (Normal operating temperature will only be achieved when the vehicle has been driven for 6 milesor more). HFC5008
Wipe the dipstick, replace it fully and
promptly remove it again. The fluidlevel should be between the upper and lower marks. CAUTION:
The automatic transaxle unit is a precision engineered assembly andcorrect operation is dependant upon the exclusion of dirt and lint from the unit. Therefore, it is imperative that only lint free cloth (eg nylon) is used for wiping the dipstick andthat the area around the dipstick is thoroughly clean prior to level checking or adding fluid.!
C090A01FC-D With the engine idling and the footbrake
applied, the transaxle selector should be moved from the "P" position through to the "L" position and back to the "N" or "P" position.
Open the bonnet and remove the
transaxle dipstick, remembering thatcare must be exercised to preventinjury occurring through contact with hot or rotating parts of the engine.
This means that the engine, radia-tor, exhaust system etc., are very hot so you should exercise greatcare not to burn yourself during this procedure.
Fluid need only be added if the level is at or below the lower mark and mustnever be increased above the higher mark. If additional fluid is required, this should be poured into the transmissionthrough the dipstick tube with the aid of a suitable funnel.

BRAKE SYSTEM CHECKING
Fluid level should be within this range
C090A03FC
WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the cooling fan so that you are not injured by a rotating fanblade. As the engine coolant tem- perature decreases, the fan will au- tomatically shut off. This is a nor-mal condition. WARNING (Diesel only):
Never work on injection system with
engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious injury, if it contacts the body.
People using pacemakers should
ensure that they keep a distance of30cm from the ECU or wiring har- ness within the engine room whilst engine is running, since the highcurrents in the Common Rail sys- tem produce considerable magnetic fields. SG120A1-E
CAUTION:
Correct operation of the braking
system is essential to the safe op-eration of the vehicle and therefore, any maintenance operations other than those listed below should beentrusted to a Hyundai authorised repairer.

Brake Fluid Level
HFC5005
Petrol engine
G120D02FC
Diesel engine WARNING:
Brake fluid is hygroscopic and should never be stored in an un- sealed container. The presence ofwater in the braking system will cause vapour locks and increase the possibility of brake fade alongwith promoting corrosion within the braking system. The brake fluid must be changed at the specifiedtime or mileage interval to ensure continued safe operation of the sys- tem. Brake fluid will cause rapidand serious damage to paintwork. If accidental spillage occurs, the af- fected area must be rinsed withwater immediately. Do not allow brake fluid to come into contact with the eyes or to be ingested andensure that fluid is safely stored away form the reach of children.
The fluid level in the brake fluid reser-voir should be checked periodically. The level should be between the "MIN" and "MAX" marks on the side of thereservoir. If the level is at or below the "MIN" mark, fluid should be added having carefully cleaned the area sur-rounding the reservoir cap to ensure that dirt is not allowed to enter the system. It should be noted that thebrake fluid level will decrease slightly as the friction linings of the pads and shoes become worn and that this is anormal condition.

CHECKING THE CLUTCH FLUID
The system should be checked for leakage at the same time.Ensure that the clutch fluid level is
always between the "MAX" and "MIN"level markings on the fluid reservoir.Fill as required. Fluid loss indicates a leak in the clutch system which should be inspected and repaired immediately.

Diesel engine HFC5005
G120D02FC
The clutch fluid level in the mastercylinder should be checked when per- forming other under bonnet checks. SG130B2-E
Adding Fluid
Recommended brake fluid conforming
to DOT 3 or DOT 4 should be used.The reservoir cap must be fully tight- ened to avoid contamination from for-eign matter or moisture.
CAUTION:
Brake fluid is hygroscopic and
should never be stored in an un-sealed container. Do not allow pe-troleum base fluid to contaminate the brake fluid since damage to the rubber seals of the system may re-sult.
! WARNING:
Brake fluid will cause rapid and
serious damage to paintwork. If ac- cidental spillage occurs, the affectedarea must be rinsed with water im- mediately. Do not allow brake fluid to come into contact with the eyesor to be ingested and ensure that fluid is safely stored away form the reach of children.

SG140A1-E
Condenser
Ensure that the condenser is periodi- cally inspected and that accumula- tions of dirt, dead insects and leaves etc, are removed to ensure that theefficiency of the system is not im- paired. Care must be exercised to ensure that the condenser fins are notdamaged during cleaning.
SG140C2-E
Checking the Refrigerant
1. Start the engine and run at idle for
several minutes with the refrigera- tion system running at the coldest setting.
2. If the air coming out of the in-dash vents is not cold, have the air con-ditioning system inspected by yourHyundai authorised repairer.
CAUTION:
Running the air conditioning sys- tem with a low refrigerant level may damage the compressor.
! 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 the com-pressor and seals are lubricated. If this precaution is not observed the compressor seals may become stuckto the compressor shaft and damaged when the system is next used result- ing in a loss of refrigerant and damageto the compressor.
SG140B1-E
Compressor Drive Belt The air conditioning compressor drive belt should be checked to ensure free- dom from damage or excessive wearand correct tension. The belt tension is correct when the belt deflects by about 0.3 inches (8 mm) when a forceof 98 N is applied to the belt halfway between the compressor and crank- shaft pulleys. Adjustment of the belt should be en- trusted to a Hyundai authorised re- pairer. CRANK PULLEY

POWER STEERING HOSES
Power steering hoses should be
checked for damage, deterioration and leakage at each service. To check the power steering fluid level,
be sure the ignition is "OFF", thencheck to make certain that the power steering fluid level is between the "MAX" and "MIN" level markings onthe fluid reservoir.
NOTE: Grinding noise from power steering
pump may be heard immediately after the engine is started in ex-tremely cold condition (below -4°F). If the noise stops dur- ing warm up, there is no abnormalfunction in the system. This is due to a power steering fluid character- istic in extremely cold conditions. FLUID RECOMMENDATION
Only automatic transmission fluid
meeting the specification of PSF-3 or Dexron 2 should be used in the power steering system.
