VEHICLE MAINTENANCE REQUIREMENTS 5-7
6ZF070D1-A
o Manual transaxle oil Inspect the manual transaxle oil according to
the maintenance schedule. NOTE: If the oil level is low, check for possible
leaks before adding oil. Do not overfill.
6ZF070H1-A
o Rear brake drums and linings/ parking brake
Check the rear brake drums and linings for
scoring, burning, leaking fluid, broken parts, and excessive wear. Inspect the parkingbrake system including the parking brakelever and cables. For detailed service proce-dures, refer to the Shop Manual.
6ZF070J1-A
o Brake pads, calipers and rotors Check the pads for excessive wear, discs for
run out and wear, and calipers for fluid leak-age.
6ZF070K1-A
o Exhaust pipe and muffler Visually inspect the exhaust pipes, mufflerand hangers for cracks, deterioration, or dam-age. Start the engine and listen carefully forany exhaust gas leakage. Tighten connec-tions or replace parts as necessary.
F070E03A-AAT
o Automatic transaxle fluid The fluid level should be in the "HOT" range
of the dipstick, after engine and transaxle areat normal operating temperature. Check theAutomatic Transaxle Fluid level with the en-gine running and the transaxle in neutral, withthe parking brake properly applied. Use DIA-MOND ATF SP- III or SK ATF SP- III when
adding or changing fluid. 6ZF070F1-A
o Brake hoses and lines Visually check for proper installation, chafing, cracks, deterioration and any leakage. Replaceany deteriorated or damaged parts immediately.
6ZF060H1-A
o Air cleaner filter A Genuine Hyundai air cleaner filter is recom-
mended when filter is replaced.
6ZF060J1-A
o Spark plugs Make sure to install new spark plugs of the
correct heat range.
6ZF070B1-A
o Cooling system Check the cooling system part, such asradiator, coolant reservoir, hoses and con-nections for leakage and damage. Replaceany damaged parts. 6ZF070G2-A
o Brake fluid Check brake fluid level in the brake fluidreservoir. The level should be between "MIN"and "MAX" marks on the side of the reservoir.Use only hydraulic brake fluid conforming toDOT 3 or DOT 4.
6ZF070C1-A
o Engine coolant The coolant should be changed at theintervals specified in the maintenance sched-ule.
F060N01E-AAT
o Valve Clearance Inspect excessive valve noise and/or enginevibration and adjust if necessary. A qualifiedtechnician should perform the operation.
Valve Clearance
Intake valves: 0.0067 ~ 0.0091 in. (0.17 ~ 0.23mm)
Exhaust valves: 0.0098 ~ 0.0122 in. (0.25 ~ 0.31mm)

EMISSION CONTROL SYSTEM
7-2
It is of the utmost importance that the following information is read and understood by thevehicle operator in order to prevent operationalproblems arising from damage to the catalyst.Damage to the catalyst will result if contamina-tion occurs through the use of leaded fuel.Whilst the vehicle is fitted with a reduced diam-eter filler neck to prevent charging of the fueltank with a leaded fuel pump nozzle, it ispossible that the use of funnels or jerry cans willpermit leaded fuel to be introduced into the fueltank.The catalyst is intolerant of unburnt fuel andtherefore if an engine misfire condition exists,damage to the catalyst will occur. It is impera-tive that if a misfire condition develops, thevehicle is immediately presented to a Hyundaidealer for rectification. Similarly, the practice ofcertain ignition system diagnosis procedureswhich involve inducing a misfire (cylinder powerbalance tests for example) may result in cata-lyst damage.For these reasons, it is advisable that theexhaust gas emission be tested at each routineservice with a gas analyzer having a Hydrocar-bon measuring facility to ensure continuedreliability of the catalyst.Push or tow starting of the vehicle is to beavoided since unburnt fuel may be enter thecatalyst and result in damage. (Note, it isimpossible to push or tow start a Hyundaimodel equipped with fuel injection since thefuel pump safety interlock will prevent the pumpfrom operating under these conditions).
Operation of the catalyst involves extremelyhigh temperatures being attained within thecatalytic convertor, and although the convertoris fitted with heat shields, it is important that thevehicle is not parked over combustible or vola-tile material which may result in fire.If the above precautions are not adhered to andthe catalyst becomes inoperative, the resultantincrease in core temperature will result in a"melt down" where the catalyst core will meltand subsequently may block the exhaust sys-tem.Due to the fragile nature of the catalyst ele-ment, it is important that damage does notoccur when the vehicle is raised by means of agarage jack. Care must also be exercised toavoid driving over road hazards or debris whichmay cause damage to the catalyst element.
H020D01S-GAT CATALYTIC CONVERTER ; For a diesel engine All Hyundai vehicles are equipped with oxida- tion type catalytic converter to reduce the car-bon monoxide, hydrocarbons and particulatecontained in the exhaust gas.
H020C01S-GAT EGR SYSTEM ; For a diesel engine This system helps control oxides of nitrogen by recirculating a part of the exhaust gas into theengine.
