VEHICLE MAINTENANCE REQUIREMENTS 5 7 EXPLANATION OF SCHEDULED MAINTENANCE ITEMS F060M01A-AAT F060D01TB-AAT F060G01A-AAT o Engine Oil and Filter The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the car is being driven in severe conditions, more frequent oil and filter changes are required. o Fuel Lines, Fuel Hoses and Connections Check the fuel lines, fuel hoses and connections for leakage and damage. Replace any damaged or leaking parts immediately. o Vapor Hose and Fuel Filler Cap The vapor hose and fuel filler cap should be inspected at those intervals specified in the maintenance schedule. Make sure that a new vapor hose or fuel filler cap is correctly replaced. F060C01A-AAT F060F01A-AAT F060H01A-AAT o Fuel Filter A clogged filter can limit the speed at which the vehicle may be driven, damage the emission system and cause hard starting. If an excessive amount of foreign matter accumulates in the fuel tank, the filter may require replacement more frequently. After installing a new filter, run the engine for several minutes, and check for leaks at the connections. Fuel filters should be installed by trained technicians. o Vacuum, Crankcase Ventilation Hoses Inspect the surface of hoses for evidence of heat and/or mechanical damage. Hard and brittle rubber, cracking, tears, cuts, abrasions, and excessive swelling indicate deterioration. Particular attention should be paid to examine those hose surfaces nearest to high heat sources, such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with any heat source, sharp edges or moving component which might cause heat damage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they are secure, and that no leaks are present. Hoses should be replaced immediately if there is any evidence of deterioration or damage. o Air Cleaner Filter A Genuine Hyundai air cleaner filter is recommended when the filter is replaced. F060J01A-AAT o Spark Plugs Make sure to install new spark plugs of the correct heat range. F060N02E-AAT o Valve Clearance Inspect excessive valve noise and/or engine vibration and adjust if necessary. A qualified technician should perform the operation.
