WHAT TO DO IN AN EMERGENCY 3-7
STA3071H
WARNING: Wheel and wheel covers may have sharp edges. Handle them carefully to avoid pos- sible severe injury. Before putting the wheel into place, be sure that there is nothing on the hub or wheel (such as mud, tar, gravel, etc.) that interferes with the wheel from fitting solidly against the hub. If there is, remove it. If there is not good contact on the mounting surface between the wheel and hub, the wheel nuts could loosen and cause the loss of a wheel. Loss of a wheel may result in loss of control of the vehicle. This may cause serious injury or death. D060H02A-AAT 7. Re-install Wheel Nuts To reinstall the wheel cover, hold it on the studs, put the wheel nuts on the studs and tighten them finger tight. The nuts should be installed with their small diameter ends directed inward. Jiggle the tire to be sure it is completely seated, then tighten the nuts as much as possible with your fingers again.
Lower the car to the ground by turning the wheel nut wrench counterclockwise. Then position the wrench as shown in the drawing and tighten the wheel nuts. Be sure the socket is seated com- pletely over the nut. Do not stand on the wrench handle or use an extension pipe over the wrench handle. Go around the wheel tightening every other nut until they are all tight. Then double-check each nut for tightness. After changing wheels, have a technician tighten the wheel nuts to their proper torque as soon as possible. Wheel nut tightening torque: Steel wheel & aluminium alloy wheel: 900-1,100 kg.cm (65-80 lb.ft)

F060A01A-AAT EXPLANATION OF SCHEDULED MAINTENANCE ITEMS F060M01A-AAT o Engine Oil and FilterThe engine oil and filter should be changed at
the intervals specified in the maintenance sched- ule. If the car is being driven in severe condi- tions, more frequent oil and filter changes are required. F060B01A-AAT
o Drive BeltsInspect all drive belts for evidence of cuts, cracks, excessive wear or oil saturation andreplace if necessary. Drive belts should be checked periodically for proper tension and adjusted as necessary. F060C01A-AAT
o Fuel FilterA clogged filter can limit the speed at which the vehicle may be driven, damage the emission system and cause hard starting. If an exces- sive amount of foreign matter accumulates in the fuel tank, the filter may require replacement more frequently. After installing a new filter, run the engine forseveral minutes, and check for leaks at the connections. Fuel filters should be installed by trained technicians.
F060D01TB-AAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and connec- tions for leakage and damage. Replace any damaged or leaking parts immediately. WARNING (Diesel only): Never work on injection system with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec- tors and high pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers should not move than 30cm closer to the ECU or wiring har- ness within the engine room while engine is running, since the high currents in the Com- mon Rail system produce considerable mag- netic fields. F060E01A-AAT
o Timing BeltInspect all parts related to the timing belt for damage and deformation. Replace any dam- aged parts immediately. F060G01A-AAT
o Vapor Hose and Fuel Filler Cap The vapor hose and fuel filler cap should be
inspected at those intervals specified in themaintenance schedule. Make sure that a new vapor hose or fuel filler cap is correctly re- placed.
F060F01A-AAT
o Vacuum, Crankcase Ventilation
Hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brit-tle rubber, cracking, tears, cuts, abrasions, and excessive swelling indicate deterioration. Par- ticular attention should be paid to examining those hose surfaces nearest to high heat sourc- es, such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heatsource, 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.

ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of lubricat-
ing and cooling the inside of the engine.
Engine oil consumption It is normal that an engine should consume
some engine oil while normal driving. The cause of oil consumption in a normal engine are asfollows;
o Engine oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in thecylinder. High negative pressure generated
during engine operation sucks some of theoil into the combustion chamber. This oil with some oil of the cylinder wall is burned by the high temperature combustion gases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc. Theengine oil is more consumed under severedriving conditions such as high speeds and
frequent acceleration and deceleration thannormal driving condition.
G040A03FC-GAT
CHANGING THE OIL AND FILTER (GASOLINE ENGINE)
The engine oil and filter should be changed at
those intervals specified in the maintenance schedule in Section 5. If the car is being drivenin severe conditions, more frequent oil and filterchanges are required.
The procedure for changing the oil and filter is
as follows: 1. Park the car on level ground and set the
parking brake. Start the engine and let itwarm up until the needle on the coolanttemperature gauge moves above the lowestmark. Turn the engine off and place the gearselector lever in "P" (automatic) or reversegear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.
3. Slide underneath the car and loosen the oil pan drain plug by turning it counterclock-wise with a wrench of the proper size. Besure that a drain pan is in position to catchthe oil as it drains out, then remove the drainplug.
WARNING:Be very careful when draining the engine oilas it may be hot enough to burn you!
4. When the oil has stopped draining, replace the drain plug using a new washer andretighten by turning it clockwise. Oil pan drain plug tightening torque: 1.6DOHC (European Community only: 4.0 ~4.5
kgf.m, Except European Comunity: 3.5 ~4.5 kgf.m) 1.8DOHC: 4.0 ~4.5 kgf.m
5. Remove the oil filter by turning it counter- clockwise with a oil filter wrench of the proper size. A certain amount of oil willcome out when you remove the filter. So besure to have your drain pan in place under-neath it.
