VEHICLE MAINTENANCE REQUIREMENTS
5- 6 6ZF060D2-A
o Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and connec- tions for leakage and damage. Replace anydamaged or leaking parts immediately.
WARNING (Diesel only): Never work on injection system with en-gine running or within 30 seconds aftershutting 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 ittouch 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. 6ZF060E1-A
o Timing belt Replace timimg belt and inspect all associated parts related for damage and deformation.Replace any damaged parts immediately. 6ZF060G1-A
o Vapour hose and fuel filler cap The vapour hose and fuel filler cap should be inspected at those intervals specified in themaintenance schedule. Make sure that a newvapour hose or fuel filler cap is correctlyreplaced. 6ZF060F1-A
o Vacuum, crankcase
ventilation hoses
Inspect the surface of hoses for evidence of heat and/or mechanical damage. Hard andbrittle rubber, cracking, tears, cuts, abra-sions, and excessive swelling indicate dete-rioration. Particular attention should be paid toexamining those hose surfaces nearest tohigh heat sources, such as the exhaustmanifold.Inspect the hose routing to assure that thehoses do not come in contact with any heatsource, sharp edges or moving componentwhich might cause heat damage or mechani-cal wear. Inspect all hose connections, suchas clamps and couplings, to make sure theyare secure, and that no leaks are present.Hoses should be replaced immediately if thereis any evidence of deterioration or damage.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
6ZF060M1-A
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 severeconditions, more frequent oil and filter changesare required.
6ZF060B1-A
o Drive belts Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation andreplace if necessary. Drive belts should bechecked periodically for proper tension andadjusted as necessary.
6ZF060C1-A
o Fuel filter A clogged filter can limit the speed at which the
vehicle may be driven, damage the emissionsystem and cause hard starting. If an exces-sive amount of foreign matter accumulates inthe fuel tank, the filter may require replace-ment more frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at theconnections.

DAILY OPERATING CHECKS
The following items should be checked on a
daily basis or whenever the vehicle is refuelled, whichever occurs sooner.
o Engine oil level.
o Engine coolant level.
o Power steering fluid level.
o Brake fluid level.
o Windscreen washer fluid level.
o Battery condition.
o Tyre condition and pressures.
o Operation and cleanliness of all lighting equipment.
o Windscreen wiper and washer operation.
o Horn operation.
o Warning light operation.
o Adjustment and cleanliness of mirrors.
o Seat and seat belt adjustment and opera- tion.
o Fluid leakage.
The vehicle must not be driven if the daily
operating checks indicate that any item of equip- ment related to the safety or roadworthiness ofthe vehicle is not functioning correctly. G030A01FC-EAT
ENGINE OIL
The correct engine oil level is of paramount
importance. An excessively high or low oil levelmay result in irreparable damage being sus-tained by the engine. The engine oil levelmust be checked on a daily basis, wheneverthe vehicle is refuelled or before starting along trip, whichever occurs sooner.
In addition, it is imperative that only an ap-
proved grade and specification of oil is used toavoid the possibility of serious engine damageand premature wear. The use of "budget price"oil is a false economy that must be avoided ifthe maximum reliability and useful life is to beobtained from the vehicle.

A multi grade oil having a specification which meets A.P.I. specification of SG or above isrecommended. The oil viscosity should be se-lected according to the operating environmentof the engine by means of the table shown inthe illustration. The engine oil recommenda-tions are complete in themselves and the use ofadditives is neither required nor recommended.The use of engine oil additives may result ininvalidation of the vehicle warranty. NOTE: The use of a 5W-20 multi grade oil is not recommended for sustained high speed use.

The engine oil quality should meet the follow-
ing classification:
API class: CF-4 or ABOVEACEA class: B4 or ABOVE

SG030C1-E
Engine Oil Level NOTE: SAE 0W-30 oil is for extra cold zone and
to be restricted by driving condition and dealing area. (Especially, not recommend-ed for sustained high loaded and highspeed operation.) The engine oil level should be checked with
the engine at normal operating temperatureand the vehicle parked upon level ground.
Prior to checking the level, the vehicle should
be allowed to stand for several minutes after theengine has been switched off to allow the oil todrain back to the sump.
Withdraw the dipstick and wipe it with a clean
rag. Replace the dipstick fully and withdrawagain when the oil level may be read from thestick. Normal oil level is indicated when the oilis present between the two marks on thestick. It is not necessary to add oil if the levelis above the lower mark and in any case, oilmust not be added to the degree that the levelexceeds the upper mark. Replace the dip-stick fully after checking the level. SG030D2-E
ENGINE OIL REPLENISHMENT
If the indicated oil level is at or below the lower
mark of the dipstick, oil should be added untilthe level is at or below the upper mark.
To add oil to the engine, remove the filler cap by
rotating in an counterclockwise direction andpour engine oil into the engine. Before checking
