Checking the engine oil level and refilling engine oil
Fig. 274 Oil dipstick with markings.
r-111 First read and observe the Introductory L-W! information and safety warnings & on page 353.
Checklist
Carry out the steps in the specified order &:
1. With the engine at operating temperature, park the vehicle on a level surface to ensure that the engine oil reading is correct.
2. Switch off the engine and wait a few mi-nutes for the engine oil to flow back into the sump.
3. Open the bonnet&. 350.
4. Identify the engine oil filler cap and oil dip-stick. The engine oil filler opening bears the symbol 'l!:r. on the cap 275 and the oil dipstick has a coloured handle. If you can-not find the cap and dipstick please contact a qualified workshop.
5. Pull the dipstick out of the guide tube and wipe it off with a clean cloth.
6. Insert the oil dipstick into the guide tube again as far as it will go. If there is a mark-ing on the oil dipstick, this marking must fit in the corresponding groove at the top end of the guide tube when inserting.
7. Pull the dipstick out again and read the en-gine oil level on the dipstick 274 as follows:
@: do not refill oil Continue to step 15.
@: oil can be refilled (approximately 0.5 1). Continue to step 8 or 15.
©: oil must be refilled (approximately 1.0 1). Continue to step 8.
356 I Cleaning and maintenance
Fig. 275 in the engine compartment: engine oil filler cap (illustration).
8. After reading the oil level, push the oil dip-stick back into the guide tube as far as it will go.
9. Unscrew the engine oil filler opening cap =>Fig. 275.
1 0. Using only the engine oil approved by Volkswagen expressly for this engine, top up the oil in small gradual amounts (no more than 0.5 1).
11. To avoid overfilling, wait for approximately one minute after each pour to allow the en-gine oil to flow into the oil sump up to the marking on the engine oil dipstick.
12. Read the engine oil level from the dipstick again before refilling with a further small quantity of engine oil. Never overfill engine oil
13. After the refilling procedure, the engine oil level should be at least in the centre of area =>Fig. 274 @,but never above area®
14. After refilling, screw the engine oil filler cap back on correctly.
15. Re insert the oil dipstick correctly into the guide tube as far as it will go.
16. Close the bonnet correctly & 350.
A WARNING
Engine oil can Ignite if it comes into contact with hot engine components. lt can cause fires, burns and other serious Injuries.

Checking the coolant level and refilling coolant
Fig. 277 In the engine compartment: markings on the coolant expansion tank.
r--f'n First read and observe the Introductory information and safety warnings & on page 358.
The warning lamp for the engine coolant will light up if the engine coolant level is too low.
Preparation
• Park the vehicle on a firm and level surface.
• Allow the engine to cool down &.
• Open the bonnet&. 350.
• The coolant expansion tank has the all. symbol on its cap 278.
Checking the coolant level
• When the engine is cold, check the coolant lev-el on the side markings of the engine coolant ex-pansion tank 277.
• Refill the coolant if the liquid level is below the minimum marking ("min"). When the engine is warm, the coolant level may be slightly above the top end of the marked area.
Refilling coolant
• Always protect your face, hands and arms from hot coolant or steam by placing a suitable cloth on the cap of the coolant expansion tank.
• Unscrew the cap carefully &.
• Refill only new coolant according to the Volks-wagen specification 360)
• Only top up coolant if there is coolant residue in the expansion tank. If this is not observed, the en-gine could be damaged. If you cannot see any coolant in the expansion tank do not drive on. Seek professional assistance.
Fig. 278 In the engine compartment: coolant ex-pansion tank cap.
• If you can see coolant residue in the expansion tank, top up coolant until the level remains stable.
• The coolant level must be between the marks on the engine coolant expansion tank 277. Do not fill up over the top line of the marked area
• Close the cap tightly.
• If in an emergency you do not have access to the coolant of the required specification 360), do not use any other coolant addi-tive. Instead, initially refill with distilled water only. Then add the correct proportion of coolant ad-ditive as soon as possible 360.
A WARNING
Hot steam or engine coolant can cause seri-ous burns.
• Never open the bonnet if you can see or hear steam or engine coolant coming out of the engine compartment. Always wait until no escaping steam or coolant can be seen or heard.
• Always allow the engine to cool down completely before carefully opening the bon-net. Hot components can burn the skin.
• The following points should be noted be-fore opening the bonnet once it has cooled down.
