Engine oil level

1 • Make sure that the car is on level ground.
2 • Check the oil level before the car is driven, or at least 5 minutes after the engine has been switched off.
HINT: If the oil is checked immediately after driving the vehicle, some of the oil will remain in the upper engine components, resulting in an inaccurate reading on the dipstick.

The correct oil

3 Modern engines place great demands on their oil. It is very important that the correct oil for your car is used.
Engine oil grade:
  Models fitted with a particulate filter LongLife oil. VW 507 00 only
  Models without a particulate filter:
    Standard (distance/time) service interval Multigrade oil. VW 505 01 or better
    LongLife (variable) service interval LongLife oil. VW 506 01 or better*
* A maximum of 0.5 litres of standard VW oil may be used for topping-up when LongLife oil is unobtainable.

Car care

4 • If you have to add oil frequently, you should check whether you have any oil leaks. Place some clean paper under the car overnight, and check for stains in the morning. If there are no leaks, then the engine may be burning oil.
5 • Always maintain the level between the upper and lower dipstick marks (see photo 3). If the level is too low, severe engine damage may occur. Oil seal failure may result if the engine is overfilled by adding too much oil.
The dipstick is located on the front of the engine (see Underbonnet check points for exact location). Withdraw the dipstick.
Using a clean rag or paper towel, wipe all oil from the dipstick. Insert the clean dipstick into the tube as far as it will go, then withdraw it again.
Note the oil level on the end of the dipstick, which should be between the upper and lower mark. Approximately 1.0 litre of oil will raise the level from the lower mark to the upper mark.
Oil is added through the filler cap on top of the engine. Turn the cap through a quarter-turn anti-clockwise and withdraw it. Top-up the level. A funnel may help to reduce spillage. Add the oil slowly, checking the level on the dipstick often. Do not overfill. Should you need to renew the oil and filter, click below

Coolant level

Warning: Do not attempt to remove the expansion tank pressure cap when the engine is hot, as there is a very great risk of scalding. Do not leave open containers of coolant about, as it is poisonous.

Car care

6 • With a sealed-type cooling system, adding coolant should not be necessary on a regular basis. If frequent topping-up is required, it is likely there is a leak. Check the radiator, all hoses and joint faces for signs of staining or wetness, and rectify as necessary.
7 • It is important that antifreeze is used in the cooling system all year round, not just during the winter months. Don’t top up with water alone, as the antifreeze will become diluted.
The coolant level varies with the temperature of the engine. When the engine is cold, the coolant level should be between the MIN and MAX marks.
If topping-up is necessary, wait until the engine is cold. Slowly unscrew the cap to release any pressure present in the cooling system, and remove the cap.
Add a mixture of water and antifreeze to the expansion tank until the coolant level is on the MAX mark. Should you need to replace the coolant, click below

Brake (and clutch) fluid level

Warning: Brake fluid can harm your eyes and damage painted surfaces, so use extreme caution when handling and pouring it.
Warning: Do not use fluid that has been standing open for some time, as it absorbs moisture from the air, which can cause a dangerous loss of braking effectiveness.

Safety first!

8 • If the reservoir requires repeated topping-up this is an indication of a fluid leak somewhere in the system, which should be investigated immediately.
9 • If a leak is suspected, the car should not be driven until the braking system has been checked. Never take any risks where brakes are concerned
The MIN mark is indicated on the reservoir. The fluid level must be kept above this mark at all times.
If topping-up is necessary, first wipe clean the area around the filler cap to prevent dirt entering the hydraulic system. Unscrew the reservoir cap. Carefully add fluid, taking care not to spill it onto the surrounding components. Use only DOT 4 fluid; mixing different types can cause damage to the system.
On completion, securely refit the cap and wipe away any spilt fluid. With the ignition switched on, check the operation of the brake fluid low level warning lamp by having an assistant depress the button on the top of the reservoir cap.

Washer fluid level

10 • Screenwash additives not only keep the windscreen clean during bad weather, they also prevent the washer system freezing in cold weather – which is when you are likely to need it most. Don’t top-up using plain water, as the screenwash will become diluted, and will freeze in cold weather.
Warning: On no account use engine coolant antifreeze in the screen washer system – this may damage the paintwork.
The reservoir for the windscreen and headlight washer systems is on the right-hand side of the engine compartment.
A screenwash additive should be added in the quantities recommended on the bottle. It could also be time to replace the wiper blades. For details, click below
