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 (petrol engines)
  Standard (distance/time) service interval Multigrade engine oil, viscosity SAE 5W/40 to 20W/50 VW engine oil VW 501 01, 502 00, 504 00 or better
  LongLife (variable) service interval VW LongLife engine oil VW 503 00, 504 00 or better
Engine oil grade (diesel engines)
  Standard (distance/time) service interval: Multigrade engine oil, viscosity SAE 5W/40 to 20W/50
    Engines without particulate filter VW 505 01 or better
    Engines with particulate filter VW 507 00 or better
  LongLife (variable) service interval: VW LongLife engine oil
    Engines without particulate filter VW 506 01, 507 00 or better
Engines with particulate filter VW 507 00 or better

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. 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 often brightly coloured for easy identification (see Underbonnet check points for exact location). Withdraw the dipstick, then use a clean rag or paper towel to wipe the oil from it. Insert the clean dipstick into the tube as far as it will go, then withdraw it again.
Note the level on the end of the dipstick, which should be between the upper (MAX) and lower (MIN) mark.
Oil is added through the filler cap aperture. Unscrew the cap.
Place some cloth rags around the filler cap aperture, then top-up the level. A funnel may help to reduce spillage. Add the oil slowly, checking the level on the dipstick frequently. Avoid overfilling (see Car care). 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 the specified antifreeze to the expansion tank until the coolant level is halfway between the level marks. Refit the cap and tighten it securely. Should you need to replace the coolant, click below

Brake (and clutch) fluid level

Note: On manual transmission models, the fluid reservoir also supplies the clutch master cylinder with fluid

Before you start

8 • Make sure that the car is on level ground.
9 • Cleanliness is of great importance when dealing with the braking system, so take care to clean around the reservoir cap before topping-up. Use only clean brake fluid.

Safety first!

10 • If the reservoir requires repeated topping-up, this is an indication of a fluid leak somewhere in the system, which should be investigated immediately. Note that the level will drop naturally as the brake pad linings wear, but must never be allowed to fall below the MIN mark.
11 • 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.
Warning: Brake fluid can harm your eyes and damage painted surfaces, so use extreme caution when handling and pouring it. Do not use fluid which has been standing open for some time, as it absorbs moisture from the air, which can cause a dangerous loss of braking effectiveness.
The MIN and MAX marks are indicated on the reservoir. The fluid level must be kept between the marks 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 and remove the reservoir cap.
Carefully add fluid, taking care not to spill it onto the surrounding components (use a funnel). 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.

Washer fluid level

12 • 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 screenwash fluid reservoir is located on the right-hand side of the engine compartment, behind the headlight. Pull up the filler cap to release it from the reservoir.
When topping-up the reservoir, 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

Wiper blade replacement

Note: It is possible to park the wipers in a Service/Winter position with both wipers pointing upwards to allow unrestricted removal of the blades. To do this, operate the wipers within 10 seconds of switching off the ignition. The wiper arms can now be lifted away from the windscreen.
Check the condition of the wiper blades; if they are cracked or show any signs of deterioration, or if the glass swept area is smeared, renew them. For maximum clarity of vision, wiper blades should be renewed annually, as a matter of course.
To remove a windscreen wiper blade, pull the arm fully away from the screen until it locks. On standard wipers, swivel the blade through 90º, press the locking tab with your fingers, and slide the blade out of the hooked end of the arm.
On aerodynamic wipers, depress the catch with a screwdriver, and pull the blade from the arm.
Where applicable, don’t forget to check the tailgate wiper blade as well. To remove the blade, depress the retaining tab and slide the blade out of the hooked end of the arm.
