Engine oil level

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

1 Modern engines place great demands on their oil. It is very important that the correct oil for your car is used.
Engine oil grade MINI Long-life 04 SAE 0W-30 or SAE 5W-30 (fully synthetic) to ACEA A3 may be used for topping-up only (eg, Castrol Syntec)

Car care

The dipstick top is often brightly coloured for easy identification (see Underbonnet check points for exact location). Withdraw the dipstick.
Using a clean rag or paper towel remove 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 maximum mark (1) and lower minimum mark (2). 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. Unscrew the cap and top‑up the level; a funnel may help to reduce spillage. Add the oil slowly, checking the level on the dipstick often. Don’t overfill (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

The coolant level is indicated by the minimum and maximum marks on the side of the expansion tank at the rear of the engine compartment.
If topping-up is necessary, wait until the engine is cold. Slowly remove the overflow tank cap, to release any pressure present in the cooling system, and remove it.
Add a mixture of water and antifreeze to the overflow tank until the level of the coolant is just below the MAX mark on the overflow tank. Refit the cap securely. 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. 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.
HINT: The fluid level in the reservoir will drop slightly as the brake pads wear down, but the fluid level must never be allowed to drop below the MIN mark.

Before you start

The MAX and MIN marks are indicated on the side of 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 the reservoir cap and carefully lift it out of position, taking care not to damage the level switch float.Inspect the reservoir, if the fluid is dirty the hydraulic system should be drained and refilled.
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. After topping-up to the correct level, securely refit the cap and wipe off any spilt fluid.

Power steering fluid level

HINT: For the check to be accurate, the steering must not be turned while the level is being checked.

Safety first!

2 The need for frequent topping-up indicates a leak, which should be investigated immediately.
The reservoir is located near the rear of the engine compartment. Wipe clean the area around the reservoir filler neck and unscrew the filler cap/dipstick from the reservoir (engine stopped).
Insert the dipstick into the reservoir (without screwing on the cap), then remove it. The fluid level should be between MIN and MAX.
When topping-up, use Dexron II fluid and do not overfill the reservoir. When the level is correct, securely refit the cap.

Screen washer fluid level

3 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.
Caution: On no account use engine coolant antifreeze in the screen washer system – this may damage the paintwork.
The screen washer fluid reservoir is located on the right-hand side of the engine compartment, and the headlight washer reservoir is located on the left-hand side of the engine compartment.
If necessary, remove up the cap. When topping-up, add a screenwash additive in the quantities recommended by the manufacturer. It could also be time to replace the wiper blades. For details, click below

Wiper blade replacement

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. Wiper blades should be renewed annually.
To remove a front wiper blade, pull the arm away from the screen, turn the blade 90° to the arm, depress the clip and slide the blade down the arm.
To remove a rear wiper blade, pull the arm away from the screen, turn the blade 90° to the arm, and press the blade pivot pin out the recess in the arm.
