Engine compartment: Engine oil filler cap

– Unscrew cap e from oil filler opening ⇒ fig. 256.
– Carefully put in the specified grade of oil 0.5 litres at a time.
– Check the oil level again after two minutes by calling up the sound system or MMI* display or using the oil dipstick.
– If the oil level is too low, add more engine oil.
– Replace the oil filler cap carefully and push the dipstick all the way in (on vehicles with dipstick).

WARNING

• • Ensure that no oil comes into contact with hot engine components when topping up: this could cause a fire.
• • Wash your skin thoroughly if it comes into contact with engine oil.

Caution

• • The oil level must never be above area a, fig. 254, as this may result in damage to the catalytic converter or to the engine. On vehicles without an oil dipstick, you can check the oil level via the sound system or MMI*. Contact a qualified workshop to extract the engine oil if necessary.
• • No additives should be used with engine oil. Any damage caused by the use of such additives would not be covered by the factory warranty.

For the sake of the environment

• • Never pour oil down drains or into the ground.
• • Always observe statutory requirements when disposing of empty oil canisters.
