Environmental note
When adding oil, take care not to spill any. If oil enters the soil or waterways, it is harmful to the environment.

WARNING  
If engine oil comes into contact with hot engine parts, it may ignite and you could burn yourself. Do not spill any engine oil on hot engine parts.

Use only engine oils and oil filters that have been approved for vehicles equipped with a service system. A list of the engine oils and oil filters tested and approved in accordance with the Mercedes-Benz Specifications for Service Products can be called up by visiting http:// www.mbusa.com (USA only). More information about tested and approved engine oils and oil filters is available from any authorized Mercedes-Benz Center.

Damage to the engine or exhaust system is caused by the following:

• using engine oils and oil filters which have not been specifically approved for the service system.
• replacing the engine oil or oil filter after the replacement interval required by the service system has elapsed
• using engine oil additives.

Example: engine oil cap

► Turn cap 1 counter-clockwise and remove it.
► Add the amount of oil required.

Fill carefully to the maximum mark on the oil dipstick.

Depending on the engine, the difference in quantity between the MIN mark and the MAX mark on the dipstick is approximately 1.6 to 2.1 US qt (1.5 to 2 l).

Do not add too much oil. If the oil level is above the "max" mark on the dipstick, too much oil has been added. This can lead to damage to the engine or the catalytic converter. Have excess oil siphoned off.

For further information on engine oil, see.

► Replace cap 1 on the filler neck and tighten clockwise.

Ensure that the cap locks into place securely.
