Engine oil

Notes on the oil level

Depending on the driving style, the vehicle consumes up to 0.9 US qt (0.8 l) of oil over a distance of 600 miles (1000 km). The oil consumption may be higher than this when the vehicle is new or if you frequently drive at high engine speeds.

Checking the oil level using the oil dipstick

Example: oil dipstick

When checking the oil level: • park the vehicle on a level surface.

• the engine should be switched off for approximately five minutes if the engine is at normal operating temperature.

• the engine should be switched off for at least 30 minutes if the engine is not at operating temperature (i.e. if you only start the engine briefly).

► Pull oil dipstick 1 out of the dipstick guide tube.

► Wipe off oil dipstick 1.

► Slowly slide oil dipstick 1 into the guide tube to the stop, and take it out again. The oil level is correct if the level is between MIN mark 3 and MAX mark 2.

► Add oil if necessary.

Checking the oil level using the onboard computer

Do not add too much oil. adding too much engine oil can result in damage to the engine or to the catalytic converter. Have excess engine oil siphoned off.

G 65 AMG: the oil level can be checked using the on-board computer only.

On all other models, the oil dipstick must be used to check the engine oil level.

When checking the oil level: • park the vehicle on a level surface.

• the engine should be switched off for approximately five minutes if the engine is at normal operating temperature.

► Make sure that the SmartKey is in position 2 in the ignition lock.

► Press the or
button on the
steering wheel to select the following message:

The measurement takes a few seconds. You will see one of the following messages in the multifunction display:
• Engine Oil Level OK • Add 1.0 qt (Canada: 1.0 liter) to reach maximum oil level.

• Add 1.5 qts (Canada: 1.5 liters) to reach maximum oil level.

• Add 2.0 qts. (Canada: 2.0 liters) to reach maximum oil level.

► Add oil if necessary.

If the engine is at normal operating temperature and the Engine Oil Reduce Oil Level message appears, the engine oil level is too high.

► Have excess oil siphoned off.

If the Switch ignition on to check engine oil level message appears: X Turn the SmartKey to position 2 in the ignition lock .

If the Observe Waiting Time message appears: X If the engine is at normal operating temperature: repeat the measurement after about five minutes.

► If the engine is not at normal operating temperature: (e.g. if the engine was only started briefly) repeat the measurement after about 30 minutes.

If the Engine Oil level Not With Engine On message appears: X Switch off the engine.

► If the engine is at normal operating temperature: wait about five minutes before carrying out the measurement.

► If the engine is not at normal operating temperature: e.g. if the engine was only started briefly, wait approximately 30 minutes before carrying out the measurement.

If you wish to cancel the measurement, press the * or & button on the multifunction steering wheel.

Adding engine oil

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

Only use engine oils and oil filters that have been approved for vehicles with a service system. You can obtain a list of the engine oils and oil filters tested and approved in accordance with the Mercedes-Benz Specifications for Service Products at any Mercedes-Benz Service center.

Damage to the engine or exhaust system is caused by the following: • using engine oils and oil filters that have not been specifically approved for the service system
• replacing engine oil and oil filters after the interval for replacement specified by the service system has been exceeded R using engine oil additives.

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.

Example: engine oil cap

► Turn cap 1 counter-clockwise and remove it.

► Add the amount of oil required.

Observe the specifications in the on-board computer when doing so or fill carefully to the maximum mark on the oil dipstick.

Further information on engine oil .

The difference between the minimum mark and the maximum mark on the oil dipstick is approximately 2.1 US qt (2 l).

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

Ensure that the cap locks into place securely.
