One of the following messages will subsequently appear on the indicator: "ENGINE OIL LEVEL - O.K." No oil needs to be added. "ENGINE OIL LEVEL - ADD 1.0 QUART" (Canada: 1.0 L) "ENGINE OIL LEVEL - ADD 1.5 QUART" (Canada: 1.5 L) "ENGINE OIL LEVEL - ADD 2.0 QUART" (Canada: 2.0 L) See page 253 for instructions on adding engine oil. "ENGINE OIL LEVEL - REDUCE OIL LEVEL" Do not overfill the engine. Excessive oil must be siphoned or drained off. It could cause damage to the engine and catalytic converter not covered by the Mercedes-Benz Limited Warranty. The message "MEASURING NOT POSSIBLE" will be displayed if a proper oil level check cannot be performed. The engine oil level check can be repeated after a short time. Perform the engine oil level check with the dipstick, if it cannot be completed via the multifunction display. See page 253. In this case we recommend that you have the system checked at a Mercedes-Benz Center. Note: See malfunction and warning messages on page 232 and page 242 if an engine oil level indicator appears on the multifunction display when the engine is running. The engine oil level cannot be checked while the engine is running. The "ENGINE OIL LEVEL - NOT WHEN ENGINE ON" message will appear. Engine oil consumption Engine oil consumption checks should only be made after the break-in period. During the break-in period, higher oil consumption may be noticed and is normal. Frequent driving at high engine speeds results in increased consumption.
