How to Check the Engine Oil Level on Mercedes-Benz E-Class and CLK-Class Models

Some Mercedes-Benz E-Class and CLK-Class models do not have a user-accessible engine oil dipstick. To check the oil level, you must access the menu in the instrument cluster. The procedures are slightly different for each model, but you can measure your Mercedes-Benz engine oil level.

Procedure:

1. Make sure the car is parked on a level surface.
2. Bring the engine to normal operating temperature, switch it off, and wait at least five minutes. On some W211 models, wait 30 minutes if the engine is cold.
3. Turn the key to position 2 so the ignition is on, but do not start the engine.
4. Use the multifunction steering wheel buttons to return to the standard odometer or speed display.
5. Press the group buttons to check the oil level.
6. The button sequence varies by model year. Follow the steps below and check your owner’s manual if your instrument cluster menu is different. Get a FREE copy of your owner’s manual.
7. If the display shows ENGINE OIL LEVEL OK, no oil is needed. If it requests a specific quantity, add only that amount and check the level again. If it shows REDUCE OIL LEVEL, remove the excess oil. Overfilling can damage the engine and catalytic converter
