Practical hints What to do if ... Left display Right display Engine oil level Cannot measure engine oil level Engine oil level Check level Possible cause/consequence Vehicles with engine oil measuring system only: The measuring system is malfunctioning. Vehicles with oil dipstick only: The engine oil has dropped to a critical level. Possible solution Have the measuring system checked by an authorized Mercedes-Benz Center. N Check the engine oil level ( page 276) and add oil as required ( page 278). If you must add engine oil frequently, have the engine checked for possible leaks. When the message Add 1 qt engine oil at next refueling (Canada: 1 l) appears while the engine is running and at operating temperature, the engine oil level has dropped to approximately the minimum level. When this occurs, the warning will first come on intermittently and then stay on if the oil level drops further. If no oil leaks are noted, continue to drive to the nearest service station where the engine oil should be topped to the required level with an approved oil specified in the Factory Approved Service Products pamphlet. ! The engine oil level warnings should not be ignored. Extended driving with the symbol displayed could result in serious engine damage that is not covered by the Mercedes-Benz Limited Warranty. 376
