Practical hints What to do if ... Left display Right display USA only: Add 1 qt engine oil at next refueling. Possible cause/consequence Vehicles with engine oil measuring system only: The engine oil level is too low. Possible solution Add engine oil ( page 286) and check the engine oil level ( page 284). N Canada only: Add 1 liter engine oil at next refueling. When the message Add 1 qt engine oil at next refueling (Canada: 1 liter) 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 is at first intermittent and then remains on if the oil level drops further. Visually check for oil leaks. If there are no obvious oil leaks, drive to the nearest service station to refill the engine oil should be topped to the required level. For information on approved engine oils, refer to the Factory Approved Service Products pamphlet (USA only) or contact an authorized Mercedes-Benz Center. ! 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. 387
