When the message “Check engine oil level
at next refueling” (S 550) or “Add 1.0 qts.
(Canada:1.0 l) engine oil at next refueling”
(S 600 and S 65 AMG) appears while the
engine is running and at operating temper-
ature, 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.
Visually check for oil leaks. If no obvious 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 Facto-
ry Approved Service Products pamphlet.For information on approved engine oils,
refer to the Factory Approved Service
Products pamphlet (USA only) or contact
