over
adistanc eof600 miles (1,000 km). The
oil consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
Depending on the engine, the oil dipstic kmay
be in a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for

starting connection point.
The jump-starting connection point is in the
engine compartment (Y page 283).
X Open the hood (Y page 260).
X Connect the battery charger to the positive
terminal and ground point in the same
order as when connecting the donor
battery in the jump-starting procedure

warning lamps in the instrument cluster do
not light up, it is highly likely that the
discharged battery has frozen. In this case,
you may neither charge the battery nor jump-
start the vehicle. The service life of a thawed-
out battery may be shorter. The starting
characteristics can be impaired, particularly
at low temperatures. Have the thawed-out
battery checked at a qualified specialist
workshop.

battery charger which has been tested and
approved by Mercedes-Benz.Ab attery
