the on-board voltage is too low, the power
to the sockets is automatically cut. This
ensures that there is sufficient power to
start the engine.

Important safety notes G
WARNING
When you operate or program the garage door
with the integrated garage door opener,
persons in the range of movement of the
garage door can become trapped or struck by
the garage door. There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
The HomeLink ®
garage door opener
integrated in the rear-view mirror allows you
to operate up to three different door and gate
systems.
Use the integrated garage door opener only
on garage doors that:
R have safety stop and reverse features and
R meet current U.S. federal safety standards
When programming a garage door opener,
park the vehicle outside the garage.
i Certain garage door drives are
incompatible with the integrated garage
door opener. If you have difficulty
programming the integrated garage door opener, contact an authorized Mercedes-
Benz Center.

Notes on the oil level Depending on the driving style, the vehicle
consumes up to 0.9 US qt
(0.8l) of oil over a
distance of 600 miles (1000km). The oil
consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
AMG vehicles: before operation on race
tracks, check the oil level and (Y page 275)
add oil if necessary (Y page 276). Race track
operation is only permitted with a maximum
engine oil level.
Depending on the engine, the oil dipstick may
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
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement.
