settings
R optimal fuel consumption resulting from
the transmission shifting up sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
R increased sensitivity; this improves driving
stability on slippery road surfaces, for
example
R the transmission shifting up sooner; this
results in the vehicle being driven at lower
engine speeds and the wheels being less
likely to spin

by the following:
R sporty engine and transmission settings

Adding engine oilHEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
! Use only engine oils and oil filters that
have been approved for vehicles equipped
with a service system. A list of the engine
oils and oil filters tested and approved in
accordance with the Mercedes-Benz
Specifications for Service Products can be
called up by visiting http://
www.mbusa.com (USA only). More
information about tested and approved
engine oils and oil filters is available from
any authorized Mercedes-Benz Center.
Damage to the engine or exhaust system is
caused by the following:
R using engine oils and oil filters which
have not been specifically approved for
the service system.
R replacing the engine oil or oil filter after
the replacement interval required by the
service system has elapsed
R using engine oil additives.
XUnscrew and remove oil filler cap : with
the integrated dipstick.XAdd the amount of oil required.
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic
converter. Have excess oil siphoned off.
XReplace cap : on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
You will find further information about engine
oil in the "Technical data" section
( Y page 282).

Checking the coolant level
GWARNING
In order to avoid any potentially serious burns:
R use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
R do not remove the pressure cap on the
coolant reservoir if the coolant temperature
is above 158 ‡ (70 †). Allow the engine to
cool down before removing the cap. The
coolant reservoir contains hot fluid and is
under pressure.
R using a rag, slowly turn the cap
approximately 1
/ 2 turn to relieve excess
pressure. If opened immediately, scalding
hot fluid and steam will be blown out under
pressure.
R do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts.
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XSet the Start/Stop button to key position
2 .XCheck the coolant temperature display in
the "AMG" menu ( Y page 160).
The coolant temperature must be below
158 ‡ (70 †).220Engine compartmentMaintenance and care
