Checking the oil level using the on-
board computer
On vehicles with a 12-cylinder engine, the oil
level can be checked using the on-board
computer. On all other models, the dipstick
must be used to check the engine oil level.
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.
XMake sure that the SmartKey is in
position 2 in the ignition lock.XPress the ; or = button to select the
Service menu.XPress the : or 9 button to select
Engine Oil Level .XPress a.
The Measuring Engine Oil Level
Accurate Only When Vehicle is
Level message appears in the
multifunction display.
The measurement takes a few seconds. You
will see one of the following messages in the
multifunction display:
R Engine Oil Level OK
R Add1.0 l Engine OilAt Next
Refueling
R Add1.5 l Engine OilAt Next
Refueling
R Add2.0 l Engine OilAt Next
Refueling
XAdd oil if necessary.
If the engine is at normal operating
temperature and the ReduceEngine Oil
Level message appears, the engine oil level
is too high.
XHave excess oil siphoned off.
! Do not add too much oil. Adding too much
oil can result in damage to the engine or the
catalytic converter. Have excess oil
siphoned off.
If the For Engine Oil Level Ignition
Must be On message appears:XTurn the SmartKey to position 2 in the
ignition lock.
If the Need More Time to Check Engine
Oil Level message appears:
XIf the engine is at normal operating
temperature: repeat the measurement
after about five minutes.
If the engine is not at normal operating
temperature (e.g. if the engine was only
started briefly): repeat the measurement
after about 30 minutes.
If the Engine Oil Level Not Measurable
With Running Engine message appears:
XSwitch off the engine.XIf the engine is at normal operating
temperature: wait about five minutes
before carrying out the measurement.
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.
i If you wish to cancel the measurement,
press the % button on the multifunction
steering wheel.
Adding engine oil
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
! Only use engine oils and oil filters which
have been approved for vehicles with a
service system. A list of the engine oils and
oil filters that have been tested and
approved according to the Mercedes-Benz
specifications for service products can be
found on the Internet at http://
www.mbusa.com (USA only). Further
information on tested and approved engine
oils and oil filters can be obtained from any
authorized Mercedes-Benz Center.
406Engine compartmentMaintenance and care

The following causes engine failure or
damage to the exhaust system:
Rusing engine oils and oil filters that are
not specifically approved for the service
system
Rreplacing the engine oil and oil filter after
having exceeded the interval for
replacement prescribed by the
maintenance system
Rusing engine oil additives
Engine oil cap (example)
Engine oil cap (AMG vehicles, example: 8-cylinderengine)
XTurn cap : counter-clockwise and remove
it.
XAdd the amount of oil required.
Observe the specifications in the on-board
computer when doing so or fill carefully to the
maximum mark on the oil dipstick.
iVehicles with a dipstick: the difference in
quantity between the MIN mark and the
MAX mark on the dipstick is (depending on
the engine) approximately 1.6 to
2.1 US qt (1.5 to 2 l).
iAMG vehicles with 8-cylinder engines: the
difference in quantity between the MIN
mark and the MAX mark on the dipstick is
approximately 1.6 US qt (1.5 l).
! 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.
Further information on engine oil
(Y page 471).
XReplace cap : on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
Checking and adding other service
products
Check coolant level
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XTurn the key to position 2 (Y page 267) in
the ignition lock.
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 267).
XCheck the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
GWarning
In order to avoid any potentially serious burns:
Ruse 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.
Rdo 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
