temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement.
iIf 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.
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.

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 299) in
the ignition lock.
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 299).
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
coolant reservoir contains hot fluid and is
under pressure.
Rusing 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.
Rdo not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts.
XSlowly turn cap : half a turn counter-
clockwise and allow excess pressure to
escape.
XTurn cap : further counter-clockwise and
remove it.
If the coolant is at the level of marker bar
= in the filler neck when cold, there is
enough coolant in coolant expansion
tank ;.
If the coolant is approximately 0.6 in
(1.5 cm) above marker bar = in the filler
neck when warm, there is enough coolant
in coolant expansion tank ;.
XIf necessary, add coolant that has been
tested and approved by Mercedes-Benz.
XReplace cap : and turn it clockwise as far
as it will go.
For further information on coolant, see
(Y page 515).

windshield washer system and the headlamp

Coolant
Important safety notes
The coolant is a mixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
The cooling system is filled with coolant at the
factory which contains antifreeze/corrosion
inhibitor that ensures protection down to
approximately -35 ‡ (-37 †).
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants and on
filling can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com . You
can also consult an authorized Mercedes-
Benz Center.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the
coolant in the pressurized system is
approximately 266 ‡ (130 †).
Your vehicle has a range of aluminum
components. Use of aluminum components
in the engine make it necessary to specifically
match the antifreeze/corrosion inhibitor in
these systems in order to protect the
aluminum parts. Using other antifreeze/
corrosion inhibitors without these
characteristics affects the service life.
The coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and provide protection from
overheating. In the Service Booklet, you can
find information on the intervals for renewal.
The renewal interval is determined by the
coolant type and the cooling system design.
The renewal interval in the Service Booklet is
only valid if the coolant is added or renewed
with Mercedes-Benz approved products.
Therefore, only use MB 326.0 antifreeze/
corrosion inhibitor or another Mercedes-Benz
approved product of the same specification.
Information on other Mercedes-Benz
approved products of the same specification
can be obtained at any authorized Mercedes-
Benz Center or on the Internet at
http://bevo.mercedes-benz.com .
The coolant is checked at every service date
at an authorized Mercedes-Benz Center.
The antifreeze/corrosion inhibitor
concentration in the cooling system should:
R be at least 50%. This will protect the cooling
system against freezing down to around
-35 ‡ (-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ (-45 †); otherwise, heat will
not be dissipated as effectively.
If the coolant level is too low, MB 326.0
antifreeze/corrosion inhibitor should be
added. Have the cooling system checked for
leaks.
