Check Coolant
Level See
Operator's Manual The coolant level is too low.
!
Avoid making long journeys with too little coolant in the engine
cooling system. The engine will otherwise be damaged.
X Add coolant, observing the warning notes before doing so
(Y page 276).
X If coolant needs to be added more often than usual, have the
engine coolant system checked at a qualified specialist
workshop. 000A The fan motor is faulty.
X
At coolant temperatures below 248 ‡ (120 †) drive to the
neares tqualified specialist workshop.
X Avoid subjecting the engin eto heavy loads, e.g. driving in
mountainous terrain, and stop-and-go traffic. 000A

G WARNING
Do no tdrive when youre ngine is overheated. Thi scan cause some
fluids which may have leaked into the engine compartmen tto

Stea mfrom the overheated engine can also cause serious burns
which can occur just by opening the hood.
There is a risk of injury.
X Pull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
X Secure the vehicle against rolling away (Y page 150).
X Waitu ntil the engine has cooled down.
X Make sure tha tthe air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice.
X Do not start the engine again until the display message goes out
and the coolant temperature is below 248 ‡ (120 †).
Otherwise, the engine could be damaged.
X Pay attention to the coolant temperature display.
X If the temperature increases again, visit a qualified specialist
workshop immediately.
Under normal operating conditions and with the specified coolant
level, the coolant temperature may rise to 248 ‡ (120 †). 220

Problems with the 115
Vpower socket Problem Possible causes/consequences and
0001 Solutions
The warning lamp on
the 11
5Vpower socket
is not lit. The on-board voltage is too low because the battery is too weak.
X
Start the engine.
or
X Charge the battery (Y page 290).
If the indicator lamp still does not light up:
X Visit a qualified specialist workshop. The temperature of the DC/AC converter is temporarily too high.
X Remove the electronic device connector from the 115 V socket.
X Let the DC/AC converter cool down.
If the indicator lamp still does not light up after cooling down the
converter:
X Visit a qualified specialist workshop. You have connected a small electronic device that has a constant
nominal power of less than 150 W, but a very high switch-on
current. This device will not work. If you connect such a device,
the 115
Vpower socket will not supply it with power.
X Connect a suitable device. mbrace

Example: engine oil cap
X Turn cap 0002counter-clockwise and remove
it.
X Add engine oil.
If the oil level is at or below the MIN mark
on the oil dipstick, add 1.1 US qt (1.0 liter)
of engine oil.
X Replace cap 0002on the filler neck and turn
clockwise.
Ensure that the cap locks into place
securely.
X Check the oil level agai nwith the oil
dipstick (Y page 275).
Further information on engine oil
(Y page 340). Checking and adding other service
products
Checking coolant level G
WARNING
The engine cooling system is pressurized,
particularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolan tspraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
Only chec kthe coolant level when the vehicle
is on a level surface and the engine has cooled
down. X
Turn the SmartKey to position 2in the
ignition lock (Y page 133).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 133).
X Check the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡ (70 †). X
Slowly turn cap 0002half a turn counter-
clockwise and allow excess pressure to
escape.
X Turn cap 0002further counter-clockwise and
remove it.
If the coolant is at the level of marker bar
0022 in the filler neck when cold, there is
enough coolant in coolant expansion
tank 0003.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar 0022in the fuel
filler neck when warm, there is enough
coolant in expansion tank 0003.
X If necessary, add coolant that has been
tested and approved by Mercedes-Benz.
X Replace cap 0002and turn it clockwise as far
as it will go.
For further information on coolant, see
(Y page 341). 276
Engine compartmentMaintenance and care

Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB Specifications for
Service Products 310.1, e.g. on the
Internet at
http://bevo.mercedes-benz.com. Or
contact a qualified specialist workshop.
! Always use a suitable coolant mixture,
eve ninc ountries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
When handling coolant, observe the
important safety notes on service products
(Y page 337).
The coolant is a mixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
R corrosion protection
R antifreeze protection
R raising the boiling point
If the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the
coolant during operation is approximately
266 ‡ (130 †).
The antifreeze/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. This will protec tthe engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in
accordance with MB Specifications for
Service Products 310.1. The coolant is checked with every
maintenance interval at a qualified specialist
workshop.
i When the vehicle is first delivered, it is
filled with a coolant mixture that ensures
adequate antifreeze and corrosion
protection.

WARNING
Windshield washer concentrate is highly
flammable. If it comes into contact with hot
engine components or the exhaust syste mit
could ignite. There is a ris koffire and injury.
Make sure that no windshield washer
concentrate is spilled next to the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lenses of the
