If these conditions are fulfilled, the front-passenger seat can be
occupied again. Whether the 45 indicator lamp remains lit
or goes out depends on how OCS classifies the occupant.
If the conditions are not fulfilled, the system is not operating

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. X
Park the vehicle on a level surface.
Only check the coolant level when the
vehicle

is on a level surface and the engine
has cooled down.
X Turn the SmartKey to position 2 in the
ignition lock ( Y page 139).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice

(Y page 139).
X Check the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡

(70 †).
X Turn the SmartKey to position
0 (Y page 139) in the ignition lock.
X Slowly turn cap : half a turn counter-
clockwise to allow excess pressure to
escape.
X Turn 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 level is approximately 0.6 in
(1.5 cm) above marker bar = in the fillerneck when warm, there is enough coolant
in coolant expansion tank
;.
X If necessary, add coolant that has been
tested and approved by Mercedes-Benz.
X Replace cap :
and turn it clockwise as far
as it will go.
For further information on coolant, see
(Y page 369).

WARNING
Washer solvent/antifreeze is highly
flammable. Do not spill washer solvent/
antifreeze

on hot engine parts, because it may
ignite and burn. You could be seriously
burned. X
To open: pull cap : upwards by the tab.
X Add the premixed washer fluid.
X To close:
press cap : onto the filler neck
until it engages.
The washer fluid reservoir is used for both the
windshield
washer system and the headlamp
cleaning system.

Maintenance and care Z

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,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
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 protect the 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.

Important safety notes G
WARNING
Washer solvent/antifreeze is highly
flammable. Do not spill washer solvent/
antifreeze

on hot engine parts, because it may
ignite and burn. You could be seriously
burned.
! 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
headlamps.
! Do not add distilled or de-ionized water to
the washer fluid container. Otherwise, the
level sensor may be damaged.
! Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
At temperatures above freezing:
X Fill the washer fluid reservoir with a mixture
of water and windshield washer fluid, e.g.
MB SummerFit.
Add 1 part MB SummerFit to 100 parts water. 370
