Problem
Possible causes/consequences and P Solutions
The coolant temperature
gauge shows av alue
above 248 ‡( 120 †).
The coolant warning
lamp may also be on and
aw arning tone may
sound. The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently. X
Stop as soon as possible and allow the engine and the coolant to
cool down. X
Check the coolant level ( Y
page 233). Observe the warning notes
as you do so and add coolant if necessary.
If the coolant level is correct ,t he engine radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled sufficiently. X
At coolant temperatures below 248 ‡( 120 †), drive to the nearest
qualified specialist workshop. X
Avoid heavy loads on the engine as you do so, e.g. driving in moun-
tainou st errai na nd stop-and-go traffic.
DYNAMIC SELEC Tb uttonUse the DYNAMIC SELECT button to change the
drive program. Depending on the drive program

G WARNING
If engine oil comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is ar isk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck. Let the engine cool dow na nd
thoroughly clea nt he engine oil off the com-
ponents before starting the engine.
H Environmental note
When adding oil ,t ake care not to spil la ny. If
oil enters the soil or waterways, it is harmfu lt o
the environment.
! Only use engine oil sa nd oil filters that have
been approved for vehicles with as ervice sys-
tem. You can obtai nal ist of the engine oils
and oil filters tested and approved in accord-
ance with the Mercedes-Benz Specifications
for Service Products at any Mercedes-Benz
Service center.
Damag etot he engine or exhaust system is
caused by the following: R
using engine oil sa nd oil filters that have not
been specifically approved for the service
system R
replacing engine oil and oil filters after the
interval for replacement specified by the
service system has been exceeded R
using engine oil additives.
! Do not add too much oil .Ift he oil leve li s
above the "max" mark on the dipstick, too
much oil has been added. This can lea dt o
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
Example :e ngine oil cap X
Turn cap C counter-clockwise and remove it. X
Add engine oil.
If the oil leve lisatorb elow the MIN mark on
the oil dipstick, add 1.1 US qt (1.0 liter) of
engine oil. X
Replace cap C on the filler neck and turn
clockwise.
Ensure that the cap locks into place securely. X
Check the oil leve la gain with the oil dipstick
( Y

ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible ,l et the engine cool dow na nd
touch only the components described in the
following.
G WARNING
The cooling system is pressurized, particularly
when the motor is warm .Ify ou open the cap,
you coul dbes calded if hot coolant sprays out.
There is ar isk of injury.
Let the engine cool dow nb efore you open the
cap. Wea rg love sa nd eye protection. Slowly
open the cap to relieve pressure.

( Y
page 284).
The coolant is am ixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following: R
Anti-corrosion protection R
Antifreeze protection R
Raising the boiling point
If the coolant has antifreeze protection dow nt o
-35 ‡( -37 †), the boiling point of the coolant
during operation is approximatel y2 66 ‡
(130 †).Service products and filling capacities 287
Technical data Z

The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should: R
be at least 50%. This will protec tt he engine
cooling system against freezin gd own to
approximately -35 ‡( -37 †).R
not exceed 55% (antifreez ep rotection 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 Servic eP roducts
310.1.
i When the vehicle is first delivered, it is filled
with ac oolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
i The coolant is checked with every mainte-
nanc ei nterval at aq ualified specialist work-
shop.

Important safety notes
G WARNING
Windshield washer concentrate could ignite if
it comes into contact with hot engine compo-
nent sort he exhaust system. There is ar isk of
fire and injury.
Make sure that no windshield washer con-
centrate 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 dam-
age the plastic lenses of the headlamps. ! Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
Do not use distilled or de-ionised water. Other-
wise, the level sensor may give af alse reading.
When handling washer fluid, observe the impor-
tant safety notes on service products
( Y
page 284).
At temperatures above freezing: X
Fill the washer fluid reservoir with am ixture of
water and windshield washer fluid, e.g. MB
SummerFit. X
Add 1p art MB SummerFit to 100 parts water.
At temperatures below freezing: X
Fill the washer fluid reservoir with am ixture of
water and washer fluid, e.g. MB WinterFit.
For the correc tm ixing ratio refer to the infor-
mation on the antifreeze reservoir.
i Add windshield washer fluid, e.g. MB Sum-
merFit or MB WinterFit, to the washer fluid all
year round.
Climate control system refrigerant
Important safety notes The climate control system of your vehicle is fil-
led with refrigerant R ‑ 134a.
The instruction label regarding the refrigerant
type used can be found on the radiator cross
member.
! Only the refrigerant R ‑ 134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant .O therwise, the climate
control system may be damaged.
Servic ew ork, such as refilling with refrigerant or
replacing component parts, may only be carried
out by aq ualified specialist workshop. All appli-
cable regulations, as well as SAE standard J639,
must be adhered to.
Always have work on the climate control system
carried out at aq ualified specialist workshop.288
