WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department. G
WARNING
Certain components in the engine compart-
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, let the engine cool down
and touch only the components described in
the following. G
WARNING
Windshield washer concentrate is highly
flammable. If windshield washer concentrate
gets onto hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure that windshield washer concen-
trate is not spilled in the vicinity of the filler
neck.
! Only use washer fluid which is suitable for
lamp lenses, e.g. MB SummerFit or MB Win-
terFit. Unsuitable washer fluid may damage
the lamp lenses of the headlamps. Example: washer fluid reservoir

mation regarding washer fluid under "Service

WARNING

When handling washer fluid, observe the
important safety notes on service products
(Y page
305).
Mixing ratio Add windshield washer concentrate to the
washer fluid all year round. Adapt the mixing
ratio to the ambient temperature. At temperatures above freezing:
X Fill up the washer fluid reservoir with a mix-
ture of water and windshield washer con-
centrate, e.g. Summerwash to prevent
smearing.
At temperatures below freezing:
X Fill up the washer fluid reservoir with a mix-
ture of water and windshield washer con-
centrate, e.g. Winterwash if there is a dan-
ger of frost.
This prevents washer fluid from freezing on
the windshield.
