Adding coolant
X
If the coolant drops under the minimum
mark on coolant expansion tank 0044, add
coolant to the maximum mark.
Observe the information on coolant mix-
ture ratio and water quality in the "Techni-
cal data" section ( Ypage 329). To prevent
damage to the engine cooling system, use
only approved corrosion inhibitor/anti-
freeze that comply with the Mercedes-Benz
Specifications for Service Products.
X Replace cap 0043and turn it clockwise to
tighten.
X Start the engine.
X After approximately 5 minutes, switch off
the engine and allow it to cool down.
X Check the coolant level again and add cool-
ant if necessary.
X Close the hood. Brake fluid

WARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the labels
of the respective original containers. Always
store service products sealed in their original
containers. Always keep service products out
of the reach of children.
Brake fluid is hazardous to health. Also
observe the safety notes in the "Service prod-
ucts and capacities" section (Y page 320).G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident. You should have the brake fluid renewed at
the specified intervals.
! Brake fluid corrodes paint, plastic and
rubber. If paint, plastic or rubber has come
into contact with brake fluid, rinse with
water immediately.
Have the brake fluid renewed every 2 years
at a qualified specialist workshop. Observe
the information on brake fluid in the "Techni-
cal data" section ( Ypage 328). Check the brake fluid level regularly, e.g.
weekly or when refueling.
Checking the brake fluid level
X
Stop your vehicle as far away from traffic
as possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page 250).
X Check the brake fluid level.
The brake fluid level is correct if the level is
between the MIN mark and MAX mark on
brake fluid reservoir 0043.
X Close the hood.
! If the brake fluid level in the brake fluid
reservoir has fallen to the MIN mark or
below, check the brake system immedi-
ately for leaks. Also check the thickness of
the brake linings. Visit a qualified specialist
workshop immediately.
Do not add brake fluid. This does not cor-
rect the malfunction. 256

Important safety notes G
WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Take care not to spill any coolant on
painted surfaces. You could otherwise
damage the paintwork.
When handling, storing and disposing of cool-
ant and antifreeze, please observe the rele-
vant regulations and the safety notes in the
"Service products and capacities" section
(Y page 320). Coolant additive with corrosion/anti-
freeze protection !
Use only approved antifreeze/corrosion
inhibitor that complies with MB Specifica-
tion for Service Products, Sheet Number
325. Using other, non-approved anti-
freeze/corrosion inhibitors may cause
damage to the coolant system and reduce
the engine's service life.
Coolant is a mixture of water and antifreeze/
corrosion inhibitor. It performs the following
tasks:
R corrosion protection
R antifreeze protection
R raises the boiling point
When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection. Coolant
must be used in the system all year round to
ensure anti-corrosion protection and a raised
boiling point – even in countries with high
outside temperatures.
To prevent damage to the engine cooling sys-
tem, use only approved corrosion inhibitor/
antifreeze that comply with the Mercedes-
Benz Specifications for Service Products. You
will find information about approved corro-
sion inhibitor/antifreeze for your vehicle in
the Maintenance Booklet.
We recommend corrosion inhibitor/anti-
freeze that meets the requirements in MB
Specifications for Service Products Sheet
Number 325.
Check the antifreeze/corrosion inhibitor con-
centration in the coolant every six months.
The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
R be at least 50%. This way, the engine cool-
ing system is protected 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. Service products and capacities

If there has been coolant loss, do not refill
only with water. If the vehicle has lost coolant,
add equal parts water and corrosion inhibi-
tor/antifreeze additive. The water used as
part of the coolant mixture must fulfill certain
requirements; these are usually fulfilled by
drinking water. If the water quality is not suf-
ficient, you must treat the water.
Further information can be obtained at any
qualified specialist workshop.

Washer fluid
Important safety notes G
WARNING
Windshield washer concentrate is highly flam-
mable. If it comes into contact with hot engine
components or the exhaust system it could
ignite. There is a risk 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 damage the plastic lenses of the
headlamps.
Observe also the safety notes in the "Service
products and capacities" section.
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. 330
