Cleaning the wiper blades and the out-
side of the windscreen G
Risk of injury
Turn the key to position 0in the ignition
lock before cleaning the windscreen or the
wiper blades. There is otherwise a risk of
the windscreen wipers being set in motion
and causing injury. X
Turn the key to position 1(Y page 76)in the
ignition lock.
X Set the windscreen wipers to position u
(Y page 104) on the combination switch.
X Turn the key to position 0(Y page 76)or
remove it when the wiper arms are vertical.
! Only fold the wiper arms away from the
windscreen when they are in a vertical posi-
tion, otherwise you will damage the bonnet.
X Fold the wiper arms away from the wind-
screen until you feel them engage.
X Clean the windscreen and the wiper blades.
X Fold the windscreen wipers back again
before the ignition is switched on.
! Do not clean the wiper blades too often
as this will result in the rubber becoming
porous, leading to wiper noise.
Cleaning the windows !
Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows.
Clean the insides of the windows with a
damp cloth or commercially-available glass
cleaner. Avoid touching the inside of the
rear windscreen and the side windows with hard objects, e.g. ice scrapers or rings. You
could otherwise cause damage to the win-
dows, rear window heating or aerial on the
rear window.
i Anti-glare film retrofitted to the insides of
the windows could interfere with radio or
mobile phone reception, especially if it is
conductive or metal-coated film. Informa-
tion about anti-glare film can be obtained
from any Mercedes-Benz Service Centre.
Cleaning the headlamps X
Clean the plastic lenses of the headlamps
with a damp sponge.
! Only use washer fluid which is suitable
for plastic lenses. Unsuitable washer fluid
could damage the plastic lenses of the
headlamps.

R dry cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvent
You could otherwise scratch or damage the

Notes on service products and capaci-
ties
Service products are:
R fuels (e.g. petrol, diesel)
R lubricants (e.g. engine oil, transmission oil)
R coolant
R brake fluid
R windscreen washer fluid
Mercedes-Benz recommends that you only
use those products which have been tested
and specially approved by Mercedes-Benz for
your vehicle and are listed in the Mercedes-
Benz Owner's Manual in the relevant chapter
since:
R parts and service products are matched
R damage caused by the use of non-approved
service products is not covered by the war-
ranty
You can recognise service products approved
by Mercedes-Benz by the following inscrip-
tion on the containers:
R MB-Freigabe (e.g. MB-Freigabe 229.51)
R MB Approval (e.g. MB Approval 229.51) Other designations or recommendations that
relate to a level of quality or a specification in
accordance with an MB Approval have not
necessarily been approved by Mercedes-
Benz.
You can obtain further information from any
Mercedes-Benz Service Centre. G
Risk of injury
When handling, storing and disposing of
any service products, please observe the
relevant regulations, as you could other-
wise endanger yourself and others.
Keep service products away from children.
To protect your health, do not allow service
products to come into contact with your
eyes or open wounds. See a doctor imme-
diately if any service product is swallowed. H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuels
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heat-
ing* before refuelling. G
Risk of injury
Do not allow fuel to come into contact with
skin or clothing.
Allowing fuels to come into direct contact
with your skin or inhaling fuel vapours is

362 Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too
low, vapour pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving downhill). This would
impair braking efficiency.
Have the brake fluid renewed every two
years with a brake fluid that has been
approved by Mercedes-Benz and have this
confirmed in the Service Booklet. i
There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Windscreen washer system
The washer fluid reservoir holds approxi-
mately 7.3 litres.
The headlamp cleaning system and the wind-
screen washer system are both supplied from
the washer fluid reservoir.
X At temperatures above freezing point:
Top up the washer fluid reservoir with a
mixture of water and windscreen washer
concentrate (Y page 223).
X At temperatures below freezing point:
Top up the washer fluid reservoir with a
mixture of water, antifreeze and wind-
screen washer concentrate (Y page 223).
Adapt the mixing ratio to the outside tem-
peratures. G
Risk of fire
Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washer
concentrate is being handled. Technical data
