General notes !
Engine oil gets dirty in the course of opera-
tion and its quality and volume are gradually
diminished. Regularly check the oil level,
and top up or have it replaced as needed.
Observe the information on approved engine
oils and oil consumption under "Service prod-
ucts and capacities" ( Y page

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

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. Oil dipstick and engine oil filler neck

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
Add windshield washer concentrate to the
washer fluid all year round. Observe the infor-
mation regarding washer fluid under "Service
Products and Capacities"

(Y page 312).

Maintenance and care

X
Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlet grilles.
X Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agents dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
Power washers G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior dam-
age to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Under no circumstances use power wash-
ers in the vehicle interior. The pressurized
water and associated spray produced by the
power washer could cause extensive dam-
age to the vehicle.
! When using high-pressure cleaning equip-
ment, maintain a minimum distance of
approx. 1 ft (30 cm
) between the spray noz-
zle and the vehicle parts. Do not use a
power washer with a round-jet nozzle. You
could damage the vehicle or engine parts.
! Keep the water jet moving constantly
while cleaning. This will avoid causing dam-
age to the vehicle.
Do not point the water jet at:
R door joints
R rear view camera
R air bellows
R brake hoses
R wheel balance weights
R electrical components
R electrical connections R
seals
R drive train, especially not at the inter-
mediate bearing of the propeller shaft
Cleaning the engine !
Water must not enter intake or ventilation
openings. When cleaning with high pressure
water or steam cleaners, the spray must not
be aimed directly at electrical components
or the terminals of electrical lines.
Preserve the engine after the engine has
been cleaned. Protect the belt drive system
from exposure to the preservative agent.
Also observe the information under "Power
washers"

(Y page 265).
Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop.
X Remove impurities immediately, where pos-
sible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
X Remove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Cleaning the windows G
WARNING
You could become trapped by the wind-
shield wipers if they start moving while
cleaning the windshield or wiper blades.
There is a risk of injury. Care

Cleaning the trailer tow hitch H
Environmental note
Dispose of rags soaked in oil and grease in
an environmentally responsible manner.
! Do not clean the ball coupling with a
power washer. Do not use solvents.
! Observe the notes on additional care for
the trailer tow hitch (see the manufacturer's
operating instructions).
You can also have the maintenance work on
the ball coupling and the trailer tow hitch car-
ried out by a qualified specialist workshop. Interior
Cleaning the interior !
When using liquids to clean the vehicle
interior, observe the following points:
R Under no circumstances use power wash-
ers.
R Make sure that no fluids enter or remain
in gaps and cavities.
R Ensure sufficient ventilation when clean-
ing.
R Make sure that the vehicle interior is com-
pletely dry after cleaning. Cleaning the display !
For cleaning, do not use any of the follow-
ing:
R alcohol-based thinner or gasoline
R abrasive cleaning agents
R commercially-available household clean-
ing agents
These may damage the display surface. Do
not put pressure on the display surface
when cleaning. This could lead to irreparable
damage to the display.
X Switch off the display and let it cool down.
X Clean the display surface with a commer-
cially available microfiber cloth and cleaner
for TFT/LCD displays.
X Dry the display surface using a dry micro-
fiber cloth.
Cleaning the plastic trim G
WARNING
Care products and cleaning agents contain-
ing solvents cause surfaces in the cockpit to
become porous. As a result, plastic parts
may come loose in the event of air bag
deployment. There is a risk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.
! Never attach the following to plastic surfa-
ces:
R stickers
R films
R perfume oil container or similar
You could otherwise damage the plastic.
! Do not allow cosmetics, insect repellent or
sunscreen to come into contact with the
plastic trim. This maintains the high-quality
look of the surfaces.
X Wipe the plastic trim and the cockpit with a
damp, lint-free cloth, e.g. a microfiber cloth.
X Heavy soiling: use mild soapy water or care
products and cleaning agents recommended
and approved by Mercedes-Benz. 268

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-

the lamp lenses of the headlamps.
When handling washer fluid, observe the
important safety notes on service products
(Y page

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.
