When checking the oil level:
R
park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement.
Checking the oil level using the oil dip-
stick Example: vehicles with a petrol engine
Example: vehicles with a diesel engine
X
Pull oil dipstick :out of the oil dipstick
tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide
tube to the stop, and take it out again.
If the level is between MIN mark =and
MAX mark ;, the oil level is correct.
X If the oil level has dropped to MIN mark
= or below, add 1.0 litre of engine oil. Adding engine oil G
WARNING
If engine oil comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any engine oil on hot
engine parts. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a
service system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
Centre.
Damage to the engine or exhaust system is
caused by the following:
R using engine oils and oil filters that have
not been specifically approved for the
service system
R changing the engine oil and oil filter after
missing the change interval required by
the service system
R using engine oil additives
! Do not add too much oil. Topping up with
too much engine oil can result in damage
to the engine or to the catalytic converter.
Have excess engine oil siphoned off. Engine compartment

Information abou
tService Resetting the ASSYST PLUS service inter-
val display
!
If the ASSYST PLUS service interval dis-
play has been inadvertently reset, this set-
ting can be corrected at a qualified special-
ist workshop.
Have service work carried out as described
in the Service Booklet. This may otherwise
lead to increased wear and damage to the
major assemblies or the vehicle.
Aq ualified specialist workshop, e.g. a
Mercedes-Ben zService Centre, will reset the
ASSYST PLUS service interval display after
the service work has been carried out. You
can also obtain further information on main-
tenance work, for example.
Special service requirements
Arduous operating conditions or increased
loads on the vehicle will require some service
work to be performed more often than for a
vehicle in normal use. Such arduous condi-
tions include regular city driving with frequent
intermediate stops and use in mountainous
terrain or on poor road surfaces.
For example, if the vehicle is used under ardu-
ous operating conditions, have air filters,
engine oil and oil filters changed frequently
and chec kthe wheels often.F urther informa-
tion can be obtained at a qualified specialist
workshop, e.g. a Mercedes-Ben zService
Centre.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's curren ttelephone numbers
for use when you are abroad are to be found

WARNING
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Always maintain a distance of at least
30 cm between the vehicle and the high- pressure cleaner nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, roof gaps, joints etc.
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
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
possible, 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.

Cleaning the plastic trim G
WARNING
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as aresult plastic
parts may break away and be thrown around
the interior when an airbag is deployed, which
may result in severe injuries.
! Do not affix the following to plastic surfa-
ces:
R stickers
R films
R scented oil bottles or similar items
You could otherwise damage the plastic.
! Do not allow cosmetics, insect repellent
or sunscreen to come in contact with the plastic trim
.This maintains the high-quality
look of the surfaces.
X Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfibre cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
The surface may change colour tempora-
rily. Wait until the surface is dry again.
