Vehicle care183The engine oil filler cap is located on
the camshaft cover.Caution
Overfilled engine oil must be
drained or suctioned out. If the oil exceeds the maximum level, do
not start the vehicle and contact a
workshop.
Capacities 3 233.
Fit the cap on straight and tighten it.
Engine coolant The coolant provides freeze
protection down to approx. -30 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -40 °C.
Caution
Only use approved antifreeze.
Coolant and antifreeze 3 221.
Coolant levelCaution
Too low a coolant level can cause
engine damage.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Power steering fluid
Caution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap / dipstick
or from entering the reservoir.

Vehicle care219Operate the rear carrier system
periodically if not in regular use, in
particular during winter.
Interior care
Interior and upholstery
Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of
heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using a soft damp cloth. If necessary use a
weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.Clean seat belts with lukewarm water or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, e.g. zips, belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior
cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.

Service information In order to ensure economical and
safe vehicle operation and to
maintain the value of your vehicle, it
is of vital importance that all
maintenance work is carried out at the proper intervals as specified.
The detailed, up-to-date service
schedule for your vehicle is available
at the workshop.
Service display 3 86.
European service intervals
Maintenance of your vehicle is
required every 20,000 miles or after
one year, whichever occurs first, unless otherwise indicated in theservice display.
A shorter service interval can be valid for severe driving behaviour, e.g. for
taxis and police vehicles.
The European service intervals are
valid for the following countries:Andorra, Austria, Belgium, Bosnia-
Herzegovina, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany,
Greece, Greenland, Hungary,
Iceland, Ireland, Italy, Latvia,
Liechtenstein, Lithuania,
Luxembourg, Macedonia, Malta,
Monaco, Montenegro, Netherlands,
Norway, Poland, Portugal, Romania, San Marino, Serbia, Slovakia,
Slovenia, Spain, Sweden,
Switzerland, United Kingdom.
Service display 3 86.
International service intervals
Maintenance of your vehicle is
required every 10,000 miles or after
one year, whichever occurs first.
Additional engine oil and filter change is indicated by the engine oil life
system, when required earlier than
maintenance.
Severe operating conditions exist if
one or more of the following
circumstances occur frequently: Cold starting, stop and go operation, trailer operation, mountain driving, driving
on poor and sandy road surfaces,
Page 223 of 253

Service and maintenance221increased air pollution, presence of
airborne sand and high dust content,
driving at high altitude and large
variations of temperature. Under
these severe operating conditions,
certain service work may be required more frequently than the regularservice interval.
The international service intervals are
valid for the countries which are not
listed in the European service
intervals.
Service display 3 86.
Confirmations
Confirmation of service is recorded in the Service and warranty booklet.
The date and mileage is completed
with the stamp and signature of the servicing workshop.
Make sure that the Service and
warranty booklet is completed
correctly as continuous proof of
service is essential if any warranty or goodwill claims are to be met, and is
also a benefit when selling the
vehicle.Recommended fluids,
lubricants and parts
Recommended fluids andlubricants
Only use products that meet the
recommended specifications.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for gasoline and diesel engines. If it isunavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 225.
Topping up engine oilCaution
In case of any spilled oil, wipe it up and dispose it properly.
Engine oils of different manufacturersand brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Page 224 of 253

222Service and maintenanceUse of engine oils for all petrol
engines with only ACEA quality is
prohibited, since it can cause engine
damage under certain operating
conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 225.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature
viscosity.
Select the appropriate viscosity grade
depending on the minimum ambient
temperature 3 225.All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional
coolant additives will be rejected.Washer fluid
Use only washer fluid approved for
the vehicle to prevent damage of
wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
Brake and clutch fluidOver time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.
