Vehicle care137Bonnet
Opening
Pull the release lever and return it to
its original position.
Pull the safety catch, located slightly
left of centre, and open the bonnet.
Pull up the support rod from its holder,
then secure it in the right side hook on the underside of the bonnet.
If the bonnet is opened during an Autostop, the engine will be restarted
automatically for safety reasons.
Closing
Before closing the bonnet, press the
support into the holder.
Lower the bonnet and allow it to drop into the catch. Check that the bonnet
is engaged.
Engine oil
Check the engine oil level manually
on a regular basis to prevent damage
to the engine.
Ensure that the correct specification
of oil is used. Recommended fluids
and lubricants 3 176.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 10 minutes.

Recommended fluids and
lubricants
Only use products that meet the
recommended specifications.
Damage resulting from the use of
products not in line with these
specifications will not be covered by
the warranty.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 diesel engines. If it is unavailable,
engine oils of other listed qualities
must be used.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 181.
Topping up engine oil
Engine oils of different manufacturers and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 181.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 3 181.
All of the recommended viscosity grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free 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
