Vehicle care243Depending on the engine, the
position of the coolant container may be different.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.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 285.
Brakes
In the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.

After having changed defective fuses,
close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunction may occur.

286Service and maintenanceDexos is the newest engine oil quality
that provides optimum protection for
petrol and diesel engines. If it is
unavailable, engine oils of other listed qualities must be used.
Recommendations for petrol 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
3 290.
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.
Use 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
3 290.
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 on 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 3 290.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
cold regions 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.
