Vehicle care297Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
After towing, unscrew the towing eye.
Insert cap with the upper flange into
the recess and fix cap by pushing.
Appearance care
Exterior care LocksThe locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use a de-icing agent only
when absolutely necessary, as this
has a degreasing effect and impairs
lock function. After using a de-icing
agent, have the locks regreased by a
workshop.
WashingThe paintwork of your vehicle is
exposed to environmental influences.
Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing.
Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can
cause paint damage.If using a vehicle wash, comply with
the vehicle wash manufacturer's instructions. The windscreen wiperand rear window wiper must be
switched off. Remove antenna and
external accessories such as roof
racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Wax painted parts of the vehicle regularly.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damages.Caution
Always use a cleaning agent with
a pH value of four to nine.
Do not use cleaning agents on hot surfaces.

Service and maintenance303Use 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
3 306.
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 3 306.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.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 fluid Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified
interval.
AdBlue Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 187.
