300Vehicle care
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
The lashing eye at the rear
underneath the vehicle must never be used as a towing eye.
Attach a tow rope – or even better a
tow bar – to the towing eye.
The towing eye must only be used for
towing and not for recovering a
vehicle.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
After towing, unscrew the towing eye.
Insert cap at the bottom and engage.
Appearance care
Exterior care
Locks The locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use 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.
Washing
The 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.

Service and maintenance307Brake and clutch fluidOver time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified interval.
Washer fluid Use only washer fluid approved for
the vehicle to prevent damage of wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
AdBlue Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 207.
