Vehicle care
Cleaning and care of the vehicle
Notes
Regular and proper care will help to maintain
the value of your vehicle.
GWarning!
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container. Always open your

! When cleaning the vehicle, do not use
scouring agents. Never apply strong force
and only use a soft, wet cloth or sponge.
Otherwise you may scratch or damage the
surface to be cleaned.
While in operation, even while parked, your
vehicle is subjected to varying external
influences which, if gone unchecked, can
attack the paintwork as well as the vehicle
underbody and cause lasting damage.
Such damage is caused not only by extreme
and varying climatic conditions, but also by:
R Air pollution
R Road salt
R Tar
R Gravel and stone chipping
To avoid paint damage, you should
immediately remove:
R Grease and oil
R Fuel
R Coolant
R Brake fluid
R Bird droppings
R Insects
R Tree resins etc.
Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above
adverse influences.260Vehicle careOperation
