Vehicle care
On vehicles which are washed
frequently in automatic car washes
with underbody washing facility, the
protective wax coating may be
impaired by dirt-dissolving additives.
Check the underbody after washing
and have it waxed if necessary.
Before the start of the cold weather
season, check the PVC coating and
protective wax coating and, if
necessary, have them restored to
perfect condition.
The underbody should be washed
following the end of the cold weather
season to remove any dirt adhering to
the underbody since this may also
contain salt. Check protective wax
coating and, if necessary, have it
restored to perfect condition.
Engine compartment
Areas of the engine compartment that
are painted in the same colour as the
vehicle must be looked after like any
other painted surface.
It is advisable to wash the engine
compartment before and after winter
and preserve it with wax. Cover
alternator and fluid reservoirs with
plastic sheets before washing the
engine.
When washing the engine with a
steam-jet cleaner, do not direct the
steam-jet at components of the
Anti-lock Brake System (ABS), the air
conditioning system
3
or the belt
drive and its components.
Protective wax that has been applied
is also removed during the engine
wash. For this reason, have the
engine, brake system components in
the engine compartment, axle
components with steering, body parts
and cavities thoroughly preserved
with protective wax after the wash.
An engine wash can be performed in
the spring in order to remove dirt that
has adhered to the engine
compartment, which may also have a
high salt content. Check protective
wax layer and make good if
necessary.
