263 Self-help, vehicle care
When washing the engine with a steam jet,
do not direct the jet at components of the
anti-lock braking system, the air
conditioning system, the climate control
system, the auxiliary heater or the belt
drive or its components.
Engine washing also removes subsequently
applied protective wax. Therefore after
washing, have a workshop protect the
engine, parts of the braking system in the
engine bay, axle elements with steering,
body elements and cavities, thoroughly
with protective wax.
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.
Do not use high-pressure jet cleaners.
Underbody
Your vehicle has a factory-applied PVC
undercoating in the wheel arches
(including the longitudinal members) which
provides permanent protection and needs
no special maintenance.
The surfaces of the vehicle underbody not
covered by PVC are provided a durable
protective wax coating in critical areas.
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, so 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.
Caution - commercially available bitumen/
rubber materials can damage the PVC
coating. We recommend that you have
underbody work carried out by a workshop
which knows the prescribed materials and
has experience in the use thereof.
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.
