containing solutions etc.), acidic or
highly alkaline media or abrasive
pads. Do not apply wax or polishing
agents to the sunroof.

a touch-up pen before rust forms. Have more extensive damage or rust
areas repaired by a workshop.
Underbody
Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.After the underbody is washed, check
the underbody and have it waxed if
necessary.

drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
