Excessive tractive force can
damage the vehicle.

Appearance care
Exterior care Locks
The locks are lubricated at the factory using 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.
WashingThe paintwork of your vehicle is
exposed to environmental influences,
therefore wash your vehicle regularly.
When using automatic vehicle
washes, we recommend one with
textile brushes and a programme
without wax additives.
When doing a hand wash, use clear
water and a soft brush, cleaning in the
grain direction of the textile hood.
Never use a steam-jet or high-
pressure jet cleaner for the soft top or
the engine compartment.Wax painted parts of the vehicle
regularly.
Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can cause paint and fabric damage.
If using a vehicle wash, comply with
the vehicle wash manufacturer's instructions. The windscreen wipermust be switched off. Remove
additional antenna and external
accessories.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damage.
