support into the holder.
Lower the bonnet and allow it to drop into the catch from a low height
(20-25 cm). Check that the bonnet is
engaged.

Vehicle care197Appearance care
Exterior care LocksThe locks are lubricated at the factoryusing 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.
Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing. Restrictions for
filmed or matt painted body parts or decor tapes, see "Polishing and
waxing".
Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can cause paint damage.If using a vehicle wash, comply with
the vehicle wash manufacturer's
instructions. The windscreen wipers
must be switched off and the exterior
mirrors must be folded in. Remove
antenna and external accessories
such as roof racks etc.
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 damages.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
Do not clean the engine compartment with a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use
an ice scraper, and do not clean them
dry.
Polishing and waxing
Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a protective film, making waxing
unnecessary.
