Secure the bonnet support.
If the bonnet is opened during an
Autostop, the engine will be restarted automatically for safety reasons.

into the latch from a low height
(20-25 cm). Check that the bonnet is engaged.Caution
Do not press the bonnet into the
latch, to avoid dents.

on a regular basis to prevent damage
to the engine. Ensure that the correct specification of oil is used.

consumption is 0.6 litres per 1000 km.

230Vehicle careWax painted parts of the vehicleregularly.
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 wiper must 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.Caution
Always use a cleaning agent with
a pH value of four to nine.
Do not use cleaning agents on hot surfaces.
Caution
After washing or cleaning, the softtop must be completely dried
before opening. If a wet soft top
remains opened for a longer time,
it would be damaged by water
spotting and mould growth.
When cleaning with a high-pressure
jet cleaner ensure a minimum
distance of 30 cm to the rear brand
emblem to prevent unintended
unlocking.
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.
Have the door hinges of all doors
greased by a workshop.
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 painted parts of 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.
Soft top as well as plastic body parts
must not be treated with wax or
polishing agents.
Windows and windscreen wiper
blades
Use a soft lint-free cloth or chamois
leather together with window cleaner and insect remover.
