Vehicle care157If the bonnet is opened during an
Autostop, the engine will be restarted
automatically for safety reasons.
Closing Before closing the bonnet, press the
support into the holder.
Lower the bonnet and allow it to fall
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.
Engine oil

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

The maximum engine oil
consumption is 0.6 l per 600 miles.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 5 minutes.
Pull out the dipstick, wipe it clean, reinsert it fully, pull out and read the
engine oil level.Caution
It is the owner's responsibility to
maintain the proper level of an
appropriate quality oil in the
engine.

Vehicle care197If using a car wash, comply with the
car wash manufacturer's instructions.
The windscreen wiper and rear
window wiper must be switched off.
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 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.
Unpainted plastic body parts must not be treated with wax or polishing
agents.Matt filmed body parts or decor tapes must not be polished, to avoid
gleaming. Do not use hot wax
programmes in automatic car washes
if the vehicle is equipped with these
parts.
Matt painted decor parts, e.g. mirror
housing cover, must not be polished. Otherwise these parts would become agleam or the colour would be
dissolved.
Windows and wiper blades
Switch off wipers before handling in
their areas.
Use a soft lint-free cloth or chamois leather together with window cleaner
and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
