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

Engine oil
Check the engine oil level manually
on a regular basis to prevent damage
to the engine. Ensure that the correct specification of oil is used.
Recommended fluids and lubricants
3 214.
The maximum engine oil
consumption is 0.6 l per 1000 km.
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.
When the engine oil level has
dropped to the MIN mark, top up
engine oil.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out. If the oil exceeds the maximum level, do
not start the vehicle and contact a
workshop.

210Vehicle carea longer time, it would be
damaged by water spotting and
mould growth.All variants:
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 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.
On vehicles with emblem touchpad:
when cleaning with a high-pressure
jet cleaner ensure a minimum
distance of 30 cm when working
around the tailgate 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.
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.
The foldable sunroof must not be
polished or waxed. When using
automatic car washes, select a
programme without wax additives.
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
