Move the safety catch (located
slightly right of centre) sideways to
the left vehicle side and open the
bonnet.
The bonnet is held open
automatically by a lifter.
If the bonnet is opened during an Autostop, the engine will be restarted automatically for safety reasons.
Stop-start system 3 117.
Closing
Lower the bonnet and allow it to fall
into the latch from a low height
(approx. 30 cm). Check that the
bonnet is engaged.
Caution
Do not press the bonnet into the
latch, to avoid dents.
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 3 181.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 10 minutes.
Pull out the dipstick, wipe it clean, insert it to the stop on the handle, 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.
Caution
Do not allow the engine oil level to drop below the minimum level!

Vehicle care177Appearance 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
and rear window wiper 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.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.
Unpainted plastic body parts must not
be treated with wax or polishing
agents.
