Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
You can have the oil level reading displayed in
the instrument cluster.1.Push button 1 in the turn indicator lever up
or down repeatedly until the appropriate
symbol is shown in the display, accompa-
nied by the word "OIL".
2.Press button 2.
The oil level is checked and the reading dis-
played.

temperature can lead to component damage or
water penetration. Follow the operating instruc-
tions for the steam jet or high-pressure
washer.<
When using high-pressure washers, do
not spray against the sensors and cam-
eras, e.g. of the Park Distance Control or Rear
View Camera, for an extended period and main-
tain a distance of at least 12 in/30 cm.<
Manual car wash
When washing the vehicle by hand, use large
quantities of water and car shampoo if neces-
sary. Clean the vehicle with a sponge or wash-
ing brush, applying light pressure only.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unintentional activation of the
wipers.<
Observe local regulations pertaining to
washing vehicles by hand.<
Headlamps
Do not rub them dry and do not use abrasive or
corrosive cleaning agents.
Remove contamination, such as insects, by
soaking with shampoo or insect remover and
then rinsing with plenty of water.
Thaw ice with a windshield de-icer and do not
use an ice scraper.
Windows
Clean the inside and outside surfaces of the
windows and the mirrors with window cleaner.
Do not clean the mirrors with cleaners
containing quartz.<
Wiper blades
Clean with soapy water and replace regularly to
avoid streaking.
Wax and preservative residue and con-
tamination on the window can lead to
streaking when operating the windshield wip-
ers, leading to premature wear of the wiper
blades and causing the rain sensor to malfunc-
tion.<
Convertible top care
The appearance and life of the convertible top
depend on proper care and operation.
Follow these instructions:
>Do not fold the convertible top into the con-
vertible top box when the top is wet or fro-
zen, as this may cause water spots, mold
stains or chafed areas.
>If water spots occur on the inside headliner
despite precautions, remove them using a
microfiber cloth and interior cleaner.
>If the vehicle is parked in enclosed areas for
extended periods, ensure that there is suffi-
cient ventilation.
>Remove bird droppings immediately, as
their corrosive ingredients attack the con-
vertible top and damage the rubber seals.
To remove stains from the convertible
top, do not use stain removers, paint thin-
ners, solvents, benzine or similar substances.
These substances may damage the rubber
parts. Improper care and cleaning may cause
the convertible top and convertible top seams
to become leaky.<
To remove heavy soiling, use a special convert-
ible top cleaner.
Follow the manufacturer's instructions for use.
After washing the convertible top three to five
times, treat it with an impregnating agent.
Paintwork care
Regular care contributes to value retention and
protects the paintwork against the long-term
effects of damaging substances.
Region-specific environmental influences can
damage the vehicle paintwork. Therefore, it is
important to adapt the frequency and scope of
car care accordingly.
Immediately remove very aggressive sub-
stances, e.g. spilled fuel, oil, grease, tree resin
or bird droppings, to prevent damage to the
paintwork.
