Vehicle features and options
This chapter describes all standard, country-
specific and optional equipment offered with
the series. It also describes features and func-
tions that are not necessarily available in the
vehicle, e.g., due to the selected options or
country versions. This also applies to safety-
related functions and systems. When using
these functions and systems, the applicable
laws and regulations must be observed.
Fuel recommendation
General information
Depending on the region, many filling stations
sell fuel that has been customized to winter
or summer conditions. Fuel that is available
in winter, for instance helps make a cold start
easier.
Gasoline
General information
For the best fuel efficiency, the gasoline should
be sulfur-free or very low in sulfur content.
Fuels that are marked on the gas pump as
containing metal must not be used.
Fill up using fuel with a maximum ethanol con-
tent of 10 %, e.g., E10.
To achieve nominal values for mileage and
consumption, follow the specified fuel quality
in the sales literature.
The use of fuels of minimum quality has no
influence on the service life of the engine.

Safety information
Caution
The use of poor-quality fuels may result in
harmful engine deposits or damage. Addi-
tionally, problems relating to drivability, start-
ing and stalling, especially under certain envi-
ronmental conditions such as high ambient
temperature and high altitude, may occur.
If drivability problems are encountered, we
recommend switching to a high quality gaso-
line brand and a higher octane grade — AKI
number — for a few tank fills. To avoid harm-
ful engine deposits, it is highly recommended
to purchase gasoline from Top Tier retailers.
Failure to comply with these recommenda-
tions may result in the need for additional
maintenance.
NOTICE
Even small quantities of the wrong fuel or
wrong fuel additives can damage the fuel
system and engine. Furthermore, the cat-
alytic converter is permanently damaged.
There is a risk of damage to property. Do
not refuel or add the following in the case of
gasoline engines:
▷ Leaded gasoline.
▷ Metallic additives, for instance manga-
nese or iron.
Do not press the Start/Stop button after refu-
eling with the wrong fuel. Contact an author-
ized service center or another qualified serv-
ice center or repair shop.
