Operating fluids
Vehicle features and options
This chapter describes model-specific
equipment, systems, and functions that are
currently available, or may become available
in the future, even if they are not present in
the vehicle.
Additional information:
Vehicle equipment, refer to page 8.
Fuel recommendation
General information
Depending on the region, many filling sta-
tions 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.
Fuels with a maximum ethanol content of
10 %, i.e., E10, may be used for refueling.
The power and consumption specifications
correspond to operation with 98 RON E10
fuel.
Knocking noises and driving/acoustic prob-
lems may occur when using minimum qual-
ity fuel, e.g., 87 AKI, or fuel with an ethanol
content of more than 10 % to max. 15 %.
These have no effect on the engine service
life.
Safety information
Caution
The use of poor-quality fuels may result
in harmful engine deposits or damage.
Additionally, problems relating to drivabil-
ity, starting and stalling, especially under
certain environmental conditions such as
high ambient temperature and high alti-
tude, may occur.
If drivability problems are encountered,
we recommend switching to a high quality
gasoline brand and a higher octane grade
— AKI number — for a few tank fills. To
avoid harmful 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.
Warning
Even small quantities of the wrong fuel or
wrong fuel additives can damage the fuel
system and engine. Furthermore, the cat-
alytic converter can be permanently dam-
aged. There is a risk of injury and risk
of damage to property. Do not refuel or
add the following in the case of gasoline
engines:
– Leaded gasoline.
– Metallic additives, for instance man-
ganese or iron.
Do not turn on standby after refueling
with the wrong fuel. Contact an authorized
service center or another qualified service
center or repair shop.
