tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This

tems. The respectively applicable country provi‐
sions must be observed when using the respec‐

Fuel recommendation
General information
Depending on the region, many gas stations
sell fuel that has been customized to winter or
summer conditions. Fuel that is available in
winter helps make a cold start easier, for exam‐
ple.
Information
ATTENTION
Even fuels that conform to the specifica‐
tions can be of low quality. This may cause en‐
gine problems, e.g., poor engine start-up be‐
havior, poor handling and/or poor
performance. There is a risk of damage to
property. In case of engine problems, switch
gas stations or use a brand name fuel with a
higher octane rating.◀
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 con‐
taining metal must not be used.
Fuels with a maximum ethanol content of
25 %, i. e. E10 or E25, may be used for refuel‐
ing.
Ethanol should meet the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
