Vehicle features and
options
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features and functions that are
not necessarily available in your vehicle, e.g., due
to the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. When using these functions and systems,
the applicable laws and regulations must be ob‐
served.
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 win‐
ter, 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 con‐
taining metal must not be used.
Fuels with a maximum ethanol content of 25 %,
i. e. E10 or E25, may be used for refueling.
Ethanol should meet the following quality stan‐
dards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
Safety information
CAUTION
The use of poor-quality fuels may result in
harmful engine deposits or damage. Addition‐
ally, problems relating to drivability, starting and
stalling, especially under certain environmental
conditions such as high ambient temperature
and high altitude, may occur.
If drivability problems are encountered, we rec‐
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI num‐
ber — for a few tank fills. To avoid harmful en‐
gine deposits, it is highly recommended to pur‐
chase gasoline from Top Tier retailers.
Failure to comply with these recommendations
may result in the need for additional mainte‐
nance.
NOTICE
Even small quantities of the wrong fuel or
wrong fuel additives can damage the fuel sys‐
tem and engine. Furthermore, the catalytic
converter is permanently damaged. There is a
risk of damage to property, among other poten‐
tial damage. Do not refuel or add the following
in the case of gasoline engines:
▷ Leaded gasoline.
▷ Metallic additives, for instance manganese
or iron.
Do not press the Start/Stop button after refuel‐
ing with the wrong fuel. Contact a dealer’s serv‐
ice center or another qualified service center or
repair shop.
