Safety information
Vehicle features and options
This chapter describes model-specific equip-
ment, systems, and functions that are currently
available, or may become available in the fu-
ture, even if they are not present in the vehicle.
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.
Additional information:
Vehicle equipment, refer to page 8.
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.
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.
Failure to comply with these recommenda-
tions may result in the need for additional
maintenance.
Gasoline
Warning
General information
For the best fuel efficiency, gasoline should be
sulfur-free or have a low sulfur content.
Even small quantities of the wrong fuel or
wrong fuel additives can damage the fuel
system and engine. Furthermore, the cata-
lytic converter can be permanently damaged.
There is a risk of injury and risk of property
damage. Do not refuel or add the following in
the case of gasoline engines:
Do not use any fuels that contain metal, as
indicated by the label on the gas pump.
Fuels with a maximum ethanol content of
10 %, i.e., E10, may be used for refueling.
▷
▷
Leaded gasoline.
The power and consumption specifications
correspond to operation with 98 RON E10 fuel.
Metallic additives, for instance manga-
nese or iron.
Knocking noises and driving/acoustic problems
may occur when using minimum quality 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.
Do not turn on standby after refueling with
the wrong fuel. Contact an authorized service
center or another qualified service center or
repair shop.

Engine oil
Fuel that does not meet the minimum quality
requirements can cause the engine to mal-
function or become damaged. There is a risk
of property damage. Do not fill with fuel that
does not comply with the minimum quality.
Principle
The engine oil consumption and engine oil
properties depend on the driving style and op-
erating conditions.
Therefore, regularly check the engine oil level
after refueling by taking a detailed measure-
ment.
NOTICE
The engine oil consumption may increase in
the following situations, for example:
Incorrect fuels can damage the fuel system
and the engine. There is a risk of property
damage. Do not use fuels with a higher etha-
nol content than recommended. Do not refuel
with fuels containing methanol, e.g. M5 to
M100.
