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, the gasoline should
be sulfur-free or very low in 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 damage to
property. Do not refuel or add the following in
the case of gasoline engines:
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.
▷
▷
Leaded gasoline.
The power and consumption specifications re-
fer to operating with RON 98 E10 fuel
Metallic additives, for instance manga-
nese or iron.
When using minimum quality AKI 87 fuel, there
may be knocking noises as well as driving and
acoustic abnormalities. These have no effect
on the engine service life.
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.
