Vehicle equipment  
This chapter describes all the standard equip‐  
ment, national-market-specific equipment and  
optional extras offered in the model series.  
Consequently, you will find that it contains de‐  
scriptions of items not available in a particular  
vehicle on account of a combination of options,  
for example, or the constraints applying to cer‐  
tain national-market versions. This also applies  
to safety-relevant functions and systems.  
Minimum grade  
Unleaded petrol with RON 91.  
Minimum grade  
Do not refuel with petrol below the speci‐  
fied minimum quality, as otherwise engine op‐  
eration is not ensured.◀  
Country-specific regulations must be observed  
when using the corresponding functions and  
systems.  
Petrol  
For optimal fuel economy, the petrol should be  
sulphur-free or as low in sulphur content as  
possible.  
Fuels which are labelled at the fuel pump as  
containing metals may not be used.  
Only fill up with lead-free petrol without  
metallic additives  
Do not fill up with leaded petrol or petrol with  
metallic additives such as manganese or iron,  
otherwise permanent damage can be caused  
to the catalytic converter and other compo‐  
nents.◀  
You can fill up with fuels with a maximum pro‐  
portion of ethanol of 10 %, i.e. E10.  
Do not refuel with ethanol E85  
Do not use E85, i.e. fuel that consists of  
85 % ethanol, or flex fuel, as otherwise the en‐  
gine and fuel supply system will be damaged.◀  
The engine has anti-knock control. This means  
that different grades of petrol can be used.
