figures may change if the car is equipped with
extra equipment that affects the car's weight.
The manner in which the car is driven and other
non-technical factors can affect fuel consump-
tion.

The engine can be run with octane ratings of
91, 95 and 98 RON.
When driving in temperatures above +38 ºC,
use of fuel with the highest possible octane
rating is recommended for optimum performan-
ce and fuel economy.
· 98 RON is recommended for maximum
effect and minimum fuel consumption.
· 95 RON can be used for normal driving.
· 91 RON must not be used in 4-cylinder
engines and, in general, should only be used
as an exception. However, the engine will
not be damaged by this fuel grade.
