The fuel filler cap can be retained in
the holder on the inside of the fuel

Fuel consumption - CO
Emissions
The determination of fuel
consumption is regulated by
European directive
715/2007 692/2008 A.
The directive is oriented to actual
driving practices: Urban driving is
rated at approx. 1 / and extra urban
3
driving at approx. 2 / . Cold starts and
3
acceleration phases are also taken
into consideration.
The specification of CO emission is
2
also a constituent of the directive.
The figures given must not be taken
as a guarantee for the actual fuel
consumption of a particular vehicle.
Furthermore, fuel consumption is
dependent on personal driving style
as well as road and traffic conditions.
All values are based on the EU base
model with standard equipment.
The calculation of fuel consumption
takes into account the vehicle's kerb
weight, ascertained in accordance
with the regulations. Optional
-
equipment may result in slightly
2
higher fuel consumption and CO
emission levels and a lower maximum
speed.
