There are several reasons for increased fuel
consumption compared with the table's val-
ues. Examples of this are:
•
The driver's driving style.
•
If the customer has specified wheels larger
than those fitted as standard on the mod-
el's basic version, then resistance increa-
ses.
•
High speed results in increased wind resis-
tance.
•
Fuel quality, road and traffic conditions,
weather and the condition of the car.
Even a combination of the above-mentioned
examples can result in significantly improved
consumption. For further information, please
refer to the regulations referred to
1
.
Large deviations in fuel consumption may arise
in a comparison with the EU driving cycles
1
which are used in the certification of the car
and on which the consumption figures in the
table are based.
To bear in mind
Tips that the driver can use in order to reduce
consumption:
•
Drive gently and avoid unnecessary accel-
eration as well as braking too hard.
•
Drive with the correct air pressure in the
tyres and check this regularly - select ECO
tyre pressure for best results, see the tyre
pressure table on page 388.
•
Choice of tyres can affect fuel consump-
tion - seek advice on suitable tyres from a
dealer.
See further information and more advice on
pages 12 and 284.
See page 288 for general information on fuel.

Official fuel consumption figures are based on two standardised driving cycles in a laboratory environment ("EU driving cycles") all in accordance with EU Directive 80/1268/EEC (Euro 4), EU Regulation
no 692/2008 (Euro 5) and UN ECE Regulation no 101. The regulations cover the driving cycles for urban driving and extra-urban driving. - Urban driving - the measurement starts with cold starting
the engine. The driving is simulated. - Extra-urban driving - the car is accelerated and braked at speeds between 0 and 120 km/h. The driving is simulated. - A car with D2, D3, D4 or D5 engine and
6-speed manual gearbox is started in 2nd gear. The combined driving value given in the table is a combination of urban driving and extra-urban driving, in accordance with applicable legislation.
CO
2
emissions - the exhaust gases are collected in order to calculate the carbon dioxide emissions during the two driving cycles. These are then analysed and give the value for CO
2
emissions.
