Fuel additives
! Do not use any fuel additive. Fuel additives
may cause malfunctions and engine failure.
Do not add any petrol, kerosene or flow
improvers to diesel fuel to improve its flow
characteristics. Flow improvers actually
impair the lubricity of the diesel fuel. This can
cause damage to the injection system, for
example.
Information on fuel consumption
H
Environmental note
CO (carbon dioxide) is the gas which scien-
2
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO emissions are directly related to
2
fuel consumption and therefore depend on:
efficient use of the fuel by the engine
R
driving style
R
other non-technical factors, such as envi-
R
ronmental influences, road conditions or
traffic flow
You can minimise your vehicle's CO
sions by driving carefully and having it serv-
iced regularly.
Only for certain countries: the respective cur-
rent consumption and emission values of your
vehicle can be found in the COC papers (EC
CERTIFICATE OF CONFORMITY). These docu-
ments are supplied when the vehicle is deliv-
ered.
Consumption figures were found in the currently
valid respective version:
for vehicles up to and including the Euro 4
R
standard according to EU Directive
80/1268/EEC
for vehicles from the Euro 5 standard accord-
R
ing to regulation (EC) no. 715/2007
for vehicles from the Euro 6 standard accord-
R
ing to regulation (EC) no. 595/2009
Fuel consumption depends on:
the type of vehicle
R
the style of driving
R
the operating conditions
R
the type or quality of the fuel used
R
Service products and capacities
The vehicle will use more fuel than usual in the
following situations:
at very low outside temperatures
R
in urban traffic
R
during short journeys
R
in mountainous terrain
R
when towing a trailer
R
Observe the advice in the "Protection of the
environment" section to keep fuel consumption
Y
low ( page 29).
The following components of the different vehi-
cle versions influence fuel consumption:
tyre sizes, tyre tread, tyre pressure, tyre con-
R
dition
transmission ratios for the drive assemblies
R
additional equipment (e.g. air-conditioning
R
system, auxiliary heating system)
For these reasons, the actual consumption fig-
ures for your vehicle may deviate from the con-
sumption figures determined according to EU
Directive 80/1268/EEC.
Details on fuel consumption can be called up in
the on-board computer (
