Malfunctions resulting from paraffin sep-
aration can only be rectified by heating the
entire fuel system. Park the vehicle in a
heated garage, for example.
To prevent operating problems, diesel with
better flow qualities is available during the
winter months. You can obtain information at
the gas station or from your fuel supplier.
Your vehicle is equipped with a fuel preheat-
ing system. This improves the flow properties
of the diesel by approximately 46 ‡ (8 †).
ULTRA-LOW SULFUR DIESEL can be used
without risk of malfunction down to an out-
side temperature of approximately 14 ‡
(Ò10 †).
Fuel additives
!
Do not add gasoline or kerosene to diesel
fuel to improve its flow characteristics.
Gasoline or kerosene impairs the lubricat-
ing properties of the diesel fuel. This can
result in damage to the fuel injection sys-
tem, for example.
Information on fuel consumption
H
Environmental note
CO
2
(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO
2
emissions are directly related to
fuel consumption and therefore depend on:
R
efficient use of the fuel by the engine
R
driving style
R
other non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO
2
emis-
sions by driving carefully and having it serv-
iced regularly.
Fuel consumption depends on:
R
the vehicle version
R
the style of driving
R
the operating conditions
R
the type or quality of the fuel used
The vehicle will use more fuel than usual in the
following situations:
R
at very low outside temperatures
R
in city traffic
R
during short journeys
R
on mountainous terrain
R
when towing a trailer
To keep fuel consumption low, observe the
advice in the "Protection of the environment"
section (Y page 23).
The following components of the different
vehicle versions influence fuel consumption:
R
tire sizes, tire tread, tire pressure, tire con-
dition
R
body
R
transmission ratios for the drive assem-
blies
R
additional equipment (e.g. air-conditioning
system, auxiliary heating system)
For these reasons, the actual consumption
figures for your vehicle may deviate from the
consumption figures determined according
to EU Directive 80/1268/EEC.
Data concerning fuel consumption are recor-
ded in the on-board computer; use the steer-
ing wheel buttons to call up the Trip com-
puter menu (Y page 195).
Diesel Exhaust Fluid (DEF)
General notes
!
Only use DEF in accordance with
ISO 22241. The exhaust gas aftertreatment
system may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage caused by the use of other reduc-
ing agents will invalidate the New Vehicle
Limited Warranty.
