134Driving and operating
When refuelling is complete, replace
the fuel filler cap and turn it clockwise.
Close the fuel filler flap.
Fuel filler cap
Only use genuine fuel filler caps. Diesel-engined vehicles have special fuel filler caps.
Fuel consumption - CO 2-
Emissions
For the values specific to your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
General information The official fuel consumption and
specific CO 2 emission figures quoted
relate to the EU base model with
standard equipment.
Fuel consumption data and CO 2
emission data are determined
according to regulation
715/2007 692/2008 A, taking intoconsideration the vehicle weight in running order, as specified by the
regulation.
The figures must not be taken as a
guarantee for the actual fuel
consumption of a particular vehicle.
Additional equipment may result in
slightly higher results than the stated
consumption and CO 2 figures.
Furthermore, fuel consumption is dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust fitting of towing equipment at
a later date to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Driving characteristics and
towing tips In the case of trailers with brakes,
attach the breakaway stopping cable.
Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements. For trailers with
low driving stability the use of a
stabiliser is recommended.
A maximum speed of 50 mph must
not be exceeded, even in countries
where higher speeds are permitted.
Driving and operating135
If the trailer starts snaking, drive moreslowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 201.
Trailer towing Trailer loads
The permissible trailer loads are
vehicle-dependent and engine-
dependent maximum values which
must not be exceeded. The actual
trailer load is the difference between
the actual gross weight of the trailer
and the actual coupling socket load
with the trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12 %.
The permitted trailer load applies up to the specified incline and up to an
altitude of 1000 metres above sealevel. Since engine power decreases as altitude increases due to the airbecoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10 % for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving on roads with slight inclines (less than 8 %, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 182.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load is specified on the
towing equipment identification plate
and in the vehicle documents. Always aim for the maximum load, especially
in the case of heavy trailers. The
vertical coupling load should never
fall below 25 kg.In the case of trailer loads of
1200 kg or more, the vertical coupling load should not be less than 50 kg.
Rear axle load When the trailer is coupled and the
towing vehicle fully loaded (including
all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Towing equipment audible
warning For vehicles fitted with towing
equipment, when connected to a
trailer the pitch of the audible warning
changes upon operation of the turn
signals.
136Driving and operating
The pitch of the audible warning will
change if a turn signal light on the
trailer or the towing vehicle fails.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While the system is working,keep steering wheel as still as
possible.
Trailer stability assist (TSA) is a
function of the Electronic stability
program (ESP) 3 125.Auxiliary features
