Ride control systems
Traction Control system The Traction Control system (TC) is a component part of the Electronic
Stability Control (ESC) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
The Traction Control system is
operational as soon as the ignition is
switched on and control indicator b
extinguishes in the instrument cluster.
A corresponding message also
appears in the Driver Information
Centre 3 103.

Fuel for diesel engines The Diesel engines are compatible
with fuels that conform to current and future European standards and can
be obtained from filling stations:
Diesel fuel that meets standard
EN590 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 7 % Fatty Acid Methyl Ester).
162Driving and operatingDiesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10 % Fatty Acid
Methyl Ester).
If travelling in countries outside the
European Union, occasional use of
Euro-Diesel fuel with a sulphur
concentration below 50 ppm is
possible.Caution
Frequent usage of diesel fuel containing more than 15 ppm
sulphur will cause severe engine
damage.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
The flow and filterability of diesel fuels are temperature-dependent. When
temperatures are low, refuel with
diesel fuel with guaranteed winter
properties.
Diesel fuel filter 3 175.
Diesel fuel system bleeding 3 175.
Low temperature operation
At temperatures below 0 °C, some
diesel products with biodiesel blends
may clog, freeze or gel, which may
affect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0 °C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20 °C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage to the fuel
injection system.Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers.
Vehicles with stop-start system:
The engine must be switched off
and the ignition key removed, to avoid risk of engine being
restarted automatically by the
system.
Switch off any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Driving and operating163A label with symbols at the fuel filler
flap is indicating the allowed fuel
types. In Europe the pump nozzles of
the filling stations are marked with
these symbols. Refuel only the
allowed fuel type.Caution
In case of misfuelling, do not
switch on ignition.
Note
To ensure the fuel level is displayed
correctly, the ignition must be
switched off before refuelling. Avoid
minor fuel top-ups (e.g. less than
5 l) to ensure accurate readings.
The fuel filler flap is located on the left-
hand side of the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked and the left- hand door is opened.
Note
Do not open the left-hand sliding
side door during refuelling.

General information
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment. Only use
towing equipment that has been
approved for your vehicle.
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 80 km/h must
not be exceeded, even in countries
where higher speeds are permitted.If the trailer starts snaking, drive more slowly, 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 3 216.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle 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 m above sea level.Since engine power decreases as
altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10% for every 1000 m 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
3 210.
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.
