Driving and operating2639Danger
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.
A 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.
The fuel tank filler neck with bayonet
cap is located on the left front side of
the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked and the door is opened. Open the fuel filler flap by
hand.
9 Danger
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.
Capacities 3 315.
Depending on vehicle, unlock fuel
filler cap using the key.

264Driving and operatingTrailer 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.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 3 315.
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 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
3 314.
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.
