Only use towing equipment that has been
approved for your vehicle. 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.

Towing equipment with fixed coupling
ball bar3
In the case of trailers/caravans with brake,
attach break-away stopping cable to eye
to right of coupling ball bar. Caravan/trailer towingCaravan and trailer loads
1)
The permissible caravan/trailer loads are
vehicle and engine-dependent maximum
values which must not be exceeded. The
actual caravan/trailer load is the difference
between the actual gross weight of the
caravan/trailer and the actual coupling
socket load with the caravan/trailer
coupled.
The permissible caravan/trailer loads are
specified in the vehicle documents. In
general, they are valid for gradients up to
max. 12 %. The permitted caravan/trailer load applies
up to the specified incline and up to an
altitude of 1000 metres above sea level.
Since engine power decreases as altitude
increases because of the air becoming
thinner, therefore reducing climbing ability,
the permitted towing weight also
decreases by 10 % for every 1000 metres
of additional altitude. The towing 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 3182. Coupling socket load
The coupling socket load is the load
exerted by the trailer/caravan on the
coupling ball. It can be varied by changing
the weight distribution when loading the
trailer/caravan.
The maximum permissible coupling socket
load (50 kg) 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 caravans/trailers. The coupling
socket load should never fall below 25 kg.
When measuring the coupling socket load,
make sure that the drawbar of the loaded
trailer/caravan is at the same height as it
will be when the trailer/caravan is coupled
with the towing vehicle loaded. Particularly
important for trailers/caravans with
tandem axle.
Rear axle load during towing
The permissible axle loads must not be
exceeded. 1)Observe national regulations.

If the prescribed tyre pressure is not
reached within 10 minutes, remove the
tyre repair kit. Move the vehicle by one
tyre rotation. Attach the tyre repair kit
again and continue the filling
procedure for 10 minutes. If the
prescribed tyre pressure is still not
reached, the tyre is too damaged to
repair. Contact a workshop. Drain excess tyre pressure with the
button over the pressure indicator.
Do not run the compressor for more
than 10 minutes - see "Important
information" 3145.
15. Detach the tyre repair kit. Screw the
filler hose to the free connection on the
sealant bottle. This prevents sealant
leakage. Stow the tyre repair kit in the
luggage compartment.
16. Wipe away any sealant spill with a
cloth.
17. Collapse the warning triangle and stow
it in the luggage compartment or
stowage compartment 3133.
18. Take the supplied sticker indicating
maximum permitted speed and affix
it in the driver’s field of view.
19. Continue driving immediately to allow
the sealant to distribute evenly
throughout the tyre. Stop after approx.
10 km (no more than 10 minutes) and
check tyre pressure. Screw the
compressor air hose directly onto the
tyre valve (see Fig. 15798 T).

If tyre pressure is more than 1.3 bar,
adjust to the prescribed value. Repeat
the procedure until there is no more
pressure loss.
If the tyre pressure has dropped below
1.3 bar, the vehicle must not be used.
Contact a workshop for assistance.
20. Stow the tyre repair kit 3142.

Self-help, vehicle care
Underbody
Some areas of the vehicle underbody have
a PVC undercoating while other critical
areas have a durable protective wax
coating.
After the underbody is washed, check the
underbody and have more protective wax
applied if necessary.
Bitumen/rubber materials could damage
the PVC coating. Have underbody work
carried out by a workshop.
Before and after winter, wash the
underbody and have the protective wax
coating checked. Natural gas system3
When cleaning the engine or underbody
with a steam jet or high pressure jet
cleaner, do not aim the jet at components
of the natural gas system. In particular, the
natural gas tanks and the pressure valves
at the vehicle underbody and bulkhead in
the engine compartment must be
protected from the pressurised spray.
In addition, these components must not be
treated with chemical cleaners or waxes.
Have natural gas system components
cleaned by a workshop that is authorised
to maintain natural gas vehicles.
Towing equipment
Do not clean the coupling ball bar with a
steam-jet or high-pressure jet cleaner.
