Driving and operating183Fit protective cap to prevent the
penetration of foreign bodies into the
filler opening and the system.9 Warning
Due to the system design, an
escape of liquid gas after
releasing the locking lever is
unavoidable. Avoid inhaling.
9 Warning
The liquid gas tank should only be
filled to 80% capacity, for safety
reasons.
The multivalve on the liquid gas tank
automatically limits the fill quantity. If
a larger quantity is added, we
recommend not exposing the vehicle
to the sun until the excess amount
has been used up.
Fuel filler cap
Only use genuine fuel filler caps. Diesel-engined vehicles have special fuel filler caps.
Trailer hitch
General information
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.
The bulb outage detection function for
trailer brake light cannot detect a
partial bulb outage. E.g. in case of
four bulbs with a power of 5 W each,
the function only detects lamp outage when only a single 5 W lamp remains
or none remain.
Fitting of towing equipment could
cover the opening of the towing eye. If this is the case use the coupling ball bar for towing. Always keep the
coupling ball bar in the vehicle when
not in use.Driving characteristics and
towing tips
Before attaching a trailer, lubricatethe coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce
snaking movements.
For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than
1000 kg a speed of 80 km/h must not
be exceeded; the use of a stabiliser is
recommended.
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 3 252.
184Driving and operatingTrailer towingTrailer loadsThe 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 loads apply 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
3 238.
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.Petrol and diesel engines
The maximum permissible vertical
coupling load (55 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
trailers. The vertical coupling load
should never fall below 25 kg.Engine B14XEL LPG / D14XEL LPG
The maximum permissible vertical
coupling load (45 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
trailers. The vertical coupling load
should never fall below 25 kg.Rear axle loadPetrol and diesel engines
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) for passenger vehicles
may be exceeded by 70 kg for the 5-
door vehicle and 60 kg for the 3-door
vehicle, the gross vehicle weight
rating by 55 kg.Engine B14XEL LPG / D14XEL LPG
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) for passenger vehicles
may be exceeded by 70 kg for the 5-
door vehicle and 70 kg for the 3-door
vehicle and the gross vehicle weight
rating by 45 kg.Delivery van
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) for passenger vehicles
may be exceeded by 60 kg and the
gross vehicle weight rating by 55 kg.
Driving and operating185General
If the permitted rear axle load is
exceeded a maximum speed of
100 km/h applies. If lower national
maximum speeds are specified for
trailer operation, they must be
complied with.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Stowage of coupling ball bar
The coupling ball bar is stowed in a
bag in the spare wheel well and
secured to the lashing eyes in the
load compartment.
When inserting, fit protective cap over rotary knob with key.
Fitting the coupling ball bar
Disengage and fold down the socket. Remove the sealing plug from the
opening for the coupling ball bar and
stow it.
Checking the tensioning of the
coupling ball bar
● The rotary knob rests on the
coupling ball bar.
● Green marking on the rotary knob is not visible.
● Locking pin at the top of the coupling ball bar is set inwards.
● The key is in the lock.
Driving and operating187Eye for break-away stopping cable
Attach breakaway stopping cable to
eye.
Check that the coupling ball bar is correctly installed
● Green marking on rotary knob is visible.
● There must be no gap between the rotary knob and the coupling
ball bar.
● The coupling ball bar must be firmly engaged in the opening.
● The coupling ball bar must be locked and the key removed.
9Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
Dismounting the coupling ball bar
Insert the key in the lock and unlock
the coupling ball bar.
Push the rotary knob onto the
coupling ball bar and rotate right while pressed down until it engages. Pull
out the ball bar downwards.
Insert sealing plug in opening for
coupling ball bar. Fold away socket.
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 system is working keep
steering wheel as still as possible.
Trailer stability assist is a function of
the Electronic Stability Control 3 152.
