General information
The coupling ball bar is kept in a bag,
fastened with a strap and is stowed
below the floor cover in the load
compartment.
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.
Control indicator á illuminates in the
instrument cluster when a trailer is
connected to the vehicle 3 91.
Driving characteristics and towing tips
In the case of trailers with brakes,
attach the break-away stopping cable
to the eye - not to the coupling ball
bar.
If no eye is available, loop cable
around coupling ball bar. Ensure
cable is crossed under the verticalcoupling socket to ensure the trailer
nose cannot drop to the ground if it
becomes separated from the trailer
hitch. Do not allow the cable to drag
along the ground and always allow
enough slack to permit full turning.
Follow the instructions supplied with
the towing equipment.
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
friction-type stabiliser is strongly
recommended.
Do not drive faster than 80 km/h, even in countries where higher speeds are
permitted. When driving uphill, do not drive faster than 30 km/h in 1st gear,or 50 km/h in 2nd gear.
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.
Driving and operating153Adjust tyre pressure to the value
specified for full load 3 212.
Trailer towing Trailer loadsThe 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.
When the trailer load is being
checked, therefore, only the trailer
wheels - and not the jockey wheel -
must be standing on the weighing
apparatus.
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 sea
level. 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 plate3 205.
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 (80 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.When measuring the vertical coupling
load, ensure the drawbar of the
loaded trailer is at the same height as it will be when the trailer is coupled
with the towing vehicle loaded. This is
particularly important for trailers with
tandem axle.
Rear axle load
When the trailer is coupled and the
towing vehicle is fully loaded
(including all occupants), the
permissible rear axle load (see
identification plate or vehicle
documents) must not be exceeded.
National regulations regarding
maximum speeds for vehicles towing a trailer must be observed.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
154Driving and operatingTowing equipment with
detachable coupling ball bar
The coupling ball bar is kept in a bag,
fastened with a strap and is stowed
below the floor cover in the load
compartment.
Fitting the coupling ball bar
Remove sealing plug from the hole for
the coupling ball bar and stow it in the load compartment.
Confirm that the colour marking on
the lever is red.
Inserting the coupling ball bar
Insert the coupling ball bar into the
coupling housing and push firmly
downwards until the coupling ball bar
audibly engages. If it does not
engage, repeat fitting procedure.
Do not swing the coupling ball bar to
the left or right, or upwards and
downwards, to avoid disrupting
correct fitting.
Lock coupling ball bar by turning the
supplied key in the lock cylinder of the coupling ball bar. Remove key.
Driving and operating155Check that the coupling ball bar is
correctly attached:
● Green marking must be visible on
lever.
● Coupling ball bar must be seated
firmly in coupling housing.
Coupling ball bar must be locked and key must be removed.9 Warning
Towing a trailer is permitted only
when the coupling ball bar is fitted correctly. If the coupling ball bar
cannot be properly attached, seek the assistance of a workshop.
Eye for break-away stopping cable
In the case of trailers with brakes,
attach the break-away stopping cable
to the eye - not to the coupling ball
bar.
Dismounting the coupling ball bar
Unlock coupling ball bar and remove
key. Push lever to the left, towards the
coupling ball bar and turn it
downwards. Pull coupling ball bar out of coupling housing.
Remove any rust or dirt from area
around the coupling housing and
coupling ball bar connection before
inserting sealing plug in the hole.
Place the coupling ball bar in the bag supplied, fasten it with the strap and
stow it below the floor cover in the
load compartment.
Do not use steam-jet cleaners or
other high-pressure cleaners to clean
the coupling ball bar.
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 (TSA) is a
function of the Electronic Stability
Control 3 145.

Spare wheel
Temporary spare wheel
Some vehicles are equipped with a tyre repair kit instead of a spare
wheel.
The temporary spare wheel is
designed for use on your vehicle only.
If mounting a spare wheel which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
Use of the temporary spare wheel
could affect driveability, particularly if
using winter tyres. Have the defective
tyre renewed as soon as possible and have the wheel balanced and fitted tothe vehicle.Caution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The temporary spare wheel is located in the load compartment below the
