Driving and operating141
1000 kg a speed of 50 mph 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 3 217.
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 loads apply 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 plate
3 197.
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 (vehicles with 1.2
engine: 45 kg, other engines: 55 kg)
is specified on the towing equipment
identification plate and in the vehicledocuments. 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 load 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 45 kg and the
gross vehicle weight rating by 50 kg
(on vehicles with 1.2 engine and
specific rear axle application: 30 kg).
For vans the permitted rear axle load
may be exceeded by 25 kg. The
permitted total load may be exceeded
by the following amounts with the
engines specified below:A10XEP=30 kgA12XEL, A12XER=25 kgA13DTR=40 kgA13DTE, A13DTC=35 kg
Trailer operation is not permitted for
vans with tyre size 215/45 R 17.

Accessories and vehicle
modifications
We recommend using genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
The following must be carried out if
the vehicle is to be stored for several
months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve rubber seals.
■ Fill up fuel tank completely.
■ Change engine oil.
■ Drain washer fluid reservoir.
■ Check coolant antifreeze and corrosion protection.
■ Adjust tyre pressure to the value specified for full load.
■ Park vehicle in dry, well ventilated place. Engage first or reverse gear
or set selector lever to P. Prevent
the vehicle from rolling.
■ Do not apply parking brake.

150Vehicle careBrakesA squealing noise indicates that the
brake lining is at its minimum
thickness. Continued driving is
possible but have the brake lining
replaced as soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and the MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.
Brake and clutch fluid 3 195.
Vehicle battery Vehicles without stop-start system
will be equipped with a lead acid
battery. Vehicles with stop-start
system will be equipped with an
AGM battery which is not a lead acid
battery.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
4 weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
