166Driving and operatingDriving characteristics andtowing tips
Before attaching a trailer, lubricate the 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
1100 kg the use of a stabiliser is
strongly recommended when driving
above 50 mph.
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 3 234.Trailer towing
Trailer loads9 Warning
Vehicles with engine A13DTE:
Use of towing equipment is
permissible for attaching
compatible bicycle carriers only.
Do not use towing equipment for
trailer towing.
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 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 air becoming 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
3 223.
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 (75 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.

Vehicle care175the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.
Power steering fluid level normally
must not be checked. If an unusual
noise sounds during steering or the
power steering reacts conspicuous
seek the assistance of a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Brakes
In the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
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 fluid
9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.
