Trailer weight
The trai
ler weights and drawbar loads ap-
proved are selected in intensive trials accord-
ing to precisely defined criteria. The ap-
proved trailer weights are valid for vehicles in
the EU for maximum speeds of 80 km/h (50
mph) (in certain circumstances up to 100
km/h (62 mph)). The figures may be different
in other countries. All data in the official vehi-
cle documentation takes precedence over
these data at all times

Dr
a
wbar loads
The maximum permitted drawbar load on the
ball joint of the towing bracket must not ex-
ceed 80 kg.
In the interest of road safety, we recommend
that you always tow approaching the maxi-
mum drawbar load. The response of the trail-
er on the road will be poor, if the drawbar
load is too small.
If the maximum permissible drawbar load
cannot be met (e.g. with small, empty and
light-weight single axle trailers or tandem
axle trailers with a wheelbase of less than 1
metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar
load.
WARNING
●
For s
afety reasons, you should not drive at
speeds above 80 km/h (50 mph) when towing
a trailer. This also applies in countries where
higher speeds are permitted.
●
Never exceed the maximum trailer weights
or the drawbar load. If the permissible axle
load or the permissible total weight is excee-
ded, the driving characteristics of the vehicle
may change, leading to accidents, injuries
and damage to the vehicle.

Tyre pressures
The s
tic
ker with the tyre pressure values can
be found on the inside of the fuel tank flap.
The tyre pressure values given there are for
cold tyres. The slightly raised pressures of
warm tyres must not be reduced.
›››
The pressure for win
t
er tyres is 0.2 bar
(2.9 psi / 20 kPa) higher than that of summer
tyres.
Snow chains
Snow chains may be fitted only to the front
wheels, and only for the following tyres:
215/60 R16 Chains with links of maximum 15 mm
215/55 R17 Chains with links of maximum 15 mm
215/50 R18 Chains with links of maximum 15 mm
Other dimensions do not allow chains
Wheel bolts
Aft
er the wheels have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque
wrench ›››
. The tightening torque for steel
and allo
y wheels is 140 Nm.
WARNING
●
Check
the tyre pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
●
If the tightening torque of the wheel bolts
is too low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged.
Note
We recommend that you ask your Technical
Serv
ice for information about appropriate
wheel, tyre and snow chain size.
