• The removable ball coupling of the towing bracket* may be
stored in the right-hand rear of the boot.
•Additional mirrors are required if the traffic behind the trailer is
not visible with the exterior mirrors fitted as standard. Both exterior
mirrors must be attached to brackets in such a way that a sufficient
field of vision to the rear is guaranteed at all times.
•The permitted trailer weight must not be exceeded under any
circumstances
⇒chapter “Technical Data”.
•When using a trailer on mountain routes you must bear in mind
that the tow loads given in the “Technical data” chapter are onlyapplicable for slopes of 10% to 12%. If you do not use the full tow
load you may drive up steeper slopes.
•The given trailer weights are only applicable for altitudes up
to 1000 m above sea level. As the engine output drops due to
the decreasing air density, the climbing ability must also be
reduced by 10% for each further 1000 m.
•Where possible make full use of the maximum permissible
drawbar weight on the ball of the towing bracket but do not exceed
it
⇒chapter “Technical Data”.
•While observing the permissible trailer and drawbar weight,
distribute the load in the trailer so that heavyobjects are as near
as possible to the axle. The objects must also be secured so that
they cannot slip about.
•The tyre pressures on the towing vehicle must be adjusted for full
load conditions, and also check the pressures on the trailer.
•Headlight settings should be checked, with the trailer attached,
before beginning the journey and adjusted as necessary.
On vehicles with headlight beam control it is only necessary to turn
the knurled disc on the dash board in the appropriate direction.

To obtain the best possible handling of vehicle and trailer, the
following should be noted:
• Try to avoid driving with an unladen vehicle and a loaded trailer.
If this cannot be avoided, only drive slowly to allow for the
unfavourable weight distribution.

• As driving stability of vehicle and trailer decreaseswhen the
speed increases do not drive at the maximum permissible top
speed in unfavourable road, weather or wind conditions –
particularly when going downhill.
In any case the speed must be reduced as soon as the trailer
shows the slightest sign of snaking. On no account try to stop the
snaking by accelerating.

• Always brake in good time. If the trailer has an overrun brake,
apply the brakes gently at first then firmly. This will avoid the
jerking caused by the trailer wheels locking.
Change down before going down a steep hill so thatthe engine
can act as a brake.
• When a long climb in a low gear with extremely high engine revs
must be negotiated at exceptionally high ambient temperatures
the coolant temperature gauge must be observed. When the gauge
needle moves to the right end of the scale, the road speed must be
reduced immediately.
• The cooling effect of the radiator fan cannot be increased by
changing down, because the speed of the fan is not dependent on
the engine speed. One should therefore not change down even
when towing a trailer as long as the engine can cope without the
vehicle speed dropping too much.

• The trailer and drawbar load figures on the data plate of the
towing bracket are for test certification only. The correct figuresfor
the vehicle, which may be lower than the above figures, are given
in the vehicle documents and in this manual.
• When using the towing device the car’s empty weight is reduced,
and as a result its effective load is decreased.
• Observe all statutory requirements regarding the use of a
trailer.

Coolant specifications
The cooling system is filled at the factory with a permanent coolant
which is not changed. The coolant consists of water and a 40%
concentration of our coolant additive
G G1
12
2+
+(glycol-based anti-
freeze with anti-corrosion additives). This mixture not only gives
the necessary frost protection down to –25 °C but also protects the
alloy parts in the cooling system against corrosion. In addition it
prevents scaling and significantly raises the boiling point of the
coolant.
The concentration of the coolant therefore must not be reduced in
the summer or in warm countries, by topping up with plain water.

• Only our G12+ (purple colour) should be used as an antifreeze additive.
Observe the notice on the container. The cooling liquid may be purchased in
Technical Services.
• The antifreeze additive G12+ can be mixed with other additives (G11 and
G12).
• The additive G12 (red colour) should never be mixed with G11.
K
Checking coolant level
The level can only be checked properly when the engine is not
running.
The coolant level must be between the
m ma
ax
xand m
mi
in
nmarks on the
expansion tank when engine is cold and can be slightly above the
m ma
ax
xmark when it is warm.K
Coolant losses
Coolant loss normally indicates leaks in the system. In this case
the cooling system should be checked by a Technical Service
Center without delay. It is not sufficient merely to add coolant.
In a sealed system losses can only occur if the boiling point of the
coolant is exceeded as a result of overheating, and coolant is
forced out of the system.
K
Topping up coolant
Switch engine off and let it cool down. Then cover expansion tank
cap with a cloth and turn cap carefully anti-clockwise and remove.
No other coolant may be used if
G G1
12
2+
+is not available. In this
case only water can be used and the correct mixture concentration
must be restored with the specified coolant additive (see previous
page) as soon as possible.
