Safety FirstOperating instructionsTips and MaintenanceTe c h n i c a l D a t a Gross combination weight
The gross combination weight is the actual weight of the laden vehicle plus
the actual weight of the laden trailer . If the maximum permissible trailer
weight is to be utilized, the weight of the vehicle may have to be reduced.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving.
Tyre pressure
Set tyre pressure to the maximum permitted pressure shown on the sticker on
the inside of the tank flap. Set the tyre pressure of the trailer tyres in accord-
ance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
Headlight adjustment
If towing a trailer the dipped light may dazzle other drivers. Use the headlight
range control to lower the cone of light. If you do not have headlight range
control, have the headlights adjusted by a qualified dealership.
WARNING
•Never transport people in a trailer. This could result in fatal accidents.
•To avoid dazzling other drivers, adjust the dipped beam according to
the load. If not, an accident may occur.
•If using 225/45 R 17 94 W tyres for 7J x 17 wheels it is not permitted to
tow a trailer.
Note
•Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.
•Find out whether special regulations apply to towing a trailer in your
country.
Ball coupling of towing bracket
The removable ball coupling of the towing bracket is stored
with the tools on board behind the right-hand side trim of the

Checking and refilling levels 218
The coolant additive G 12+ (dyed purple) may be mixed with G 12 (dyed red)
and also with G 11.
WARNING
Any work carried out in the engine compartment or on the engine must be
carried out cautiously.
•When working in the engine compartment, always observe the safety
warnings Ÿpage 209
•When the engine is warm or hot, the cooling system is pressurised! Do
not unscrew the cap on the expansion tank when the engine is hot. This is
a burn injury risk.
Caution
•When mixed with other additives the colour of G 12 will change to brown.
If this occurs you should have the coolant changed immediately. Failure to do
so will result in engine damage!
•If a lot of coolant has been lost, wait for the engine to cool down before
putting in cold coolant. This avoids damaging the engine. Large coolant
losses are an indication of leaks in the cooling system. See a specialised
workshop immediately and have the cooling system checked. Otherwise,
there is a risk of engine damage.
Washer fluid and windscreen wiper blades
Topping up washer fluid Y
The water for cleaning the windscreen should always be
mixed with washer fluid.
The windscreen washer and the headlight washing system are supplied with
fluid from the windscreen washer fluid container in the engine compartment.
The reservoir is located on the right-hand side of the engine compartment.
Plain water is not enough to clean the windscreen and headlights. We recom-
mend that you always add a product to the windscreen washer fluid.
Approved windscreen cleaning products exist on the market with high deter-
gent and anti-freeze properties, these may be added all-year-round. Please
follow the dilution instructions on the packaging.

Colour coding of fusesWARNING
Never “repair” damaged fuses and never replace them with higher rating
fuses. This could cause fires.
Note
•If a newly inserted fuse blows after a short time, you must have the elec-
trical system checked by a qualified dealership as soon as possible.
•If you replace a fuse with a stronger fuse, you could cause damage to
another location in the electrical system.
Fuse table
The table shows the fuse locations for the most important consumers. The
right-hand columns contain the insert location, the figures in brackets indi-
cate the Ampere rating for the fuse. One single consumer could have more
than one fuse.Several consumers could run over one single fuse.
The fuse box has space for replacement fuses.
There are other fuses in the vehicle. These should be changed by a qualified
dealership.
