152Driving and operatingconsumption and CO2 figures.
Furthermore, fuel consumption is dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
The coupling ball bar is kept in a bag,
fastened with a strap and is stowed
below the floor cover in the load
compartment.
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Control indicator á illuminates in the
instrument cluster when a trailer is
connected to the vehicle 3 91.
Driving characteristics and towing tips
In the case of trailers with brakes,
attach the break-away stopping cable
to the eye - not to the coupling ball
bar.
If no eye is available, loop cable
around coupling ball bar. Ensure
cable is crossed under the verticalcoupling socket to ensure the trailer
nose cannot drop to the ground if it
becomes separated from the trailer
hitch. Do not allow the cable to drag
along the ground and always allow
enough slack to permit full turning.
Follow the instructions supplied with
the towing equipment.
Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements. For trailers with
low driving stability, the use of a
friction-type stabiliser is strongly
recommended.
Do not drive faster than 80 km/h, even in countries where higher speeds are
permitted. When driving uphill, do not drive faster than 30 km/h in 1st gear,or 50 km/h in 2nd gear.
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.

If there is water in the diesel fuel filter, control indicator U illuminates in the
instrument cluster 3 90. Drain the
water immediately.
Diesel fuel system bleeding
If the fuel tank has been run dry, the
diesel fuel system must be bled.
Switch on the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of
40 seconds. If the engine will not start, wait at least 10 seconds before trying
again. If the engine fails to start, seek the assistance of a workshop.Wiper blade replacement

retaining clip and detach wiper blade.
Attach the wiper blade slightly angled
to the wiper arm and push until it
engages.
Lower wiper arm carefully.
Bulb replacement
