If it is not possible to tow the vehicle in  
the normal way, or if it has to be towed fur-  
ther than 50 km (30 miles), it must be  
transported on a special car transporter or  
trailer.

Certain restrictions must be observed when  
towing your vehicle.

tor lever will be locked. Before the vehicle  
can be recovered/manoeuvred you must  
manually release the selector lever  
››› page 41.  
The vehicle can be towed with a tow bar or  
tow rope in the normal way, with all four  
wheels on the ground. When doing so, please  
note the following points:  
Only replace fuses when the cause of the  
problem has been solved. If a newly inserted  
fuse blows after a short time, you must have  
the electrical system checked by a special-  
ised workshop as soon as possible.  
●
Make sure the selector lever is in the N  
position.  
The vehicle must not be towed faster than  
50 km/h (30 mph).  
●
●
The vehicle must not be towed further than  
WARNING  
50 km (30 miles). Reason: when the engine  
is not running, the gearbox oil pump does not  
work and the gearbox is not adequately lubri-  
cated for higher speeds or longer distances.  
The high voltages in the electrical system  
can give serious electrical shocks, causing  
burns and even death!  
●
Never touch the electrical wiring of the  
ignition system.  
If the vehicle has to be towed with a break-  
down truck, it must only be suspended at the  
front wheels. Reason: the drive shafts are lo-  
cated on the front wheels. If the car is towed  
with the rear wheels lifted off the road (I.e.  
travelling backwards), the drive shafts also  
turn backwards. The planetary gears in the  
automatic gearbox then turn at such high  
speeds that the gearbox will be severely  
damaged in a short time.  
●
Take care not to cause short circuits in  
the electrical system.  
WARNING  
Using unsuitable fuses, repairing fuses or  
bridging a current circuit without fuses can  
cause a fire and serious injury.  
●
Never use a fuse with a higher value. Only  
replace fuses with a fuse of the same
