Starting and driving
Towing equipment
Towbars
The towball must be cleaned and greased
regularly. If a towball hitch with vibration
damper is used, it is not necessary to grease
the towball.
If the car is equipped with a detachable
towbar, the towball mounting instructions
must be followed carefully, see page 137.
NOTE!
Always take off the towball section
after use. Keep it in the cargo area.
Trailer cable
An adapter is required if the car’s towbar has
13 pin electrics and the trailer has 7 pin
electrics. Use an adapter cable approved by
Volvo. Make sure the cable does not drag on
the ground.
WARNING!
Be sure to attach the trailer’s safety cable
to the correct place.
WARNING!
If the car is fitted with a Volvo detachable
towbar: follow the assembly instructions
for the towball section carefully. The
towball section must be locked with the
key before setting off. Check that the
indicator window shows green.
