Before each use
Check that the towball is correctly fitted by verifying the following points:
-  t he   towball   is   correctly   locked   in   place   (position   A),
-
 
t
he   security   key   lock   is   on   and   the   key   removed;   the   locking   wheel   can   no   longer   be  
ope

rated,
-
 
t
he   towball   must   no   longer   move   at   all   in   its   carrier;   try   to   shake   it   by   hand.
During use
Never unlock the device when a trailer or load carrier is fitted to the towball.
N ever   exceed   the   maximum   authorised   weight   for   the   vehicle   plus   trailer   (Gross   Train  
W

eight   -   GTW).
After use
For journeys made without a trailer or load carrier, the trailer harness socket must be folded away,   the   towball   removed   and    the   blanking   plug   inserted   in   the   carrier.   This   measure  
a

pplies   particularly   if   the   towball   could   hinder   visibility   of   the   number   plate   or   lighting.
