PARKING SPACE SENSORS
System which measures  the  parking  space
available between two vehicles
or
 
obstacles.
 
It
 
measures
 
the
 
size
 
of
 
the
 
space

  and   gives   you   information   on:
-
 the

 
possibility
 
of
 
fitting

 the

 
level
 
of

of
 
the
 
manoeuvre to

  be   performed.

You
 
must
 
refuel
 
as

as
 
possible
 
to
 
avoid

Low fuel level Refuelling
Additions of
 fuel  must  be  of  at  least  
5  litres  to  be  registered  by  the  fuel  
gauge.
Opening

 
the

 is  held  in  a  spe -

of

 
the

It
