Air intake
The air circulating in the passenger compartment   is   filtered   and   originates   either  
f

rom   the   outside   via   the   grille   located   at   the  
b

on
 
a
 
steep
 
gradient
 
in
 
high
 
temperatures,
 
switching
 
off
 
the

ir
 
conditioning
 
increases
 
the
 
available
 
engine
 
power
 
and
 
so
 
improves
 
the
 
towing
 
ability. The condensation created by the air
conditioning
  results   in   a   discharge  
o

f water under the vehicle which is
per fectly   normal.
If   after   an   extended   stop   in   sunshine,  
t

he   interior   temperature   is   very  
h

igh,   first   ventilate   the   passenger  
c

ompartment   for   a   few   moments.
Put   the   air   flow   control   at   a   setting   high
