d

river:
-
 
d
irect   arrival   in   the   passenger  
c

ompartment   (air   intake),
-

When

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  
c

onditioning   results   in   a   discharge  
o

f   water   under   the   vehicle   which   is  
p

er 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

A few driving recommendations
Observe the driving regulations at all times and remain   vigilant   whatever   the   traffic   conditions.
Pay
  close   attention   to   the   traffic   and   keep   your  
h

ands   on   the   wheel   so   that   you   are   ready   to  
r

eact   at   any   time   to   any   eventuality.
On
  a   long   journey,   a   break   every   two   hours   is  
s

trongly
 re
commended.
In
  difficult   weather,   drive   smoothly,   anticipate  
t

he   need   to   brake   and   increase   the   distance  
f

rom   other   vehicles.
Driving on flooded roads
We strongly advise against driving on flooded roads,   as   this   could   cause   serious   damage  
t

o   the   engine   or   gearbox,   as   well   as   to   the  
e

lectrical   systems   of   your   vehicle.
Important!If you are obliged to drive through water:
-  
c
heck   that   the   depth   of   water   does   not  
e

xceed   15   cm,   taking   account   of   waves  
t

hat   might   be   generated   by   other   users,
-
 
d
eactivate   the   Stop   &   Start   system,
-
 
d
rive   as   slowly   as   possible   without  
s

talling.   In   all   cases,   do   not   exceed   6   mph  
(

10 km/h),
-
 
d
o   not   stop   and   do   not   switch   off   the  
e

ngine. Never
  drive   with   the   parking   brake  
a

pplied   -   Risk   of   overheating   and  
d

amage   to   the   braking   system!
Do
  not   park   or   run   the   engine   when  
s

tationary   in   areas   where   inflammable  
s

ubstances   and   materials   (dry   grass,  
d

ead   leaves...)   might   come   into   contact  
w

ith   the   hot   exhaust   system   -   Risk   of  
f

ire!
Never
  leave   a   vehicle   unsupervised  
w

ith   the   engine   running.   If   you   have  
t

o   leave   your   vehicle   with   the   engine  
r

unning,   apply   the   parking   brake  
a

nd   put   the   gearbox   into   neutral   or  
p

osition

N or P,
  depending   on   the   type  
o

f   gearbox.
On
  leaving   the   flooded   road,   as   soon   as  
c

ircumstances   allow,   make   several   light   brake  
a

pplications   to   dry   the   brake   discs   and   pads.
If
  in   doubt   on   the   state   of   your   vehicle,   contact  
a

  CITROËN   dealer   or   a   qualified   workshop.
