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
react
  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
stalling.
  In   all   cases,   do   not   exceed   6   mph  
(

10 km/h),
-

d
o not stop and do not switch off the
engine. 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!
ne

ver leave a vehicle unsupervised
with
  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.
