Under-inflation detection
The system monitors the pressures in the four t
yres,   once   the   vehicle   is   moving.
It
  compares   the   information   given   by   the   four  
w

heel speed sensors with reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed .
The
  system   triggers   an   alert   as   soon   as   it  
d

etects a drop in the inflation pressure of one
or
  more   tyres. The
  under-inflation   detection   system  
d

oes   not   replace   the   need   for   vigilance  
o

n   the   part   of   the   driver.
This
  system   does   not   avoid   the   need   to  
c

heck   the   tyre   pressures   (including   the  
s

pare   wheel)   every   month   as   well   as  
b

efore   a   long   journey.
Driving
  with   under-inflated   tyres   impairs  
r

oad   holding,   extends   braking   distances  
a

nd   causes   premature   tyre   wear,  
par

ticularly under arduous condition
(high
  loading,   high   speed,   long   journey).
System
  which   automatically   checks   the   pressures   of   the   tyres   while   driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure
  label.
For
  more   information   on   the  
i

dentification   markings,   refer   to   the  
c

orresponding
 s
ection.
Tyre
  pressures   should   be   checked  
w

hen the tyres are "cold" (vehicle
stopped
  for   1   hour   or   after   a   journey   of  
l

ess   than   6   miles   (10   km)   at   moderate  
s

peeds).
Other wise
  (when   hot),   add   0.3   bar   to  
t

he   pressures   shown   on   the   label.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.

Fuel tank
Capacity of the tank:
- Pe trol:   approximately   50   litres.
-
 
D
iesel:   approximately   45   or   50   litres   (depending   on   version).
Low fuel levelRefuelling
When the low fuel level is reached,
this
  warning   lamp   in   the   instrument  
p

anel   comes   on,   accompanied   by  
a

n   audible   warning,   a   message   and  
t

he   last   bar   of   the   fuel   gauge   flashes  
i

n   red.
To
  refuel   in   complete   safety:
F

Y

F
 
O
pen   the   filler   flap.
A label on the inside of the fuel filler flap
reminds
  you   of   the   type   of   fuel   to   use,  
d

epending   on   your   engine   type.
Additions
  of   fuel   must   be   of   at   least   5   litres   to  
b

e   registered   by   the   fuel   gauge.
When
 
it
 
first   comes   on,   about 5 litres of fuel
remain
 
in
 
the   tank.
Until sufficient fuel has been added, this
warning
 
lamp   appears   every   time   the   ignition  
i

s
 
switched   on,   accompanied   by   an   audible  
w

arning
 
and   a   message.   This   audible   warning  
a

nd
 
message   are   repeated   with   increasing  
f

requency
  as   the   fuel   level   drops   towards   "0 ".
Refuel
 
as
  soon   as   possible   to   avoid   running  
o

ut. Opening
  the   filler   cap   may   result   in   an   inrush   of  
a

ir.   This   is   entirely   normal   and   results   from   the  
s

ealing   of   the   fuel   system.
With Stop & Start, never refuel with the
system
  in   STOP   mode;   you   must   switch  
o

ff   the   ignition   with   the   key.

When not towing a trailer, remove the quickly-detachable   tow   ball   before  
d

riving.
Towing a trailer
We recommend the use of genuine C ITROËN towbars and their harnesses
that have been tested and approved
from
  the   design   stage   of   your   vehicle,  
a

nd   that   the   fitting   of   the   towbar   is  
e

ntrusted to a CITROËN dealer or a
qualified
 w

orkshop.
If the towbar is not fitted by a
CITROËN
  dealer,   it   must   still   be  
f

itted in accordance with the vehicle
manufacturer's
 i

nstructions.
Your
 
vehicle   is   primarily   designed   for  
t

ransporting   people   and   luggage,   but   it   may  
a

lso
 
be   used   for   towing   a   trailer. Driving   with   a   trailer   places   greater  
d

emands   on   the   towing   vehicle   and   the  
d

river   must   take   particular   care.
For   more   advice   on   driving   when  
t

owing,   refer   to   the   corresponding  
s
