254
Protect your eyes and face before handling   the   battery.
All
  operations   on   the   battery   must   be  
c

arried   out   in   a   well   ventilated   area   and  
a

way   from   naked   flames   and   sources  
o

f   sparks,   so   as   to   avoid   the   risk   of  
e

xplosion   or   fire.
Do
  not   try   to   charge   a   frozen   battery;  
t

he   battery   must   first   be   thawed   out   to  
a

void   the   risk   of   explosion.   If   the   battery  
h

as   been   frozen,   before   charging   have  
i

t   checked   by   a   CITROËN   dealer   or   a  
q

ualified   workshop   who   will   check   that  
t

he   internal   components   have   not   been  
d

amaged   and   the   casing   is   not   cracked,  
w

hich   could   cause   a   leak   of   toxic   and  
c

orrosive   acid.
Do
  not   reverse   the   polarity   and   use   only  
a

  12   V   charger.
Do
  not   disconnect   the   terminals   while  
t

he   engine   is   running.
Do
  not   charge   the   batteries   without  
d

isconnecting   the   terminals   first.
Wash
  your   hands   after wards.do n ot push the vehicle to start the
engine   if   you   have   an   electronic   or  
a

utomatic   gearbox.
Some
 
functions
 
are
 
not
 
available
 
if
 
the
 
b

attery
 
is
 
not
 
sufficiently
 
charged.
It
 
is
 
advisable
 
to
 
disconnect
 
the
 
battery
 
if
 t

he
 
vehicle
 
is
 
to
 
be
 
left
 
unused
 
for
 
more
 t

han
 
one
 
month.
The batteries contain harmful substances s uch   as   sulphuric   acid   and   lead.   They m

ust   be   disposed   of   in   accordance
 w

ith   regulations   and   must   not,   in   any
 c

ircumstances,   be   discarded   with   household
 w

aste.
Take
  used   remote   control   batteries   and
 v

ehicle   batteries   to   a   special   collection   point.
Practical information

262
F If  the   warning   lamp   and   the  S
TOP  warning   lamp   come   on,  
s

top   the   vehicle   and   switch   off  
t

he   engine   as   soon   as   possible.
Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes   on   a   long  
m

ountain   type   of   descent,   the   use   of   engine  
b

raking   is   recommended.
Ty r e s
F Check   the   tyre   pressures   of   the  
towing   vehicle   and   of   the   trailer,   observing  
t

he
 re
commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n   the   trailer.
The
  rear   parking   sensors   will   be  
d

eactivated   automatically   if   a   genuine  
C

ITROËN   towbar   is   used.
Cooling
Towing a trailer on a slope increases the temperature   of   the   coolant.
As
  the   fan   is   electrically   controlled,   its   cooling  
c

apacity   is   not   dependent   on   the   engine   speed.
F
 
T
o   lower   the   engine   speed,   reduce   your  
s

peed.
The
  maximum   towed   load   on   a   long   incline  
d

epends   on   the   gradient   and   the   ambient  
t

emperature.
In
  all   cases,   keep   a   check   on   the   
c
oolant  
t

emperature.

Maintenance
In the event of a malfunction with the system, the "ECO OFF" switch warning lamp flashes, then comes on continuously. Have it checked by a CITROËN dealer or a qualified workshop.
Operating fault
This system requires a specific battery with a special specification and technology (reference numbers available from a CITROËN dealer or a qualified workshop). Fitting a battery not listed by CITROËN introduces the risk of malfunction of the system.
Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of START mode.
The Stop & Start system makes use of advanced technology. All work on this type of battery must be done only by a CITROËN dealer or a qualified
workshop.
In the event of a fault in STOP mode, the vehicle may stall. All of the instrument panel warning lamps come on. Depending on version, an alert message may also be displayed asking you to put the gear lever into position Nand put your foot on the brake pedal.
It is then necessary to switch off the ignition, then restart the engine using the key or the "START/STOP" button.
Reactivation
The system is reactivated automatically at every new start using the key or the "START/STOP" button.
Press the "ECO OFF" switch again. The system is active again; this is confirmed by the switch warning lamp going off and the display of a message.
Deactivation
At any time, press the "ECO OFF" switch to deactivate the system. This is confirmed by the switch warning lamp coming on accompanied by the display of a message.
If the system has been deactivated in STOP mode, the engine restarts immediately.

Running out of fuel (Diesel)
1.6 HDi engine 2.0 HDi engine
On vehicles fitted with HDi engines, the fuel system must be primed if you run out of fuel; refer to the corresponding engine compartment view.
If the tank on your vehicle is fitted with a misfuel prevention device, refer to the "Misfuel prevention (Diesel)" section.
BlueHDi engines
If the engine does not start first time, don't keep trying but start the procedure again from the beginning.
 Fill the fuel tank with at least five litres of diesel.  Open the bonnet.  If necessary, unclip the styling cover for access to the priming pump.  Squeeze and release the priming pump repeatedly until resistance is felt (there may be resistance at the first press).  Operate the starter until the engine starts (if the engine does not start at the first attempt, wait around 15 seconds before trying again).  If the engine does not start after a few attempts, operate the priming pump again
then start the engine.  Refit the styling cover and clip it in place.  Close the bonnet.
 Fill the fuel tank with at least five litres of Diesel.  Open the bonnet.  If necessary, unclip the style cover for access to the priming pump.  Slacken the bleed screw.  Squeeze and release the priming pump repeatedly until fuel appears in the transparent pipe.  Tighten the bleed screw.  Operate the starter until the engine starts (if the engine fails to start at the first attempt, wait around 15 seconds before trying again).
 If the engine fails to start after a few attempts, operate the priming pump again, then the starter.  Put the style cover back in position and clip it in place, ensuring that it has clipped c o r r e c t l y.  Close the bonnet.
 Fill the fuel tank with at least five litres of Diesel.  Switch on the ignition (without starting the engine).  Wait around 6 seconds and switch off the ignition.  Repeat the operation 10 times.  Operate the starter to run the engine.

QUESTIONANSWERSOLUTION
There is a difference in sound quality between the different audio sources.
For optimum sound quality, the audio settings for Volume, Bass, Treble, Equalizer and Loudness can be adapted to the different sound sources, which may result in audible differences when changing source.
Check that the audio settings for (Volume, Bass, Treble, Equalizer, Loudness) are adapted to the sources listened to. It is advisable to set the Audio functions (Bass, Treble, Fr-Re balance, Le-Ri balance) to the middle position, select the "Linear", musical ambience and set the loudness correction to the "Active" position in CD mode or to the "Inactive" position in radio mode.
With the engine off, the system switches off after a few minutes of use.
When the engine is switched off, the system's operating time depends on the state of charge of the battery. The switch-off is normal: the system switches to economy mode and switches off to prevent discharging of the vehicle's battery.
Start the vehicle's engine to increase the battery charge.
