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.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,

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.

When towing
Distribution of loads
F Distribute  the   load   in   the   trailer   so   that   the h
eaviest   items   are   as   close   as   possible   to t

he   axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
Air
  density   decreases   with   altitude,   thus  
r

educing   engine   per formance.   Above  
1 0

00 metres,   the   maximum   towed   load   must  
b

e   reduced   by   10 %   for   every   1 000   metres   of  
al

titude.
Side wind
F Take   into   account   the   increased   sensitivity  t
o   side   wind.
For
  more   information   on   Weights
, refer
to   the   corresponding   section.
The   rear   parking   sensors   will   be  
d

eactivated   automatically   to   avoid   the  
a

udible   signal   if   a   genuine   CITROËN  
t

owbar   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   coolant  
t

emperature. F
 
I
f   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,   the   use   of  
e

ngine   braking   is   recommended.
Ty r e s
F Check  the   tyre   pressures   of   the   towing  v
ehicle   and   of   the   trailer,   observing   the  
re

commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n   the   trailer   and   the   headlamp   beam  
h

eight   of   your   vehicle.
For
  more   information   on   Adjusting the
headlamp beam height , refer to the
corresponding

Audio and Telematics
The table below gives answers to the most frequently asked questions on your audio system.
QUESTIONANSWERSOLUTION
With the engine off, the audio system switches off after a few minutes of use.
When the engine is switched off, the audio system operating time depends on the state of charge of the battery. The switch-off is normal: the audio equipment 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.
The message "the audio system is overheated" appears on the display.
In order to protect the installation if the surrounding temperature is too high, the audio system switches to an automatic thermal protection mode leading to a reduction in volume or CD play stopping.
Switch the audio system off for a few minutes to allow the system to cool.
Frequently asked questions
QUESTIONANSWERSOLUTION
There is a difference in sound quality between the different audio sources (radio, CD...).
For optimum sound quality, the audio settings (Volume, Bass, Treble, Ambience and Loudness) can be adapted to the different sound sources, which may result in audible differences when changing source (radio, CD...).
Check that the audio settings (Volume, Bass, Treble, Ambience and Loudness) are adapted to the sources listened to. It is advisable to set the audio functions (Bass, Treble, Front-Rear Balance and Left-Right Balance) to the middle position, select the musical ambience "None" and set the loudness correction to the "Active" position in CD mode or to the "Inactive" position in radio mode.
