h

ands on the wheel so that you are ready to

  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
the
  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,
-
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.
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.
Important!
Never drive with the parking brake applied   -   Risk   of   overheating   and  
d

amage   to   the   braking   system!
Risk
  of   fire!
As
  the   exhaust   system   of   your   vehicle  
i

s very hot, even several minutes after
switching
  off   the   engine,   do   not   park  
o

r   run   the   engine   over   areas   where  
in

flammable substances and materials
are
  present:   grass,   leaves,   etc...
Never leave a vehicle unsupervised
with
  the   engine   running.   If   you   have  
t

o   leave   your   vehicle   with   the   engine

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the
  axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
Air density decreases with altitude, thus
reducing
  engine   per formance.   Above  
1 0

00 metres,   the   maximum   towed   load   must  
b

e reduced by 10 % for every 1 000 metres of
altitude.
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
audible
  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
the
  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
height
  of   your   vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding
 s

ection.

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.
