brake
 
and
 
increase
 
the

  distance   from   other   vehicles.
Driving on flooded roads
We strongly advise  against  driving  on  flooded
 roads,  as  this  could  cause  seri -
ous
 
damage
 
to
 
the
 
engine
 
or
 
gearbox,
 
as

 
well
 
as
 
to
 
the

Do

 
not
 
park
 
or
 
run
 
the
 
engine when

stationary in areas where
inflammable substances  and  ma -terials (dry grass,  dead  leaves...) might
 come  into  contact  with  the hot

does

 
not

 
exceed

 
15

 
cm,

 
taking

TOWING A TRAILER
We recommend  the  use  of  genu -
ine  CITROËN  towbars  and  their  
harnesses

 
that
 
have
 
been
 
tested
 
and

 
approved
 
from
 
the
 
design
 
stage

 
of
 
your
 
vehicle,
 
and
 
that
 
the

 
fitting
 
of
 
the
 
towbar
 
is
 
en
-
trusted
 
to
 
a
 
CITROËN
 
dealer
 
or
 
a

  qualified   workshop.
If
 
the
 
towbar
 
is
 
not
 
fitted
 
by
 
a
 
CITROËN

 
dealer
,  
it
 
must
 
still
 
be

 
fitted
 
in
 
accordance
 
with
 
the
 
vehicle

 
manufacturer's
 
instruc
-
tions.
Your
 
vehicle
 
is
 
primarily
 
designed
 
for
 
transporting

 
people
 
and
 
luggage,
 
but
 
it
 
may

 
also   be   used   for   towing   a   trailer.
Driving  
with
 
a
 
trailer
 
places
 
greater
 
de
-
mands
 
on
 
the
 
towing
 
vehicle
 
and
 
the
 
driver

  must   take   particular   care.
Driving advice
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
 
maximum
 
permitted

  without   exceeding   it.
Air
 
density
 
decreases
 
with
 
altitude,
 
thus
 
reducing

 
engine
 
performance.
 
Above
 
1 

000  
metres,
 
the
 
maximum
 
towed
 
load
 
must

 
be
 
reduced
 
by
 
10 
%  
for
 
every
 
1 000

  metres   of   altitude.
Side wind
F
 
T
ake  
into
 
account
 
the
 
increased
 
sensitivity

  to   side   wind.
Cooling
Towing
 
a
 
trailer
 
on
 
a
 
slope
 
increases
 
the

  temperature   of   the   coolant.
As
 
the
 
fan
 
is
 
electrically
 
controlled,
 
its
 
cooling

 
capacity
 
is
 
not
 
dependent
 
on
 
the

  engine   speed.
F
 
T
o  
lower
 
the
 
engine
 
speed,
 
reduce
 
your

  speed. The
 
maximum
 
towed
 
load
 
on
 
a
 
long
 
in
-
cline  depends  on  the  gradient  and  the  ambient
  temperature.
In  all  cases,  keep  a  check  on  the  
 
coolant

  temperature.
F
 
If
 
the
 
warning
 
lamp
 
and
 
the
 
ST

OP  
warning
 
lamp
 
come
 
on,

 
stop
 
the
 
vehicle
 
and
 
switch

 
of
f  
the
 
engine
 
as
 
soon

  as   possible.
Braking
Towing
 
a
 
trailer
 
increases
 
the
 
braking
 
distance.
T

o  
avoid
 
overheating
 
of
 
the
 
brakes
 
on
 
a
 
long

 
mountain
 
type
 
of
 
descent,
 
the
 
use
 
of

  engine   braking   is   recommended.
Tyres
F
 
Check
 
the
 
tyre
 
pressures
 
of
 
the
 

towing

 
vehicle
 
and
 
of
 
the
 
trailer
,  
observing

 
the
 
recommended
 
pres
-
sures.
Lighting
F
 
Check
 
the
 
electrical
 
lighting
 
and
 
sig
-
nalling
  on   the   trailer.
Refer
 
to
 
the
 
"T
echnical  
data"
 
section
 
for
 
details

 
of
 
the
 
weights
 
and
 
towed
 
loads
 
which

  apply   to   your   vehicle.
The
 
rear
 
parking
 
sensors
 
will
 
be

 
deactivated

FREqUENTLY ASKED q UESTIONS
qUESTION ANSWER SOLUTION
With
 
the   engine   off,   the  
audio

 
system   switches  
of

f
 
after   a   few   minutes  
of

 
use. When
  the   engine   is   switched   off,   the   audio   system   operating   time  
depends

  on   the   battery   charge.
The
  switch-off   is   normal:   the   audio   system   switches   to   economy   mode  
and

  switches   off   to   prevent   discharging   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   of   the   volume   or   stopping   of   the   playing   of   the   CD.Switch
  the   audio   system   off   for   a   few   minutes   to  
allow

  the   system   to   cool.
