Warning and indicator lamps
Visual indicators which  inform  the  driver  of  the  occurrence  of  a  malfunction  (warn -
ing  lamp)  or  of  the  operation  of  a  system  (operation  or  deactivation  indicator  lamp).
When the ignition is switched on
Certain
 
warning
 
lamps
 
come
 
on
 
for
 
a
 
few
 
seconds
 
when
 
the
 
ignition
 
is
 
switched
 
on.
When

  the   engine   is   started,   these   warning   lamps   should   go   off.
If
 
they
 
remain
 
on,
 
before
 
moving

refer
 
to
 
the
 
information
 
on
 
the
 
warning
 
lamp
 
in

  question.
Associated warnings
The
 
illu
mination,  
fixed
 
or
 
flashing,
 
of
 
certain
 
warning
 
lamps
 
may
 
be
 
accompanied
 
by

  an   audible   signal   and   the   display   of   a   message.
Warning lamps
When the  engine  is  running  or  the  vehicle  is  being  driven,  the  illumination  of  one  of  the  fol -
lowing  warning  lamps  indicates  a  malfunction  which  requires  action  on  the  part  of  the  driver .
The
  warning   comes   on   in   the   instrument   panel.
If your vehicle has a screen, a
warning lamp  coming  on  is  al -
ways
 
accompanied
 
by
 
the
 
dis
-
play
 
of
 
an
 
additional
 
message,
 
to

 
assist
 
you
 
in
 
identifying
 
the
 
problem.
If

 
you
 
encounter
 
any
 
problems,
 
do

 
not
 
hesitate
 
to
 
contact
 
a
 
CITROËN

Brake fluid level
Changing the fluid
Refer 
to
 
the
 
manufacturer's
 
service
 
schedule

 
for
 
details
 
of
 
the
 
interval
 
for
 
this

  operation.
Fluid specification
The
 
brake
 
fluid
 
must
 
conform
 
to
 
the
 
manufacturer's

  recommendations.
Power steering fluid level
The power steering  fluid  level should
 be  close  to  the  "MAX" mark.

 
With
 
the
 
engine
 
cold,
 
un
-
screw
 
the
 
cap
 
to
 
check
 
the
 
level.
Coolant level
The coolant level  should  be  close
 to  the  "MAX"  mark  but  
should

  never   exceed   it.
When
 
the
 
engine
 
is
 
warm,
 
the
 
temperature

 
of
 
the
 
coolant
 
is
 
regulated
 
by

 
the
 
fan.
In
 
addition,
 
as
 
the
 
cooling
 
system
 
is
 
pressurised,

 
wait
 
at
 
least
 
one
 
hour
 
after
 
switching

 
of
f  
the
 
engine
 
before
 
carrying
 
out

 
any
  work.
To
 
avoid
 
any
 
risk
 
of
 
scalding,
 
unscrew
 
the cap by two turns to allow the pres

-
sure
 
to

 
drop.
 
When
 
the
 
pressure
 
has
 
dropped,

 
remove
 
the
 
cap
 
and
 
top
 
up
 
the

 
level.
Fluid specification
The
 
coolant
 
must
 
conform
 
to
 
the
 
manu
-
facturer's
  recommendations.
The cooling fan may start after
switching off the engine: take
care with articles and clothing
that might be caught by the
fan blades.
The
 brake
 fluid
 level
 should
 be
 close
 to
 the
 "MAX"
 mark.
 If
 it
 is
 not,
 
check
 
the
 
brake
 
pad
 
wear.
Topping up the engine oil level
Refer
 
to

 
the

 
"Petrol

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

sensors
 
will
