SNOW CHAINS
In wintry conditions,  snow  chains  im -
prove traction as well as the behaviour
of
  the   vehicle   when   braking. Advice on installation
F
 
If
 
you
 
have
 
to
 
fit
 
the
 
chains
 
during
 
a

 
journey
,  
stop
 
the
 
vehicle
 
on
 
a
 
flat
 
surface

  on   the   side   of   the   road.
F
 
Apply
 
the
 
parking
 
brake
 
and
 
posi
-
tion
 
any
 
wheel
 
chocks
 
to
 
prevent
 
movement

  of   your   vehicle.
F
 
Fit
 
the
 
chains
 
following
 
the
 
instruc
-
tions
  provided   by   the   manufacturer.
F
 
Move
 
of
f  
gently
 
and
 
drive
 
for
 
a
 
few

 
moments,
 
without
 
exceeding
 
30 mph

  (50   km/h).
F
 
Stop
 
your
 
vehicle
 
and
 
check
 
that
 
the

 
snow
 
chains
 
are
 
correctly
 
tight
-
ened.
The
 
snow
 
chains
 
must
 
be
 
fitted
 
only

 
to
 
the
 
front
 
wheels.
 
They
 
must

 
never
 
be
 
fitted
 
to
 
"space-
saver"

  type   spare   wheels.
Take
 
account
 
of
 
the
 
legislation
 
in
 
force in your country on the use
of

 
snow
 
chains
 
and
 
the
 
maxi
-
mum
  running   speed   authorised.Avoid
 
driving
 
with
 
snow
 
chains
 
on

 
roads
 
that
 
have
 
been
 
cleared
 
of

 
snow
,  
to
 
avoid
 
damaging
 
your
 
vehicle's

 
tyres
 
and
 
the
 
road
 
sur
-
face.
 
If
 
your
 
vehicle
 
is
 
fitted
 
with
 
alloy

 
wheels,
 
check
 
that
 
no
 
part
 
of

 
the
 
chain
 
or
 
its
 
fixings
 
is
 
in
 
contact

  with   the   wheel   rim.

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

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

sures.
Lighting
F
 
Check

PETROL WEIGHTS AND TOWED LOADS ( IN KG )
The GTW and  towed  load  values  indicated  are  valid  up  to  a  maximum  altitude  of  1  000  metres;  the  towed  load  mentioned  must

* The  kerb   weight   is   equal   to   the   unladen   weight    +   driver   (75   kg).
**   
The
 
weight
 
of
 
the
 
braked
 
trailer
 
can
 
be
 
increased,
 
within
 
the
 
GTW
 
limit,
 
if
 
the
 
GVW
 
of
 
the
 
towing
 
vehicle
 
is
 
reduced
 
by
 
an

  equal   amount.   Warning:   towing   using   a   lightly   loaded   towing   vehicle   may   have   an   adverse   effect   on   its   road   holding.
The
 
GTW
 
and
 
towed
 
load
 
values
 
indicated
 
are
 
valid
 
up
 
to
 
a
 
maximum
 
altitude
 
of
 
1
 
000
 
metres;
 
the
 
towed
 
load
 
mentioned
 
must

  be   reduced   by   10   %   for   each   additional   1   000   metres   of   altitude.
When
  towing,   the   maximum   authorised   speed   is   reduced   (comply   with   the   legislation   in   force   in   your   country).
High
 
ambient
 
temperatures
 
may
 
result
 
in
 
a
 
reduction
 
in
 
the
 
performance
 
of
 
the
 
vehicle
 
to
 
protect
 
the
 
engine;
 
if
 
the
 
ambient
 
temperature

  is   above   37   °C,   limit   the   towed   load.
