PARKING SPACE SENSORS
System which measures  the  parking  space
available between two vehicles
or
 
obstacles.
 
It
 
measures
 
the
 
size
 
of
 
the
 
space

  and   gives   you   information   on:
-
 the

 
possibility
 
of
 
fitting
 
into
 
a
 
free space,

 
depending
 
on
 
the
 
dimensions of

 
your
 
vehicle
 
and
 
the
 
distances needed

  for   manoeuvring,
-
 the

 
level
 
of
 
difficulty
 
of
 
the
 
manoeuvre to

  be   performed.
The
 
system
 
does
 
not
 
measure
 
spaces
 
which

 
are
 
clearly
 
much
 
smaller

at
 
a

Parking possible
Parking difficult
Parking not advised The
 function  deselects  itself  automati -
cally:

when
  you   engage   reverse   gear,

lateral
 
distance
 
between
 
your

the

If there is a fault, have the sys-

checked
 
by
 
a
 
CITROËN

  or   a   qualified   workshop.
The
 
system
 
remains
 
available
 
after
 
each

 
measurement
 
and
 
can
 
therefore
 
measure

  several   spaces   in   succession.
In poor or wintry weather, ensure that

PARKING SENSORS
This system  indicates  the  proximity of
an obstacle (person, vehicle, tree,
gate,  etc.)
 
which
 
comes
 
within
 
the
 
field of

 
detection
 
of
 
sensors
 
located
 
in
 
the bumper

.
Certain
 
types
 
of
 
obstacle
 
(stake,
 
road
-
works
 
cone,
 
etc.)
 
detected
 
initially
 
will
 
no

 
longer
 
be
 
detected
 
at
 
the
 
end
 
of
 
the
 
manoeuvre

 
due
 
to
 
the
 
presence
 
of
 
blind
 
spots.
This function cannot, in any cir

-
cumstances,
 
take
 
the
 
place
 
of
 
the

  vigilance   of   the   driver.The
 
system
 
is
 
switched
 
on
 
by
 
engaging
 
reverse

 
gear
.  
This
 
is
 
accompanied
 
by
 
an

  audible   signal.
The
 
system
 
is
 
switched
 
of
f  
when
 
you
 
come

  out   of   reverse   gear.
Rear parking sensors
Audible assistance
The 
proximity
 
information
 
is
 
given
 
by
 
an
 
intermittent

 
audible
 
signal,
 
the
 
frequen
-
cy of which increases as the vehicle ap-
proaches
  the   obstacle.
The
 
sound
 
emitted
 
by
 
the
 
speaker
 
(right
 
or

 
left)
 
indicates
 
the
 
side
 
on
 
which
 
the
 
obstacle

  is   located.
When
 
the
 
distance
 
between
 
the
 
vehicle
 
and

 
the
 
obstacle
 
becomes
 
less
 
than
 
approximately

 
thirty
 
centimetres,
 
the
 
audible

  signal   becomes   continuous.Visual assistance
This
 
supplements
 
the
 
audible
 
signal
 
by

 
displaying
 
bars
 
in
 
the
 
multifunction
 
screen

 
which
 
move
 
progressively
 
near
-
er
 
to
 
the
 
vehicle.
 
When
 
the
 
obstacle
 
is
 
near

,  
the
 
"Danger"
 
symbol
 
is
 
displayed
 
in

  the   screen.

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,

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 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

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
