D R I V I N G

The parking sensors system cannot,
in any circumstances, replace the
need for vigilance and responsibility
on the part of the driver.

VISUAL AND AUDIBLE
FRONT AND/OR REAR
PARKING SENSORS

System consisting of proximity sen-

sors, installed in the front and/or rear
bumper.
It detects any obstacle (person, vehi-
cle, tree, barrier...) located in front of
or behind the vehicle, however, it will
not be able to detect obstacles locat-
ed immediately below the bumper.
An  object,  such  as a stake,  a road-
works cone or any other similar ob-
ject  may  be  detected  at  the  start  of
the  manoeuvre  but  may  no  longer
be detected when the vehicle moves
nearer to it.

The parking sensors are switched
on :
-

by engaging reverse gear,

at a speed below 6 mph (10 km/h)
in forward gear.

This is accompanied by an audible
signal and/or displaying of the vehi-
cle on the multifunction screen.
The proximity information is indicat-

ed by:
-

an audible signal which be-
comes more rapid as the vehicle
approaches the obstacle,

a  diagram  on  the  multifunction
display,  with  blocks  which  move
closer to the vehicle.

The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the ve-
hicle and the obstacle is less than

approximately thirty centimetres,

the audible signal becomes con-
tinuous and/or the "Danger" symbol
appears, depending on the multi-
function screen version.

The  parking  sensors  are   switched
off :
   -   when you exit reverse gear,
  -

when the speed is higher than
6 mph (10 km/h) in forward gear,

when the vehicle has been station-
ary for more than three seconds in
forward gear.

Deactivation
 Press button A , the warning lamp

comes on, the system is fully de-
activated.

The  system  will  be  deactivated  au-
tomatically  when  a  trailer  is  being
towed  or  when  a  bicycle  carrier  is

ﬁ tted (vehicle ﬁ tted with a towbar

or bicycle carrier recommended by
CITROËN).

157

D R I V I N G

Reactivation

  In  bad  weather  or  in  winter,  ensure
that  the  sensors  are  not  covered
with  mud,  ice  or  snow.  When  re-
verse  gear  is  engaged,  an  audible
signal (long beep) indicates that the
sensors may be dirty.
When  the  speed  of  the  vehicle  is
below about 6 mph (10 km/h), some
sources  of  noise  (motorcycle,  lorry,
pneumatic  drill,  ...)  may  trigger  the
audible parking sensor signals.

 Press button A again, the warn-

ing lamp switches off, the system
is reactivated.

"HYDRACTIVE III +"
ELECTRONIC SUSPENSION

The suspension automatically and
instantly adjusts to different driving

styles and to the proﬁ le of the road,

providing the best compromise be-
tween occupant comfort and vehicle
road holding.
The system alternates between soft

and ﬁ rm suspension settings, maxi-

mising comfort at the same time as
constantly ensuring the highest level
of  safety.  It  also  automatically  cor-
rects  ride  height,  according  to  the
vehicle load and driving conditions.
In addition, the "Hydractive III +" sys-
tem  allows  you  to  choose  between
two modes of suspension.
A  change  of  suspension  mode  can
be  made  either  when  the  vehicle  is
moving or when stationary, by press-
ing button  A .

Display on the instrument
panel

The suspension mode selected is
displayed on the instrument panel
screen.

Normal mode

This mode favours soft

damping for maximum com-

fort.
If the speed authorised for a

particular position is exceed-

ed, the vehicle reverts automatically
to the normal road position.

SPORT mode

This mode favours dynamic
driving.
  The  warning  lamp  on  but-
ton  A   comes  on  in  addition
to  the  message  on  the  in-
strument panel screen.

SPORT mode is retained when you
switch off the engine.

Vehicle positions

  Maximum height
Changing  a  wheel  (not  possible  if
speed > 6mph (10km/h)).

Intermediate position
For increased ground clearance (not
possible if speed > 25 mph (40 km/h)).
For use on difﬁ cult roads when tra-

velling at reduced speed, as well as
on car park ramps.

  Position  changes  may  only  be
made when the engine is running.
The  adjustable  ground  clearance
meets  all  types  of  situation.  Apart

from a few speciﬁ c situations, the

vehicle should be in the Normal po-
sition.
 Press once on one of the adjust-

ment controls.

The change in position is indicated
by a message on the instrument
panel screen.

Normal position
If the speed authorised for a particu-

lar position is exceeded, the vehicle

reverts automatically to the normal
position.

Minimum height
To facilitate loading or unloading the
vehicle.
For workshop inspections.
Not to be used in normal driving (not
possible if speed > 6mph (10km/h)).

D R I V I N G

Position not authorised

The instrument panel screen tempo-
rarily displays a message indicating
that this position is not authorised.
The  vehicle  remains  in  the  autho-
rised  position  and  the  instrument
panel  screen  indicates  this  position
to you.

Automatic variation of ground clea-
rance
- If your speed exceeds 70 mph

(approx. 110 km/h), on a good

road  surface,  ground  clearance
is  lowered.  The  vehicle  returns
to  its  normal  position  if  the  road
surface  deteriorates  or  if  your
speed is lower than 55 mph (ap-

prox. 90 km/h).

At  low  or  medium  speed,  if  the
road  surface  is  poor,  ground
clearance  is  increased.  The  ve-
hicle  returns  to  its  normal  posi-
tion as soon as conditions allow.

On switching off the ignition, the
ground clearance is reduced to
the parking position

   For your safety if you are operat-
ing  underneath  the  vehicle,  you
must  support  the  vehicle  with
axle stands.

C H E C K S

Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signiﬁ cantly, have the

corresponding system checked by a
CITROËN dealer.

Oil level

Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.

  Oil speciﬁ cation
The oil must correspond to your en-
gine  and  conform  to  the  manufac-
turer's recommendations.

Brake fluid level

  Fluid change
Refer  to  the  Maintenance  and
Warranty Guide for details of the in-
terval for this operation.
This ﬂ uid must be changed regular-

ly. Fluid which has been used exces-
sively may cause a loss of braking

efﬁ ciency.

Fluid speciﬁ cation

The brake ﬂ uid must conform to the

manufacturer's

recommendations

and meet the DOT4 standard.

The  reading  will  only  be
correct  if  the  vehicle  is  on
level ground and the engine
has  been  off  for  more  than

15 minutes.

The check is carried out either when
the ignition is switched on using the
oil  level  indicator  on  the  instrument
panel, or using the dipstick.
Check this level also between each
scheduled  service  and  before  long
journeys.
Take  care  when  doing  anything  un-
der the bonnet, as some parts of the
engine can be extremely hot (risk of
burns).

The brake ﬂ uid level should

be close to the "MAX" mark.
If it is not, check the brake
pad wear.

In  order  to  maintain  the  reli-
ability of the engine and emis-
sion  control  system,  the  use
of additives in the engine oil is
prohibited.

Power steering fluid or power
steering and suspension
fluid level

This ﬂ uid must be topped up

by a CITROËN dealer.

Dipstick
There are 2 marks on the
dipstick:
-

A = max; never exceed
this level,

B = min; top up the

level via the oil ﬁ ller

cap,  using  the  type
of  oil  suited  to  your
engine.

169

C H E C K S

Screenwash and headlamp
wash fluid

Fluid speciﬁ cation
For optimum cleaning and to avoid

freezing, this ﬂ uid must not be

topped up or replaced with water.
Reservoir capacities:
- screenwash: approximately 3.5 li-

tres,

screenwash and headlamp wash:

approximately 6.15 litres.

Diesel additive level
(Diesel engine with particle
emission filter)

A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.

Topping up
This additive must be topped up by
a CITROËN dealer without delay.

Used products

Avoid prolonged contact of

used oil or ﬂ uids with the

skin.

Most of these ﬂ uids are harmful to

health or indeed very corrosive.

Do not discard used oil or ﬂ u-

ids into sewers or onto the
ground.

Take used oil to a CITROËN deal-
er (France) or an authorised waste
disposal site.

In the case of vehicles ﬁ tted

with headlamp washers, the

minimum level of this ﬂ uid is

indicated by an audible sig-

nal and a message on the multifunc-
tion screen.
Top up the level when you stop the
vehicle.

Coolant level

  Coolant change
The  coolant  does  not  have  to  be
changed.

  Fluid speciﬁ cation
The  coolant  must  conform  to  the
manufacturer's recommendations.

The coolant level should be
close to the "MAX" mark but
should never exceed it.

When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.

On vehicles which are ﬁ tted with

a particle emission ﬁ lter, the fan

may operate after the vehicle has
been switched off, even if the en-
gine is cold.
In addition, as the cooling system is
pressurised,  wait  at  least  one  hour
after switching off the engine before
carrying out any work.
To  avoid  any  risk  of  scalding,  un-
screw  the  cap  by  two  turns  to  al-
low the pressure to drop. When the
pressure  has  dropped,  remove  the
cap and top up the level.

CHECKS

Unless  otherwise  indicated,  check
these  components  in  accordance
with the Maintenance and Warranty
Guide  and  according  to  your  en-
gine.
Otherwise, have them checked by a
CITROËN dealer.

Battery

The  battery  does  not  re-
quire any maintenance.
However,  check  that  the
terminals are clean and cor-
rectly  tightened,  particularly
in summer and winter.

When carrying out work on the bat-
tery,  refer  to  the  "Practical  infor-
mation"  section  for  details  of  the
precautions  to  be  taken  before  dis-
connecting the battery and following
its reconnection.

Air filter and passenger compartment filter

Refer  to  the  Maintenance
and  Warranty  Guide  for
details  of  the  replacement
intervals  for  these  compo-
nents.

Depending on the environment (e.g.
dusty  atmosphere)  and  the  use  of
the vehicle (e.g. city driving),  replace
them  twice  as  often  if  necessary
(refer to the "Engines" section).
A  clogged  passenger  compartment

ﬁ lter may have an adverse effect on

the performance of the air condition-
ing system and generate undesir-
able odours.

Oil filter

Replace the oil ﬁ lter each

time the engine oil is
changed.

Particle filter system (Diesel)

Complementary to the catalytic

converter, this ﬁ lter makes an ac-

tive  contribution  to  the  preservation
of  air  quality  by  the  retaining  of  the
unburnt  pollutant  particles.  Black
exhaust  fumes  are  thus  no  longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice  water  vapour  being  emitted  from
the  exhaust  when  accelerating.  This
is of no consequence to the running of
the vehicle or to the environment.

If  there  is  risk  of  clogging,  a  mes-
sage  appears  on  the  instrument
panel  display,  accompanied  by  an
audible  signal  and  lighting  of  the
service warning lamp.
This alert tells you that the particle

ﬁ lter is starting to ﬁ ll up (in condi-

tions of urban driving of excep-
tionally long duration: low speeds,

trafﬁ c jams etc.).

To regenerate the ﬁ lter, it is advised

to drive as soon as possible, when

trafﬁ c conditions permit, at a speed

of 40 mph (around 60 km/h) or

more for at least ﬁ ve minutes (until

the alert message disappears).
If this alert persists, consult a
CITROËN dealer.

Refer  to  the  Maintenance  and
Warranty  Guide  for  details  of  the  re-
placement interval for this component.

The presence of this label, in par-
ticular with the Stop & Start system,

indicates the use of a speciﬁ c 12 V

lead-acid battery with special tech-

nology and speciﬁ cation, for which

the  involvement  of  a  CITROËN
dealer is required when replacing or
disconnecting the battery.
Failure  to  observe  this  recommen-
dation  may  cause  premature  wear
of the battery.

171

C H E C K S

Brake pads

Brake  wear  depends  on
the  style  of  driving,  par-
ticularly  in  the  case  of  ve-
hicles  used  in  town,  over
short  distances.  It  may  be

necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a

drop in the brake ﬂ uid level indicates

that the brake pads are worn.

Manual gearbox

The gearbox does not re-
quire any maintenance (no
oil change).

Automatic gearbox

The gearbox does not re-
quire any maintenance (no
oil change).

Brake disc wear

For  information  relating  to
checking  the  brake  disc
wear,  contact  a  CITROËN
dealer.

Parking brake

If  a  loss  of  effectiveness
of  this  system  is  noticed,
the parking brake must be
checked,  even  between
two services.

This system must be checked by a
CITROËN dealer.

Only use products recom-
mended by CITROËN or
products of equivalent quality

and speciﬁ cations.

Do not use a dry cloth with an abra-
sive product for the maintenance of
aluminium parts; use a sponge and
soapy water.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-

fers very speciﬁ c products.
To  avoid  damaging  the  electrical
units,  the  use  of  a  high  pressure
washer in the engine compartment
is strictly  prohibited .

Refer to the Maintenance and
Warranty Guide for the details of the
level checking interval for this com-
ponent.
