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).

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)).

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.

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.

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.

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 .
