Rear suspension
Metal suspension
This equipment adopts long movement
limiters which make it possible to guarantee
stable behaviour both when loaded and
when empty. No action on your part is
required except to ensure that maintenance
is carried out and that the authorised loads
are complied with. irrespective of the weight of the load, within
the limit of the authorised values. On board,
the increasing or lightening of the load on
the vehicle’s platform is detected by two
height sensors. When all of the doors are
closed, the sensors trigger the automatic
compensation and determine the optimum
height of the sill for the vehicle’s driving
conditions.
Deactivation of the automatic correction
The control which permits deactivation of the
automatic control is located on the right-
hand side, at the rear of the vehicle.
REAR SUSPENSION
You must deactivate the automatic
correction manually in the following
situations:
- when working underneath the vehicle,
- when changing a wheel,
- when the vehicle is being transported by lorry, train, ferry, boat, ...
Two types of suspension are offered.
Rear suspension with pneumatic
compensation
If fitted on your vehicle, this type of
suspension regulates the variations in the
height of the rear platform of your vehicle
1. Automatic correction

2. Manual correction
1 - Automatic correction of the height of the rear sill
The pneumatic suspension automatically
regulates the variations in the height of the
rear platform of your vehicle. A red warning light on your
instrument panel fl ashes if the
height is not at its optimum level and
requires correction, drive slowly until
this warning light is switched off.
The automatic compensation is temporarily
inactive:
- if a door/the tailgate is open,
- when braking or when stopped at a red light (brake pedal pressed). With the vehicle stationary:
- press and hold,
- release the control.
Deactivation is confirmed by
the diode which is lit. It remains lit for
approximately 30 seconds.
Return to automatic correction
With the vehicle stationary:
- press and hold,
- release the control.
Return to automatic correction is confirmed
by the diode which is switched off.
According to the configurations, a bleep may
be heard during these operations.

2 - Manual correction of the height of the rear sill First use
To initialise the function, press the control
for approximately 2 seconds.
Return to the optimum sill height
Press the control up or down twice in
succession, the opposite of the position of
the load sill.
Carry out these operations with the vehicle
still stationary and:
- with the front and side doors closed,
- with the handbrake applied,
- do not leave your foot on the brake
pedal.
If your vehicle is fitted with this adjustment,
the control is located on the right-hand side
at the rear of the vehicle.
This manual adjustment permits "lowering"
or "raising" of the height of the sill of the rear
platform to facilitate operations in a parking
area.
This adjustment of the height of the sill is
restricted by a lower limit and an upper limit. Lower: downwards adjustment
of the platform sill
Press the control downwards
continuously.
Release the button to stop the movement,
"3 bleeps" indicate that you have reached
the maximum limit, the movement stops
automatically.
Raise: upwards adjustment of
the platform sill
Press the control upwards
continuously.
Release the button to stop the movement,
"3 bleeps" indicate that you have reached
the maximum limit, the movement stops
automatically. Operating faults
If the load sill is not adjusted when the
control is pressed, "3 bleeps" indicate a
malfunction for the following reasons:
- foot on the brake pedal with the key in
the ignition,
- excessive use of the manual correction,
- low battery charge,
- failure of the system.
If the audible signal persists, contact a
CITROËN dealer.

Rear suspension
Deactivation of the manual correction Good practice
When stationary and with the ignition key
removed, excessive use of the system
consumes battery charge. Parking for a long duration
Avoid parking for a long duration on ground
which could present a potential obstacle as
your vehicle could lower.
Following a long period out of use, the
height of the platform may change due to the
automatic compensation on unlocking or on
opening one of your vehicle’s doors.
With the vehicle stationary:
- press and hold,
- release the control.
Deactivation is confirmed by
the diode which is lit. It remains lit for
approximately 30 seconds.
Return to manual correction
According to the configurations, a bleep may
be heard during these operations.
You must deactivate the manual
correction in the following situations:
- when working underneath the vehicle,
- when changing a wheel,
- when the vehicle is being transported by lorry, train, ferry, boat, ... Warning light
Driving with the height of the rear platform:
- too low, risks damaging the technical
components underneath the vehicle,
- too high, risks unstable driving.
With the vehicle stationary:
- press and hold,
- release the control.
Return to manual correction is
confirmed by the diode which is switched off. Refer to the "Instruments and controls"
section of chapter 2.
If you start and the warning light flashes,
to switch it off:

towards the pavement and pull the handbrake.
There is no advantage in engaging a gear after
parking the vehicle, particularly if the vehicle is
loaded. HAZARD WARNING LIGHTS
Press this button, the direction indicators fl ash.
They can operate with the ignition off.
The hazard warning lights should only be
used in dangerous situations, when stopping
in an emergency or when driving in unusual
conditions.
DRIVING SAFETY
Applying
Pull the handbrake to immobilise your
vehicle.
Check that the handbrake is applied firmly
before leaving the vehicle. If the handbrake is still on or has
not been released properly, this

Parking assistance
SAFETY
4
The audible and/or visual rear parking
assistance consists of four proximity
sensors, installed in the rear bumper. The
sensors detect any obstacle which enters
the field: person, vehicle, tree, fence, behind
the vehicle during the manoeuvre.
Certain objects detected at the beginning of
the manoeuvre will no longer be detected
at the end of the manoeuvre due to the
blind spots between and below the sensors.
Examples: stake, roadworks cone or
pavement post. Engage reverse gear
An audible signal confirms the activation of
the system by engaging reverse gear.
The proximity information is indicated by an
audible signal which becomes more rapid as
the vehicle approaches the obstacle. When
the distance between the rear of the vehicle
and the obstacle is less than approximately
thirty centimetres, the audible signal
becomes continuous.
Stop the assistance
Change to neutral.
REAR PARKING ASSISTANCE
Activation/Deactivation
You can activate or deactivate the
system by pressing this button.
The activation or deactivation of
the system is stored when the
vehicle stops.
Operating fault
In the event of an operating fault, when
reverse gear is engaged the diode on
the button comes on, accompanied by
an audible signal and a message on the
display. Consult a CITROËN dealer.
Good practice
In bad weather or in winter, ensure that the
sensors are not covered with mud, ice or
snow.
The system will be deactivated automatically
if a trailer is being towed or if a bicycle
carrier is fitted (vehicle fitted with a
towbar or bicycle carrier recommended by
CITROËN).
The parking assistance cannot, in any
circumstances, take the place of the
vigilance and responsibility of the driver.
Display on the screen
You are advised to deactivate the system if
your vehicle is fitted with a rear ladder or if
you are transporting a load which exceeds
the length of the vehicle.

ABS

HORN
Press the centre of the steering wheel.
ANTI-LOCK BRAKING SYSTEM (ABS - EBFD)
The ABS and EBFD (electronic brake force
distribution) systems improve the stability
and manoeuvrability of your vehicle on
braking, in particular on poor or slippery
surfaces.
The ABS prevents locking of the wheels,
the EBFD provides control of the braking
pressure wheel by wheel. Good practice
The anti-lock braking system comes into
operation automatically when there is a risk
of wheel lock. It does not reduce the braking
distance.
On very slippery surfaces (ice, oil, etc...)
the ABS may increase the braking distance.
When braking in an emergency, do not
hesitate to press the brake pedal firmly,
without releasing the pressure, even on a
slippery surface, you will then be able to
continue to manoeuvre the vehicle to avoid
an obstacle.
Normal operation of the ABS may be felt by
slight vibration of the brake pedal.
When changing wheels (tyres and rims),
ensure that these are recommended by
CITROËN.
If this warning light comes on,
together with the brake and STOP
warning lights, accompanied by
an audible signal and a message
on the display, it indicates a malfunction of
the electronic brake force distribution which
could result in a loss of control of the vehicle
on braking.

Stop immediately.
EMERGENCY BRAKING ASSISTANCE SYSTEM (EBA)
In an emergency, this system enables the
optimum braking pressure to be reached
more quickly, press the pedal firmly without
releasing it.
It is triggered by the speed at which the brake
pedal is activated. This alters the resistance
of the brake pedal under your foot.
If this warning light comes on,
accompanied by an audible signal
and a message on the display,
it indicates a malfunction of the
ABS which could result in a loss of control of
the vehicle on braking. In both cases, contact a CITROËN dealer.
To prolong the operation of the emergency
braking assistance system: keep your foot
on the brake pedal.

ESP

Driving safety
SAFETY
4
TRACTION CONTROL (ASR) AND DYNAMIC STABILITY CONTROL (ESP)
These systems are linked and complement
the ABS.
The ASR system is very useful for
maintaining optimum drive and avoiding
losses of control of the vehicle on
acceleration.
The system optimises drive to prevent the
wheels skidding, by acting on the brakes of
the drive wheels and on the engine. It also
allows the directional stability of the vehicle
to be improved on acceleration. acts on the engine and the brake of one
or more wheels, in order to put the vehicle
back on course.
Disarming the ASR/ESP systems
In certain exceptional conditions (starting
the vehicle when stuck in mud or snow, or
on loose ground...), it could prove useful to
disarm the ASR and ESP systems to make
the wheels spin and regain grip.
- Press the button, located on the centre
console.
- The indicator light comes on: the ASR and ESP systems no longer act. Operating check
Good practice
The ASR/ESP systems offer increased
safety during normal driving, but should not
incite the driver to take risks or to drive at
high speed.
The operation of these systems is ensured
if the recommendations of the manufacturer
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the fitting and repair
procedures within the CITROËN network are
observed.
After an impact, have these systems
checked by a CITROËN dealer.
Use the ESP to hold your course without
attempting to countersteer.
If there is a variation between the trajectory
followed by the vehicle and that required
by the driver, the ESP system automatically Operation of the ASR and ESP
systems
The luminous diode flashes when
the ASR or ESP is triggered.
They engage again:
- automatically above 30 mph (50 km/h),
- manually by pressing the button again. When a malfunction of the
systems occurs, the indicator light
comes on, accompanied by an
audible signal and a message on
the display.
Contact a CITROËN dealer to have the
system checked.
The warning light may also come on if the
tyres are under-inflated. Check the pressure
of each tyre.
