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 height
correction and determine the optimum height
of the sill for the vehicle's driving conditions.
Deactivation of automatic height correction
The control which permits deactivation of
automatic regulation is located on the right-
hand side, at the rear of the vehicle.
REAR SUSPENSION
You must deactivate automatic height
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 available.
Rear suspension with pneumatic
height correction
If fi tted on your vehicle, this type of
suspension regulates the variations in the
height of the rear platform of your vehicle 1. Automatic height
correction
2. Manual height 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 lamp goes off.
The automatic height correction is
temporarily inactive:
- if a door / the tailgate is open,
- when braking or when stopped at a red traffic signal (brake pedal pressed). With the vehicle stationary:
- press and hold,
- release the control.
Return to automatic correction With the vehicle stationary: - press and hold,
- release the control.
According to the configurations, a beep may
be heard during these operations.

Rear suspension
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 parking brake 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 beeps" 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 beeps" indicate that you have reached
the maximum limit, the movement stops
automatically. Malfunctions
If the load sill is not adjusted when the
control is pressed, "3 beeps" indicate a
malfunction for the following reasons:
- foot on the brake pedal with the key in
the ignition,
- excessive use of the manual correction,

Deactivation of manual height correction Good practice
When stationary and with the ignition key
removed, excessive use of the system
consumes battery power. Long term parking
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 height correction on unlocking or
on opening one of your vehicle's doors.
With the vehicle stationary:
- press and hold,
- release the control.
Return to manual height correction
According to the configuration, a beep may
be heard during these operations. You must deactivate the manual height
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 lamp
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. Refer to the "Instruments and controls"
section of chapter 2.
If you start and the warning lamp flashes, to
switch it off:
- correct the position of the manual
control which is still at the lower or
upper limit,
- or drive slowly at above 6 mph (10 km/h), until height correction returns to automatic

PARKING BRAKE There is no advantage in engaging a gear after parking
the vehicle, particularly if the vehicle is loaded. HAZARD WARNING LAMPS
Press this button, the direction indicators
flash.
They can operate with the ignition off.
The hazard warning lamps should only be
used in dangerous situations, when stopping
in an emergency or when driving in unusual
conditions.
DRIVING SAFELY
Applying
Pull the parking brake lever up to immobilise
your vehicle.
Check that the parking brake is applied
firmly before leaving the vehicle.
If the parking brake is still on or has not been
released properly, this is indicated by this warning
lamp which comes on on the instrument panel.
Pull on the parking brake lever, only with
the vehicle stationary .
In the exceptional case of use of the parking
brake when the vehicle is moving, apply the
brake by pulling gently to avoid locking the
rear wheels (risk of skidding).
When parking on a slope, direct your wheels
towards the pavement and pull the parking
brake lever up.
Releasing
Pull the lever and press the button to lower
the parking brake lever.

Parking sensors
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 SENSORS
The audible and/or visual rear parking
sensor system 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.
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.
Malfunction
In the event of a malfunction, when reverse
gear is engaged the LED in the button
comes on, accompanied by an audible
signal and a message in the screen. Contact
a CITROËN dealer or a qualified workshop.
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 in 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.

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 lamp comes on,
together with the brake and STOP
warning lamps, accompanied by
an audible signal and a message
in the screen, it indicates a malfunction of
the electronic brake force distribution which
could result in a loss of control of the vehicle
on braking.
Stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or
a qualified workshop.
EMERGENCY BRAKING ASSISTANCE SYSTEM (EBA)
In an emergency, this system enables the
optimum braking pressure to be reached more
quickly, press the pedal fi rmly 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 lamp comes on,
accompanied by an audible signal
and a message in the screen,
it indicates a malfunction of the
ABS which could result in a loss of control of
the vehicle on braking. To prolong the operation of the emergency
braking assistance system: keep your foot
on the brake pedal.

ANTI-SLIP REGULATION (ASR) AND DYNAMIC STABILITY CONTROL (DSC)
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. If there is a variation between the trajectory
followed by the vehicle and that required by
the driver, the DSC system automatically
acts on the engine and the brake of one
or more wheels, in order to put the vehicle
back on course.
Deactivation
In certain exceptional conditions (starting
the vehicle when stuck in mud or snow, or
on loose ground...), it could prove useful
to deactivate the ASR and DSC systems to
make the wheels spin and regain grip.
Operating fault
Good practice
The ASR/DSC systems offer increased
safety during normal driving, but should not
encourage the driver to take risks or to drive
at high speed.
The operation of these systems is assured
only if the recommendations of the
manufacturer regarding the wheels (tyres
and rims), the braking components, the
electronic components and fitting and repair
procedures are observed.
After an impact, have these systems
checked by a CITROËN dealer or a qualified
workshop.
Use the DSC to hold your course without
attempting to countersteer.
Operation
The warning lamp flashes when
operation of the ASR or DSC 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 warning
lamp and the LED come on,
accompanied by an audible signal
and a message in the screen.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The warning lamp may also come on if the
tyres are under-inflated. Check the pressure
of each tyre.
- Press the button, located on the centre console.
- The LED comes on: the ASR and DSC systems no longer
operate.
