Driving
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
Tyre pressures should be checked when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at
moderate speeds). Otherwise, add 0.3 bar to
the pressures shown on the label.
For more information on Identification
markings, including the tyre pressure label,
refer to the corresponding section.
The tyre pressure measurement unit can be configured with the MODE button: in
the "Tyre pressure measurement” menu, select
"psi/bar/kPa".
For more information on Vehicle configuration
(MODE), refer to the corresponding section.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
In the event of an anomaly noted on just one of
the tyres, depending on equipment, the symbol
or the message displayed identifies it.
► Reduce speed immediately, avoid excessive
steering movements and avoid sudden braking.
► Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected does not always cause visible bulging of the tyre.
Do not rely on just a visual check.
► Using a compressor, such as the one in
the temporary puncture repair kit, check the
pressures of the four tyres when cold.
► If it is not possible to make this check
immediately, drive carefully at reduced speed.
► In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the tyre/tyres concerned is/are reinflated, repaired or
replaced.
Malfunction
The flashing and then fixed illumination of this warning lamp, accompanied by the
illumination of the service warning lamp, and
depending on equipment, the display of a
message, indicates a fault with the system.
In this case, the tyre pressures are no longer
monitored.
This alert is also displayed if at least one wheel is not equipped with a sensor.
Contact a CITROËN dealer or a qualified
workshop to have the system checked or,
following a puncture, to have the original wheel,
equipped with a sensor, refitted.
Pneumatic suspension

If the vehicle is equipped with pneumatic
suspension, it is possible to change the height
of the rear sill, in order to facilitate loading or
unloading.




There is a normal sill level, as well as 3 higher
levels (from +1 to +3) and 3 lower levels (from
-1 to -3). Each level reached is displayed on the
instrument panel display screen.

Malfunction
If a fault occurs with the system, this
warning lamp comes on.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Driving with the suspension set too high
or too low poses risk of damaging
components under the body.
The height may be adjusted automatically to
take account of changes in temperature or
loading.
You must avoid using this control in the
following circumstances:
– when working underneath the vehicle,
– when changing a wheel,
– when the vehicle is being transported by
lorry, train, ferry, boat, etc.
To avoid damaging the vehicle or injuring
anyone, check that there is nothing or no
person that might be close to or come into
contact with the vehicle, before raising or
lowering the suspension.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climactic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
check the traffic, to assess the relative
distances and speeds of other vehicles and to
anticipate their movements before indicating
and changing lane.
The systems cannot exceed the limits of the
laws of physics.
Driving aids
You should hold the steering wheel
with both hands, always use the interior and
exterior rear view mirrors, always keep the
feet close to the pedals and take a break
every two hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during

76
Driving
simultaneously in the two dedicated areas of the
instrument panel.
If an additional road sign is detected, such
as a reduced speed limit for wet road sign, it
is displayed in an empty window below the
corresponding sign.
Additional signs are filtered as follows:
– Signs for snow or ice only appear if the
outside temperature is below 3°C.
– Signs for snow, rain or fog are only displayed
if the wipers are activated while the outside
temperature is below 3°C.
– Signs concerning heavy goods vehicles are
not displayed if they concern a vehicle weighing
less than 4 tonnes.
– Signs concerning farm equipment are not
displayed.
Signs such as no overtaking go out after about
40 seconds on the instrument panel.
Activation/Deactivation
This function can be set using the MODE button: in the “Traffic Sign” menu, select
“ON” or “OFF”.
For more information on Vehicle
configuration (MODE) , refer to the
corresponding section.
Operating limits
The system does not take account of reduced
speed limits, especially those imposed in the
following cases:
– Poor weather (rain, snow).
– Atmospheric pollution.
– Towing.
– Driving with a space-saver type spare wheel
or snow chains fitted.
– Driving with a non-standard suspension kit.
– Tyre repaired using the temporary puncture
repair kit.
– Young drivers.
The system may not display the speed limit if it
does not detect a speed limit sign within a preset
period and in the following situations:
– Road signs that are obstructed, non-standard,
damaged or bent.
– Obsolete or incorrect maps.
– Road incline causing the sign to be out of the
camera field of vision (on a slope, for example).
– Change in the vehicle load that causes the
camera to tilt significantly (system operation may
temporarily be suspended to enable camera
self-calibration).
Speed limiter
Refer to the General recommendations on the
use of driving and manoeuvring aids .
System which prevents the vehicle
from exceeding the speed
programmed by the driver. The speed is selected when the vehicle is
stationary with the engine running or while
driving with at least 2
nd gear engaged.
The minimum speed to be programmed is 19
mph (30 km/h).
The vehicle responds to the driver's foot
pressure on the accelerator until resistance is felt
in the pedal, which signifies that the vehicle has
reached the programmed speed.
However, depressing the pedal beyond this point
of resistance to the floor allows you to exceed
the programmed speed. To resume use of the
speed limiter, gradually release the pressure
on the accelerator pedal and return below the
programmed speed.


1. Selection of the speed limiter function
2. Activation / deactivation of the function
3. Programming a speed
The selection status of the function and the
programmed speed are visible in the instrument
panel display screen.
Selecting the function
► Turn ring 1 all the way down. The speed
limiter is selected, but is not yet active.


The display indicates OFF and the last
programmed speed.
Programming a speed
A speed can be programmed without activating
the speed limiter but with the engine running.
To memorise a speed higher than the previous
one:
► Move the control upwards (+).
A short press increases the setting by 1 mph
(km/h).
Pressing and holding increases the setting in
steps of 5 mph (km/h).
To memorise a speed lower than the previous
one:
► Move the control downwards (-).
A short press decreases the setting by 1 mph
(km/h).
Pressing and holding decreases the setting in
steps of 5 mph (km/h).
Activation/Deactivation
► Press button 2 to activate the speed limiter.

86
Driving
The message "Vehicle close" is displayed.Level 2 (red): visual and audible alert,
signalling that a collision is imminent.
The message "Brake! " is displayed.
Level 3: finally, in some cases, a haptic alert
in the form of micro-braking can be given,
confirming the risk of collision.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is never displayed
for a stationary obstacle or when the " Close"
trigger threshold has been selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
– The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle is detected.
– The vehicle's speed is between 3 mph and
53 mph (5 km/h and 85 km/h) when a moving
vehicle is detected.
This warning lamp flashes (for about 10 seconds) once the function is acting
on the vehicle's brakes.
With a manual gearbox, in the event of automatic
emergency braking until the vehicle comes to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by sharply turning the
steering wheel and/or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop, the
automatic braking is maintained for 1 to 2
seconds.
Malfunction
In the event of a system malfunction, this
warning lamp comes on on the instrument
panel, accompanied by an onscreen message
and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a CITROËN
dealer or a qualified workshop to have the
system checked.
Audible rear parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .


If fitted to your vehicle, the system consists of 4
proximity sensors installed in the rear bumper.
They detect any obstacle, e.g. person, vehicle,
tree, barrier, which is behind the vehicle while
manoeuvring.
Certain types of obstacle detected at the
beginning of the manoeuvre will no longer be
detected at the end of manoeuvre if they are
located in the blind spots between and under the
sensors. Examples: stake, roadworks cone or
pavement post.
The rear parking sensors may be associated
with the reversing camera.
Switching on
► Engage reverse gear with the gear lever.

replaced by a fuse; contact a CITROËN
dealer or a qualified workshop.
Compatibility of fuels
Diesel fuels conforming to the EN590, EN16734
and EN16709 standards and containing up to
7%, 10%, 20% and 30% fatty acid methyl ester
respectively. The use of B20 or B30 fuels, even
occasionally, imposes special maintenance
conditions referred to as "Arduous conditions".

Paraffinic Diesel fuel conforming to the EN15940
standard.
The use of any other type of (bio) fuel (vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited (risk
of damage to the engine and fuel system).
The only Diesel fuel additives authorised for use are those that meet the B715000
standard.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the
formation of paraffins in summer-type Diesel
fuels could prevent the engine from operating
correctly. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50 % full.
At temperatures below -15 °C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the
vehicle when braking.
The snow chains must be fitted only to the front wheels. They must never be
fitted to "space-saver" type spare wheels.
Observe the legislation in force in your
country on the use of snow chains and
the maximum authorised speed.
Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:
Original tyre size Maximum link size.
205/70 R15 16 mm
215/70 R15 12 mm
225/70 R15 16 mm
215/75 R16 12 mm
225/75 R16 16 mm
For more information on snow chains, contact a
CITROËN dealer or a qualified workshop.
Installation tips
► To fit the chains during a journey, stop the
vehicle on a flat surface on the side of the road.
► Apply the parking brake and position any
wheel chocks under the wheels to prevent
movement of the vehicle.
► Fit the chains following the instructions
provided by the manufacturer.
► Move off gently and drive for a few moments,
without exceeding 31 mph (50 km/h).
► Stop the vehicle and check that the snow
chains are correctly tightened.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry surface.
Avoid driving with snow chains on roads that have been cleared of snow to avoid
damaging the vehicle's tyres and the road
surface. If the vehicle is fitted with alloy

Roof-mounted carrying
systems


For safety reasons and to avoid damaging the
roof, it is imperative to use a carrying system
(roof bars or roof rack) approved for the vehicle.
Roof bars can only be fitted on H1 or H2 height
versions of vans, combis and minibuses. On
minibuses, check the presence of a roof air
conditioning unit.
The carrying device must be fixed to the
anchorage points on the roof of the vehicle: 6,
8 or 10, depending on the wheelbase of the
vehicle.
Observe the fitting instructions and the
conditions of use in the guide supplied with the
carrying device.
Maximum roof load, evenly distributed:
150 kg, for all versions, within the limits
of the gross vehicle weight (GVW).
Roofs cannot be equipped with a
carrying system on H3 height versions.
Strictly observe the legal provisions in
force concerning the maximum volume
measurements.
For more information on the Technical
data of the vehicle, and in particular on
the dimensions, refer to the corresponding
section.

AdBlue® (BlueHDi
engines)


To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel Particle Filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
Brake disc wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
Manual parking brake
If you notice excessive brake lever travel
or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Diesel fuel filter
The Diesel fuel filter is located under the bonnet,
close to the brake fluid reservoir.
If this warning lamp comes on, the filter
must be purged to remove water.
You can also purge the fuel filter regularly, every
time the engine oil is changed.
Bleeding the water in the filter

► Couple a clear hose to the bleed screw
1head.
► Place the other end of the clear hose in a
container.
► Loosen bleed screw 2.
► Switch on the ignition.
► Wait for the scavenge pump to stop.
► Switch off the ignition.
► Tighten bleed screw 2.
► Remove, then drain the clear hose and the
container.
► Start the engine.
► Check that there are no leaks.
HDi engines make use of advanced
technology. Any intervention requires a
special qualification guaranteed by the
CITROËN dealer network or a qualified
workshop .
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50 km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer

In the event of a breakdown
8► Disconnect hose I and directly connect it
to the tyre valve; the cartridge will thereby be
connected to the compressor and the sealant will
not be injected.
If the tyre needs to be deflated, connect hose
I to the tyre valve and press the yellow button
located in the centre of the compressor switch.
Replacing the cartridge

To replace the sealant cartridge, proceed as
follows:
► Disconnect the hose I.
► Turn the cartridge to be replaced anti-
clockwise and lift it.
► Insert the new cartridge and turn it clockwise,
► Reconnect the hose I and connect pipe B to
its location.
The cartridge contains ethylene glycol, which is harmful if swallowed and irritates
the eyes.
It must be kept out of the reach of children.
After use, do not discard the cartridge in standard waste, take it to a
CITROËN dealer or an authorised waste
disposal site.
Spare wheel
Parking
► Park the vehicle where it does not block
traffic: the ground must be level, stable and
non-slippery.
► If the road is sloping or damaged, place an
object under the wheels to act as a chock.
► With a manual gearbox, engage first gear
then switch off the ignition to block the wheels.
► Apply the parking brake and check that the
warning lamp is on in the instrument panel.
► The passengers must get out of the vehicle
and wait where they are safe.
► Put on the high visibility vest and signal that
the vehicle is immobile by using the devices
envisaged by the legislation in force in the
country where you are driving (warning triangle,
hazard warning lamps, etc.).
► Equip yourself with the tools.
