Ease of use and comfort
Additional pre-heater or programmable additional
heating
This is an additional, programmable and
independent system that heats the hot water
loop of the Diesel engine to facilitate starting.
It improves the performance of the defrosting
and demisting and, if fitted to the vehicle, that of
the heated seats.
The passenger compartment’s temperature rises
more quickly.
This system must be programmed to be started
before entering the vehicle.
Automatic additional heating
This is an additional system that starts
automatically when the ignition is switched on. Its
activation depends on the outside temperature
and the temperature inside the vehicle.
It switches off automatically as soon as the

Safety
Airbags

The airbags have been designed to optimise the
safety of the occupants in the event of a serious
collision; they work in conjunction with the force
limiting seat belts.
In the event of a serious collision, electronic
detectors record and analyse any abrupt
deceleration of the vehicle:
– if there is a violent impact, the airbags deploy
instantly and help better protect occupants of the
vehicle; immediately after the impact, the airbags
deflate rapidly in order not to hinder the visibility
or the possible exit of the occupants.
– in the case of a minor or rear impact or in
certain rollover conditions, the airbags are not
deployed; the seat belt alone contributes towards
ensuring your protection in these situations.
The airbags do not operate when the
engine is not running.
This equipment will only deploy once. If a
second impact occurs (during the same or a
subsequent accident), the airbag will not be
deployed again.
return and slide the whole thing, then release to
lock.
The belt associated with the central seat is not
height adjustable.
If the driver's seat belt is unfastened,
START mode of Stop & Start will not be
invoked. The engine can then only be
restarted using the key.
Rear seat belts

The rear seats / bench seats are fitted with
three-point inertia reel seat belts.
The central seat has a guide and an inertia reel,
which are attached to the backrest.
Each side seat is provided with a support to
hang the belt buckle when not in use.
Fastening
► Pull the strap, then insert the tongue in the
buckle.
► Check that the seat belt is fastened correctly
by pulling the strap.
Unlocking
► Press the red button on the buckle.
► Guide the seat belt as it is reeled in.
Advice
The driver must ensure that passengers
use the seat belts correctly and that they
are all fastened before setting off.
Wherever seated in the vehicle, you must
always fasten the seat belt, even for short
journeys.
Do not interchange the seat belt buckles, as
they will not fulfil their role fully.
Before and after use, ensure that the seat belt
is reeled in correctly.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
Installation
The lower part of the strap must be
positioned as low as possible on the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
In order to be effective, a seat belt:
– must be tightened as close to the body as
possible;
– must be pulled in front of you with a smooth
movement, ensuring that it is not twisted;
– must only be used to secure one person;
– must not show signs of tearing or fraying;
– must not be changed or modified, in order
to avoid affecting its performance.
Recommendations for children
Use a suitable child seat if the passenger
is less than 12 years old or shorter than one
and a half metres.
Never use the same seat belt to secure more
than one child.
Never carry a child on your lap.
For more information on Child seats, refer to
the corresponding section.
Maintenance
In accordance with current safety
regulations, for all repairs on your vehicle's
seat belts, go to a qualified workshop with
the skills and equipment needed, which a
CITROËN dealer is able to provide.
Have the seat belts checked regularly by a
CITROËN dealer or a qualified workshop,
particularly if the straps show signs of
damage.
Clean the seat belt straps with soapy water or
a textile cleaning product, sold by CITROËN
dealers.

Driving
Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
► Monitor your environment and keep your
hands on the wheel to be able to react to
anything that may happen any time.
► Drive smoothly, anticipate the need for
braking and maintain a longer safety distance,
especially in bad weather.
► Stop the vehicle to carry out operations that
require close attention (such as adjustments).
► During long trips, take a break every two
hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In severe wintry conditions (temperature
below -23°C), let the engine run for 4
minutes before moving off, to ensure the
correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damage to the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (dry grass, dead leaves, etc.). The
exhaust system of your vehicle is very hot,
even several minutes after the engine stops.
Risk of fire!
Never leave a vehicle unattended with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P (depending on the
type of gearbox).
Never leave children inside the vehicle
unsupervised.
To assure the durability of your vehicle and your safety, remember that certain precautions,
described hereafter, should be taken when
driving your vehicle :
Manoeuvre cautiously, at low speed
The dimensions of your vehicle differ from those
of a light vehicle, in width, in height, as well as in
length, and some obstacles will be more difficult
to notice.
Manoeuvre slowly.
Before turning, check that there are no obstacles
at mid-height along the sides.
Before reversing, check that there are no
obstacles, particularly at high level behind the
vehicle. Be aware of the external dimensions, if ladders
are fitted.
Load the vehicle correctly
With a load carried, the vehicle must remain
within the maximum authorised weight, the
Gross Vehicle Weight.
To avoid upsetting the balance of the vehicle,
the load should be centred and the heaviest part
placed on the floor in front of the rear wheels.
It is inadvisable to place heavy loads on a roof
rack.
Loading also implies adherence to the maximum
load of the roof bar anchor points. Adhere to
the maximum permissible weight, according to
CITROËN dealer specifications.
Loads must be securely lashed down.
A load that is not properly secured inside the
vehicle may affect vehicle handling and create a
risk of accident.
If your vehicle is fitted with a drop-side back, the
height and width of the load must remain within
the overall dimensions of the vehicle.
Drive the vehicle in a prudent and efficient
way
Take corners gently.
Anticipate the need to brake as the stopping
distance is increased, particularly on wet or icy
roads.
Be aware of the effect of side winds on the
vehicle.
Effective eco-driving saves fuel; accelerate
progressively, anticipate the need to slow down
and adapt your speed to suit the situation.
Indicate changes of direction well in advance so
that you are seen by other road users.
Take care
The tyres must be inflated to at least the
pressures indicated on the label, even over-
inflated by 0.2 to 0.3 bar for long journeys.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
► check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
► deactivate the Stop & Start function,
► drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
► do not stop and do not switch off the engine.

► do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the density
of the air decreases with altitude and the
performance of the engine reduces.
New vehicle: do not pull a trailer before
having driven at least 620 miles (1,000
kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill increases the temperature
of the coolant. The maximum towable load
depends on the gradient and the exterior
temperature. The cooling capacity of the fan
does not increase with engine speed.
► Reduce speed and lower the engine speed,
so as to limit the heating-up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.

► Pull the control located on the side of the
dashboard towards you.
On the outside

► Push the lever located above the grille
upwards and lift the bonnet.
Do not open the bonnet under very windy
conditions.
When the engine is hot, handle the lever and
the stay with care (risk of burns).


► Unclip the stay and rotate it to insert it into
the first slot and then into the second slot.
Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water (rain,
washing, etc.) be limited.
Closing the bonnet
► Before closing the bonnet, replace the stay in
its housing. ►
Lower the bonnet and release it near the end
of its travel. Check the bonnet is locked.

Practical information
A clogged passenger compartment filter can adversely affect air conditioning
system performance and generate
undesirable odours.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
In addition to the catalytic converter, this filter
actively contributes to the preservation of
air quality by trapping the unburnt pollutant
particles. Black exhaust fumes are therefore not
emitted.
Operation
This filter, inserted into the exhaust system,
accumulates the carbonaceous particles. The
engine management computer automatically
and periodically manages the removal of
carbonaceous particles (regeneration).
The regeneration procedure is triggered
according to the amount of accumulated
particles and the conditions of use of the vehicle.
During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
Screenwash and headlamp
washer fluid
To check the level or top up this fluid on
vehicles fitted with headlamp washers,
immobilise the vehicle and switch off the engine.
Reservoir capacity: approximately 5.5 litres.


To access the filler cap, pull the telescopic filler
neck and unclip the cap.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular on the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.

During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust while
accelerating. This has no impact on the
vehicle’s behaviour and the environment.
Due to the high exhaust temperatures
caused by the normal operation of the
particle filter, it is recommended not to park
the vehicle on flammable materials (grass, dry
leaves, pine needles, etc.) to avoid any risk of
fire.
Saturation/Regeneration
If there is a risk of clogging, this warning
lamp comes on, accompanied by a
message on the instrument panel display.
This warning is due to the start of saturation of
the particle filter (exceptionally long urban driving
conditions: reduced speed, traffic jams, etc.).
In order to regenerate the filter, it is
recommended to drive as soon as possible -
when traffic conditions and regulations permit
- at a speed of at least 37 mph (60 km/h), with
an engine speed above 2,000 rpm for about
15 minutes (until the warning lamp and/or the
message disappear).
If possible, avoid switching off the engine
before the end of filter regeneration; repeated
interruptions can lead to early deterioration of the
engine oil. It is not recommended to terminate
the filter regeneration with the vehicle stationary.
Malfunction
If this alert persists, do not ignore this warning;
this indicates that a malfunction has occurred in
the exhaust system/particle filter assembly.
Have the assembly checked by a CITROËN
dealer or a qualified workshop.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Brake pads
Brake wear depends on the style of
driving, particularly in the case of vehicles
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 fluid level indicates that the brake pads
are worn.
If this warning lamp comes on, have the
brake pads checked by a CITROËN
dealer or a qualified workshop.
After washing the vehicle, moisture, or in
wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.

Practical information
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
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
