Safety
reduction in the resistance of the pedal and an
increase in braking efficiency.
Anti-slip regulation (ASR)/Dynamic stability control
(DSC)
Anti-slip regulation (or traction control) optimises
traction by using engine braking and by applying
the brakes on the driving wheels to avoid one
or more wheels spinning. It also enhances the
vehicle's directional stability.
If there is a difference between the vehicle’s
trajectory and the path desired by the driver, the
dynamic stability control system automatically
uses engine braking and the brakes on one or
more wheels to return the vehicle to the desired
path, within the limits of the laws of physics.
These systems are activated automatically every
time the vehicle is started.
These systems are activated in the event of a problem with grip or trajectory
(confirmed by this warning lamp flashing on the
instrument panel).
Deactivation/Reactivation
In exceptional conditions (moving a vehicle that
is bogged down in mud, stuck in snow, on loose
soil, etc.), it may prove useful to deactivate the
DSC/ASR systems, so that the wheels can move
freely and regain grip.
However, it is recommended that the systems be
reactivated as soon as possible.
Only the ASR system can be deactivated
from the touch screen.
Deactivating using the button or Advanced
Grip Control
Press this button or turn the thumbwheel
to this position.
The indicator lamp in the button or thumbwheel
comes on: the DSC/ASR systems no longer
have an effect on engine operation.
Deactivating using the touch screen
In the "Driving/Vehicle" menu, deactivate
the ASR system.
A confirmation message is displayed and this warning lamp on the instrument panel
comes on.
The ASR system no longer acts on the operation
of the engine.
Reactivating using the button or Advanced
Grip Control
Press this button.
Or
Turn the thumbwheel to this position.
The indicator lamp in the button or thumbwheel
goes off.
Reactivating using the touch screen
In the "Driving/Vehicle" menu, activate
the ASR system.
A confirmation message is displayed and this warning lamp on the instrument panel
goes off.
These systems are reactivated automatically
every time the ignition is switched off, or at
speeds over 31 mph (50
km/h).
Below 31 mph (50
km/h), these systems must be
reactivated manually.
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and
an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
ASR/DSC
These systems enhance safety during
normal driving, but should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels
(tyres and rims), braking and electronic
components, as well as the assembly and
repair procedures provided by CITROËN
dealers.
In order to ensure that these systems remain
effective in wintry conditions, the use of snow

101
Safety
5or all-season tyres is recommended. All four
wheels must be fitted with tyres approved for
your vehicle.
All tyre specifications are listed on the
tyre/paint label. For more information
on Identification markings, refer to the
corresponding section.
Intelligent traction control
("Snow motion")
(Depending on version)
The intelligent traction control system helps
improve grip when driving on snow.
This system detects situations of poor surface
grip that could make it difficult to move off
or make progress on deep fresh snow or
compacted snow.
In these situations, the system limits the amount
of wheel spin to provide the best traction and
trajectory control for the vehicle.
The use of winter tyres is strongly recommended on slippery surfaces.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer snaking.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control system (ESC)
must not have any faults.
The vehicle speed must be between 37 and 99
mph (60 and 160
km/h).
If the system detects that the trailer is
snaking, it applies the brakes to stabilise
the trailer and reduces engine power, if
necessary, to slow the vehicle (indicated by the
flashing of this warning lamp on the instrument
panel and the brake lamps coming on).
For information on weights and towed loads,
refer to the Engine technical data and towed
loads section or your vehicle’s registration
certificate.
To ensure safe driving with a Towing device,
refer to the corresponding section.
Malfunction
If a fault occurs, this warning lamp lights
up on the instrument panel, accompanied
by a message and an audible signal.
To continue towing a trailer, reduce speed and
drive carefully!
Have it checked by a CITROËN dealer or a
qualified workshop.
The trailer stability control system provides an extra safety feature under
normal driving conditions, when following the
recommendations for use of trailers and
current legislation in force in your country. It
must not encourage the driver to take extra
risks, such as using a trailer in unsuitable
conditions of operation (e.g. excessive load,
exceeded nose weight, worn or under-inflated
tyres, faulty braking system) or driving at
excessive speed.
In certain cases, the system may not detect
trailer snaking, particularly with a light trailer
.
When driving on slippery or poor surfaces, the
system may not be able to prevent sudden
trailer snaking.
Advanced Grip Control
(Depending on version)
A special, patented traction control system,
which improves driveability on snow, mud and
sand.
This system, optimised for operation in a range
of conditions, enables you to manoeuvre in most
slippery conditions (encountered during normal
passenger car use).
When combined with all-season Peak Mountain
Snow Flake tyres, this system offers a
compromise between safety, grip and driveability.
The accelerator pedal should be pressed
sufficiently to allow the system to harness the
power of the engine. Operation at high engine
speeds is completely normal.
A five-position selector knob allows you to
choose the setting best suited to the driving
conditions encountered.

102
Safety
An indicator lamp associated with each mode
comes on, accompanied by the display of a
message to confirm your choice.
Operating modes



Standard (ESC)
This mode is calibrated for a low level of wheel spin, based on the different levels
of grip normally encountered on the road.
Whenever the ignition is switched off, the
system automatically resets to this mode.
Snow
This mode adapts its strategy to the conditions of grip encountered for each of
the two front wheels on moving off.
(mode active up to 50 mph (80
km/h))
All terrain (mud, damp grass, etc.)
This mode, when moving off, allows considerable spin on the wheel with the
least grip to optimise clearing of the mud and to
regain grip. At the same time, the wheel with the
most grip is controlled in such a way as to
transmit as much torque as possible.
When moving, the system optimises wheel spin
to respond to the driver's requirements as fully
as possible.
(mode active up to 31 mph (50
km/h))
Sand
This mode allows little spin on the two driving wheels at the same time to allow
the vehicle to move forward and limit the risks of
getting stuck in the sand.
(mode active up to 75 mph (120
km/h))
Do not use the other modes on sand as
the vehicle may become stuck.
Deactivation
You can deactivate the ASR and DSC systems by turning the knob to the "OFF"
position.
The ASR and DSC systems will no longer act on the operation of the engine
or of the brakes in the event of a change of
trajectory.
These systems are reactivated automatically
from 31 mph (50
km/h) and whenever the
ignition is switched on.
Recommendations
Your vehicle is designed principally to
drive on tarmac roads but it allows you to
occasionally drive on other less passable
terrain.
However, it does not permit off-road driving
such as:
–

crossing and driving on terrain which
could damage the underbody or strip away
components (fuel pipe, fuel cooler

, etc.) due
to obstacles or stones in particular,
–

driving on terrain with steep gradients and
poor grip,
–


crossing a stream.
Seat belts
Inertia reel
The seat belts are equipped with an inertia
reel which allows the strap length to adjust
automatically to the shape of the user. The seat
belt returns to its storage automatically when it
is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls

temperature. The fan’s cooling capacity does not
increase with engine speed.
►
Reduce speed and lower the engine speed to
limit the amount of heating produced.
►


Pay constant 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.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The remote control contains an electronic chip
which has a special code. When the ignition is
switched on, this code must be recognised in
order for starting to be possible.
A few seconds after switching off the ignition,
this system locks the engine control system,
therefore preventing the engine from being
started in the event of a break-in.
In the event of a fault, you are informed
by illumination of this warning lamp, an
audible signal and a message on the screen.
The vehicle will not start; contact a CITROËN
dealer as soon as possible.

but the selector is in another position,
place the selector in position P to allow the
engine to be started.
If position N is selected inadvertently while
driving, allow the engine to return to idle, then
select position D to accelerate.
When the engine is running at idle with
the brakes released, if position R, D or M
is selected, the vehicle moves even without
the accelerator being pressed.
Never leave children inside the vehicle
unsupervised.
As a safety measure, never leave the vehicle
without taking your key or remote control with
you, even for a short time.
When carrying out maintenance with the
engine running, apply the parking brake and
select position P.
With an automatic gearbox, never try to
start the engine by pushing the vehicle.
Automatic operation
► Select position D for automatic
changing of the gears.
The gearbox then operates in auto-adaptive
mode, without any intervention on the part of the
driver. It continuously selects the most suitable
gear according to the driving style, the road
profile and the load in the vehicle.

146
Driving
► For maximum acceleration without
touching the selector , fully depress the
accelerator pedal (kick-down).
The gearbox changes down automatically or
holds the gear selected until the maximum
engine speed is reached.
When braking, the gearbox changes down
automatically to provide effective engine braking.
If you release the accelerator sharply, the
gearbox will not shift to a higher gear for safety
reasons.
Never select position N while the vehicle
is moving.
Never select positions P or R unless the
vehicle is completely stationary.
Temporary manual control
of gear changes
You can temporarily assume control of gear
changing using the " +" et "-” steering-mounted
controls. The gear change request will be
executed if the engine speed permits.
This function allows you to anticipate certain
situations, such as overtaking another vehicle or
approaching a bend in the road.
After a few seconds with no inputs via the control
paddles, the gearbox reverts to automatic
operation.
Creeping (moving without
using the accelerator)
This function facilitates manoeuvring of the
vehicle at low speed (when parking, in traffic
jams, etc.).
With the engine at idle, parking brake released
and position D, M or R selected, the vehicle
moves
as soon as you take your foot off
the brake pedal (even without pressing the
accelerator).
As a safety precaution, never leave the vehicle with the engine running and the
doors closed.
Manual operation
► With the selector in position D , press
button M to enable 6- or 8-speed
sequential
gear changing.
The indicator lamp for the button comes on.
►

Operate the "
+" or "-" steering mounted
controls.
M appears and the engaged gears are
shown in succession on the instrument
panel.
►

Y

ou can revert to automatic operation at any
time by pressing button M again.
The indicator lamp for the button goes off.
In manual mode, there is no need to
release the accelerator pedal while
changing gear.
It is only possible to change from one
gear to another if the vehicle speed and
engine speed permit.
If the engine speed is too low or too high,
the selected gear flashes for a few
seconds, then the gear actually engaged is
shown.
When the vehicle is stationary or moving very
slowly, the gearbox automatically selects gear
M1.
To preserve the brakes while descending a steep incline, use engine braking to
reduce your speed (change down or select a
lower gear).
Keeping the brake pedal pressed
continuously for long periods can overheat
the brakes, with the risk of damaging the
braking system or making it inoperative.
Only use the brakes when necessary, to slow
or stop the vehicle.
Depending on the road configuration
(e.g. mountainous road), manual
operation may be preferable.
Automatic operation may not always be
suitable, and does not enable engine braking.

167
Driving
6It is possible that collision warnings are
not given, are given too late or seem
unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
Intelligent emergency
braking assistance (iEBA)
This function supplements braking in the event
that the driver brakes, but not enough to avoid a
collision.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called "automatic emergency
braking", intervenes after the acoustic alert if the
driver does not operate the brake pedal quickly
enough.
The system aims at reducing the speed of
impact or avoiding a collision if the driver fails to
react.
The speed will be reduced by a maximum of 16 mph (25 km/h) (versions
with camera only) or by a maximum of 31
mph (50
km/h) (versions with camera and
radar).
Operation
The system operates subject to the following
conditions:
–

At reduced speed in an urban environment,
when a stationary vehicle, pedestrian or cyclist
is detected.
–


The vehicle's speed is between 6 mph and
53 mph (10

km/h and 85 km/h) (versions with
camera only) or 87 mph (140 km/h) (versions
with camera and radar) when a moving vehicle
is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes.
During the flashing time, the function is not
available.
With an automatic gearbox, in the event of
automatic emergency braking, keep the brake
pedal depressed, also after a complete stop is
reached, to prevent the vehicle from rolling away.
With a manual gearbox, in the event of automatic
emergency braking bringing the vehicle to a
complete stop, the engine may stall.
The driver can override the automatic emergency braking at any time by firmly
turning the steering wheel and/or firmly
depressing the accelerator pedal.

Practical information
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.
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.
Brake disc/drum wear
For any information on checking brake
disc/drum wear, contact a CITROËN
dealer 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 energy
consumption. Non-compliant tyre
pressures cause tyres to wear prematurely
and have an adverse effect on the vehicle's
road holding - risk of accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the
tyres (tread and sidewalls) and rims as well as
the presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless, the shock absorbers have a major impact on
road holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
CITROËN dealer or a qualified workshop.
Timing and accessory kits
The timing and accessory kits are used
from the time the engine is started until it
is switched off. It is normal for them to wear over
time.
A
faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)
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 combines 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

Event data recorders
13Recording event data
Electronic control units are installed in your
vehicle. These control units process data
received from the vehicle's sensors, for example,
or data they generate themselves or exchange
with each other. Some of these control units are
required for the correct operation of your vehicle,
some others assist you while driving (driving or
manoeuvring aids), while others provide comfort
or infotainment functions.
The following contains general information about
how data is processed within the vehicle.
You will find additional information about the
specific data which is downloaded, stored
and transmitted to third parties and what it is
used for in your vehicle under the keyword
"Data protection". This information is directly
associated with the references for the functions
in question contained in the corresponding
vehicle handbook, or in the general terms and
conditions of sale.
This information is also available online.
Vehicle operating data
The control units process the data used for the
operation of the vehicle.
This data includes, for example:
–
Information about the state of the vehicle
(e.g.

speed, travel time, lateral acceleration,
wheel rotation rate, fastened seat belts display).
–

Environmental conditions (e.g.
temperature,
rain sensor, distance sensor). As a general rule, this data is temporary, is
not stored for longer than one operating cycle
and is only used within the vehicle itself. The
control units often record this data (including the
vehicle's key). This function allows either the
temporary or permanent storage of information
about the state of the vehicle, stresses on
components, servicing requirements, as well as
events and technical errors.
Depending on the vehicle's equipment level, the
data stored is as follows:
–

Operating state of system components
(e.g.
filling level, tyre pressures, battery charge
status).
–
Faults and malfunctions in important system
components (e.g.
lamps, brakes).
–
System reactions in specific driving situations
(e.g.
deployment of an airbag, triggering of
stability control and braking systems).
–
Information about events which have
damaged the vehicle.
–

For electric and rechargeable hybrid vehicles,
the traction battery charge level and the
estimated driving range.
In particular circumstances (e.g.
if the vehicle
has detected a malfunction), it may be necessary
to record data which would otherwise simply not
be stored.
When taking your vehicle in for servicing
(e.g.
repairs, maintenance), the stored operating
data may be read along with the vehicle's
identification number and used if necessary.
The personnel working for the servicing network (e.g.
garages, manufacturers) or third parties
(e.g. roadside assistance agents) may read
the vehicle's data. This also applies to work
carried out under warranty and quality assurance
measures.
This data is generally read via the OBD
(On-Board Diagnostics) port fitted by law to
the vehicle. It is used to report on the technical
state of the vehicle or its components and
facilitates the diagnosis of malfunctions, in
compliance with warranty obligations and for
quality improvement. This data, in particular the
information relating to stress on components,
technical events, operator errors and other
malfunctions, is sent to the Manufacturer, if
necessary, along with the vehicle's identification
number. The Manufacturer's liability may also be
engaged. The Manufacturer may also use the
operating data taken from the vehicle for product
recalls. This data may also be used to check the
customer's warranty and any claims made under
warranty.
Any malfunctions stored in the vehicle may be
reset by an after-sales service company during
servicing or repair work, or at your request.
Comfort and infotainment
functions
Comfort settings and personalised settings
may be saved in the vehicle and modified or
reinitialised at any time.
