Safety
automatic post collision braking is not available,
as it can occur in destructive accidents or in
other specific accident scenarios.
It is possible to override the automatic braking by
pressing the brake pedal or accelerator pedal.
Operating conditions
The system operates, if the following conditions
are met:
–
Airbags or pyrotechnic seat belt pretensioners
have been deployed by the collision.
–


Braking systems and electric functions remain
continuously operational during and after
collision.
–


Driver has not depressed the brake or
accelerator pedal.
Malfunction
In the event of a
malfunction, one of these
warning lamps will come on fixed on the
instrument panel, accompanied by the Service
warning lamp, the display of a message and an
audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
Emergency braking
assistance (EBA)
This system reduces the emergency stopping
distance, by optimising the braking pressure. It is triggered in relation to the speed at which
the brake pedal is depressed. The effect of this
is a 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 (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
Reactivate the system as soon as the level of
grip permits.
This function is set via theDriving/Vehicle touch screen menu.
Deactivation is confirmed by the lighting
of this indicator lamp on the instrument
panel and the display of a message.
The ASR system is reactivated automatically
every time the ignition is switched off, or at
speeds over 31 mph (50
km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a malfunction, this warning
lamp comes on 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

11 8
Driving
Operating limits
The system may issue an alert when the vehicle is travelling on a long, straight
road with smooth road surface even if the
driver thinks they are holding the steering
wheel correctly.
The system may not operate or may produce
unsuitable corrections to the steering in the
following situations:
–

Poor visibility (insufficient road lighting,
snowfall, rain, fog).
–


Dazzle (headlamps of an oncoming vehicle,
low sun, reflections on a wet road surface,
leaving a tunnel, alternating light and shade).
–


Windscreen area in front of the camera
dirty

, misted up, frost-covered, snow-covered,
damaged or covered by a sticker.
–

Lane markings eroded, partially hidden (snow
,
mud) or multiple (roadworks, surface joints).
–

T

ravelling in a tight bend.
–

Winding roads.
–


Presence of a tarmac joint on the road.
Risk of undesirable operation
The system should be deactivated in the following situations:
–

Driving with a "space-saver" type spare
wheel.
–


When towing or with a bicycle carrier
attached to a towing device, particularly when
a trailer is not connected or the trailer is not
an approved type.
–

Adverse weather conditions.
–


Driving on slippery road surfaces (risk of
aquaplaning, snow

, ice).
–

In roadworks or toll booth areas.
–


Driving on racing circuits.
–


Driving on a rolling road.
Malfunction
In the event of a malfunction, the
Service warning lamp comes on
and this (orange) symbol appears 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.
Active lane departure warning system
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The system corrects the vehicle's trajectory by
alerting the driver as soon as it detects a risk of
involuntary
lane departure or crossing of a verge
or hard shoulder (depending on version).
To do this, the system uses a camera, placed on
the upper part of the windscreen, identifying the
lane markings on the ground and the side of the
road (depending on version).
This system is particularly useful on
motorways and main roads.


Operating conditions
– Vehicle speed between 40 and 112 mph (65
and 180 km/h).
–

Road marked with a central dividing line.
–


Steering wheel held in both hands.
–


Direction indicators not activated.
–


ESC system activated and operational.
The system helps the driver only if there is a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or braking.
The driver must hold the steering wheel with
both hands in a way that allows control to
be maintained in circumstances where the
system is not able to intervene (for example, if
the central dividing line disappears).
Operation
As soon as the system identifies a risk of
involuntarily crossing one of the lane markings

Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluids must comply with the manufacturer's requirements and with
the vehicle's engine.
Take care when working under the bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►

Grasp the dipstick by its coloured grip and
pull it out completely

.
►

Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil
level: the correct level is between marks A
(max)
and B (min).
Do not start the engine if the level is:
–

above mark
A: contact a CITROËN dealer or a
qualified workshop.
–

below mark B

: top up the engine oil
immediately.

necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
The start of clogging of the particle filter is
indicated by the temporary lighting of this
warning lamp, accompanied by an alert
message.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37
mph (60 km/h) until the warning lamp
goes off.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice
water vapour coming from the exhaust while
accelerating. These emissions have no
impact on the vehicle’s behaviour and the
environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
