Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
These systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards improved control in
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The EBFD system manages the braking
pressure wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by
a reduction in the resistance of the pedal and
an increase in the effectiveness of the braking.
Anti-slip regulation (ASR)
This system (also known as Traction Control)
optimises traction in order to limit wheel slip by
acting on the brakes of the driving wheels and
on the engine. It also improves the directional
stability of the vehicle on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
f ollowed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Intelligent traction control
( " Snow motion ")
Depending on version, your vehicle has
a
system to help driving on snow: intelligent
traction control.
This system detects situations of poor sur face
grip that could make it difficult to move off
or make progress on deep fresh snow or
compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel spin to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of grip.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
When lit up continuously, this
warning lamp indicates a fault with
the ABS.
If this warning lamp comes on, in
conjunction with the STOP and ABS
warning lamps, an audible signal
and a
message, it means that the
electronic brake force distribution
(EBFD) is defective.
The vehicle retains conventional braking. Drive
carefully at moderate speed.
You must stop the vehicle as soon as it is
safe to do so.
In both cases, have the system checked by
a

CITROËN dealer or a qualified workshop as
soon as possible.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
When operating under normal conditions,
the ABS may cause the brake pedal to
vibrate slightly.
Safety

105
In emergency braking, press the brake
pedal hard and maintain this pressure.
After an impact, have these systems
checked by a CITROËN dealer or
a


qualified workshop.
Anti-slip regulation (ASR)/
Dynamic stability control
(DSC)
Operation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of
a problem with grip or trajectory.
Deactivation of the ASR
In exceptional conditions (starting a vehicle
w hich 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. F

I
n the Driving
menu, select the " Driving
functions " tab, then " Traction control".
Deactivation is confirmed by the display of
a

message.
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.
Reactivation of the ASR
The system is reactivated automatically every
time the ignition is switched back on or from
31
mph (50 km/h).
Below 31
mph (50 km/h), you can reactivate it
manually:
F

I
n the Driving menu, select the " Driving
functions " tab, then " Traction control".
Operating fault
The illumination of this warning
lamp, accompanied by an audible
signal and a
message, indicates that
there is a
fault with these systems. ASR/DSC
These systems offer increased safety
in normal driving, but they 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.
The correct operation of these systems
depends on observation of the
manufacturer's recommendations, not
only about the wheels (tyres and rims),
braking and electronic components but
also the assembly and repair procedures
used by CITROËN dealers.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.
This is indicated by flashing of this
warning lamp in the instrument
panel. Reactivate the system when grip conditions
allow.
Contact a
CITROËN dealer or a qualified
workshop to have the systems checked.

In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
t emperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a trailer before having driven at least
approximately 620


miles (1,000

kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
adjustment , refer to the corresponding
section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
This electronic engine immobiliser locks the
engine management system a
few moments
after the ignition is switched off, and prevents
starting of the engine by anyone who does not
have the key.
In the event of a
malfunction, you are informed
by a
message in the instrument panel screen.
If this happens, your vehicle will not start;
contact a
CITROËN dealer if required.

These levels of alert are based on the inter-
vehicle time between your vehicle and the
vehicle in front.
They take account of the vehicle dynamics,
the speed of your vehicle and the one in front,
the environmental conditions, the operation of
the vehicle (cornering, pedals pressed, etc.) to
trigger the alert at the best moment.Level 1 (orange) : visual alert only,
signalling to you that the vehicle in
front is very close.
The message " Vehicle close" is
displayed.
Level 2 (red) : visual and audible
alert, warning you that a
collision is
imminent.
The message " Brake!" is displayed.
Where the speed of your vehicle is too fast
approaching another vehicle, the first level
of alert may not be displayed: the level
2
alert may be displayed directly.
Important: alert level 1
is never displayed
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 you
press the brake pedal.
Active Safety Brake
This function, also called automatic emergency
braking, inter venes following the alert 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
frontal collision by your vehicle where the
driver fails to react.
Operation
The system operates under the following
conditions:
-

T
he vehicle's speed does not exceed
37
mph (60 km/h) when a pedestrian is
detected.
-

T
he vehicle's speed does not exceed
50
mph (80 km/h) when a stationary vehicle
is detected.
-

T
he vehicle's speed is between 6 mph and
53
mph (10 km/h and 85 km/h) (versions
with camera alone) or 87
mph (140 km/h)
(versions with camera and radar) when
a
moving vehicle is detected.If the camera and/or radar have
confirmed the presence of a
vehicle
or a
pedestrian, this warning lamp
flashes once the function is acting
on the vehicle's brakes.
With an automatic gearbox, in the event of
automatic emergency braking until the vehicle
comes to a
complete stop, keep the brake
pedal pressed down to prevent the vehicle from
starting off again.
With a
manual gearbox, in the event of
automatic emergency braking until the vehicle
comes to a
complete stop, the engine may stall.
Driving

169
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 fault with the
s ystem, you are alerted by the
illumination of this warning lamp,
accompanied by the display of
a


message and an audible signal.
Lane Departure Warning
System
Using a camera located at the top of the
w indscreen to identify lane markings on the
ground, the system corrects the trajectory of
the vehicle while alerting the driver if it detects
a
risk of involuntary crossing of a line.
This system is particularly useful on motor ways
and main roads.
Conditions for operation
The speed of the vehicle must be between
40 mph and 112 mph (65 km/h and 180 km/h).
The driver must hold the steering wheel with
both hands.
The change of trajectory must not be
accompanied by operation of the direction
indicators.
The ESC system must be activated and fault-
free. This system is a
driving aid that cannot,
in any circumstances, replace the
driver's own vigilance. The driver must
remain in control of the vehicle under all
circumstances.
The system helps the driver only when
there is a risk of the vehicle involuntarily
wandering from the lane it is being driven
in. It does not manage the safe driving
distance, the speed of the vehicle or the
brakes.
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 inter vene
(if lane markings disappear, for example).
It is necessary to obser ve the driving
regulations and take a break every two
hours.Operation
Once the system identifies a risk of the vehicle
i nvoluntarily crossing one of the lane markings
detected, it makes the correction to the
trajectory required to return the vehicle to its
initial path.
The driver will notice a
turning movement of the
steering wheel.
This warning lamp flashes during
trajectory correction.
Contact a

CITROËN dealer or a

qualified
workshop to have the system checked.

Park Assist
This system provides active assistance with
parking: it detects a
parking space then
operates the steering system to park in this
space.
With a
manual gearbox , the driver manages
the accelerator, brakes, gears and clutch.
With an automatic gearbox (EAT6/EAT8) , the
driver manages the accelerator, brakes and
gears.
During phases of entry into and exit from
a
parking space, the system provides visual
and audible information to the driver in order
to make the manoeuvres safe. It may be
necessary to move for wards and backwards
more than once. The driver can take control at any time by
gripping the steering wheel.
This manoeuvring assistance system
cannot, in any circumstances, replace the
need for vigilance on the part of the driver.
The driver must remain in control of their
vehicle ensuring that the space remains
clear throughout the manoeuvre.
In some circumstances, the sensors may
not detect small obstacles located in their
blind spots.
The Park Assist system cannot work with
the engine off.
A. Parallel parking.
B. Exit from a


parallel parking space.
C. Bay parking.
The Park Assist system provides assistance for
the following manoeuvres:

Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic 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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN
dealer or a
qualified workshop.
Electric parking brake
This system does not require any
specific check. However, in the
event of a problem, have the system
checked by a
CITROËN dealer or
a


qualified workshop.
For more information on the Electric
parking brake , refer to the corresponding
section.
Wheels and tyres
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold", at least
once a
month and before a long
j o u r n ey. The pressures given 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 more than 31 mph (50 km/h),
0.3 bar (30 kPa) should be added to the values
given 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
braking efficiency and control of the vehicle's
steering. Regular inspections of the condition
of tyres (tread and sides) and rims are
recommended as well as making sure that
valves are fitted.
Using different size wheels and tyres from
those specified can affect the lifetime of tyres,
wheel rotation, ground clearance and 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.
