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.

Safety

108
At a speed above 12 mph (20 km/h), these
w arning lamps flash, associated with an
audible signal, for two minutes. Beyond this
period of time, the warning lamps stay on
continuously until the seat belts are fastened.
Rear seat belts not fastened alert
When the ignition is switched on, with the
engine running or the vehicle moving above
6
mph (10 km/h), warning lamp A and the
corresponding dots in warning lamp B come on
for around thirty seconds, if one or more rear
passengers have not fastened their seat belts.
Seat belts unfastened alert
After the ignition is switched on, warning lamp
A and the corresponding dots in warning lamp
B come on if the driver and/or one or more
passengers unfasten their seat belts.
These warning lamps flash for 30
seconds,
accompanied by an audible signal. Beyond
this period of time, the warning lamps stay on
continuously until the seat belts are fastened.
Advice
The driver must ensure that passengers
use the seat belts correctly and that they
are all fastened before setting off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for
short journeys.
Do not interchange the seat belt buckles
as they will not fulfil their role fully.
The seat belts are fitted with an inertia
reel permitting automatic adjustment of
the length of the strap to your size. The
seat belt is stowed automatically when not
in use.
The inertia reels have an automatic
locking device at the time of a
collision,
during sudden braking or if the vehicle
turns over. You can release the device by
pulling the strap firmly and then releasing
it so that it reels in slightly.
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:
-

b
e tightened as close to the body as
possible,
-

b
e pulled in front of you with a smooth
movement, checking that it does not
twist,
-

b
e used to restrain only one person,
-

n
ot show any signs of cuts or fraying,
-

n
ot be converted or modified 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 allow a
child to travel on your lap.
For more information on Child seats ,
refer to the corresponding section.

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

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.

Ser vice warning lamp comes on in
the instrument panel, accompanied
by a
message and an audible signal. Do not exceed 62
mph (100 km/h), local speed
restrictions permitting.
Have it checked by a CITROËN dealer or
a

qualified workshop.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may then
feel a

substantial jolt when changing from P to
R and from N to R . This jolt will not cause any
damage to the gearbox.
Gear efficiency indicator
This system reduces fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
Gear efficiency recommendations are for
information only. In fact, the road layout, the
traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued
by the system.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode.

Have it checked by a CITROËN dealer or
a qualified workshop.
If a
fault occurs in STOP mode, the engine may
stall.
All of the instrument panel warning lamps come
on.
Depending on version, an alert message may also
be displayed, asking you to place the gear lever in
position N and press the brake pedal.
It is then necessary to switch off the ignition and
start the engine again using the "START/STOP"
button.
The Stop & Start requires the use of
a 12 V battery of special specification and
technology.
All work on this type of battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
For more information on the 12
V batter y,
refer to the corresponding section.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
the risk of injury related to an automatic
change to START mode. Driving on flooded roads
Before driving in a
flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving advice ,
particularly on flooded roads, refer to the
corresponding section.
Tyre under-inflation
detection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure of the four
tyres when the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change .
The system triggers an alert as soon as it
detects a
drop in the pressure of one or more
tyres. The under-inflation detection system does
not replace the need for vigilance on the
part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a


long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section.
