Electronic stability control (ESC)
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 better control in
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered according 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.
Traction control (TRC)
This system 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
followed by the vehicle and that required by the
driver, this system 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.

Safety

106
Illumination of this warning lamp,
accompanied by an audible signal,
indicates that there is a fault with the
electronic brake force distribution
(EBFD), which could cause loss of
control of the vehicle when braking.
Operation
Illumination of this warning lamp,
accompanied by an audible signal,
indicates that there is a fault with
the ABS system, which could cause
loss of control of the vehicle when
braking.
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal.
In emergency braking, press
very firmly without releasing
the

pressure.
Yo u must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
Dynamic stability control (DSC)
and traction control (TRC)
Activation
These systems are activated automatically
each time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation if
the engine and brakes.
Activation of the DSC system is
signalled by the flashing of this
indicator lamp in the instrument panel,
accompanied by an audible signal.
Activation of the TRC system is
signalled by the flashing of this
indicator lamp in the instrument panel.
Drive carefully at reduced speed, and contact a
CITROËN dealer or a qualified workshop.
Safety

107
The TRC and DSC systems offer
increased safety in normal driving, but
should not encourage the driver to take
extra risks or drive at high speed.
The correct operation of these
systems depends on observation of
the manufacturer's recommendations
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the assembly and
repair procedures used by CITROËN
dealers.
After an impact, have the system
checked by a CITROËN dealer or a
qualified workshop.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate the
DSC and TRC systems, so that the wheels can
spin freely and regain grip.
Operating fault
However, it is recommended that theses
systems be reactivated as soon as possible.F

P
ress this button briefly.
This warning lamp comes on: the
TRC system no longer acts on the
operation of the engine.
Reactivation
The TRC and DSC control systems are
reactivated automatically every time the engine
is started. F

P
ress the button again to
reactivate it manually. Illumination of this warning lamp,
accompanied by an audible signal,
indicates a fault with the system.
Drive carefully at reduced speed and contact
a CITROËN dealer or a qualified workshop to
have the system checked.
Deactivation of the TRC system only

ehicle stationary , press this
button for at least than 3 seconds.
These warning lamps come
on: the TRC and DSC
systems no longer act on
the operation of the engine. When the TRC system only is deactivated, it is
reactivated as the vehicle's speed increases.
When both the TRC and DSC systems are
deactivated, they do not reactivate themselves
even if the speed of the vehicle increases.

Active City Brake
Active City Brake is a driving assistance system that aims to avoid a frontal collision or reduce the speed of an impact if the driver does not react or
reacts too late (brake application too late).This system is designed to improve
driving safety.
It remains the driver's responsibility to
continuously monitor the state of the
traffic and to assess the distances and
relative speeds of other vehicles.
Active City Brake can in no
circumstances replace the need for
vigilance on the part of the driver.
Never look at the laser sensor through
an optical instrument (magnifying glass,
microscope...) at a distance of less than
10 centimetres: risk of eye injury.
Automatic braking occurs later than if
done by the driver, so as to intervene
only when there is a high risk of
collision.
Principle
Using a laser sensor and a camera located at
the top of the windscreen, this system detects
a vehicle running in the same direction or
stationary ahead of your vehicle.
When necessary, the vehicle's braking system
is operated automatically to reduce the speed
of impact or to help avoid a collision with the
vehicle ahead.
Conditions for activation
Active City Brake only operates if the following
conditions are met:
●
t
he engine is running,
●

t
he vehicle is in a for ward gear,
●

t
he speed is between 9 and 87 mph
(15
and 140 km/h) for triggering the alert ;
the difference in speed between your
vehicle and the one ahead is more than
about 9
mph (15 km/h),
●

t
he speed is between about 18 and 50 mph
(30 and 80 km/h) for braking assistance ;
the difference in speed between your
vehicle and the one ahead is more than
about 18 mph (30 km/h),
●

t
he speed is between about 6 and 50 mph
(10 and 80 km/h) for automatic braking ;
the difference in speed between your
vehicle and the one ahead is more than
about 6 mph (10 km/h),
●

t
he braking assistance systems (ABS,
EBFD, EBA) are not faulty,
●

t
he trajectory control systems (TRC, DSC)
are not deactivated or faulty,
●

t
he vehicle is not in a tight corner,
●

t
he system has not been triggered during
the previous 10 seconds.

Activation
Press the button, this warning lamp
comes on in the instrument panel.
Operation
Three levels of operation are possible:
● A lert: if a risk of collision with a vehicle is
detected, a warning lamp comes on in the
instrument panel together with an audible
signal. The thresholds for triggering the
alert can be set.
●

Br
aking assistance : increases the
braking started by the driver, only if a risk
of collision is detected.
●

A
utomatic braking : when your vehicle
is too close to or closing too quickly on
the vehicle ahead of you, the system
automatically operates the brakes to
reduce the speed of impact. A collision can
be avoided automatically if the difference
in speed between your vehicle and the one
ahead is not more than 18 mph (30 km/h).
You are then alerted by the display of
this warning lamp, accompanied by
an audible signal. The automatic braking may bring the vehicle to
a complete stop if the situation requires it.
The brake lamps on your vehicle come on to
warn other road users. The triggering of the system may cause
the engine to stall, unless the driver
depresses the clutch pedal quickly
enough during automatic braking.

Fuel tank
Low fuel levelRefuelling
When the low fuel level is reached,
this warning lamp comes on and the
last bar flashes, accompanied by an
audible signal.
You have approximately 5 litres remaining.
In certain driving conditions and depending on the
engine, the distance which can be travelled with the
fuel remaining may be less than 30 miles (50 km).
When the frequency of the flashing increases, you
have approximately 3 litres remaining .
To refuel in complete safety:
F
Y ou must stop the engine and switch off
the ignition (ignition in "LOCK" position
or "OFF" mode) .
F

P
ull the control on the lower dashboard,
driver's side, to release the filler flap.
F

O
pen the fuel filler flap.
If you run out of fuel, the emission
control system warning lamp may come
on in the instrument panel. It will go off
automatically after the engine has been
started a few times. Refuelling must only be done with the engine
stopped
and the ignition switched off (ignition
switch in the " LOCK" position or " OFF" mode).
The capacity of the fuel tank is approximately 35 litres.
Additions of fuel must be of at least 5 litres to
be registered by the fuel gauge.
A label on the inside of the flap reminds you
which type of fuel to use.
There may be an inrush of air when removing
the filler cap. This vacuum is per fectly normal
and results from the sealing of the fuel system.

Quality of the fuel used for
petrol engines
The petrol engines are compatible with
E10 type petrol biofuels (containing
10 % ethanol), conforming to European
standards EN 228 and EN 15376.
E85 type fuels (containing up to 85 % ethanol)
are reserved exclusively for vehicles marketed
for the use of this type of fuel (BioFlex
vehicles). The quality of the ethanol must
comply with European standard EN 15293.
