Electronic stability control
(ESC)
Electronic stability control integrating the
following systems:
-
a
nti-lock braking system (ABS) and
electronic brake force distribution (EBFD),
-
em

ergency braking assistance (EBA),
-

w
heel anti-slip regulation (ASR) or traction
control,
-
d

ynamic stability control (DSC).
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking and
contributes towards improved control on corners, in
particular on poor or slippery road sur faces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system (EBFD)
manages the braking pressure wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system permits the
optimum braking pressure to be reached
more quickly, therefore reducing the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. The effect of this is
a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
The ASR 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
followed 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.
If you benefit from the Citroën Connect
Box offer with the SOS and assistance
pack included, there are additional
ser vices available to you in your personal
space, via the website for your country.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning
lamp indicates that there is 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, this indicates
that the electronic brake force
distribution (EBFD) is faulty.
You must stop 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.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal.
If you need to brake in an emergency,
press the brake pedal ver y firmly and
keep the pressure applied.

Dynamic stability control (DSC)
and anti-slip regulation (ASR)
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.
Activation
These systems are activated automatically
every time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation
of the engine and brakes.This is indicated by this warning
lamp flashing in the instrument
panel.
Deactivating the ASR
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 move
freely and regain grip. F

I
n the Driving/Vehicle
menu
of the touch screen, select the
" Driving functions " tab, then
" Traction control".
Or depending on version:
F
T
urn the "
Grip control" knob to
this position.
Deactivation is signalled by the
illumination of this warning lamp,
accompanied by a message as
well as illumination of the knob
(depending on version).
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.
Reactivating the ASR
The system is reactivated automatically each
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/Vehicle
menu
of the touch screen, select the
" Driving functions " tab, then
" Traction control".
Or depending on version:
F
T
urn the "
Grip control" knob to
this position.
Operating fault
The illumination of this warning
lamp, accompanied by an audible
signal and a message, indicates that
there is a fault with the system.
After an impact, have the system checked
by a CITROËN dealer or a qualified
workshop.
This is indicated by this warning
lamp flashing in the instrument
panel. It is however recommended that the system be
reactivated as soon as possible.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.

Safety

74
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 obser vation of
the manufacturer's recommendations
regarding as much the wheels (tyres and
rims), braking and electronic components
as 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.Grip control
Special patented traction control system which
improves traction on snow, mud and sand.
This system, the operation of which has been
optimised for each situation, allows you to
manoeuvre in most conditions of poor grip
(encountered when using a passenger car).
Associated with 205/50 R17 all-season M+S
(Mud and Snow) tyres, this system offers a
compromise between safety, grip and traction.
These tyres are efficient in winter and summer
conditions.
The accelerator pedal should be pressed
sufficiently to allow the system to use 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.
An indicator lamp associated with each mode
comes on to confirm your choice.
A specific and additional display appears
temporarily in the touch screen to confirm the
selection made with the knob.
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.F

P
lace the knob in this position.
Every time 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)) F

P
lace the knob in this position.
