Braking assistance systems
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and
manoeuvrability of your vehicle when braking,
in particular on poor or slippery sur faces.
Activation
The anti-lock braking system comes into
operation automatically when there is a risk of
wheel lock.
Normal operation of the ABS may make itself
felt by slight vibration of the brake pedal.
Operating fault
If this warning lamp comes on,
accompanied by an audible signal
and a message in the instrument
panel screen, it indicates a fault with
the anti-lock braking system which
could result in loss of control of the
vehicle when braking.
If this warning lamp comes on,
together with the STOP and ABS
warning lamps, accompanied by an
audible signal and a message in the
instrument panel screen, it indicates
a fault with the electronic brake force
distribution which could result in loss
of control of the vehicle when braking.
Emergency braking assistance
System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.
Activation
It is triggered by 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.
Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-

a

nti-lock braking system (ABS),
-

e

lectronic brake force distribution (EBFD),
-

e

mergency braking assistance (EBA).
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.When braking in an emergency, press
firmly without releasing the pressure.
When braking in an emergency,
press very firmly without releasing
the

pressure. You MUST stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or a
qualified workshop.

Trajectory control systems
Anti-slip regulation (ASR) and dynamic stability
control (DSC)
Activation
This is indicated by flashing of this
warning lamp in the instrument panel.
Your vehicle has a system to improve traction
on snow: intelligent traction control
.
This system detects situations of low adhesion
that might make moving off and progress
difficult on deep fresh snow or compacted
snow.
In these situations the intelligent traction
control system regulates the amount of wheel
slip to optimise the traction and trajectory
control of your vehicle.
For vehicles with Hydractive III + suspension,
manual adjustment of ground clearance to
the intermediate position improves further the
ability to make progress in deep snow (see the
relevant paragraph).
The anti-slip regulation (also known as traction
control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability control acts on the
brake of one or more wheels and on the engine
to keep the vehicle on the trajectory required
by the driver, within the limits of the laws of
physics.
Intelligent traction control
system ("Snow motion")
These systems are activated automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.
The use of snow tyres is strongly
recommended on sur faces with low
adhesion.

Reactivation
Operating fault
Illumination of this warning lamp and
the lamp in the deactivation button,
accompanied by an audible signal
and a message, indicate a fault with
the system.
Deactivation
Reactivate the systems as soon as the level of
grip permits.F

P
ress this button.
The indicator lamp in the button
comes on.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The DSC and ASR systems no longer act
on the operation of the engine and on the
brakes in the event of a involuntary change of
trajectory.
F

P
ress this button again.
The indicator lamp in the button
goes
off.
The systems are reactivated automatically
each
time the ignition is switched back on or
from 30
mph (50 km/h).
Below 30 mph (50 km/h), you can reactivate
them manually:
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 ASR, so that the wheels can turn
freely and regain grip.

Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels.
Take account of the legislation in force
in your country on the use of snow
chains and the maximum running speed
authorised.Avoid driving with snow chains on roads
that have been cleared of snow, to
avoid damaging your vehicle's tyres and
the road sur face. If your vehicle is fitted
with alloy wheels, check that no part of
the chain or its fixings is in contact with
the wheel rim.
Advice on installation
F If you have to fit the chains during a
journey, stop the vehicle on a flat sur face
on the side of the road.
F

A
pply the parking brake and position any
wheel chocks to prevent movement of your
vehicle.
F

ove off gently and drive for a few
moments, without exceeding 30 mph
(50
km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened.
Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:
Original tyre size Chain specification
225/60 V16 Maximum link size:
9 mm
225/55 W17
245/45 W18 These tyres cannot
be fitted with chains
245/40 Y19
For more information on snow chains, contact a
CITROËN dealer or a qualified workshop. It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.

Blanking cover
When towing, you must remove the blanking
cover in the front bumper as well as the bonnet
seal if fitted.
Contact a CITROËN dealer or a qualified
workshop for this.
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 Adjusting the
headlamps , refer to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Cooling
Towing a trailer on a slope increases the
temperature 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 towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.

Brake fluid level
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the fluid
Refer to the manufacturer's service schedule
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.
Power steering or power
steering and suspension
fluid level
For topping up, it is necessary to go
to a CITROËN dealer or a qualified
workshop.
Coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
Fluid specification
The coolant must conform to the
manufacturer's recommendations. The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top-up the level. When the engine is warm, the temperature of
the coolant is regulated by the fan.

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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Manual parking brake
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.
If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between

two

services.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
Electric parking brake
This system does not require any
routine servicing. 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.
