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).
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 is active if the
vehicle speed is higher than 6 mph (10 km/h).
It is deactivated when the vehicle speed falls
below 3 mph (5 km/h).
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
When the vehicle is stationary
If this warning lamp comes on, accompanied by
the indication on the instrument panel screen, it
indicates a malfunction of the anti-lock braking
system which could result in a loss of control of
the vehicle when braking.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or a qualified workshop as
soon as possible.
When braking in an emergency, press
very firmly without releasing the
pressure. The warning lamp comes on for a few
seconds when the ignition is switched on
(ON position). If it does not switch off or
does not come on, contact a CITROËN
dealer or a qualified workshop.

When the vehicle is moving
If this warning lamp comes
on continuously it indicates a
malfunction of the anti-lock braking
system which could result in a loss of
control of the vehicle on braking.
The two warning lamps comes on at the
same time and the two warnings are
displayed alternately in the instrument
panel screen.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or qualified workshop as
soon as possible.
If these two warning lamps come on, linked
with the warnings on the instrument panel
screen, they indicate a malfunction of the
electronic brake force distribution which could
result in a loss of control of the vehicle on
braking.
You must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop.

Associated systems which contribute to the directional stability of the vehicle within the limits of the laws of physics:
- t raction control (TCl) ,
-

a
ctive stability control (ASC).
Traction control and active stability control
Traction control optimises traction to prevent
wheel spin, by acting on the brakes of the
driving wheels and on the engine.
Active 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.Activation
These systems are activated automatically
each time the vehicle is started.
The illumination of this warning lamp
in the instrument panel indicates
that the ASC and TCL systems are
deactivated.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, ...), it may be advisable to deactivate
the ASC system, so that the wheels can move
freely and regain grip.
This is indicated by the flashing of
this symbol on the instrument panel
screen.
Trajectory control systems
F Press this button, located to the left of the steering wheel, until the symbol appears in
the instrument panel screen.
Operation
They operate when the vehicle speed is higher
than 9 mph (15 km/h).
They come into operation in the event of a grip
or trajectory problem.

For more information on snow chains,
contact a CITROËN dealer or a
qualified workshop.
Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when
braking.
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

F
it the chains following the instructions
provided by the manufacturer.
F

M
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.
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.Use only chains designed for fitment to the type
of road wheels on your vehicle:
Original equipment tyre size Maximum link size
215/70 R16 12 mm
225/55 R18
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.

Advice on driving when towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without
exceeding
it.
Air density decreases with altitude,
thus
reducing engine per formance. Above
1
000 metres, the maximum towing load must
be reduced by 10
% of the GTW and so on for
every 1
000 metres of altitude.
For more information on Petrol weights or
Diesel weights and in particular the towed
loads which apply to your vehicle, refer to the
corresponding section.
Side wind
F Take into account the increased sensitivity to side wind.
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 slope
depends on the gradient and the exterior
temperature.
In all cases, pay attention to the coolant
temperature.
F

I
f this message is displayed, stop your
vehicle as soon as it is safe to do so.
Braking
Towing a trailer increases the braking distance.
To limit heat build-up in the brakes, use of the
engine brake 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 lighting and signalling on the trailer and the adjustment of the vehicle's
headlamps.
For more information on Headlamp
adjustment , refer to the corresponding
section.
If the message flashes slowly, wait for the
engine to cool before topping up the level, if
necessary.
If the message flashes rapidly, contact a
CITROËN dealer or a qualified workshop
without delay.
The rear parking sensors will be
deactivated automatically when a
genuine CITROËN towbar is used.

Coolant level
The coolant level should be between
the two marks.When the engine is warm, the temperature of
the coolant is regulated by the fan.
As the cooling system is pressurised when the
engine is warm, 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.Fluid specification
The coolant must conform to the
manufacturer's recommendations.
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Brake fluid level
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.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might become caught by the
fan blades. To ensure that this measurement is reliable, the
vehicle must be parked on level ground with the
engine cold.
