Braking assistance systems
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).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. When braking in an emergency, press
very firmly without releasing the
pressure.
Operating fault
If this warning lamp comes on,
together with the STOP and ABS
warning lamps, accompanied by an

rims), ensure that they conform to the

You must stop as soon as it is safe to do so.

Safety

155
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.When braking in an emergency, press
firmly without releasing the pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability control
(DSC)
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.
Activation
These systems are activated automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem. This is indicated by flashing of this
warning lamp in the instrument panel.
Intelligent traction control
system ("Snow motion")
Depending on version, your vehicle has a
system to help driving on snow: intelligent
traction control .
This system detects situations of difficult
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 adhesion.

Driving recommendations
Observe the driving regulations and remain vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your hands on the wheel so that you are ready to react at
any time to any eventuality.
As a safety precaution, the driver must only carry out actions requiring sustained attention when
the vehicle is stationary.
On a long journey, a break every two hours is strongly recommended.
In difficult weather, drive smoothly, anticipate the need to brake and increase the distance from
other vehicles.Never drive with the parking brake
applied - Risk of overheating and
damage to the braking system!
Risk of fire!
As the exhaust system of your vehicle
is very hot, even several minutes
after switching off the engine, do not
park or leave the engine running over
areas where inflammable substances
and materials are present: grass,
leaves,
etc.
Never leave a vehicle unsupervised
with the engine running. If you have
to leave your vehicle with the engine
running, apply the parking brake
and put the gearbox into neutral or
position


N or P, depending on the type
of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle.
Important!
- check that the depth of water does not exceed 15 cm, taking account of waves
that might be generated by other users,

engine.
If you are obliged to drive through water:
On leaving the flooded road, as soon as
circumstances allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.

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 towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
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 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.
Braking
Towing a trailer increases the braking distance.
To 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 Adjusting the
headlamp beam height , refer to the
corresponding section.
For more information on Weights
, 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.
If the exterior temperature is high, it
is recommended that the engine be
allowed to idle for 1 to 2 minutes after
the vehicle comes to a stop, to facilitate
its cooling.

In wintry conditions, the warning lamp
can stay on for a longer period. When
the engine is hot, the warning lamp
does not come on.
In certain cases, you may have to apply
more force to the steering (wheels on
full lock, for example). If the engine does not start straight
away, switch off the ignition. Wait a
few moments before operating the
starter motor again. If the engine does
not start after several attempts, do not
keep trying: you risk damaging the
starter motor or the engine. Contact
a CITROËN dealer or a qualified
workshop.In temperate conditions, do not leave
the engine at idle to warm up but move
off straight away and drive at moderate
speed.
Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion
engines emit toxic exhaust gases,
such as carbon monoxide. Danger of
intoxication and death!
In very severe wintry conditions
(temperatures below -23°C), to ensure
the correct operation and durability of
the mechanical components of your
vehicle, engine and gearbox, it is
necessary to leave the engine running
for 4 minutes before moving off.
