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 (
d
SC)
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 adhesion 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 slip 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.
Safety

183
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 ambient
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 hadlamp beam height
of your vehicle.
For more information on adjusting the
headlamp beam height, refer to the
corresponding section.
For more information on weights (and
the towed loads which apply to your
vehicle) refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.

Moving off

If this procedure is not followed, an audible
signal is heard, accompanied by a message in
the instrument panel screen.

pedal.
F

Sel
ect position R ,
d or M. If the parking brake does not release
automatically, check that the front
doors are fully closed.
When the engine is running at idle, with
the brakes released, if position R
,
d or
M is selected, the vehicle moves even
without the accelerator being pressed.
Never leave children unsupervised in
the vehicle when the engine is running.
When carrying out maintenance with
the engine running, apply the parking
brake and select position P .
Automatic operation
F Select position d for automatic changing
of the six gears.
The gearbox then operates in auto-adaptive
mode, without any intervention on the part
of the driver. It continuously selects the most
suitable gear according to the style of driving,
the profile of the road and the load in the
vehicle.
For maximum acceleration without touching
the selector, press the accelerator pedal down
fully (kick down). The gearbox changes down
automatically or maintains the gear selected
until the maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide effective engine
braking.
If you release the accelerator sharply, the
gearbox will not change to a higher gear for
safety reasons.
Never select position
n while the
vehicle is moving.
Never select positions P or R unless
the vehicle is completely stationary.
If position
n
is engaged inadvertently
while driving, allow the engine to
return to idle then engage position
d
to
accelerate.
If you do not press the brake pedal when
trying to move the gear selector out
of position P , this warning lamp or this
symbol appears in the instrument panel accompanied
by a message, flashing of the P symbol, the display of
a message and an audible signal.
F Check that the display in the instrument panel agrees with the position engaged.
F

G
radually release the brake pedal.
The parking brake is released manually, the
vehicle moves off.
If the parking brake is on and automatic mode
is activated, accelerate progressively.

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.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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Manual parking brake
If a loss of effectiveness of this
system is noticed, the parking brake
must be checked, even between
two
services.
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.
For more information on the electric parking
brake, refer to the corresponding section.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
