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 (ESP)


Anti-slip regulation (ASR)
and electronic stability
control (ESC)

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")
Your vehicle has a system to help driving on
snow: intelligent traction control.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of adhesion.
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.
In extremely severe conditions (deep snow,
mud, ...), when it proves impossible to move off,
it may be useful to temporarily deactivate the
ESP/ASR systems to allow the wheels to spin
freely and so allow movement of the vehicle.

209Driving

Moving off




With your foot on the brake, select
position P
or N
.


Start the engine.
If this procedure is not followed, there is an
audible signal, accompanied by a message in
the multifunction screen.



With the engine running, press the brake
pedal.


Release the parking brake, unless it is
programmed to automatic mode.


Select position R
, D
or M
,


Gradually release the brake pedal.
The vehicle moves off immediately.

If position N
is engaged inadvertently
while driving, allow the engine to
return to idle then engage position D
to
accelerate.
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.
When the engine is running, never
leave children in the vehicle without
supervision.
When carrying out maintenance with
the engine running, apply the parking
brake and select position P
.



Automatic operation




Select position D
for automatic
changing
of the six gears.
The gearbox then operates in auto-adaptive
mode, without any inter vention 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 lever, 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 efficient 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.

Electric parking brake

This system does not require any
routine ser vicing. 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.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
















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 ser vices.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.

For more information, refer to the "Electric
parking brake - Operating faults" section.

Driving advice


Distribution of loads




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




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.



To 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.



If the warning lamp and the STOP

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

The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.



Braking

Towing a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.


Ty r e s




Check the tyre pressures of the towing
vehicle and of the trailer, obser ving the
recommended pressures.



Lighting




Check the electrical lighting and signalling
on the trailer.

Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
