Park Assist
This system provides active assistance with parking, detecting a parking space then controlling the steering to park in the space.
It controls the steering while the driver manages the accelerator, brakes, gears and clutch (manual gearbox). During phases of entry into and exit from
a parking space, the system provides visual and audible information to the driver in order to make the manoeuvre safe. It may be necessary to move
forwards and backwards more than once.The Park Assist system cannot in any
circumstances replace the care and
responsibility of the driver.
The driver must remain in control of
their vehicle ensuring that the space
remains clear during the manoeuvre.
In some circumstances, the sensors
may not detect small obstacles located
in their blind spots. Changing tyre sizes (out-size tyres,
winter tyres, ...) can inter fere with
the correct operation of the parking
assistance system.
During a manoeuvre the steering wheel
turns quickly: do not hold the steering
wheel, do not place your hand between
the spokes of the steering wheel and
take care with loose and bulky clothing,
scarves, handbags... There is a risk of
injury. For entry into a parking space (parallel
parking) the system does not detect
spaces which are clearly much smaller
or larger than the size of the vehicle.
This "parking assistance" system
is activated automatically during
manoeuvres; it is therefore possible
that a symbol comes on in the screen,
accompanied by an audible signal,
without affecting the manoeuvre.
The selection of the type of manoeuvre
(entering or exiting a parallel parking
space) prevents a change to STOP
mode of Stop & Start.
In STOP mode, this selection restarts
the engine.
The driver can take control at any time by gripping the steering wheel.
The system provides assistance in entering and
exiting a parking space when parallel parking.

Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking
and provides improved control in corners, in
particular on poor or slippery road sur faces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered according to the speed at which
the brake pedal is pressed. This is felt by a
reduction in the resistance of the pedal and an
increase in the effectiveness of the braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Safety

136
Dynamic stability control (DSC)
and anti-slip regulation (ASR)The DSC system offers exceptional
safety in normal driving, but this should
not encourage the driver to take extra
risks or drive at high speed.
The correct operation of the system
depends on observation of the
manufacturer's recommendations
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the assembly and
repair procedures used by CITROËN
dealers.
After an impact, have the system
checked by a CITROËN dealer or a
qualified workshop.
Activation
These systems are activated automatically
each time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation if
the engine and brakes.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate
the DSC system, so that the wheels can move
freely and regain grip.
This is indicated by flashing of this
warning lamp in the instrument panel.
Operating fault
But it is recommended that the system be
reactivated as soon as possible. F

P
ress the button.
This warning lamp and the indicator lamp
in the button come on: the DSC system no
longer acts on the operation of the engine.
Reactivation
The system is reactivated automatically each
time the ignition is switched back on or from
30 mph (50 km/h). F

P
ress the button again to
reactivate it manually. If this warning lamp comes on,
accompanied by an audible signal
and a message, this indicates a fault
with the system.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.

Driving advice
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 performance. 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 on a long
mountain type of descent, 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.
Refer to the "Technical data" section for details
of the weights and towed loads which apply to
your vehicle.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.
When not towing a trailer, remove the
quickly-detachable tow ball before
driving.

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
Brake pads
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Brake disc wearOnly 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.Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the maintenance and
warranty guide for the details of
the level checking interval for this
component.
Electronic gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the maintenance and
warranty guide for details of the level
checking interval for this component.
Parking brake
If excessive travel or 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. To avoid damaging the electrical units,
the use of a high pressure washer
in the engine compartment is strictly
prohibited.
have the condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
