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.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.
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 headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding section.

Never press the accelerator and brake
pedals at the same time. Braking and
acceleration should be done only with
the right foot. Pressing both pedals
together risks damaging the gearbox. If the brake does not release
automatically, check that the front doors
are correctly closed. Never leave children unsupervised in
the vehicle when the engine is running.
When carrying out a maintenance
operation with the engine running, apply
the parking brake and select position P
.Never select position P or R unless the
vehicle is at a complete stop with the
brake applied.
When you want to engage reverse,
to avoid jolts, do not accelerate
immediately after engaging R
.
Changing into position R is
accompanied by an audible signal. Never select position N when driving.
If position N
is engaged in error when
moving, allow the engine to idle, then
engage position D to accelerate.
When the engine is running at idle,
brakes released, if position R

Collision Risk Alert and Active Safety Brake
This system includes three functions:
- C ollision Risk Alert (alert if there is a risk of
collision),
-

I
ntelligent emergency braking assistance,
-

A
ctive Safety Brake (automatic emergency
b r ak ing).
Collision Risk Alert : it warns the driver if their
vehicle is at risk of collision with the vehicle in
front or a pedestrian present in their traffic lane.
Intelligent emergency braking assistance:
it completes the braking action taken by the
driver if this is inadequate.
Active Safety Brake: it intervenes following
the alert if the driver does not react quickly
enough and does not operate the vehicle's
brakes.
If the driver fails to act, the system
contributes towards avoiding a collision or
limiting its severity by reducing the speed
of your vehicle. This system is designed to assist the
driver and improve road safety.
It is the driver's responsibility to
continuously monitor the state of
the traffic, observing the driving
regulations.
This system does not avoid the need for
vigilance on the part of the driver.
The vehicle is fitted with a radar located in the front bumper and a camera at the top of the
windscreen.
Conditions for activation and operation
The system is active from about 4 mph (7 km/h)
and is deactivated below about 3 mph (5 km/h).
It takes account of:
-

v
ehicles running in the same direction or
stationary,
-

p
edestrians present in the traffic lane
(bicycles, motorcycles, animals and objects
on the road are not necessarily detected).

Active Safety Brake
This function, also called automatic emergency
braking, aims to reduce the speed of impact or
avoid a frontal collision by your vehicle where
the driver fails to react.
Using a radar and a camera, this function acts
on the vehicle's braking system.Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop,
the automatic braking is maintained
for
1 to 2 seconds.
With a manual gearbox, in the event
of the automatic emergency braking
bringing the vehicle to a complete stop,
the engine may stall.
With an automatic gearbox, in the event
of the automatic emergency braking
bringing the vehicle to a complete stop,
keep the brake pedal pressed to stop
the vehicle moving off again.
If the radar and the camera have
confirmed the presence of a vehicle
or a pedestrian, this warning lamp
flashes once the function is acting on
the vehicle's brakes.
Important
: if operation of the
automatic emergency braking is
triggered, you should take back
control of your vehicle and brake
with the pedal to add to or finish the
automatic braking action.
The driver can take back control of the vehicle
at any time by sharply turning the steering
wheel and/or pressing the accelerator pedal.
The triggering of the braking may be
adjusted according to the driver's
driving actions (such as steering wheel
movements, actions on the accelerator
pedal, etc.).

Special features of the function
The speed of the vehicle must be between
3 mph (5 km/h) and 87 mph (140 km/h) when a
moving vehicle is detected.
The speed of the vehicle must not be higher
than 50 mph (80 km/h) when a stationary
vehicle is detected.
The speed of the vehicle must not be higher
than 37 mph (60 km/h) when a pedestrian is
detected.
The ESC system must not be faulty.
The ASR function must not be deactivated.
The seat belts of all occupants must be
fastened.
Driving at a steady speed on fairly straight
roads is required.
Following an impact, the function is put
out of service automatically, consult
a CITROËN dealer or a qualified
workshop to have the system checked.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to
avoid a collision, this system will complete the
braking, within the limits of the laws of physics.
This assistance will only be provided if you
press the brake pedal.
Deactivation / Activation
By default, the system is automatically
activated at every engine start.
The system can be deactivated or activated in
the vehicle settings menu in the screen. Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a message.

Assisted Lane Departure Warning System
Using a camera placed at the top of the windscreen to identify lane markings on the ground, this system corrects the trajectory of the vehicle while
alerting the driver if it detects a risk of involuntary crossing of a line.
This system is particularly useful on motor ways and main roads.This system is a driving aid which cannot,
in any circumstances, replace the need
for vigilance on the part of the driver.
The driver remains responsible for the
vehicle in all circumstances. The system
helps the driver only when there is a risk
of the vehicle involuntarily wandering
from the lane it is being driven on. It does
not manage the safe driving distance, the
speed of the vehicle or the brakes.
The driver must hold the steering wheel in
a way that allows control to be taken back
in circumstances where the system is not
able to intervene (where there are no lane
markings, for example).
It is necessary to observe the driving
regulations and take a break every two
hours.
Operation
Conditions for operation
The speed of the vehicle must be between 40
and 112 mph (65 and 180 km/h).
The carriageway must have at least one lane
marking (solid or broken) on the ground.
The driver must hold the wheel with both
hands.
The change of trajectory is not accompanied by
operation of the direction indicators.
The ESC system must be activated. Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected, it makes the correction to the
trajectory necessary to return the vehicle to its
initial path.
The driver will then notice a turning movement
of the steering wheel.
This warning lamp flashes during
trajectory correction.
If the driver wishes to maintain the
trajectory of the vehicle, they can
prevent the correction by keeping a firm
grip on the wheel (during an avoiding
manoeuvre, for example).
The correction is interrupted if the
direction indicators are operated.

Park Assist
This system provides active assistance with
parking. It detects a parking space then
operates the steering to park in the space.
It operates 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 manoeuvres
safe. It may be necessary to move for wards
and backwards more than once.During a manoeuvre, the steering
wheel turns quickly: do not hold the
steering wheel, do not place your
hands between the spokes of the
steering wheel and take care with
loose and bulky clothing (scarves, ties,
handbags...) - Risk of injury!
When Park Assist is activated, it
prevents a change to STOP mode of
Stop & Start. In STOP mode, activation
of Park Assist restarts the engine.
This manoeuvring assistance system
cannot, in any circumstances, replace
the need for vigilance on the part of the
driver.
The driver must remain in control of their
vehicle ensuring that the space remains
clear throughout the manoeuvre.
In some circumstances, the sensors may
not detect small obstacles located in
their blind spots.
The driver can take control at any time by
gripping the steering wheel. The Park Assist system provides assistance for
the following manoeuvres:
A.
E

ntry into a parallel parking space
B.
E

xit from a parallel parking space
C.
B

ay parkingThe Park Assist system takes control
of the power steering for a maximum
of 4 manoeuvre cycles. The function
is deactivated after these 4 cycles.
If you think that your vehicle is not
positioned correctly, you should then
take control of the steering to carry out
the manoeuvre.
The Park Assist system cannot work
with the engine off.

Electronic stability control (ESC) incorporating
the following systems:
-
a
nti-lock braking system (ABS) and
electronic brake force distribution (EBFD),
-

e
mergency braking assistance (EBA),
-

w
heel anti-slip regulation (ASR) or traction
control,
-

d
ynamic stability control (DSC).
Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
These systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards improved control on
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The EBFD manages the braking pressure
wheel by wheel.
Emergency braking assistance
(EBA)
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)
This 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.

Anti-slip regulation (ASR) / Dynamic stability control (DSC)
Operation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of a
problem of grip or trajectory.
Deactivation of the ASR
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR, so that the wheels can turn freely and
regain grip.
Reactivate the systems as soon as the level of
grip permits.This is indicated by flashing of this
warning lamp in the instrument panel.
F
I
n the Driving menu, select the " Driving
functions " tab, then " Traction control".
Deactivation is confirmed by a message.
The ASR system will no longer act on the
operation of the engine or on the brakes in the
event of an involuntary change of trajectory.Operating fault Reactivation of the ASR
The system is reactivated automatically every
time the ignition is switched back on or from
30 mph (50 km/h).
Below 30 mph (50 km/h), you can reactivate it
manually:
F

I
n the Driving menu, select the " Driving
functions " tab, then " Traction control".
Illumination of this warning lamp,
accompanied by an audible signal
and a message, indicates a fault with
these systems.
Contact a CITROËN dealer or a qualified
workshop to have the systems checked.
ASR / DSC
These systems offer even greater
safety during normal driving, but they
should not encourage the driver to take
extra risks or drive at excessive speed.
When traction deteriorates (rain, snow,
ice), the risks of loss of grip increase.
Therefore, for your safety, it is essential
that these systems are left active in all
conditions, and particularly in difficult
conditions.
The operation of these systems
is assured provided that the
manufacturer's recommendations
concerning the wheels (tyres and rims),
the braking components, the electronic
components and the CITROËN
network
fitting and repair procedures are
complied with.
To ensure the effectiveness of these
systems in winter conditions, it is
essential that the vehicle is fitted with
four snow tyres which will enable the
vehicle to retain neutral handling.
After an impact, have the systems
checked by a CITROËN dealer or a
qualified workshop.
