Deactivation
To give precedence to the control
of the temperature in the passenger
compartment, the Stop & Start
system should be deactivated to
allow continuous operation of the air
conditioning. The system is reactivated automatically
at every new start using the key.
At any time, press the "S - OFF" switch to
deactivate the system.
This is confirmed by the switch warning lamp
coming on accompanied by a message in
the instrument panel screen.
If the system has been deactivated
in STOP mode, the engine restarts
immediately. Operating fault Maintenance
In the event of a fault with
the system, the Stop & Start
system is deactivated and the
service warning lamp comes on,
accompanied by a message in the
instrument panel screen
Have it checked by a CITROËN dealer.
In the event of an operating fault with STOP
mode, it is possible to restart the engine by
depressing the clutch pedal fully and putting
the gear lever into neutral. Before working under the bonnet, you
must switch off the ignition with the
key to avoid any risk of injury resulting from
automatic operation of START mode.
This system requires a specific battery
with a special specification and technology
(reference numbers available from
CITROËN dealers).
Fitting a battery not listed by
CITROËN introduces the risk of malfunction
of the system.
The Stop & Start system makes use
of advanced technology. Specialist
knowledge is needed for any work on the
system, which can only be assured by
CITROËN dealers.
Reactivation
Press the
"S - OFF" switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and a
message in the instrument panel screen.

Driving safely
Emergency braking assistance *
System which, in an emergency, enables
you to reach the optimum braking pressure
more quickly, thus reducing the stopping
distance. The emergency braking assistance
is an integral part of the ESP system
Activation
It is brought into play 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.
Good practice
This system cannot be deactivated by the
driver.
* Depending on country of sale.
TRAJECTORY CONTROL SYSTEMS
Electronic stability programme (ESP)
The electronic stability programme 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
The ESP system is activated automatically
each time the vehicle is started and cannot
be deactivated.
It comes into operation in the event of a grip
or trajectory problem.
Illumination of this warning lamp
and the warning lamp in the

"ASR OFF" button, accompanied
by a message in the instrument
panel screen, indicates a fault with the ESP
system, which is deactivated automatically.
Have it checked by a CITROËN dealer. Anti-slip regulation (ASR) and engine
control (MSR)
Anti-slip regulation (also known as traction
control) optimises traction, avoiding wheel
spin by acting on the brakes of the driving
wheels and the engine.
Engine control is an integral part of the ASR
system and intervenes when a sudden gear
change is made or of one of the driving
wheels looses grip, by reducing engine
torque to avoid loss of stability of the vehicle.
Activation
These systems are activated automatically
every time the vehicle is started.
In the event of a problem od adhesion or
trajectory, these systems come into play.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow,
on soft ground...), it may be advisable to
deactivate the ASR system, so that the
wheels can spin freely and regain grip.

 Press the "ASR OFF" button, located in
the middle of the dashboard.
If the button's warning lamp comes
on, accompained by a message in the
instrument panel screen, this indicates that
the ASR system is deactivated.
This is indicated by flashing of this
warning lamp in the instrument
panel.

SAFETY
Seat belts
FRONT SEAT BELTS
The front seats are fitted with pre-tensioners
and force limiters.
Fastening
Pull the strap, then insert the tongue into the
buckle.
Check that the seat belt is fastened correctly
by pulling the strap.
The lap belt must be positioned as low as
possible on the pelvis. The chest belt must
pass over the hollow of the shoulder. Inertia reel seat belts
These are fitted with a device which locks
automatically in the event of a collision or
emergency braking.
Safety in the event of a front impact has
been improved by the introduction of
pretensioning and force limiting seat belts.
Depending on the seriousness of the
impact, the pretensioning system instantly
tightens the seat belt against the body of the
occupant.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of the
seat belt against the body of the occupant in
the event of an accident. Driver's seat belt not fastened warning
lamp
When the vehicle is started, this
warning lamp comes on if the
driver has not fastened their seat
belt.
REAR SEAT BELTS (COMBI)
The 3-seat bench is fitted with three-point
inertia reel seat belts with force limiter.
The centre seat has a seat belt guide and
inertia reel, integrated with the seat back.
When a seat belt is not in use, you can
store its buckle in the housing provided
in the bench seat cushion.
If the driver's seat belt is unfastened,
the START mode of Stop & Start will
not be invoked. The engine can only be
restarted using the ignition key.

ACCESSORIES
Towing a trailer
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this case,
automatic cutting off of the air conditioning
allows the engine power to be saved.
If the coolant temperature
warning light comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.

Tyres: check the tyre pressures of the
towing vehicle (see the "Identification
markings" section of chapter 7) and of
the trailer, observing the recommended
pressures.

Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.

ABS: the system only controls the vehicle,
not the trailer.

Rear parking sensors: the sensors
will be deactivated automatically
when an genuine CITROËN towbar is used
(see the "Rear parking sensors" section of
chapter 3). Towbar
We recommend the use of original
CITROËN towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle, and that
the fitting of this equipment is entrusted to a
CITROËN dealer.
If this equipment is not fitted by a CITROËN
dealer, it is essential that it is fitted using
the electrical pre-equipment located at
the rear of the vehicle and following the
manufacturer's instructions.
The operation of the rear parking sensors is
deactivated automatically when the trailer
cable connector is inserted in the towbar
socket.
When the trailer cable is removed, the rear
parking sensors are re-activated.

Distribution of loads
Distribute the load in the trailer so that the
heaviest objects are as close as possible
to the axle and the nose weight is close to
the maximum authorised without, however,
exceeding it. The air density decreases with
altitude, so reducing the performance of
the engine. The maximum towed load must
be reduced by 10 % for each 1 000 metres
of altitude. Refer to the "Technical data"
chapter for details of the weights and
towed loads applicable to your vehicle
and also to the administrative documents
(V5 registration document, ...).

Battery Batteries contain harmful substances
such as sulphuric acid and lead. They
must be disposed of in accordance with the
law and must not, in any circumstances be
discarded with household waste.
Take used batteries to an authorised waste
disposal site.
It is advisable to disconnect the battery
if the vehicle is not to be used for a
period of more than one month. To do
this on models with Stop & Start:
- press the release button E to disconnect
connector F ,
- disconnect connector F of check sensor G .
Never remove the check sensor G from the
metallic point H , except when replacing the
battery.
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification, for
which the involvement of a CITROËN dealer
is required when replacing or disconnecting
the battery.
Failure to observe this recommendation may
cause premature wear of the battery.
After refitting the battery, the Stop &
Start system will only be active after
a continuous period of immobilisation of
the vehicle, a period which depends on the
climatic conditions and the state of charge of
the battery (up to about 8 hours). Before charging
The charging operation must be carried out in
a ventilated area away from naked fl ames or
any possible sources of sparks to eliminate the
risks of explosion and fi re.
Do not attempt to charge a frozen battery: it
must fi rst be thawed to eliminate the risks of
explosion. If the battery has frozen, before
charging it have it checked by a specialist who
will check that the internal components have
not been damaged and that the container is
not cracked, which could mean that there is a
risk of a leak of toxic and corrosive acid.
Before disconnecting
Never disconnect a terminal when the
engine is running.
Before disconnecting the battery, you must wait
for 2 minutes after switching off the ignition.
Close the windows and doors before
disconnecting the battery. After reconnecting
After every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If difficulties are
experienced after this, contact a CITROËN
dealer.
If the battery has been disconnected
for some time, it may be necessary to
reinitialise the following functions:
- the display parameters (date, time,
language, distance and temperature
units),
- the radio stations,
- the central locking.
Some settings are cleared and must be
reprogrammed. Contact a CITROËN dealer.
