HILL START ASSIST
This system (also called HHC - Hill Holder
Control), linked to the dynamic stability
control system, makes hill starts easier and
is activated in the following conditions:
- the vehicle must be stationary, engine running, foot on the brake,
- the gradient of the road must be steeper than 5%,
- uphill, the gearbox must be in neutral or in a gear other than reverse,
- downhill, reverse gear must be engaged.
The Hill Start Assist function is a driving
aid system. It is not an automatic vehicle
parking function or an automatic parking
brake. Operation
With the brake pedal and clutch pedal
pressed, from the time you release the brake
pedal you have approximately 2 seconds
before the vehicle starts to roll back and
without using the parking brake within which
to move off.
During the moving off phase, the function
is deactivated automatically, gradually
releasing the braking pressure. During
this phase, the characteristic noise of
mechanical release of the brakes may be
heard, indicating the imminent movement of
the vehicle.
Operating fault
If a malfunction of the system
occurs, this warning lamp comes
on accompanied by an audible
signal and confi rmed by a message
in the screen. Have the system checked by at
a CITROËN dealer or a qualifi ed workshop. Hill start assist is deactivated in the following
situations:
- when the clutch pedal is released,
- when the parking brake is applied,
- when the engine is switched off,
- when the engine stalls.

mode, it is possible to restart the engine by
depressing the clutch pedal fully and putting
the gear lever into neutral.
Maintenance
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 a
CITROËN dealer or a qualified workshop).
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. Refer to the "Quick help - Flat battery"
section.

Ventilation
Cancelling the programming
Press this button briefly to clear
the programmed start time.
The screen illumination and the
pre-selection number (e.g. 1) are
switched off.
Good practice
To avoid any risk of poisoning or
asphyxiation, the additional heating must
not be used, even for short periods, in
an enclosed space such as a garage or
workshop which is not fitted with an exhaust
gas extraction system.
The additional heating is supplied by the
vehicle's fuel tank.
Ensure that the fuel gauge indicator lamp is
not at reserve.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire.
The temperature near the heater must not
exceed 120 °C. A temperature higher than
this (for example in the case of painting in
an oven) could damage the components of
the electronic circuits.
The additional heating system is fitted with
a temperature limiter which cuts off the
combustion in the event of overheating due
to a lack of coolant.
Top up the coolant, then press the
programme selection control before
switching the heating on again. Have the additional heating system
checked at least once a year at the
beginning of winter. Maintenance and
repairs should only be carried out by a
CITROËN dealer.
Use only genuine replacement parts.
Recalling one of the pre-selected start times
Press this button as many times
as necessary until the number
corresponding to the required
pre-selected start time (e.g. 2)
appears.
After ten seconds, the time is cleared but
remains stored for as long as the number
(e.g. 2) and the screen remain on.
Switching off the heating
Press this button.
The heating cycle indicator lamp
and the screen are switched off.
Two different types of equipment
The additional heating is separate and
programmable. Before you enter the vehicle,
it gradually increases the temperature of the
engine to make starting easier.
This also facilitates passenger compartment
heating, demisting and defrosting.
The additional passenger compartment
heating system supplements the
standard equipment. Its operation may be
independent of the engine.
Switching on of the heating may be
programmable.

Driving safely
TRAJECTORY CONTROL SYSTEMS
Switching off
This system cannot be deactivated by
the driver.
Dynamic stability control (DSC)
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.
With the DSC system, maintain course
without trying to countersteer.
Operation
The DSC system is activated automatically
each time the vehicle is started. Operating fault
Illumination of this warning lamp,
accompanied by an audible signal
and confirmed by a message
in the instrument panel screen,
indicates a fault with the DSC system.
Have it checked by a CITROËN dealer or a
qualified workshop. Operation
This system is activated automatically every
time the vehicle is started.
In the event of a problem of adhesion or
trajectory, this system comes into play.
Switching off
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 this button, located in the
middle of the dashboard, to deactivate
the system.
Anti-slip regulation (ASR)
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.
If the button's warning lamp comes
on, accompanied by a message in the
instrument panel screen, this indicates that
the ASR system is deactivated.
It comes into operation in the
event of a grip or trajectory
problem.
This is indicated by flashing of this warning
lamp in the instrument panel.

movement, ensuring that it does not twist.
Secure the buckle in its housing.
Check that the seat belt is fastened securely
and that the automatic locking system is
operating correctly by pulling the strap
rapidly.
Unfastening
Press the "red" button on the buckle
housing, the seat belt rolls up automatically
but you are advised to guide it. As a safety precaution, these
operations should not be carried out
while the vehicle is moving.
Driver's seat belt not fastened warning lamp
CREW CAB
Each rear seat is fitted with a three-point
inertia reel seat belt.
Use the seat belt to restrain one person only
per seat.
If the driver's seat belt is unfastened,
START mode of Stop & Start will not be
invoked. Engine restarting is only possible
with the ignition key. When the vehicle is started, this warning
lamp comes on if the driver has not fastened
their seat belt.

106
Airbags
Deactivating the passenger's front airbag
When OFF is selected, the passenger's front
airbag will not be triggered in the event of an
impact.
As soon as the child seat is removed, select ON to
re-activate the airbag and thus ensure the safety
of your passenger in the event of an impact. Lateral airbags and curtain airbags
If your vehicle is fitted with lateral airbags,
these are fitted to the front seat backs on
the door side.
The curtain airbags are fitted to the door
pillars and the upper part of the passenger
compartment, in the roof over the front cab
seats.
They inflate between the occupant and the
glazed area.
They are deployed independently of each
other depending on which side the collision
occurs.
To ensure the safety of your child, it is
essential to deactivate the passenger's
front airbag when you install a rearward
facing child seat on the front passenger
seat. Otherwise, the child would risk being
killed or seriously injured if the airbag were
to inflate.
If your vehicle is not fitted with this facility:
do not install a rearward facing child seat. Deactivation check
This is confirmed by the
illumination of this warning lamp,
accompanied by a message in
the display screen, every time the
engine is started.
Operating fault If this warning lamp comes on,
contact a CITROËN dealer to
have the vehicle checked.
Refer to the "Technology on board -
Vehicle configuration" section.
The setting is made using the "
MODE "
button: in the "Passenger airbag" menu,
select " OFF ".

Transport solutions
ACCESSORIES
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.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.
Cooling: towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature. Tyres: check the tyre pressures of the
towing vehicle and of the trailer, observing
the recommended pressures.
Fitting a towbar
We recommend the use of genuine
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.
These genuine towbars are compatible with
the operation of the rear parking sensors
and the reversing camera, if fitted to your
vehicle.
If this equipment is not fitted by a CITROËN
dealer, it must be fitted in line with the
manufacturer's instructions.
Good practice
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, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning lamp comes on, stop the
vehicle and switch off the engine
as soon as possible.
Refer to the "Checks - Levels and
checks" section.
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 system does not
operate while the vehicle is towing.
Refer to the "Technical data -
Identification markings" section.
