70two additional uses
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.
Also, the additional passenger compartment
heating system supplements the standard
system. Its operation may be independent of
the engine. Switching on of the heating may
be programmable.

driver.
dynamic stability control
( d S c )
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.

Impact resistance
Your vehicle has been designed to limit
the forces on the passenger compartment
as much as possible in the event of a
collision, the engine compartment adopts
a progressive deformation structure and
the front doors have been reinforced to
contribute to the rigidity of the whole.
Anti-theft protection
Your vehicle, in the van version, comprises
two zones with separate locking: the cab
and the load space.
Depending on the way in which it is used,
this function provides increased protection
both for your personal belongings and for
your merchandise.
An exterior protection alarm with anti-tilt
detection is available (as standard or as an
option) in certain countries.Details of these functions are given
in the "Ready to go - Front and rear
doors" section.

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 front passengers 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's front passenger airbag
cannot be deactivated: you must not install a
rearward facing child seat.

driving advice
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.
c

ooling: 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
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.
r

ear parking sensors: the system is
deactivated while the vehicle is towing with a
genuine CITROËN towbar fitted.
Refer to the "Technical data -
Identification markings" section.
