69
Have the additional heating checked at
least once a year at the beginning of
winter. Maintenance and repairs should only
be carried out by a CITROËN dealer or a
qualified workshop.
Use only genuine replacement parts.
Switching off the heating
In the case of deferred operation, the
heating stops at the end of the programmed
period.
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 switches off when the
battery voltage is low, so as to allow engine
starting.
The additional heating is supplied by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion. 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 is fitted with
a temperature limiter which cuts off
the combustion in the event of engine
overheating due to a lack of coolant. Check
the level and if necessary top-up following
the advice given in the "Checks - Levels"
section. Then press the programme
selection button before switching the heating
on again.

the
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.

when the system is brought into operation.
If the speed of the vehicle exceeds 18

mph
(30 km/h), the system is automatically
deactivated, but the indicator lamp in the
button stays on.
The system reactivates automatically as
soon as the speed of the vehicle drops
below 18 mph (30 km/h).
For the system to operate, the slope
must be steeper than 8%.
Do not use the system with the gearbox in
neutral.
Engage an appropriate gear for the speed of
the vehicle, to avoid the engine stalling.

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

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.
