Instruments and controls

64comfort value adjustment
ring
The settings range between:
-

increasing the interior ambient air

temperature HI (High) which goes up to
to a maximum setting of 32,
-

cooling the interior ambient air

temperature LO (Low) which goes down
to a setting of 16.
Air distribution
A press illuminates the LED on the buttons
which distribute the air flow towards:
the windscreen and front side
window vents (demisting/
defrosting the windows),
the central and side vents (chest
and face),
the vents in the front and rear
areas (feet).
The combination of buttons permits
improvement of air distribution.
Air flow
Successive presses of this button
increase (+) or reduce (-) the
force of the air flow to the interior.
Intake of exterior air / r ecirculation of interior air
When the LED is on, the air
recirculates inside the passenger
compartment to prevent the entry of exterior
odours and smoke. This position should be
temporary.
When the ambient air comfort level has been
reached, pressing the button switches the
LED off and reopens the exterior air intake.
Pressing the A
ut
O
button also restores
the intake of exterior air. Returning to this
position permits renewal of the air in the
passenger compartment and demisting.
Pressing the A
ut
O
button again restores
the F
u
LL A ut
O
function.
rapid demisting / defrosting
Pressing this control permits
rapid clearing of the windows.
The LED is on.
The system manages the air conditioning,
the flow and intake of air, the defrosting
of the rear screen and provides optimum
distribution of the air to the windscreen and
front side windows.
If your vehicle is fitted with additional
heating, switch it off to ensure rapid and
effective demisting/defrosting.

The controls for this system, additional to
the standard cabin ventilation system, are
on the lower dashboard, to the left of the
steering wheel.
Air outlet
A press on this control activates
the extraction of air to the
outside; the LED comes on.
Press again to switch off.

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.

reactivation
The ASR system is reactivated automatically
every time the ignition is switched back on.
-

Press this button again to reactivate it

manually.
Operating fault If this warning lamp comes on,
accompanied by an audible signal
and a message in the instrument
panel screen, this indicates a fault
with the ASR system.
Have it checked by a CITROËN dealer or a
qualified workshop. Good practice
The DSC and ASR systems offer exceptional
safety in normal driving, but this should not
encourage the driver to take extra risks or
drive at high speed.
The correct operation of these systems
depend on observation of the manufacturer's
recommendations regarding the wheels
(tyres and rims), the braking components,
the electronic components and assembly
and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a qualified
workshop.Load inertia control
The true total weight of a commercial vehicle
can vary considerably depending on the load
carried. As a result, the centre of gravity of
the vehicle can move, both longitudinally
and in height.
All such variations have an effect on braking,
traction, the behaviour of the vehicle when
cornering and the tendency to overturn.
Load inertia control estimates the true
total weight of the vehicle by analysing its
behaviour under acceleration and braking.
This system then adapts the operation of
the DSC and ASR systems according to the
weight distribution in the vehicle. In critical
situations, your vehicle than remains more
securely on its intended trajectory.

Intelligent traction c ontrol
System to improve traction on slippery
surfaces (snow, black ice, mud...)
This system checks for situations of difficult
surface adhesion that could make it difficult
to move off or make progress.
In these situations, Intelligent
t
raction

c

ontrol takes over from the AS r system,
by transferring drive to the wheel with the
best grip on the ground to provide the best
traction and trajectory control. Switching on
On starting the vehicle, this system is
deactivated.
Press this button, located in the middle of
the dashboard, to activate the system; the
indicator lamp in the button comes on.
This system is active up to about 18 mph
(30 km/h).
Once the speed exceed 18 mph (30 km/h),
the system is deactivated automatically, but
the indicator lamp in the button stays on.
The system is reactivated automatically as
soon as the speed drops below 18 mph

(30 km/h). Switching off
Press this button, located in the middle of
the dashboard, to deactivate the system;

the indicator lamp in the button goes off and
the AS r system is active again.
Operating fault If a fault occurs with the intelligent
traction control system, this
warning lamp comes on.
Have the system checked by a CITROËN
dealer or a qualified workshop.
