5. Air outlets to the front footwells. Using the ventilation and air
conditioning system
F

T
o ensure that the air is distributed
evenly, keep the external air intake
grilles at the base of the windscreen,
the nozzles, the vents, the air outlets
and the air extractor in the boot free
from obstructions.
F
D
o not cover the sunshine sensor,
located on the dashboard; this is used
for regulation of the automatic air
conditioning system.
F
O
perate the air conditioning system for
at least 5 to 10 minutes once or twice
a month to keep it in per fect working
o r d e r.
F
I
f the system does not produce cold air,
switch it off and contact a CITROËN
dealer or a qualified workshop.
When towing the maximum load on
a
steep gradient in high temperatures,
switching off the air conditioning increases
the available engine power and so
improves the towing ability. Avoid driving for too long with the
ventilation off and prolonged operation
with recirculation of interior air – risk of
misting and deterioration of the air quality!
If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
The condensation created by the air
conditioning results in a discharge of water
under the vehicle which is per fectly normal.
Ease of use and comfort

66
"Normal ": offers the best compromise between
a comfortable temperature and quiet operation
(default setting).
" Fast ": provides strong and effective air flow.
Use the " Normal" or "Fast" modes to ensure
the comfort of passengers in the rear seats.
This setting is associated with automatic mode
only. However, on deactivation of AUTO mode,
the indicator lamp for the last setting remains
on.
Changing the setting does not reactivate AUTO
mode if this was deactivated.
In cold weather with the engine cold, the
air flow is increased gradually until the
comfort setting has been reached, in order
to limit the delivery of cold air into the
passenger compartment.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort setting requested, there
is no need to alter the value displayed
to more quickly reach the required level
of comfort. The system automatically
corrects the temperature difference as
quickly as possible.Automatic visibility
programme
For more information on the button 1
"Automatic Visibility Programme ", refer to
the section " Front demist – defrost ".
"Air Quality System " (AQS)
function
Using a pollution sensor, this function
a utomatically activates recirculation of the
interior air once a
certain level of polluting
substances in the exterior air is detected.
When the air quality returns to a
satisfactory
level, recirculation of interior air is automatically
deactivated.
This function is not designed to detect
unpleasant odours.
Recirculation is automatically activated when
the front screenwash is used or when reverse
gear is engaged.
The function does not operate if the exterior
temperature is below 5°C, to avoid the risk of
misting of the windscreen and side windows.
To activate or deactivate the function, go
to the secondary page by using button 11
" OPTIONS ", then press button 15 .
Manual control
You can manually adjust one or more of these
functions, while retaining automatic control of
the other functions by the system:

Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal and upright sitting
position.
Wear a
correctly adjusted seat belt.
Do not leave anything between the
occupants and the airbags (a child, pet,
object, etc.), nor fix or attach anything
close to or in the way of the airbag release
trajectory; this could cause injuries during
their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly
around the airbags.
After an accident or if the vehicle has
been stolen, have the airbag systems
checked.
All work on the airbag systems must only
be carried out by a
CITROËN dealer or
a


qualified workshop.
Even if all of the precautions mentioned
are obser ved, a risk of injury or of minor
burns to the head, chest or arms cannot
be ruled out when an airbag is deployed.
The bag inflates almost instantly (within
a
few milliseconds) then deflates within
the same time discharging the hot gas via
openings provided for this purpose. Front airbags
Do not drive holding the steering wheel
by its spokes or resting your hands on the
centre part of the wheel.
Passengers must not place their feet on
the dashboard.
Do not smoke as deployment of the
airbags can cause burns or the risk of
injury from a
cigarette or pipe.
Never remove or pierce the steering wheel
or hit it violently.
Do not fix or attach anything to the
steering wheel or dashboard, as this
could cause injuries when the airbags are
deployed.
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed. Lateral airbags
Use only approved covers on the seats,
compatible with the deployment of the
lateral airbags. For information on the
range of seat covers suitable for your
vehicle, contact the CITROËN network.
Do not fix or attach anything to the seat
backrests (clothes, etc.), as this could
cause injuries to the thorax or arm when
the lateral airbag is deployed.
Do not sit with the upper part of the body
any nearer to the door than necessary.
The vehicle's front door panels include
side impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior
trim could compromise the operation of
these sensors – risk of malfunction of the
lateral airbags!
Such work must only be done by
a
CITROËN dealer or a qualified
workshop.

Safety

117
In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load
by 10% per 1,000
metres of altitude; the
decreased air density at altitude reduces
engine performance.
New vehicle: do not pull a
trailer
before having driven at least 620
miles
(1,000


kilometres). If the outside temperature is high, let the
engine idle for 1
to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a
CITROËN dealer or a qualified
workshop.
F

D
istribute the load in the trailer so that the
heaviest items are as close as possible to
the axle and the nose weight (at the point
where it joins your vehicle) approaches the
maximum permitted without exceeding it.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical signalling on the trailer and the headlamp beam height of your
vehicle.
If a
genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the
audible signal.
When driving
Cooling
Towing a trailer uphill increases the
t emperature of the coolant. The maximum
towable load depends on the gradient and the
exterior temperature. The cooling capacity of
the fan does not increase with engine speed.
F

R
educe speed and lower the engine speed,
so as to limit the heating-up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as
soon as possible.
Brakes
Braking distances are increased when towing
a trailer. To avoid overheating of the brakes, the
use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the
wind that the vehicle will have.
