Ease of use and comfort

50
To avoid the risks of poisoning or
asphyxia, the additional heating must
not be used, even for short periods, in
a closed environment such as a garage or
workshop which are not equipped 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 fed by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when refuelling to avoid any risk of fire or
explosion!
The temperature near the heating
system must not exceed 120°C. A higher
temperature (e.g. when baking the
paint) could damage the components of
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 top up if necessary.
For more information on Checking levels ,
refer to the corresponding section.
Then press the programme selection
button before switching the heating on
again.Recommendations for ventilation and air conditioning
In order for these systems to be fully effective,
follow the operation and maintenance
guidelines below:
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 order.
F

E
nsure that the passenger compartment
filter is in good condition and replace
the filter elements periodically. We
recommend the use of a
combined
passenger compartment filter. Thanks to
its special active additive, it helps both to
purify the air breathed by the occupants
and to keep the passenger compartment
clean (reduction of allergic symptoms, bad
odours and greasy deposits). F
T o ensure correct operation of the
air conditioning system, you are also
advised to have it checked regularly as
recommended in the Maintenance and
Warranty Guide.
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.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d
o not drive for too long with the
ventilation switched off.
-

d
o not keep air recirculation set for an
extended period.
Ease of use and comfort

If after an extended stop in sunshine, the
interior temperature is very high, first 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.
Contains fluorinated greenhouse
gases R134A
Depending on model and country of
sale, the air conditioning system may
contain fluorinated greenhouse gases
R13 4A .
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
To maintain a
comfortable temperature
in the passenger compartment, you may
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.Front demist – defrost
These markings on the control panel
indicate the control positions for
rapid demisting or defrosting of the
windscreen and side windows.
With manual air
conditioning
F Put the air flow and distribution controls to the appropriately
marked position.
For faster and more effective demisting and
defrosting of the windscreen:
F

i

ncrease the air flow setting, F

m
ove the exterior air intake
control temporarily to air
recirculation.
With automatic air
conditioning
F Press this button, the indicator lamp comes on. The system manages the cooling, flow and
intake of air, 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.
Defrosting the rear screen
and door mirrors
F Press this button to activate
demisting/defrosting of the rear
screen and door mirrors. The
indicator lamp comes on.
This function switches off automatically to
prevent excessive energy consumption.
It is possible to stop the demisting/defrosting
operation before it is switched off automatically
by pressing this button again. The indicator
lamp goes off. Rear screen demisting/defrosting can only
operate when the engine is running.

Driving recommendations
Observe the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a
long journey, a break every two hours is
strongly recommended.
In difficult weather, drive smoothly, anticipate
the need to brake and increase the distance
from other vehicles.
Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a
risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4
minutes before driving.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle.
Important!
If you are obliged to drive through water:
- c heck that the depth of water does not
exceed 15
cm, taking account of waves that
might be generated by other users,
-

d
eactivate the Stop & Start system,
-

d
rive as slowly as possible without stalling.
Under no circumstances exceed 6
mph
(10


km/h),
-

d
o not stop and do not switch off the engine.
On leaving the flooded road, as soon as
circumstances 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.
Never drive with the parking brake
applied – risk of overheating and damage
to the braking system!
Do not park and do not run the engine
with the vehicle stationary, in areas where
substances and combustible materials
(dry grass, leaves, etc.) can come into
contact with the hot exhaust system – risk
of fire!
Never leave a vehicle unsuper vised with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P , depending on
the type of gearbox.
To assure the durability of your vehicle and
your safety, remember that certain precautions,
described hereafter, should be taken when
driving your vehicle:

Cooling
Towing a trailer on a slope increases the
t emperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a
trailer before having driven at
least 620
miles (1,000 kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
engine braking is recommended.
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 lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a
genuine CITROËN
towbar is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic immobiliser
device.
This device locks the engine supply system.
It activates automatically when the key is
removed from the ignition.
This warning lamp goes off after the
key has been recognised, the ignition is
switched on and the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key
and have the faulty key checked by
a
CITROËN dealer.
Note the number of the keys carefully; in
case of loss, inter vention by the CITROËN
dealer will be more efficient and quicker
if you present this number and the
confidential card.
When the ignition switch is turned on, a
dialogue is set up between the key and the
electronic immobiliser.
Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even when it
is in your pocket, may result in involuntary
unlocking of the doors.
The simultaneous use of other high
frequency equipment (mobile telephones,
domestic alarms, etc.), may inter fere
with the operation of the remote control
temporarily.
The remote control does not operate
while the key is in the ignition, even if the
ignition is off, except for reinitialisation.
