F Press button 5 to activate/deactivate the air
conditioning system.
When the indicator lamp is on, the air
conditioning function is activated.
The air conditioning does not operate when
the air flow adjustment is inhibited.
To obtain cool air more quickly, you can
use recirculation of the interior air for a
few
moments. Then return to the intake of
exterior air.
Switching off the air conditioning may result
in some discomfort (humidity, condensation).
Automatic comfort
programme
F Press the " AUTO" button 6 to activate or
deactivate the automatic mode of the air
conditioning system.
The air conditioning system operates
automatically: the system manages the
temperature, air flow and air distribution in the
passenger compartment in an optimum way
according to the comfort level you have selected.
F Go to the secondary page by pressing button 8 " OPTIONS " to adjust the automatic
comfort programme by choosing one of the
available settings. F

T
o change the current setting,
press the button several times
in succession to access the
desired mode:
" Soft ": provides soft and quiet operation by
limiting air flow.
" Normal ": offers the best compromise between
a

comfortable temperature and quiet operation
(default setting).
" Fast ": provides strong and effective air flow.
This setting is associated with AUTO mode
only. However, on deactivation of AUTO mode,
the last selected setting remains.
Changing the setting does not reactivate AUTO
mode if 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 in
order to reach more quickly the required
level of comfort. The system automatically
corrects the temperature difference as
quickly as possible. You can always choose to change a
setting
manually. In this case, the automatic comfort
programme is deactivated.

You can make use of the residual heat in the
engine to warm the passenger compartment
using the temperature setting buttons.
Recirculation of interior air
The intake of exterior air helps avoid and
eliminate misting of the windscreen and side
windows.
Recirculation of the interior air isolates the
passenger compartment from exterior odours
and fumes.
When required, this function can also be
used to speed up the heating or cooling of
the passenger compartment.

Lighting control stalk
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal sur face of the
glass of the headlamps and rear lamps is
normal; it disappears after the lamps have
been on for a few minutes.
If one or more lamps fails, a message
asks you to check the lamp or lamps
concerned.
Driving abroad
Halogen headlamps
If planning to use your vehicle in a
country
that drives on the other side of the road,
the dipped beam headlamps must be
adjusted to avoid dazzling on-coming
drivers. Contact a
CITROËN dealer or
qualified workshop.
Xenon headlamps
The design of the dipped beam headlamps
allows, without modification, driving in
a
country that drives on the other side
of the road to the country in which your
vehicle was sold.

Driving advice
Observe 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, taking 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.
Important!
Never drive with the parking brake applied
– Risk of overheating and damage to the
braking system!
As the exhaust system of your vehicle
is very hot, even several minutes after
switching off the engine, never park or run
the engine on inflammable sur faces (dry
grass, fallen leaves, etc.) – 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.
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. If you are obliged to drive on a
flooded road:
-
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 function,
-
d
rive as slowly as possible without stalling.
In all cases, do not 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 safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.

In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
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
approximately 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
adjustment , refer to the corresponding
section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
This electronic engine immobiliser locks the
engine management system a
few moments
after the ignition is switched off, and prevents
starting of the engine by anyone who does not
have the key.
In the event of a
malfunction, you are informed
by a
message in the instrument panel screen.
If this happens, your vehicle will not start;
contact a
CITROËN dealer if required.
