Cancelling the programming Press this button briefly to clear
the programmed start time.
The display lighting and the
pre-selection number (e.g. 1) are
switched off. 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 is supplied by the
vehicle's fuel tank.
Ensure that the fuel gauge indicator light is
not at reserve.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire.
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 system is fitted with
a temperature limiter which cuts off the
combustion in the event of overheating due
to a lack of coolant.
Top up the coolant, then press the
programme selection control before
switching the heating on again. Have the additional heating system
checked at least once a year at the
beginning of winter. Maintenance and
repairs should only be carried out by a
CITROËN dealer.
Use recommended replacement parts only.
Recalling one of the pre-selected
start times Press this button as many times
as necessary until the number
corresponding to the required
pre-selected start time (e.g. 2)
appears.
After ten seconds, the time is cleared but
remains stored for as long as the number
(e.g. 2) and the display remain lit.
Switching off the heating
Press this button.
The heating cycle indicator light
and the display are switched off. Two different types of equipment
The additional heating is autonomous and
programmable. Before you enter the vehicle,
it gradually increases the temperature of the
engine to make starting easier.
This also facilitates passenger compartment
heating, de-icing and demisting.
The additional passenger compartment
heating system supplements the
standard equipment. Its operation may be
independent of the engine.
Switching on of the heating may be
programmable.

ACCESSORIES
Towing a trailer

Cooling: 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 (see the "Identification
features" section of chapter 9) and of
the trailer, observing the recommended
pressure.
Towbar
We recommend the use of original
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.
If this equipment is not fitted by a
CITROËN dealer, it is imperative that it is
fitted using the electrical pre-equipment
installed at the rear of the vehicle and
in accordance with the manufacturer ’s
instructions.
Good practice
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning light comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.
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.

Rear parking assistance: the assistance
does not function while the vehicle is towing.

LEVELS
These regular maintenance operations
will keep your vehicle in good running
order. Consult the instructions at CITROËN
dealerships or in the servicing booklet
enclosed in the handbook pack. To maintain the reliability of engines and
emission control systems, the use of
additives in engine oil is prohibited.
Changing the brake fluid
The brake fluid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fluids recommended by the
manufacturer, which fulfil DOT4 standards.
The level must be between the
MIN and

MAX marks on the reservoir.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer as soon as possible.
If you have to remove/refit the engine
style cover, handle it with care to avoid
damaging the fixing clips.
Dipstick
There are two marks on
the dipstick:
Oil change
It is imperative that this is carried out at the
intervals specified and the viscosity grade of
the oil selected must fulfil the requirements
in accordance with the manufacturer's
servicing schedule. Consult the instructions
at CITROËN dealerships.
Remove the dipstick before filling.
Check the level after filling (never exceed
the maximum mark).
Screw the cap back onto the sump before
closing the bonnet.
Viscosity selection
In all cases, the oil selected must meet the
manufacturer's requirements.
Warning lights
Checking by means of the warning
lights on the instrument panel is
described in chapter 2, refer to the
"Instruments and controls" section.

A = maximum
If you fill past this mark,
contact a CITROËN dealer.

B = minimum
Never allow the level to fall
below this mark.
Oil level
Check the level regularly and top up
between changes. The maximum
consumption is 0.5 l per 600 miles
(1 000 km). Check the level with the vehicle
level, engine cold, using the dipstick. Levels

CHECKS
Cooling system
Only use the fluid recommended by the
manufacturer. Otherwise, you risk seriously
damaging your engine. When the engine
is warm, the temperature of the coolant is
controlled by the engine fan. As this fan can
operate with the ignition key removed and
because the cooling system is pressurised,
wait for at least one hour after the engine
has stopped before carrying out any work.
Slacken the cap by 1/4 of a turn to release
the pressure to prevent any risk of scalding.
When the pressure has dropped, remove the
cap and top up the level with coolant.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer as soon as possible.
Power steering fluid level
The vehicle must be parked on level ground
with the engine cold. Unscrew the cap
integrated with the gauge and check the
level which must be between the MIN and

MAX marks.
Used oil
Avoid prolonged contact of used oil with the
skin.
Brake fluid is harmful to health and very
corrosive.
Do not dispose of used oil, brake fluid or
coolant into drains or into the ground but
into the containers dedicated to this use at
CITROËN dealerships.
Topping up
The level must be between the MIN and

MAX marks on the expansion bottle. If
more than 1 litre of fluid is required to top
up the level, have the system checked by a
CITROËN dealer.
Windscreen wash and headlamp
wash level
For best quality cleaning and to prevent
freezing, this fluid must not be topped up or
replaced with water.
Capacity of the reservoir: approximately
5.5 litres. Levels
