Assist function is a driving comfort system.
It is not an automatic vehicle parking
function or an automatic parking brake. Operation
With the brake pedal and clutch pedal
pressed, from the time you release the brake
pedal you have approximately 2 seconds
before the vehicle starts to roll back and
without using the parking brake within which
to move off.
During the moving off phase, the function
is deactivated automatically, gradually
releasing the braking pressure. During
this phase, the characteristic noise of
mechanical release of the brakes may be
heard, indicating the imminent movement of
the vehicle.

automatic operation of START mode.

This system requires a specific battery
with a special specification and technology
(reference numbers available from a
CITROËN dealer or a qualified workshop).
Fitting a battery not listed by
CITROËN introduces the risk of malfunction
of the system.
Refer to part 8 in the "Battery" section.

The Stop & Start system makes use
of advanced technology. Specialist
knowledge is needed for any work on the
system, which can only be assured by
CITROËN dealers.

Ventilation


Cancelling the programming

Press this button briefly to clear
the programmed start time.
The screen illumination 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 lamp 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 only genuine replacement parts.


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 screen remain on.


Switching off the heating

Press this button.
The heating cycle indicator lamp
and the screen are switched off.


Two different types of equipment

The additional heating is separate 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, demisting and defrosting.
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.

SAFETY
Airbags
Deactivating the passenger airbag

Refer to the "MODE" section of
chapter 4, then on the "Passenger
airbag" menu, select OFF
. When OFF
is selected, the passenger airbag
will not be triggered in the event of an impact.
As soon as the child seat is removed,
select ON
to re-activate the airbag and thus
ensure the safety of your passenger in the
event of an impact.
Lateral airbags and curtain airbags

If your vehicle is fitted with lateral airbags,
these are fitted to the front seat backs on
the door side.
The curtain airbags are fitted to the door
pillars and the upper part of the passenger
compartment, in the roof over the front cab
seats.
They inflate between the occupant and
the glass.
They are deployed independently of each
other depending on which side the collision
occurs.
The airbag warning lamp on the
instrument panel remains on while
the passenger airbag is deactivated.
To ensure the safety of your child, it is
essential to deactivate the passenger airbag
when you install a rear-facing child seat on
the front passenger seat. Otherwise, the
child would risk being killed or seriously
injured if the airbag were to inflate.
If your vehicle is not fitted with this
equipment: do not install a rear-facing
child seat.
Deactivation check

This is confirmed by lighting of
this warning lamp each time the
engine is started.
If your vehicle is fitted
with this screen, the
check is accompanied by
a message.
Operating check
Confirmed by this indicator lamp.

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
markings" section of chapter 9) and of
the trailer, observing the recommended
pressures.
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 lamp 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 sensors:
the system does not
operate while the vehicle is towing.

Levels
LEVELS
These regular maintenance operations
will keep your vehicle in good running
order. Ask for advice at a CITROËN dealer
or consult 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. Ask for advice at at
CITROËN dealer.
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 lamps


Checking by means of the warning
lamps 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 litre per 600 miles
(1 000 km). Check the level with the vehicle
level, engine cold, using the dipstick.

Levels


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 (France) or to an
authorised waste disposal site.


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 plain water.
Capacity of the reservoir: approximately
5.5 litres.

Checks
CHECKS
Air filter and passenger compartment filter

A clogged passenger compartment fi lter may
reduce the performance of the air conditioning
system and generate undesirable odours. The
replacement intervals for these components
are indicated in the servicing booklet.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as often
if necessary, refer to the "Under the bonnet"
section of chapter 7.
Manual gearbox

Have the level checked in accordance with
the manufacturer's servicing schedule.
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the servicing booklet which
correspond to your vehicle's engine.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
In order to avoid damaging the electrical
units, high pressure washing to clean the
engine compartment is strictly prohibited.
Parking brake
Where the parking brake travel is too great
or there is a reduction in the performance
of the system, the parking brake should be
adjusted, even between services.
Have the system checked by a CITROËN
dealer. Bleeding the water contained inthe Diesel filter

If this warning lamp comes on,
bleed the filter, otherwise bleed
regularly each time the engine oil
is changed.
To drain the water out, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Leave open until
all of the water has been drained out. Then
tighten the bleed screw or the water sensor.
HDi engines use advanced technology. All
work requires a special qualification which is
guaranteed by a CITROËN dealer.
Battery

At the start of winter, have your battery
checked by a CITROËN dealer.

Brake pads

Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Unless there is a leak on the system, a drop
in the brake fluid level indicates that the
brake pads are worn.


Brake disc/drum wear status

For any information relating to checking
the brake disc/drum wear status, contact a
CITROËN dealer.
Oil filter

Change the filter regularly, in accordance
with the servicing schedule.






The presence of this label, in particular
with the Stop & Start system, indicates the
use of a specific 12 V lead-acid battery
with special technology and specification.
The involvement of a CITROËN dealer
or a qualified workshop is essential when
replacing or disconnecting the battery.
