deactivation
At any time, press the "A - OFF" switch to
deactivate the system.
Illumination of the switch indicator lamp,

accompanied by a message in the
instrument panel screen, confirms that the
instruction has been registered.
If the system has been deactivated
in STOP mode, the engine restarts
immediately.
It is necessary to deactivate the Stop
&
Start system if you want to allow
continuous operation of the air conditioning.
The switch indicator lamp stays on.
reactivation
Press the "A - OFF" switch again.
The system is active again; the switch
indicator lamp going off and a message
in the instrument panel screen confirm
reactivation.
Operating fault
In the event of a fault with the
system, the Stop & Start system
is deactivated and this warning
lamp comes on, accompanied by
a message in the instrument panel
screen.
Have it checked by a CITROËN dealer or a
qualified workshop.
In the event of an operating fault with STOP
mode, it is possible to restart the engine by
depressing the clutch pedal fully and putting
the gear lever into neutral.
Maintenance
Before working under the bonnet, you
must switch off the ignition with the
key to avoid any risk of injury resulting from
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.
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. Refer to the "Quick help - Flat battery"
section.

of cold or snow to the upper part of the
underbonnet.
Located at the edge of each headlamp,
they are fitted to the front panel above the

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.
Brake disc wear
For any information on checking the brake
disc wear, contact a CITROËN dealer or a
qualified workshop.If this warning lamp comes on,
have the brake pad wear checked
by a CITROËN dealer or a
qualified workshop.
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 or a qualified workshop.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a CITROËN dealer or a qualified
workshop. These operations will keep your vehicle
in good running order. Ask for advice
from a CITROËN dealer or refer to the
manufacturer's service schedule included in
the handbook pack.
cHEcKS
Battery
At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.
Air filter and passenger
compartment filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are given in
the maintenance and warranty guide.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary.
Refer to the "Checks - Under the
bonnet" section.
Oil filter
Change the filter regularly, in accordance
with the manufacturer's service schedule.
Levels and checks

145
Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
In order to avoid damaging the
electrical units, we strongly advise you
not to use high pressure washing to clean
the engine compartment.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes. 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.
diesel fuel filter
The Diesel fuel filter is located under the
bonnet, close to the brake fluid reservoir.
If this warning lamp comes on, the
filter must be bled to remove water.
Y

ou can also bleed the fuel filter
regularly, every time the engine oil
is changed.
Bleeding water from the filter

Connect a transparent pipe to the head

of the bleed screw 1 .
-

Place the other end of the transparent

pipe in a recipient.
