START mode is invoked automatically when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the speed of the vehicle exceeds 15 mph
(25 km/h) with a manual gearbox (2 mph
(3 km/h) with the Blue HDi 120 version),
7 mph (11 km/h) with an electronic gearbox
and 2 mph (3 km/h) with an automatic
gearbox.

- the electric parking brake is being applied,

- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed for control of a system.


Special cases: START invoked
automatically

If the system has been deactivated
in STOP mode, the engine restarts
immediately.
At any time, press the "ECO OFF"
switch to
deactivate the system.
This is confirmed by the switch warning lamp
coming on accompanied by a message in the
screen.

Deactivation

In this case the "ECO"
warning lamp
flashes for a few seconds, then goes
off.

This operation is per fectly normal.

129Driving

The system is reactivated automatically
at every new start using the START/
STOP button.



Reactivation

Press the "ECO OFF"
switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and a
message in the screen.

Operating fault

In the event of a fault with the system, the
"ECO OFF"
switch warning lamp flashes then
comes on continuously.
Have it checked by a CITROËN dealer or a
qualified workshop.
In the event of a fault in STOP mode, the vehicle
may stall.
All of the instrument panel warning lamps come
on.
Depending on version, an alert message may also
be displayed, asking you to place the gear lever in
position N
and put your foot on the brake pedal.
It is then necessary to switch off the ignition and
start the engine again using the "START/STOP"
button.
Before doing anything under the
bonnet, deactivate the Stop & Start
system to avoid any risk of injury
resulting from automatic operation of
START mode.
This system requires a 12 V battery with a
special specification and technology (reference
numbers available from CITROËN dealers).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction of the
system.
For charging, use a 12 V charger and do not
reverse the polarity.

Maintenance


The Stop & Start system makes use of
advanced technology. For any work on
the system go to a qualified workshop
with the skills and equipment required,
which a CITROËN dealer is able to
provide.

147Visibility

Lighting left on audible
signal
An audible signal when a front door
is opened warns the driver that the
vehicle's exterior lighting is on, with the
ignition off and in manual lighting mode.
In this case, switching off the lighting
stops the audible signal.
With the ignition off, if the dipped
headlamps remain on, the vehicle goes
into "ECO" mode to avoid discharging
the battery.
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.

The daytime running
lamps can be activated
and deactivated via the
configuration menu.

The lighting goes off when you switch
off the ignition, but you can always
switch it on again using the lighting
control stalk.











Daytime running lamps
(LEDs)
They come on when the engine is started.
Depending on the country of sale or where
required by regulations, they are used for:


- daytime running lamps in day mode and
sidelamps in night mode (they are brighter
when daytime running lamps),
or


- sidelamps in day and night mode.

12 V battery







The presence of this label, in particular
with the Stop & Start system, indicates
the use of a 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. The battery is located under the bonnet.
To gain access to it:



open the bonnet using the interior release
lever, then the exterior safety catch,


remove the plastic cover on
the (+) terminal,


if necessary, unclip the fusebox to remove
the battery.

Procedure for starting the engine using another battery or charging a discharged battery.

223Practical information

After refitting the battery, the Stop &
Start system will only be active after a
continuous period of immobilisation of the
vehicle, a period which depends on the
climatic conditions and the state of charge
of the battery (up to about 8 hours).
With Stop & Start, the battery does not
have to be disconnected for charging.

cable to the negative terminal (-) of the
slave battery B
(or earth point on the other
vehicle).


Connect the other end of the green or black
cable to the earth point C
on the broken
down vehicle (or on the engine mounting).


Start the engine of the vehicle with the
good battery and leave it running for a
few minutes.

Operate the starter on the broken down
vehicle and let the engine run
If the engine does not star t straight away,
switch off the ignition and wait a few
moments before trying again.



are clean. If they are covered with sulphate
(whitish or greenish deposit), remove them
and clean them.













Charging the battery using
a battery charger
When your vehicle's battery is discharged,
the engine can be started using a slave battery
(external or on another vehicle) and jump lead
cables.

The batteries contain harmful substances
such as sulphuric acid and lead. They
must be disposed of in accordance
with regulations and must not, in any
circumstances, be discarded with household
waste.
Take used remote control batteries and
vehicle batteries to a special collection point.


It is advisable to disconnect the battery
if the vehicle is to be left unused for
more than one month.









Do not push the vehicle to start the
engine if you have an electronic or
automatic gearbox.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area and
away from naked flames and sources
of sparks, so as to avoid the risk of
explosion or fire.
Do not try to charge a frozen battery;
the battery must first be thawed out to
avoid the risk of explosion. If the battery
has been frozen, before charging have
it checked by a CITROËN dealer or a
qualified workshop who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
corrosive acid.
Do not reverse the polarity and use only
a 12 V charger.
Do not disconnect the terminals while
the engine is running.
Do not charge the batteries without
disconnecting the terminals first.
Wash your hands after wards.








Before disconnecting the battery

Wait 2 minutes after switching off the ignition
before disconnecting the battery.
Close the windows and the doors before
disconnecting the battery.


Following reconnection of the
battery
Following reconnection of the battery, switch on
the ignition and wait 1 minute before starting to
permit initialisation of the electronic systems.
However, if problems remain following this
operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the corresponding section,
you must yourself reinitialise (depending on
version):


- the remote control key,

- the electric blind(s),

- ...


Some functions are not available if the
battery is not sufficiently charged.

225Practical information
