STOP & START

The Stop & Start system puts the en-
gine temporarily into standby - STOP
mode - during stops in the traffi c (red
lights, traffi c jams, or other...). The en-
gine restarts automatically - START
mode - as soon as you want to move
off. The restart takes place instantly,
quickly and silently.
Perfect for urban use, the Stop & Start
system reduces fuel consumption and
exhaust emissions as well as the noise
level when stationary.

Operation


Going into engine STOP mode

The "ECO"
warning lamp comes on
in the instrument panel and the en-
gine goes into standby automatically:


- with a manual gearbox
, at speeds
below 12 mph (20 km/h), when you
put the gear lever into neutral and
release the clutch pedal, If your vehicle is fi tted with
the system, a time coun-
ter calculates the sum of
the periods in STOP mode
d uring a journey. It resets itself to zero
every time the ignition is switched on
with the key.

- with an electronic gearbox
, at a
speed below 5 mph (8 km/h), when
you press the brake pedal or put the
gear lever into position N
. With an electronic gearbox, for
your comfort during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such
as braking, power steering, for
example.
Special cases: STOP mode
unavailable
STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine start
using the key,

- the electric parking brake is applied
or being applied,

- the engine is needed to maintain a
comfortable temperature in the pas-
senger compartment,

- demisting is active,

- some special conditions (battery
charge, engine temperature, brak-
ing assistance, ambient tempera-
ture...) where the engine is needed
to assure control of a system.
In this case, the "ECO"
warn-
ing lamp fl ashes for a few sec-
onds, then goes off. Never refuel with the engine in
STOP mode; you must switch off
the ignition with the key.

This operation is perfectly normal.

Deactivation

Going into engine START mode
At any time, press the "ECO OFF"

switch to deactivate the system.
This is confi rmed by the switch warning
lamp coming on accompanied by the
display of a message.
Special cases: START invoked
automatically
If the system has been deacti-
vated in STOP mode, the engine
restarts immediately. The "ECO"
warning lamp goes
off and the engine starts auto-
matically:


- with a manual gearbox
, when you
fully
depress the clutch pedal,

- with an electronic gearbox
:


●
gear lever in position A
or M
, when
you release the brake pedal,

●
or gear lever in position N
and the
brake pedal released, when you
move the gear lever to position A

or M
,

●
or when you engage reverse
gear.

For safety reasons or to ensure smooth
operation, START mode is invoked au-
tomatically when:


- you open the driver's door,

- you unfasten the driver's seat belt,

- the speed of the vehicle exceeds
15 mph (25 km/h) with a manual
gearbox or 7 mph (11 km/h) with an
electronic gearbox,

- the electric parking brake is being
applied,

- some special conditions (battery
charge, engine temperature, brak-
ing assistance, ambient tempera-
ture...) where the engine is needed
to assure control of a system.
In this case the "ECO"
warning
lamp fl ashes for few seconds,
then goes off.
With a manual gearbox in STOP
mode, if a gear is engaged with-
out fully depressing the clutch
pedal, a warning lamp comes
on or an alert message is dis-
played asking you to depress
the clutch pedal to restart the
engine.



Reactivation

Press the "ECO OFF"
switch again.
The system is active again; this is con-
fi rmed by the switch warning lamp go-
ing off and the display of a message.
The system is reactivated auto-
matically at every new start us-
ing the key.
This operation is perfectly normal.

Maintenance

In the event of a malfunction with the sys-
tem, the "ECO OFF"
switch warning lamp
fl ashes, then comes on continuously.
Have it checked by a CITROËN dealer or
a qualifi ed workshop.


Operating fault

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 specifi c battery
with a special specifi cation and technol-
ogy (reference numbers available from
a CITROËN dealer or a qualifi ed work-
shop).
Fitting a battery not listed by
CITROËN introduces the risk of mal-
function of the system.
The Stop & Start system makes
use of advanced technology. All
work on this type of battery must
be done only by a CITROËN
dealer or a qualifi ed 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 put the gear lever
into position N
and put your foot
on the brake pedal.
It is then necessary to switch off
the ignition, then restart the en-
gine using the key.

CHECKS







Particle emission filter (Diesel)

The start of saturation of the particle
emissions fi lter is indicated by:


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an
audible signal and a message
that there is a risk of blockage
of the particle emissions fi lter.






The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and specifi -
cation. The involvement of a CITROËN
dealer or a qualifi ed workshop is essen-
tial when replacing or disconnecting the
battery. On a new vehicle, the fi rst op-
erations of regeneration of the
particle emissions fi lter may be
accompanied by the smell of
"burning", which is perfectly nor-
mal.
Following prolonged operation
of the vehicle at very low speed
or at idle, you may, in excep-
tional circumstances, notice the
emission of water vapour at the
exhaust on acceleration. This
does not affect the behaviour of
the vehicle or the environment. As soon as the traffi c conditions per-
mit, regenerate the fi lter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, refer to
the "Additive level" section.
Unless otherwise indicated, check
these components in accordance with
the maintenance and warranty guide
and according to your engine.
Otherwise, have them checked by a
CITROËN dealer or a qualifi ed work-
shop.





















Air filter and passenger compartment filter


Refer to the maintenance and
warranty guide for details of
the replacement intervals for
these components.
Depending on the environ-
ment (e.g. dusty atmosphere)
and the use of the vehicle
(e.g. city driving), replace
them twice as often if necessary
.
A clogged passenger compartment fi l-
ter may have an adverse effect on the
performance of the air conditioning sys-
tem and generate undesirable odours.















Oil filter

Replace the oil fi lter each time
the engine oil is changed.
Refer to the maintenance and
warranty guide for details of
the replacement interval for
this component.













12 V battery


The battery does not require
any maintenance.
However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "12 V battery" section for
details of the precautions to be taken
before disconnecting the battery and
following its reconnection.

11
PRACTICAL INFORMATION
213
When your vehicle's battery is dis-
charged, the engine can be started
using a slave battery (external or on
another vehicle) and jump lead cables.












Starting using another battery




12 V BATTERY

The battery is located under the bonnet.
For access to the (+) terminal:


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


raise the bonnet and secure it with
its stay,


lift the plastic cover for access to the
(+) terminal.


Access to the battery







The presence of this label, in par-
ticular with the Stop & Start sys-
tem, indicates the use of a 12 V
lead-acid battery with special
technology and specifi cation;
the involvement of a CITROËN
dealer or a qualifi ed workshop is
essential when replacing or dis-
connecting the battery.
Procedure for starting the engine us-
ing another battery or charging a dis-
charged battery.

After refi tting 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).
First check that the slave battery
has a nominal voltage of 12 V
and a capacity at least equal to
that of the discharged battery.
Do not try to start the engine by
connecting a battery charger.
Do not disconnect the (+) termi-
nal when the engine is running.
Before doing any work
Immobilise the vehicle: apply the
parking brake, put the gearbox
in neutral, then switch off the ig-
nition.
Check that all electrical equip-
ment is switched off.

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












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 bat-
teries and vehicle batteries to a
special collection point.



Disconnect the battery from the vehicle.



Follow the instructions for use pro-
vided by the manufacturer of the
charger.


Connect the battery starting with the
negative terminal (-).


Check that the terminals and con-
nectors are clean. If they are covered
with sulphate (whitish or greenish
deposit), remove them and clean
them.

Protect your eyes and face be-
fore handling the battery.
All operations on the battery
must be carried out in a well
ventilated area and away from
naked fl ames and sources of
sparks, so as to avoid the risk of
explosion or fi re.
Do not try to charge a frozen
battery; the battery must fi rst
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 qualifi ed workshop
who will check that the inter-
nal 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 with-
out disconnecting the terminals
fi rst.
Wash your hands afterwards.



Reinitialisation after
reconnection

After any reconnection of the battery,
switch on the ignition and wait at least
one minute before starting, to allow
time for the initialisation of the electron-
ic systems.
By referring to the corresponding sec-
tions, you should set or initialise the fol-
lowing systems yourself:


- one-touch electric windows,

- time and date,

- audio and navigation system set-
tings.
Check that no alert message or warn-
ing lamp comes on after switching on
the ignition.
However, if minor problems persist af-
ter carrying out these operations, con-
tact a CITROËN dealer or a qualifi ed
workshop.


Some functions are not available
if the battery is not suffi ciently
charged.









Do not push the vehicle to start
the engine if you have an elec-
tronic or automatic gearbox.
With Stop & Start, the battery
does not have to be disconnect-
ed for charging.

LOAD REDUCTION MODE

System which manages the use of cer-
tain functions according to the level of
charge remaining in the battery.

When the vehicle is being driven, the
load reduction function temporarily de-
activates certain functions, such as the
air conditioning, the heated rear screen...
The deactivated functions are reactivat-
ed automatically as soon as conditions
permit.








ENERGY ECONOMY MODE

System which manages the period of
use of certain functions to conserve a
suffi cient level of charge in the battery.
After the engine has stopped, you can
still use functions such as the audio
equipment, windscreen wipers, dipped
beam headlamps, courtesy lamps, etc.
for a maximum combined period of thirty
minutes.

Switching to economy mode

Once this period has elapsed, a message
appears in the screen indicating that the
vehicle has switched to economy mode
and the active functions are put on standby.
If the telephone is being used at
the same time on the navigation
system, it will be interrupted after
10 minutes.
A fl at battery prevents the en-
gine from starting (refer to the
corresponding paragraph).


Exiting economy mode

These functions are reactivated auto-
matically the next time the vehicle is
driven.



In order to resume the use of these
functions immediately, start the engine
and let it run for a few minutes.
The time available to you will then be
double the period for which the engine
is left running. However, this period will
always be between fi ve and thirty minutes.

This period may be greatly re-
duced if the battery is not fully
charged.
