The gearbox then operates in auto-adaptive
mode, without any action on the par t of the
driver. It continuously selects the most suitable
gear in relation to the following parameters:


- driving style,

- road conditions,

- vehicle load.

Stop & Start
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, etc...). The engine
restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as offering the comfort of silence when
stationary.

Operation


Going into engine STOP mode

For your comfort when parking, 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.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key. The "ECO"
warning lamp comes
on in the instrument panel and the
engine goes into standby:


- with a manual gearbox
, at speeds below
12 mph (20 km/h), when you put the gear
lever into neutral, and you release the
clutch pedal,
A time counter calculates the sum
of the periods in STOP mode
during a journey. It rests itself
to zero every time the ignition is
switched on with the key. 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 star t using
the key,

- the engine is needed to maintain a
comfor table temperature in the passenger
compartment,

- demisting is active,

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


Special cases: STOP mode
unavailable
The "ECO"
warning lamp flashes for
a few seconds, then goes off.

This operation is per fectly normal.

167Driving

Going into engine START mode

The "ECO"
warning lamp goes off
and the engine star ts:


- with a manual gearbox
, when you fully

depress the clutch pedal.


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

For your safety and comfort, START mode is
invoked automatically 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,

- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
The "ECO"
warning lamp flashes, then
goes off.

This operation is per fectly normal.


With a manual gearbox in STOP mode,
if a gear is engaged without fully
depressing the clutch pedal, a message
is displayed asking you to depress the
clutch pedal to restar t the engine.

The system is reactivated automatically
at every new star t using the key.


Reactivation

This system requires a 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. In the event of a malfunction 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. It is then necessary to switch
off the ignition and star t the engine again using
the key.


Operating fault
Maintenance

Before working under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from
automatic operation of START mode.
The Stop & Star t system makes use of
advanced technology. All work on this
battery must be done by a CITROËN
dealer or a qualified workshop. Press the "ECO OFF"
switch again.
The system is active again; this is confirmed
by the switch warning lamp going off,
accompanied by a message in the screen.

217Practical information











Battery
Procedure for charging your battery when it is flat or for starting the engine using another 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,

)
secure the bonnet stay,

)
lift the plastic cover on the (+) terminal.



Access to the battery



)
Connect the red cable to the positive
terminal (+) of the flat battery A
, then to the
positive terminal (+) of the slave battery B
.


Starting using another
battery

After refitting the battery by a
CITROËN dealer or a qualified
workshop, the Stop & Star t 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).





The presence of this label, in particular
with the Stop & Star t 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.
Failure to obser ve this recommendation
may cause premature wear of
the battery.

)
Connect one end of the green or black
cable to the negative terminal (-) of the
slave battery B
.

)
Connect the other end of the green or black
cable to the remote negative terminal (-) of
your vehicle.

219Practical information








Energy economy mode
System which manages the period of use of cer tain functions to conser ve a sufficient 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, cour tesy
lamps, etc. for a maximum combined period of thirty minutes.
This period may be greatly reduced if
the battery is not fully charged.
A flat battery prevents the engine from
starting (refer to the corresponding
paragraph). If the telephone is being used at
the same time on the MyWay audio
navigation system, it will be interrupted
after 10 minutes.


Switching to economy mode

Once this period has elapsed, a message
appears on the multifunction screen indicating
that the vehicle has switched to economy mode
and the active functions are put on standby.

Exiting economy mode

These functions are reactivated automatically
the next time the vehicle is driven.


)
In order to resume the use of these
functions immediately, star t 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
five and thir ty minutes.
