STOP & START
The Stop & Start system puts the en-
gine temporarily on 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
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
release the clutch pedal, If your vehicle is fi tted with
the system, a time counter
calculates the sum of the pe-
riods in STOP mode during a
journey. It resets itself to zero every time
the ignition is switched on with the key.
- with the 6-speed electronic gear-
box system
, at a speed below
5 mph (8 km/h), when you press the
brake pedal or put the gear lever
into position N
. With the automatic gearbox
system, for your comfort dur-
ing parking maoeuvres, STOP
mode is not available for a few
seconds after coming out of re-
verse 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"
warning
lamp fl ashes for a few seconds,
then goes off. Never refuel with the engine in
STOP mode; you must switch off
the ignition with the key.

or a qualifi ed workshop.
In the event of a fault in STOP mode,
the vehicle may stall. It is then neces-
sary to switch off the ignition and start
the engine again using the key.
Operating fault
Before working under the bon-
net, 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.

while the engine is running.
Do not charge the batteries without
disconnecting the terminals fi rst.
Do not push the vehicle to start the
engine if it is fi tted with the 6-speed
electronic gearbox system.
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 start-
ing to permit initialisation of the
electronic systems. However, if
problems are encountered fol-
lowing this operation, contact a
CITROËN dealer or a qualifi ed
workshop.
Referring to the corresponding
section, you must yourself reini-
tialise:
- the remote control key,
- the panoramic sunroof blind,
- the GPS satellite navigation
system.
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 deac-
tivates 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 ve-
hicle 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 af-
ter 10 minutes.
A fl at battery prevents the engine
from starting (refer to the corre-
sponding 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.
