a secret code. When the ignition is switched 
on, this code must be recognised in order for 
starting to be possible.
This electronic engine immobiliser locks the 
engine management system a few minutes 
after the ignition is switched off and prevents 
starting of the engine by anyone who does not 
have the key.
In the event of a malfunction, you are informed 
by a message in the instrument panel screen.

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.

If your vehicle is fitted with the system, a time 
counter calculates the sum of the periods in 
STOP mode during a journey. It resets itself to 
zero every time the ignition is switched on with 
the START/STOP button. Never refuel with the engine in STOP 
mode; you must switch off the ignition 
with the START/STOP button. For your comfort, during parking 
manoeuvres, STOP mode is not 
available for a few seconds after 
coming out of reverse gear.
The Stop & Start system does not affect 
the functionality of the vehicle, such as 
for example, braking, power steering...
Special cases: STOP mode not 
available
STOP mode is not invoked when:
-
 t he driver's door is open,
-
 
t
 he driver's seat belt is not fastened,
-
 
t
 he vehicle has not exceeded 6 mph 
(10
  km/h) since the last engine start using 
the START/STOP button,
-
 
t
 he electric parking brake is applied or 
being applied,
-
 
t
 he engine is needed to maintain a 
comfortable temperature in the passenger 
compartment,
-
 
d

-
 
s
 ome special conditions (battery charge, 
engine temperature, braking assistance, 
exterior temperature, etc.) where the 
engine is needed for control of a system.
In this case, this indicator lamp flashes 
for a few seconds then goes off.
This operation is perfectly normal.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.

Operating fault
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 selector 
lever at 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.
In the event of a fault with the system, 
this indicator lamp flashes for a few 
moments then comes on continuously, 
accompanied by a message.
Opening the bonnet
Before doing anything under the 
bonnet, deactivate the Stop & Start 
system to avoid the risk of injury related 
to an automatic change to START 
mode.
Driving on flooded roads
Before driving through a flooded road, 
it is strongly recommended that you 
deactivate the Stop & Start system.
For more information on Driving 
advice
, particularly on flooded roads, 
refer to the corresponding section. The Stop & Start system requires a 
battery of advanced technology and 
special characteristics.
All work on this type of battery must 
only be done by a CITROËN dealer or a 
qualified workshop.
For more information on the 12 V 
battery
, refer to the corresponding

Cruise control - "CRUISE"
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control system cannot, in any circumstances, replace the need to observe speed limits, nor can it replace the need for vigilance on the part of the driver.
You are advised to keep your feet near the pedals at all times.
S
witching on  the cruise control requires a 
minimum vehicle speed of 25 mph (40 km/h).
As well as engagement of:
-
 
f
ourth gear or higher on a manual gearbox,
-
 
s
econd gear or higher in manual mode on 
an automatic gearbox,
-
 
position 
D on an automatic gearbox.
The system remains active after changing gear 
on vehicles with a manual gearbox and Stop & 
Start.
The cruise control is paused  by pressing 
button 4 or the brake pedal or on triggering of 
the ESC system for safety reasons.
It is possible to exceed the programmed speed 
temporarily by pressing the accelerator pedal.
To return to the programmed speed, simply 
release the accelerator pedal until the 
programmed cruise speed is reached again. 1.

The dynamic cruise control is switched on 
manually: it requires that the speed of the 
vehicle be between 25 and 90 mph (40 and 
150
  km/h), as well as the engagement of:
-
 
f
 ourth gear or higher with a manual 
gearbox,
-
 
s
 econd gear or higher with an automatic 
gearbox in manual mode,
-
  position  D with an automatic gearbox.
The system remains active after changing gear 
on vehicles with a manual gearbox and Stop & 
Start.
General points
The dynamic cruise control can be paused  
manually or automatically:
-
 
b
 y pressing button 4 ,
-
 
b
 y pressing the brake pedal,
-
 
i
 n the event of operation of the ESC, for 
safety reasons,
-
 
i
 n the event of operation of the electric 
parking brake control lever,
-
 
w
 hen an inter-vehicle time threshold is 
reached (calculated according to the 
relative speeds of your vehicle and the 
vehicle in front and the inter-vehicle time 
setting chosen),
-
 
w
 hen the distance between your vehicle 
and the one in front becomes too small,
-
 
w
 hen the speed of the vehicle in front is 
too
 
low,
-
 
w
 hen the speed of your vehicle becomes 
too low.
The dynamic cruise control cannot in any 
circumstances replace the observation 
of speed limits, nor the need for vigilance 
on the part of the driver.
It is recommended that you always keep 
your feet close to the pedals. If the speed setting selected is above 
90 mph (150 km/h), the system switches 
to standard cruise control operation, 
with no adjustment of the inter-vehicle 
safe distance (a message appears in 
the instrument panel). The inter-vehicle time setting is kept in 
memory on switching off the ignition.
The dynamic cruise control operates by 
day and at night, in fog or in moderate 
rainfall.
The system does not act on the braking 
system, but works only with engine braking.
The regulation range is limited: there will 
no longer be any adjustment of speed if the 
difference between the programmed speed 
setting and the speed of the vehicle in front 
becomes too high (18 mph (30 km/h)).
If the difference between the 
programmed speed setting and the 
speed of the vehicle in front is too 
great, the speed cannot be adjusted: 
the cruise control is automatically 
deactivated.
