Stop & Start
This system puts the engine tempo-
rarily into standby during stops in the
traffi c (red lights, traffi c jams, etc...).
The engine restarts automatically as
soon as you want to move off.
Stop & Start reduces fuel consumption,
exhaust emissions and noise when
stationary.

unwittingly cross a lane marking.
Parking sensors

the vehicle.
Tyre under-infl ation detection
This system checks the pressure
of the tyres automatically while

headlamps
This system automatically provides
you with extra visibility on bends.
This lighting is linked with the cor-

PARKING SPACE SENSOR
System which measures the park-
ing space available between two
vehicles or obstacles. It measures
the size of the space and gives you
information on:
- the possibility of fi tting into a free space, depending on the dimen-
sions of your vehicle and the
distances necessary for your
manoeuvring,
- the level of diffi culty of the ma- noeuvre to be performed.
The system does not measure spac-
es which are clearly much smaller or
larger than the size of the vehicle. Displays on the instrument
panel
The parking space sensor function
warning lamp can have three differ-
ent states:
-
off: the function is not selected,
- on fi xed: the function is selected
but the conditions for measuring

the measurement is terminated,
- fl ashing: measurement is in
progress or the message is be-
ing displayed. You can select the "parking space
sensor" function by pressing button

need for vigilance and responsibility
on the part of the driver.
VISUAL AND AUDIBLE FRONT AND/OR REAR PARKING SENSORS
System consisting of proximity sen-
sors, installed in the front and/or rear
bumper.
It detects any obstacle (person, vehi-
cle, tree, barrier...) located in front of
or behind the vehicle, however, it will
not be able to detect obstacles locat-
ed immediately below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it.
The parking sensors are switched on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h)
in forward gear.
This is accompanied by an audible
signal and/or displaying of the vehi-
cle on the multifunction screen.
The proximity information is indicat-
ed by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction display, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the ve-
hicle and the obstacle is less than
approximately thirty centimetres, the
audible signal becomes continuous
and/or the "Danger" symbol appears,
depending on the multifunction screen
version.
The parking sensors are switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward gear,
- when the vehicle has been station- ary for more than three seconds in
forward gear. Deactivation

 Press button A , the warning lamp
comes on, the system is fully de-
activated.
The system will be deactivated au-
tomatically when a trailer is being
towed or when a bicycle carrier is
fi tted (vehicle fi tted with a towbar
or bicycle carrier recommended by
CITROËN).
