Have it checked by a CITROËN dealer or
a qualified workshop.
If a
fault occurs in STOP mode, the engine 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 lever in
position N and press the brake pedal.
It is then necessary to switch off the ignition and
start the engine again using the "START/STOP"
button.
The Stop & Start requires the use of
a 12 V battery of special specification and
technology.
All work on this type of battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
For more information on the 12
V batter y,
refer to the corresponding section.
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 in a
flooded area, 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.
Tyre under-inflation
detection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure of the four
tyres when the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change .
The system triggers an alert as soon as it
detects a
drop in the pressure of one or more
tyres. The under-inflation detection system does
not replace the need for vigilance on the
part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a


long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section.
Driving

143
Checking tyre pressures
This check should be done when the tyres
are "cold" (vehicle stopped for 1 hour or
after a
journey of less than 6 miles (10 km)
at moderate speeds).
Other wise, add 0.3
bar (30 kPa) to the
values indicated on the label.
Under-inflation alert
This is indicated by continuous
illumination of this warning lamp,
an audible signal and, depending
on equipment, the display of
a


message.

S

top the vehicle as soon as it is safe to do
so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a
visual
check. F

I
f it is not possible to make this check
immediately, drive carefully at reduced
speed.
or
F
I
n case of a puncture, use the temporary
puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is
reinitialised.Reinitialisation
The system must be reinitialised after any
adjustment to the pressures of one or more
tyres, and after changing one or more wheels.
Before reinitialising the system, ensure
that the pressures of the four tyres
are correct for the conditions of use
of the vehicle and conform to the
recommendations on the tyre pressure
label.
The under-inflation alert can only be relied
on if the reinitialisation of the system has
been done with the pressures in the four
tyres correctly adjusted.
The under-inflation detection system
does not give a
warning if a pressure is
incorrect at the time of reinitialisation. Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Reinitialisation of the system is done on the
touch screen, with the ignition on and the
vehicle stationary.
F
I
n the Driving
menu, select the " Driving
functions " tab, then " Under-inflation
initialisation ".
F
C
onfirm the instruction by pressing "
Ye s",
an audible signal and a message confirm
the reinitialisation.
The new pressure parameters saved are
treated as reference values by the system.
Malfunction
F If you have a compressor, such as the one
in the temporary puncture repair kit, check
the pressures of the four tyres when cold. In this case, under-inflation monitoring of the
tyres is no longer provided.
Have the system checked by a
CITROËN
dealer or a
qualified workshop.
The flashing and then fixed illumination of the
under-inflation warning lamp accompanied
by illumination of the Ser vice warning lamp
indicates a
fault with the system.
A message appears, accompanied by an
audible signal.

Speed limiter "LIMIT"
System which prevents the
vehicle from exceeding the speed
programmed by the driver.
Once the programmed speed limit is reached,
additional pressure on the accelerator pedal
has no effect.
Operation of the speed limiter requires
a

programmed speed of at least 19 mph
(30


km/h).
The speed limiter is paused using the control.
The programmed speed can be exceeded
temporarily by pressing the accelerator firmly
beyond the point of resistance.
To return to the programmed speed, simply
release the accelerator pedal until the set
speed limit has been reached again.
The programmed speed remains in the system
memory when the ignition is switched off.
The speed limiter cannot, in any circumstances,
replace the need to obser ve speed limits, nor can it
replace the need for vigilance on the part of the driver.

The adaptive cruise control uses only
engine braking to slow the vehicle.
Consequently the vehicle loses speed
slowly, as when releasing the accelerator
pedal.
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 (19 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.
General information
The adaptive cruise control is switched on
manually, it requires the speed of the vehicle
to be between 25
mph (40 km/h) and 93 mph
(150


km/h) and the engagement of:
-

t
hird gear or higher with a manual gearbox,
-

s
econd gear in manual mode with an
automatic gearbox,
-
position D with an automatic gearbox. If the cruise speed setting is above
93
mph (150 km/h), the adaptive cruise
control switches to standard cruise control
mode, without automatic regulation of the
inter-vehicle safety distance (a message
appears in the instrument panel).
The adaptive cruise control cannot in any
circumstances replace the obser vation of
speed limits, nor the need for the vigilance
on the part of the driver.
It is recommended that you always keep
your feet close to the pedals.
The adaptive cruise control can be paused
manually or automatically:
