Service Temporarily on,
accompanied by the
display of a
message. One or more minor anomalies,
for which there is/are no specific
warning lamp, have been detected. Identify the cause of the anomaly using the message
displayed in the instrument panel.
You can deal with certain anomalies yourself, for
example an open door or the start of saturation of the
particle filter.
For other anomalies, such as a
fault with the tyre
under-inflation detection system, carry out (3).

Diesel engine
pre-heating Fixed.
The period of
illumination depends
on the climatic
conditions. The ignition is on.
Wait until the warning lamp goes off before starting.
If the engine does not start, switch the ignition off and
then on, wait until the lamp goes off again, then start
the engine.
Front passenger
airbag (ON) Fixed.
The front passenger airbag is
activated.
The control is in the "ON" position. In this case, do NOT install a "
rearward facing"
child seat on the front passenger seat – risk of
serious injury!
Front passenger
airbag (OFF) Fixed.
The front passenger airbag is
deactivated.
The control is in the "OFF" position. You can install a "rear ward facing" child seat, unless
there is a
fault with the airbags (Airbags warning lamp

dealer or a
qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if this fault occurs.The Stop & Start system requires a
12 V
battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
After the engine has restarted, STOP
mode is not available until the vehicle has
reached a speed of 5 mph (8 km/h).
During parking manoeuvres, STOP mode
is not available for a few seconds after
coming out of reverse gear or turning the
steering wheel.
The engine automatically restarts as soon as
the driver indicates the intention of moving off
again.
Tyre under-inflation
detection
This system automatically checks the
pressures of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
Driving

133
must be reinitialised ever y time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a
drop in the inflation pressure of one
or more tyres.
Under-inflation detection does not replace
the need for vigilance on the part of the
driver.
This system does not avoid the need
to regularly check the tyre pressures
(including the spare wheel) as well as
before a


long journey.
Driving with under-inflated tyres,
particularly in adverse conditions (heavy
load, high speed, long journey):
-
w

orsens road-holding,
-
l

engthens braking distances,
-

c
auses premature wear of the tyres,
-

i
ncreases 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. 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 to the pressures
shown on the label.
Under-inflation alert
This is signalled by continuous
illumination of this warning lamp,
an audible signal and the display of
a


message.

R

educe speed immediately, avoid excessive
steering movements and avoid sudden
braking.
F

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 rely on just a
visual check. F

I
f it is not possible to make this check
immediately, drive carefully at reduced
speed.
F
I
n the event 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 pressure of one or more
tyres, and after changing one or more wheels.
F

U

sing a

compressor, such as the one in the
temporary puncture repair kit, check the
pressures of the four tyres when cold. Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written
on the tyre pressure label.
Check the pressures of the four tyres
before performing the reinitialisation.
The system does not advise if a
pressure
is incorrect at the time of reinitialisation.

With the vehicle stationary, the
system is reinitialised via the
Driving/Vehicle menu of the touch
screen.

n this menu, select the " Driving functions"
tab.

ect " Ye s" to confirm.
The reinitialisation is confirmed by the display
of a

message and an audible signal.
Malfunction
In this case, under-inflation monitoring of the
tyres is no longer assured.
Have the system checked by a CITROËN
dealer or a
qualified workshop.
