Stop & Start (Auto Stop & Go) system
Operation
Going into engine STOP mode
The "AS &G" warning lamp comes on in
the instrument panel or the instrument
panel screen and the engine goes into
standby after a few seconds:
- with a manual gearbox , with the vehicle
stationary and your foot on the brake, when
you put the gear lever into neutral and
release the clutch pedal.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key or the START/STOP
button. When the engine is stopped
automatically, the operation of certain
vehicle systems, such as braking
and power steering for example, are
modified. Ta k e c a r e .
Special cases: STOP mode not

-
t he driver's seat belt is not fastened,
-

t
he driver's door is open,
-

t
he bonnet is open,
-

t
he minimum time period of 30 seconds
since starting the engine has not elapsed,
-

t
he vehicle speed has not exceeded 3 mph
(5 km/h) since the last engine start,
-

t
he vehicle has restarted less than
10
seconds ago,
-

t
he engine is needed to maintain a
comfortable temperature in the passenger

engine temperature, braking assistance,
exterior temperature, etc.) where the
engine is needed to assure control of a
system,
-
the "AS &G" warning lamp is
flashing in the instrument panel.
This operation is perfectly normal.
The Stop & Start (Auto Stop & Go) system puts the engine temporarily into standby during stops in the traffic (red lights, traffic jams, etc.). The engine
restarts automatically as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start (Auto Stop & Go) system reduces fuel consumption and exhaust emissions as well as the noise level when
stationary.
If you move the gear lever, the "AS &G"
warning lamp flashes, accompanied by
an audible signal.
The alert stops as soon as the gear
lever is returned to the neutral position.
When driving, prolonged pressing of the

The tyre under-inflation detection
system is an aid to driving which does
not replace the need for vigilance on
the part of the driver.
Under-inflation detection
System which continuously and automatically checks the pressures of the four tyres after switching on the ignition.
A pressure sensor is located in the valve of each tyre (except the spare wheel).
The system triggers an alert if a drop in pressure is detected in one or more tyres, compared to the reference pressure registered in the system. This
reference pressure must be reinitialised every time the tyre pressures are adjusted or a wheel changed.
The system operates on condition that the sensor identifiers have first been memorised in the system by a CITROËN dealer or a qualified workshop.
You can memorise two sets of tyres (e.g. wheels with "standard" tyres and wheels with "winter" tyres).Driving with under-inflated tyres
increases fuel consumption.This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre pressures for your vehicle can
be found on the tyre pressure label.
For more information on Identification
markings
, refer to the corresponding
section.
The tyre pressures must be checked
when the tyres are cold (vehicle
stopped for 1 hour or after driving for
less then 6 miles (10 km) at moderate
speed). Other wise, add 0.3 bar to the
values indicated on the label.

top as soon as it is safe to do so. The loss of pressure detected does not
always lead to visible deformation of the
tyre. Do not rely on just a visual check. The alert is maintained until the
reference pressure is reinitialised after
the inflation, repair or replacement of
the tyres concerned. In the event of
the repair or replacement of tyres, the
sensor identifiers must be registered in
the system by a CITROËN dealer or a
qualified workshop.
The spare wheel does not have
a sensor, so there is no need to
reinitialise the system for driving with
the spare wheel fitted.
F
I f you have a compressor (the one in the
temporary puncture repair kit, for example),

I

f it is not possible to check the tyre
pressures 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).
Reinitialising the reference
pressure
Before reinitialising the system, ensure
that the pressures in the four tyres are
suitable for the conditions of use of the
vehicle and are as specified on the tyre
pressure label.
The under-inflation detection system
cannot warn of an incorrect pressure at
the time of reinitialisation.
The system must be reinitialised after any
adjustment of tyre pressures and after
changing one or more wheels.
