The Stop & Start system puts the engine temporarily into standby - SToP mode - during stops in the traffic (red lights, traffic jams, or other...). The
engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level
when stationary.
Operation
- with a manual gearbox , at speeds below
12 mph (20 km/h), when you put the gear
lever into neutral, and you release the
clutch pedal.
-
w
ith a 5 or 6-speed electronic gearbox ,
when stationary or at speeds below 5 mph
(8 km/h) (depending on version), when you
press the brake pedal or put the gear lever
in position N .
Going into engine STOP
mode
The "ECO" warning lamp comes
on in the instrument panel and the
engine goes into standby:
a
time counter calculates the sum
of the periods in ST
oP m
ode
during a journey. It rests itself
to zero every time the ignition is
switched on with the key.
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
t h e key,
-
t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-
d
emisting is active,
-
s
ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
The "ECO" warning lamp flashes for
a few seconds then goes off.
This operation is perfectly normal.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key. For your comfort, during parking
manoeuvres, ST
oP m
ode is not
available for a few seconds after
coming out of reverse gear.
ST
oP m
ode does not affect the
functionality of the vehicle, such as for
example, braking, power steering...

Going into engine START
mode
The "ECO" warning lamp goes off
and the engine starts:
-
w
ith a manual gearbox , when you
depress the clutch pedal,
-
w
ith a 5-speed or 6-speed electronic
gearbox :
●
g
ear lever in position A or M , when you
release the brake pedal,
●
o
r gear lever in position N and the brake
pedal released, when you move the gear
lever to position A or M ,
●
o
r when you engage reverse gear.
Special cases: START invoked
automatically
For reasons of safety and for your comfort,
START mode is invoked automatically when:
-
y
ou open the driver's door,
-
y
ou unfasten the driver's seat belt,
-
t
he speed of the vehicle exceeds 7 mph
(11 km/h) with the electronic gearbox
system,
-
s
ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed for control of a system.
Deactivation
at any time, press the "ECO OFF" switch to
deactivate the system.
This is confirmed by the switch warning lamp
coming on accompanied by a message in the
screen.
The "ECO" warning lamp flashes for
a few seconds, then goes off.
This operation is perfectly normal.
With a manual gearbox in ST
oP m
ode,
if you engage a gear without fully
depressing the clutch pedal, a message
is displayed asking you to fully depress
the clutch pedal so that the engine can
restart. If the system has been deactivated
in ST
oP m
ode, the engine restarts
immediately.

Checks
12 V battery
The battery does not require any maintenance.
However, check that the terminals are clean
and correctly tightened, particularly in summer
and winter.
The presence of this label, in particular with
the Stop & Start system, indicates the use of
a specific 12
V lead-acid battery with special
technology and specification. The involvement
of a CITROËN dealer or a qualified workshop
is essential when replacing or disconnecting
the battery. When carrying out work on the battery, refer
to the "12 V battery" section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection. Unless other wise indicated, check these components in accordance with the maintenance and warranty guide and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
On a new vehicle, the first operations of
regeneration of the particle emissions
filter may be accompanied by the smell
of "burning", which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
Particle emission filter (Diesel)
accompanied by an audible signal and a
message that there is a risk of blockage of
the particle emissions filter.
Air filter and passenger compartment filter
Refer to the maintenance and
warranty guide for details of the
replacement intervals for these
components.
de
pending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them twice as
often if necessar y .
a c
logged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
Replace the oil filter each time the
engine oil is changed.
Refer to the maintenance and
warranty guide for details of the
replacement interval for this
component.

carried out in a well ventilated area
away from naked flames and sources
of sparks, so as to avoid the risk of
explosion and fire.
Do not try to charge a frozen battery;
the battery must first be thawed out to
avoid the risk of explosion. If the battery
has been frozen, before charging have
it checked by a CITR
oËn
dealer or a
qualified workshop who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
