Stop & Start
The Stop & Start system puts the engine
temporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams, etc.).
The engine restarts automatically – START
mode – as soon as you wish to move off.
Restart is instantaneous, quick and silent.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions and offers the comfort of complete
silence when stationary.
Going into engine STOP
mode
With the vehicle stationary, put the gear lever
into neutral, then release the clutch pedal.This indicator lamp comes on in the
instrument panel and the engine
goes into standby.
Automatic stopping of the engine is only
possible after the vehicle has exceeded
a
speed of about 6 mph (10 km/h), to avoid
repeated stopping of the engine when
driving slowly. Never leave your vehicle before turning off
the ignition with the key.
Never refuel with the engine in STOP
mode; you must switch off the ignition
using the key.
Special cases: STOP mode
not available
STOP mode is not triggered when:
-
t he system is initialising,
-

t
he driver's door is open,
-

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

t
he air conditioning is on,
-

t
he rear screen demisting is on,
-

t
he windscreen wipers are on fast wipe,
-

r
everse gear is engaged for a parking
manoeuvre,
-
s

ome special conditions (battery charge,
engine temperature, particle filter
regeneration, braking assistance, exterior
temperature, etc.) where the engine is
needed to assure control of a
system.-

d
uring intensive use of Stop & Start, it
may be deactivated to conser ve starting
ability; go to a CITROËN dealer to have the
function reactivated.
This indicator lamp in the instrument
panel flashes for a few seconds,
then goes off.

Going into engine START
mode
With the vehicle in gear, automatic engine
restarting is only allowed by fully depressing
the clutch pedal.
This indicator lamp goes off and the
engine restarts.
If the driver takes no action on the vehicle for
3
minutes after an automatic restart in START
mode, the system stops the engine definitively.
The engine can then only be restarted using
t h e key.

Special cases: START mode
activated automatically
The START mode may be triggered
automatically in the following circumstances:
-
t
he vehicle is free-wheeling on a gradient,
-

t
he windscreen wipers are on fast wipe,
-

t
he air conditioning is on,
-

t
he engine has been stopped for around
3
minutes with Stop & Start,
-
s

ome special conditions (battery charge,
engine temperature, braking assistance, air
conditioning setting, etc.) where the engine
is needed to control a
system or the vehicle.
In this case, a message appears
in the instrument panel screen,
accompanied by this indicator lamp,
which flashes for a
few seconds,
then goes off.
This operation is perfectly normal. While in STOP mode with a
manual
gearbox, if a gear is engaged without fully
depressing the clutch pedal, restarting
may not take place.
An indicator lamp and/or message is
displayed in the instrument panel asking
you to fully depress the clutch pedal to
allow restarting.
With the engine stopped in STOP
mode, if the driver unfastens their
seat belt and opens a
front door, the
engine can only be restarted using
the ignition key. There is an audible
signal, accompanied by flashing of
this indicator lamp, and the display
of a
message.
Deactivation
If the system has been deactivated
in STOP mode, the engine restarts
immediately.
It is necessary to deactivate the
Stop & Start system if you want to
allow continuous operation of the air
conditioning.
The button indicator lamp remains on.

Reactivation
Malfunction
F Press this button again.
The system is active again; this is confirmed
by the button indicator lamp going out and the
display of a message.
In the event of a
fault with the system,
the Stop & Start system is deactivated
and this warning lamp comes on,
accompanied by a
message in the
instrument panel screen.
Maintenance
Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from an
automatic change to START mode.
The Stop & Start system makes use of
an advanced technology. All work on
this type of battery must be carried out
only by a
CITROËN dealer or a qualified
workshop.
Have it checked by a CITROËN dealer or by
a qualified workshop.
In the event of a
malfunction in STOP mode, it is
possible to restart the engine by depressing the clutch
pedal fully or by putting the gear lever into neutral.
This system requires a specific battery
w ith a special specification and technology
(reference numbers available from a
CITROËN
dealer or a
qualified workshop).
Fitting a
battery not approved by CITROËN
introduces the risk of malfunction of the
system.
For more information on the Battery , refer to
the corresponding section.
Hill start assist
System which keeps your vehicle stationary
for a short time (approximately 2 seconds)
when starting on a
gradient, the time it takes
to move your foot from the brake pedal to the
accelerator pedal.
This system (also called HHC – Hill Holder
Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
-

t
he vehicle must be stationary, engine
running, foot on the brake,
-

t
he gradient of the road must be steeper
than 5%,
-

u
phill, the gearbox must be in neutral or in
a


gear other than reverse,
-
do

wnhill, reverse gear must be engaged.
The hill start assist system is a
driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.

Filter, air
At the start of winter, have your battery checked
by a CITROËN dealer or a qualified workshop.
For best quality cleaning and to prevent
freezing, this fluid must not be topped up or
replaced with plain water.
In wintry conditions, the use of an alcohol or
methanol based fluid is recommended.
Refer to the manufacturer's
ser vice schedule for details of
the replacement inter val for this
component.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace it twice as often if
necessary .
Filter, passenger
compartment
Refer to the manufacturer's
ser vice schedule for details of
the replacement inter val for this
component. Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace it twice as often if

Particle filter (Diesel)
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
As an addition to the catalytic converter,
this filter makes an active contribution to the
preser vation of air quality by retaining unburnt
pollutant particles. Black exhaust fumes are
also eliminated.
