Stop & Start
Operation
- with a manual gearbox, at speeds below
12 mph (20 km/h) with BlueHDi Diesel
versions, when you put the gear lever into
neutral and release the clutch pedal,
- with an automatic gearbox, vehicle
stationary, when you press the brake pedal
or place 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 automatically: If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It resets
itself to zero every time the ignition
is switched on with the key.
Special cases: STOP mode
unavailable
In this case, the "ECO"
warning
lamp flashes for a few seconds, then
goes off.
This operation is perfectly normal. STOP mode is not invoked when:
- the vehicle is on a steep slope (up or
d ow n),
- the driver's door is open,
- the driver's seat belt is not fastened,
- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine start using
the key,
- the electric parking brake is applied or
being applied,
- the engine is needed to maintain a
comfortable temperature in the passenger
compartment,
- demisting is active,
- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
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.
STOP mode does not affect the functionality of
the vehicle, such as braking, power steering,
for example.Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key.

- with a manual gearbox, when you fully
depress the clutch pedal,
- with an automatic gearbox:
● gear lever in position D or M , when you
release the brake pedal,
● or gear lever in position N and brake
pedal released, when you place the gear
lever in position D or M ,
● or when you engage reverse gear.
Going into engine START
mode
The "ECO" warning lamp goes off
and the engine starts automatically:
Special cases: START invoked
automatically
In this case the "ECO" warning
lamp flashes for few seconds, then
goes off.
This operation is perfectly normal. For safety reasons or to ensure smooth
operation, START mode is invoked
automatically when:
- you open the driver's door,
- you unfasten the driver's seat belt,
- the speed of the vehicle exceeds 15 mph
(25 km/h) with a manual gearbox or 2 mph
(3 km/h) with an an automatic gearbox for
blueH di d iesel versions,
- the electric parking brake is being applied,
- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system. With a manual gearbox in STOP mode,
if a gear is engaged without fully
depressing the clutch pedal, a warning
lamp comes on or an alert message
is displayed asking you to depress the
clutch pedal to restart the engine.

Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.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. 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 (see
the "Identification markings" section).
The tyre pressures must be checked
when the tyres 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.
Driving with under-inflated tyres
increases fuel consumption.
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.
Maintenance
Before doing any work under the
bonnet, deactivate the Stop & Start
system to avoid the risk of injury related
to an automatic change to START
mode.
This system requires the use of a 12 V battery
of specific technology and characteristics
(reference numbers available from a CITROËN
dealer or a qualified workshop).
Fitting a battery not listed by CITROËN would
introduces the risk of faults with the system.
The Stop & Start system makes use of
an advanced technology. All work on
this type of battery must only be carried
out by a CITROËN dealer or a qualified
workshop.

Lighting left on
When a front door is opened with the
ignition off and in manual lighting mode,
an audible signal warns the driver if the
vehicle's lighting is still on.
In this case, switching off the lighting
stops the audible signal.
With the ignition off, if the dipped
headlamps remain on, they will switch
off automatically after thirty minutes to
prevent discharging of the battery.* Depending on the country of sale.

Switching on
F With the ignition off, "flash" the headlamps
using the lighting stalk.
F A further "headlamp flash" switches the
function off.
Switching off
The manual guide-me-home lighting switches
off automatically after a set time.
System which switches on special lamps at the
front, to make the vehicle more visible by day.
They come on automatically and stay on when
the engine is running, if:
-
The function is activated* in the vehicle
parameters menu.
- The lighting control stalk is at position 0
or AUTO .
- The headlamps are off.
You can deactivate the function* via the vehicle
parameters menu. The temporary illumination of the dipped beam
headlamps after the vehicle's ignition has been
switched off makes the driver's exit easier
when the light is poor.

Some functions are not available if the
battery is not sufficiently charged.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area and
away from naked flames and sources
of sparks, so as to avoid the risk of
explosion or 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 CITROËN 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
corrosive acid.
d
o not reverse the polarity and use only
a 12 V charger.
Do not disconnect the terminals while
the engine is running.
Do not charge the batteries without
disconnecting the terminals first.
Wash your hands after wards.
It is advisable to disconnect the battery
if the vehicle is to be left unused for
more than one month.
The batteries contain harmful substances
such as sulphuric acid and lead. They
must be disposed of in accordance
with regulations and must not, in any
circumstances, be discarded with household
waste.
Take used remote control batteries and
vehicle batteries to a special collection point.
d
o not push the vehicle to start the
engine if your vehicle has an automatic
gearbox.
After refitting the battery, the Stop &
Start system will only be active after a

Energy economy mode
System which manages the duration of use of
certain functions to conserve a sufficient level
of charge in the battery.
After the engine has stopped, you can
still use functions such as the audio and
telematics system, windscreen wipers, dipped
beam headlamps, courtesy lamps, etc. for
a maximum combined duration of about
forty minutes.Switching to economy mode
A message then appears in the instrument
panel screen indicating that the vehicle has
switched to economy mode and the active
functions are put on standby.
If a telephone call is being made at this
time, it will be maintained for around
10 minutes with the Bluetooth hands-
free system of your audio system.
