Starting the vehicle
)Insert the key in the ignition switch.
The system recognises the star ting code. )Turn the key fully towards the dashboard toposition 3 (Starting).)When the engine star ts, release the key.
) Immobilise the vehicle.)
Turn the key fully towards you to
position 1 (Stop).)
Remove the key from the ignition switch.
Switching the vehicle off
Do not attach any heavy objects tothe key as this could weigh down on itwhen in the ignition switch and cause a fault.


Key reminder

If the key is left in the ignition switch, anaudible signal sounds when the driver's door is opened.

149Safety
Emergency braking assistance
System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.

Activation

It is triggered by the speed at which the brake pedal is pressed.
The effect of this is a reduction in theresistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press firmly without releasing the pressure.














Trajectory control systems
Anti-slip regulation (ASR)
and electronic stability
pro
gramme (ESP)
The anti-slip regulation (also known as TractionControl) optimises traction to prevent skiddingof the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability programme acts on the
brake of one or more wheels and on the engine
to keep the vehicle on the trajectory required
by the driver, within the limits of the laws of physics.

Activation

These systems are activated automaticallyeach time the vehicle is started.
They come into operation in the event of a gripor trajectory problem.
This is indicated b
y flashing of this
warning lamp in the instrument panel.

Driving
This section describes the use of the parking brake, the manual,electronic or automatic gearbox, the gear efficiency indicator and Stop & Start to help reduce fuel consumption, hill start assist, the speed limiter to avoid exceeding a programmed speed, cruise control
to maintain a programmed speed, the rear parking sensors to detectobstacles.

Stop & Start 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 restar ts automatically - START mode - as soon as you want to move off. The restar t 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
Going into engine STOP mode
For your comfor t, during parkingmanoeuvres, STOP mode is not available for a few seconds after coming out of reverse gear.STOP mode does not affect the functionality of the vehicle, such as for example, braking, power steering...
Never refuel with the engine in STOPmode; you must switch off the ignition with the key. Th
e "ECO"warning lamp comes
on in the instrument panel and the engine goes into standby:
- with a manual gearbox
, at speeds below
12 mph (20 km/h), when you put the gear lever into neutral, and you release theclutch pedal. -with a 5 or 6-speed electronic gearbox ,
at speeds below 5 mph (8 km/h), when you press the brake pedal or put the gear lever in position N.
A time counter calculates the sum
of the periods in STOP mode
during a journey. It rests itself
to zero every time the ignition is switched on with the key.
STOP mode is not invoked when:


- 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 star t using
the key,

- the engine is needed to maintain acomfortable temperature in the passenger compartment,

- demisting is active,

- some special conditions (battery charge, engine temperature, braking assistance,ambient temperature...) where the engine isneeded to assure control of a system.


Special cases: STOP mode not available

The "ECO"warning lamp flashes for
a few seconds then goes off.
This operation is per fectly normal.

175
Driving

Going into engine START mode
The "ECO"warning lamp goes off and the engine star ts:


-
with a manual gearbox
, when you
depress the clutch pedal,

- with a 5-s
peed or 6-speed electronic gearbox:
●
gear lever in position Aor M
, when yourelease the brake pedal,
●
or gear lever in position Nand the brake pedal released, when you move the gear lever to position A
or M,
●
or when you engage reverse gear.


Special cases: START invoked automatically


If the system has been deactivatedin STOP mode, the engine restar ts immediately.

At any time, press the "ECO OFF"
switchto deactivate the system.
This is confirmed by the switch warning lamp coming on accompanied by a message in
the screen.

Deactivation
For reasons of safety and for your comfort,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 7 mph
(11 k m/h) with the electronic gearbox system,
- some special conditions (battery charge,engine temperature, braking assistance,
ambient temperature...) where the engine
is needed for control of a system.
Th
e "ECO"
warning lamp flashes for
a few seconds, then goes off.
This operation is per fectly normal.
With a manual gearbox in STOP mode,if you engage a gear without fully depressing the clutch pedal, a message is displayed asking you to fully depressthe clutch pedal so that the engine can restart.

The system is reactivated automaticallyat every new star t using the key.
Reactivation
This system requires a battery with a specialspecification and technology (reference numbers available from a CITROËN dealer
or a qualified workshop).
Fitting a battery not listed by CITROËN introduces the risk of malfunction of
the system. In the event of a fault with the system, the
"ECO OFF"
switch warning lamp flashes thencomes on continuously.
Have it checked by a CITROËN dealer or aqualified workshop.
In the event of a fault in STOP mode, the
vehicle may stall. All of the instrument panel
warning lamps come on. It is then necessaryto switch off the ignition and star t the engine
again using the key.


Operating fault
Maintenance


Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of STA R T mode.


The Stop & Start system makes use of advanced technology. All work
on this type of battery must be doneby a CITROËN dealer or a qualifiedworkshop. Pr
ess the "ECO OFF"switch again.
The system is active again; this is confirmed
by the switch warning lamp going off,accompanied by a message in the screen.

Checks
Battery

Air filter and passenger compartment filter


Oil filter
Par ticle emission filter (Diesel)
Unless other wise indicated, check these components in accordance with the ser vicing booklet and according to your engine.
Other wise, have them checked b
y a CITROËN dealer or a qualified workshop.
The batter
y does not require any
maintenance.

However, check that the terminals
are clean and correctly tightened,
particularly in summer and winter.
When carrying out work on the battery, refer to
the "Practical information" section for details of
the precautions to be taken before disconnecting
the battery and following its reconnection. Re
fer to the ser vicing booklet for
details of the replacement inter vals
for these components.
Dependin
g on the environment (e.g.
dusty atmosphere) and the use of the vehicle(e.g. city driving), replace them twice as often
if necessary(refer to the "Engines" section).
A clogged passenger compar tment filter may
have an adverse effect on the performance
of the air conditioning system and generateundesirable odours.
Re
place the oil filter each time
the engine oil is changed.
Re
fer to the ser vicing booklet for
details of the replacement inter val
for this component. The
presence of this label, in par ticular with
the Stop & Star t system, indicates the use of a specific 12 V lead-acid battery with special
technology and specification, for which the
involvement of a CITROËN dealer or a qualified
wor
kshop is required when replacing or disconnecting the battery. Failure to observe this recommendation mayshor ten the life of the battery. Th
e start of saturation of theparticle filter is indicated by the
temporary illumination of this warning lamp
accompanied by a message in the multi-
function screen.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 40 mph (60 km/h) until the warning lampgoes off.
If the warning lamp stays on, this indicates a low additive level.

On a new vehicle, the first par ticlefilter regeneration operations may be accompanied by a "burning" smell, which is perfectly normal.
Following prolonged operation of thevehicle 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.
