Starting the vehicle
)Inser t 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

A heavy object (key fob...), attached to the key and weighing down on its shaft in the ignition switch, could cause amalfunction.
Key left in the "Ignition on"position
On opening the driver's door, an aler t message is displayed, accompaniedby an audible signal, to remind you that the key is still in the ignition switch atposition 1 (Stop).
If the key has been left in the ignitionswitch at position 2 (Ignition on),the ignition will be switched off automatically after one hour. To switch the ignition back on, turn the key to position 1 (Stop)
, then back toposition 2 (Ignition on).

177Safety
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 (ESP)
Anti-slip regulation (ASR)
and electronic stability
control (ESC)
The anti-slip regulation (also known as traction control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.The electronic stability control 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.

Intelligent traction control
s
ystem ("Snow motion")
Your vehicle has a system to help driving on snow: intelligent traction control.
This system detects situations of difficult surface adhesion that could make it difficult to
move off or make progress on deep fresh snowor compacted snow.
In these situations, the intelligent tractioncontrol limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly recommended on surfaces offering low levels of adhesion.

Driving
)Pierce the protective cover Don the tube Ewith the release device. )Place the release device in the tube.)Turn the release device clockwise . For
safety reasons, it is essentialto continue
turning the device until it reaches its stop.
The parking brake is released. )Remove the release device and store it
with the blocks in the toolbox under theboot carpet.


For safety reasons, after this operationit is essential to contact a CITROËN dealer or a qualified workshop without delay to replace the protective cover.
Following an emergency unlocking,immobilisation of the vehicle is nolonger assured once the manual emergency release has been deployed
and the manual control does not allowthe re-application of your parkingbrake.
Take no action, either on the control lever A, or stopping starting the engine while the release device is engaged.
Take care not to allow moisture or dust in the proximity of the protective cover. - The operation o
f the parking brake reinitialises when the ignition is switched
off then on again. If the reinitialisation
of the parking brake proves impossible, contact a CITROËN dealer or a qualified
workshop.
- The subsequent time required for
app
lication may be longer than during
normal operation.

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 & Star t system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
With the electronic gearbox system, for your comfor t during parking maoeuvres, 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 asbraking, power steering, for example.
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 automatically:
-with a manual gearbox , at speeds below
12 mph (20 km/h), when you put the gear lever into neutral and release the clutchpedal,
- with the 6-speed electronic gearbox
system, at a speed below 5 mph (8 km/h),
when you press the brake pedal or put thegear lever into position N.
If your vehicle is fitted with the system, a time counter calculates
the sum o
f the periods in STOP
mode during a journey. It resets
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 start usingthe 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 isneeded to assure control of a system.


Special cases: STOP modeunavailable

In this case, the "ECO"
warning lamp
flashes for a few seconds, then goes off.
This operation is per fectly normal.

213Driving

Going into engine START mode
The "ECO"warning lamp goes off and the engine star ts automatically:
-with a manual gearbox
, when you fullydepress the clutch pedal,-with the 6-speed electronic gearbox
system:●
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.

With a manual gearbox in STOP mode,if a gear is engaged without fullydepressing the clutch pedal,a warning lamp comes on or an aler t message is displayed asking you to depress the clutch pedal to restar t
the engine.
At any time, press the "ECO OFF"
switch todeactivate the system.
This is confirmed by the switch warning lamp coming on accompanied by the display of amessage.


Deactivation
In this case the "ECO"warning lamp flashes for few seconds, then goesof f.
This operation is per fectly 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 7 mph (11 k m/h) with the 6 -speed electronic
gearbox system,
- the electric parkin
g 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.

The system is reactivated automaticallyat every new star t using the key.
Reactivation

This system requires a specific battery with aspecial specification 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 malfunction with the s
ystem,
the "ECO OFF"switch warning lamp flashes,
then comes on continuously.
have it checked by a CITROËN dealer or a qualified workshop.
