gearbox
, with the vehicle stationary and your foot on the brake, whenyou put the gear lever into neutral andrelease the clutch pedal.

Never refuel with the engine in STOPmode; you must switch off the ignition with the key or the START/STOP button.
When the engine is stopped automatically, the operation of certainvehicle systems, such as for example,braking, power steering... are modified. Take care.


Special cases: STOP mode notavailable
STOP mode is not invoked when:


- the driver's seat belt is not fastened,

- the bonnet is open,

- the vehicle has not exceeded 3 mph (5 km/h) since the last engine start,

- the vehicle has restarted less than10 seconds ago,

- the engine is needed to maintain acomfor table 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.

- th
e "AS&G"warning lamp is
flashing in the instrument panel.
This operation is perfectl
y normal.

The Stop & Star t (Auto Stop & Go) function puts the engine temporarily into standby during stops in the traffic (red lights, traffic jams, or other...). Theengine restarts automatically as soon as you want to move off. The restart takes place instantly, quickly and silently.

Fitting a battery not listed by CITROËN
introduces the risk o
f malfunction of the system.

Safety
Group of supplementary systems which helpyou to obtain optimum braking in complete safety in emergency situations:
- anti-lock braking system (ABS),
- electronic brake force distribution (EBFD).























Braking assistance systems


Anti-lock braking system
and electronic brake force
distribution

Linked systems which improve the stability and
manoeuvrability of your vehicle when braking,
in par ticular on poor or slippery surfaces.

Activation

The anti-lock braking system is active if the
vehicle speed is higher than 6 mph (10 km/h).
It is deactivated when the vehicle speed falls
below 3 mph (5 km/h).
The anti-lock braking system comes into
operation automatically when there is a risk of
wheel lock.
Normal operation of the ABS may make itself felt by slight vibration of the brake pedal.


Operating fault

y

If this warning lamp comes on, accompanied by
the indication on the instrument panel screen, it
indicates a malfunction of the anti-lock brakin
gsystem which could result in a loss of control of
the vehicle when braking.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or a qualified workshop assoon as possible.
When braking in an emergency, pressvery firmly without releasing thepressure.

If this warning lamp comes
on continuously it indicates a
malfunction of the anti-lock brakingsystem which could result in a loss of control of the vehicle on braking.
The two warning lamps comes on at the same time and the two warnings aredisplayed alternately in the instrumentpanel screen. When replacing wheels (tyres and rims), ensure that they conform to themanufacturer's recommendations.

Safety
Associated systems which guarantee the directional stability of the vehicle within the limits of the laws of physics:
- traction control (TCL),
- active stability control (ASC).

Traction control and active stability control
Traction control optimises traction to prevent
wheel spin, by acting on the brakes of the
driving wheels and on the engine.
Active 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.

Activation

These systems are activated automaticallyeach time the vehicle is started.
The illumination o
f this warning lamp
in the instrument panel indicates
that the ASC and TCL systems are deactivated.


Deactivation

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft ground, ...), it may be advisable to deactivate
the ASC system, so that the wheels can movefreely and regain grip.
This is indicated b
y flashing of this symbol on the instrument panel screen.






















Trajectory control systems
)Press this button, located to the left of thesteering wheel, until the symbol appears in
the instrument panel screen.

Operation

They operate when the vehicle speed is higher
than 10 mph (15 km / h).
They come into operation in the event of a grip
or trajectory problem.

Safety
Reactivation Operating fault
The illumination of one of these warning lamps accompanied by a message in the instrument panel screen indicates a malfunction of these
systems.
Contact a CITROËN dealer or a qualified
workshop to have the ASC/ TCL systemschecked.
The ASC/TCL systems offer exceptional safety in normal driving, but this should not encourage the driver to take extra risks or drive at high speed.
The correct functioning of these systems depends on obser vation of themanufacturer's recommendations on:


- wheels (tyres and rims),

- braking components,

- electronic components,

- assembly and repair procedures.
After an impact, have these systems checked by a CITROËN dealer or a qualified workshop.

)Press this button again to reactivate theASC and TCL systems.
When the warning lamp goes off, this indicates
the reactivation of the ASC and TCL systems.
