The system adapts the gear change

conditions (e.g. slope, load) and driving style

(e.g. power demand, acceleration, braking).

The system never suggests:

Shortcuts for driving aids.

The display of a message on the instrument

panel conﬁrms the change of state.

If the function is deactivated while the engine is

in STOP mode, it will restart immediately.

Stop & Start

The Stop & Start function puts the engine

temporarily into standby - STOP mode - during

phases when the vehicle is stationary (e.g. red

lights, traﬃc jams). The engine automatically

restarts - START mode - as soon as the driver

indicates the intention of moving oﬀ again.

Primarily designed for urban use, the function

is intended to reduce fuel consumption and

exhaust emissions as well as the noise level

when stationary.

Operation

Depending on the driving situation and

the vehicle's equipment, the system may

recommend skipping one or more gears.

Gear engagement recommendations are

not to be considered mandatory. Indeed, the

conﬁguration of the road, the traﬃc density and

safety remain determining factors when choosing

the best gear. Therefore, the driver remains

responsible for deciding whether or not to follow

the system’s advice.

Associated indicator lamps

Function activated: engine on standby

(STOP mode)

Function deactivated or malfunction

Opening the bonnet

Before doing anything under the bonnet,

deactivate the Stop & Start system to avoid

any risk of injury caused by the engine

restarting automatically.

The function does not aﬀect the functionalities of

the vehicle, in particular the braking.

The system cannot be deactivated.

Deactivation/Reactivation

With an automatic gearbox, the system is

only active in manual operation.

By default, the function is activated when the

ignition is switched on.

fully depressed.

A time counter adds up the time spent in standby

during the journey. It is reset to zero every time

the ignition is switched on.

With an automatic gearbox:

– With the selector in mode D or M: with the

brake pedal released.

For more information on Driving

Special cases:

recommendations, particularly on ﬂooded

roads, refer to the corresponding section.

– With the selector in mode N and the brake

pedal released: with the selector at D or M.

– With the selector in mode P and the brake

pedal depressed: with the selector at R, N, D

or M.

The engine will not go into standby if the

conditions for operation are not met and in the

following cases:

– Steep slope (ascending or descending).

– Vehicle has not exceeded 6 mph (10 km/h)

since the last engine start (with the key or the

START/STOP button).

– Needed to maintain a comfortable temperature

in the passenger compartment.

– Demisting active.

Operation

Main conditions for operation

– With reverse gear engaged.

– The driver’s door must be closed.

– The driver's seat belt must be fastened.

– The level of charge in the battery must be

suﬃcient.

– The temperature of the engine must be within

its nominal operating range.

Special cases

The engine will restart automatically if the

conditions for operation are met again and in the

following cases:

– With a manual gearbox: vehicle speed

exceeds 2.5 mph (4 km/h).

– With an automatic gearbox, in mode N, vehicle

speed exceeds 0.6 mph (1 km/h).

In these cases, this indicator lamp ﬂashes

for a few seconds, then goes oﬀ.

In these cases, this indicator lamp ﬂashes

for a few seconds, then goes oﬀ.

– The outside temperature must be between

0°C and 35°C.

After the engine has restarted, STOP

mode is not available until the vehicle

has reached a speed of 5 mph (8 km/h).

Putting the engine into standby

(STOP mode)

The engine automatically enters standby mode

as soon as the driver indicates their intention to

stop:

– With a manual gearbox: with the gear lever

in neutral and the clutch pedal released.

– With an automatic gearbox: with the gear

selector in mode D or M, the brake pedal

depressed until the vehicle stops or the gear

selector in mode N, with the vehicle stationary.

Malfunctions

During parking manoeuvres, STOP mode

is not available for a few seconds after

coming out of reverse gear or turning the

steering wheel.

In the event of a fault with the system, this

warning lamp ﬂashes for a few moments

on the instrument panel, then remains on,

accompanied by the display of a message.

Have it checked by a CITROËN dealer or a

qualiﬁed workshop.

Restarting the engine (START mode)

The engine automatically restarts as soon as the

driver indicates the intention of moving oﬀ again:

Driving

The vehicle stalls in STOP mode

The tyre under-inﬂation detection cannot,

in any circumstances, replace the need

for vigilance on the part of the driver.

This system does not avoid the need to

regularly check the tyre pressures (including

the spare wheel), especially before a long

journey.

Snow chains

The system does not have to be

reinitialised after ﬁtting or removing snow

chains.

All of the instrument panel warning lamps come

on if there is a fault.

► Switch oﬀ the ignition then start the engine

again with the key or the "START/STOP" button.

Under-inﬂation alert

12 V battery

The Stop & Start system requires a

12 V battery of speciﬁc technology and

speciﬁcation.

All work must be carried out only by a

CITROËN dealer or a qualiﬁed workshop

This is signalled by the ﬁxed illumination

of this warning lamp, accompanied by an

audible signal and, depending on equipment, the

display of a message.

► Reduce speed immediately, avoid excessive

steering movements and avoid sudden braking.

► Stop the vehicle as soon as it is safe to do

so.

Driving with under-inﬂated tyres, particularly

in adverse conditions (heavy load, high

speed, long journey):

– worsens road-holding.

– lengthens braking distances.

– causes premature wear of the tyres.

– increases energy consumption.

Tyre under-inﬂation

detection

This system alerts the driver if one or more tyres

suﬀer a drop in pressure.

The inﬂation pressures deﬁned for the

vehicle can be found on the tyre pressure

label.

For more information on the Identiﬁcation

markings, refer to the corresponding section.

The loss of pressure detected may not

always cause visible deformation of the

tyre.

Do not rely on just a visual check.

The alert is raised when the vehicle is moving,

not when stationary.

► Using a compressor, such as the one in

the temporary puncture repair kit, check the

pressures of all four tyres when cold.

► If it is not possible to carry out this check

immediately, drive carefully at reduced speed.

► In the event of a puncture, use the

temporary puncture repair kit or the spare wheel

(depending on equipment).

It compares the information given by the wheel

speed sensors with reference values, which

must be reinitialised every time the tyre

pressures are adjusted or a wheel changed.

It takes into account the last values stored

during the reinitialisation request. It is therefore

essential that the tyre pressure is correct during

the operation. This operation is the driver’s

responsibility.

Checking tyre pressures

This check should be done monthly

when the tyres are "cold" (vehicle stopped for

1 hour or after a journey of less than 6 miles

(10 km) at moderate speeds).

Otherwise, add 0.3 bar to the pressures

shown on the label.

Driving too slowly may not ensure

optimum monitoring.

The alert is not immediately triggered in the

event of a sudden loss of pressure or tyre
