Hill start assist

This system keeps the vehicle briefly stationary

(for approximately 2 seconds) when making a

hill start, while you transfer your foot from the

brake pedal to the accelerator pedal.

The system is only active when:

Stop & Start (Petrol)

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.

Facing uphill, with the vehicle stationary, the

vehicle is held for a short time when the driver

releases the brake pedal:

– If first gear or neutral is engaged on a manual

gearbox.

– If mode D, M or L is selected on an automatic

gearbox.

– If mode D or C is selected on the drive

selector.

– The vehicle is completely stationary, with

your foot on the brake pedal.

– Certain slope conditions are met.

– The driver’s door is closed.

Do not leave the vehicle while it is

being held temporarily by hill start

assist.

If someone needs to get out of the vehicle

with the engine running, apply the parking

brake manually. Then check that the parking

brake indicator lamp and the P indicator

lamp in the electric parking brake control are

on fixed.

The function does not affect the functionalities

of the vehicle, in particular the braking.

Deactivation/Reactivation

The function is activated by default when the

ignition is switched on.

To deactivate/reactivate the function:

The hill start assist function cannot be

deactivated. However, using the

parking brake to immobilise the vehicle

interrupts its operation.

Facing downhill, with the vehicle stationary

and reverse gear engaged, the vehicle is held

for a short time when the driver releases the

brake pedal.

since the last engine start.

– Electric parking brake applied or being

applied.

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: when you place

the gear lever in neutral and release the clutch

pedal.

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.

After the engine has restarted, STOP

mode is not available until the vehicle

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

– With an automatic gearbox: with the gear

selector in mode D or M, when the brake pedal

is depressed until the vehicle stops or when the

mode N is selected, with the vehicle stationary.

During parking manoeuvres, STOP

mode is not available for a few

seconds after coming out of reverse gear or

turning the steering wheel.

Driving on flooded roads

Before entering into a flooded area,

it is strongly recommended that you

deactivate the Stop & Start system.

For more information on Driving

recommendations, particularly on flooded

roads, refer to the corresponding section.

Time counter

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.

Restarting the engine (START mode)

The engine automatically restarts as soon as

the driver indicates the intention of moving off

again:

With a manual gearbox: when the clutch pedal

is fully depressed.

Driving

With an automatic gearbox:

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

brake pedal is released.

– With the selector in mode N and the brake

pedal released: when the mode D or M is

selected.

– With the selector in mode P and the brake

pedal depressed: when the mode R, N, D or M

is selected.

The vehicle stalls in STOP mode

All of the instrument panel warning lamps

come on if there is a fault.

►ꢀ Switch off the ignition then start the engine

again.

Using the steering wheel paddles also

causes the restarting of petrol engine.

The e-Auto mode cannot switch off the petrol

engine in the following cases:

– The state of charge is less than 30% of the

traction battery energy.

– There is a need for vacuum brake assist

depending on the altitude.

– Maintaining thermal comfort in the

passenger compartment (heating, air

conditioning, demisting/defrosting).

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.

– When the reverse gear is engaged.

Special cases

The engine will restart automatically if the

conditions for operation are met again and in

the following cases:

– Some specific conditions (braking assistance,

air conditioning setting, etc.).

– 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.

Deactivation/Reactivation

By default, the function is activated when the

ignition is switched on.

e-Auto mode (Hybrid)

The petrol engine stops when low power or

torque is required and in stabilised conditions.

The petrol engine is restarted by the belt

starter.

The "e-Auto OFF" control on the dashboard

activates/deactivates the e-Auto mode.

The e-Auto mode can switch off the petrol

engine in the following cases:

– When the operating strategies permit.

– Vehicle speed up to 90 mph (145 km/h).

– When the driver releases the accelerator

pedal in stabilised conditions or in deceleration.

– During the stop phases.

Restarting is only achieved by the belt starter

until the torque demand is available, if the

traction battery is sufficiently charged. When

the torque demand is insufficient, the petrol

engine restarts.

Malfunctions

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.

►ꢀ Press the dashboard button.

The display of a message on the instrument
