The driver changes gear using the steering-mounted controls.

B. Driving in automatic mode with regenerative braking function (Rechargeable hybrid)

Press this button to activate the regenerative braking function.

The gearbox also manages braking when the accelerator pedal is released.

► In mode N, with your foot on the brake pedal, push without passing the point of resistance:

• Forwards, mode R is selected.
• Backwards, mode D is selected.

Release the selector fully after each push; it will then return to its initial position.

Special cases

To avoid mode N (quick change from D to R and back again):

► In mode R, push backwards past the point of resistance, mode D is selected.

► In mode D, push forwards past the point of resistance, mode R is selected.

► To return to mode N, push without passing the point of resistance.

Steering-mounted controls

(Depending on equipment)

In mode M or D, the steering-mounted control paddles can be used to change gear manually.

They cannot be used to select neutral or to engage or disengage reverse gear.

► Pull the "+" or "-" paddle towards you and release to shift up or down a gear, respectively.

Electric motor

The electric motor included in the automatic gearbox, which is used for the first start, provides 12 V power supply via the DC/DC converter and provides electric assistance to the petrol engine.

The electric motor has the following features:

- Provide an additional torque to the gearbox, optimising the performance of the petrol engine.

- Recover the kinetic energy of the deceleration phases, converting it into electrical energy, which can be used for traction or for the power supply of electrical accessories installed on the vehicle.

- Recharge the 48 V traction battery when the state of charge is too low.

- Provide all-electric driving only.

These features are achieved through the following functions set of automatic operating mode:

• e-Boost.
• e-Creeping.
• e-Launch.
• e-Queueing.
• e-Parking.

A manual operating mode is also available to activate/deactivate the restart of the petrol engine while driving: the e-Auto mode.

When mode P or N is selected on the automatic gearbox, the noise level in the engine compartment may increase due to the start of the charging phase of the traction battery: this is normal and does not represent a malfunction.

Information displayed on the instrument panel

When the ignition is switched on, the gearbox status is displayed on the instrument panel:

P Parking

R Reverse

N Neutral

D Automatic forward gear (Hybrid)

M1...6 Manual forward gear (Hybrid)

D1...7 Automatic forward gear (Rechargeable hybrid)

B1...7 Automatic forward gear with regenerative braking function (Rechargeable hybrid)

The gear engaged is also displayed in Sport mode.

However, in all-electric driving, the gear engaged is not indicated.

The state of the gearbox remains displayed on the instrument panel for a few seconds after switching off the ignition.

Operation

Only appropriate mode change instructions are validated.

With the engine running, if it is necessary to depress the brake pedal to change modes, an alert message will be displayed on the instrument panel.

With the engine running and the brakes released, if R, D or M is selected, the vehicle moves off, even without pressing the accelerator pedal.

Never depress the accelerator and brake pedals at the same time - risk of damage to the gearbox! If you open the driver's door while mode N is engaged, an audible signal will sound and mode P will be engaged. The audible signal stops when the driver's door is closed.

At speeds below 3 mph (5 km/h), opening the driver's door will engage mode P - risk of sudden braking! In the event of battery failure, it is essential to place the chock(s) supplied with the tool kit against one of the wheels to immobilise the vehicle.

Special aspects of automatic mode

These functions respond to common driving situations where the electric motor is available to provide additional power or zero-emission driving.

These functions are only available if the traction battery is sufficiently charged.

These five functions cannot be deactivated.

e-Launch

With the petrol engine off, this function allows the vehicle to run in electric mode without affecting performance.

By depressing the accelerator pedal, the vehicle starts to drive as soon as the mode D or R of the automatic gearbox is selected.

e-Creeping

With the petrol engine off, by releasing the brake pedal, this function allows the vehicle to be moved forward or backward in electric mode without having to depress the accelerator pedal, as soon as the mode D or R of the automatic gearbox is selected.

e-Queueing

This function makes it possible to follow a queue of vehicles with several stops followed by restarts of the vehicle, using the e-Creeping, e-Launch and electric driving modes.

e-Parking

This function allows parking manoeuvres to be carried out at reduced speed with the help of the electric motor when the mode D or R of the automatic gearbox is selected.

e-Boost

This function allows simultaneous operation of the petrol engine and the electric motor, combined with the automatic gearbox.

By fully depressing the accelerator pedal ("kick-down" function), when the traction battery is fully charged, it is possible to exceed the torque of the petrol engine alone, thanks to the additional torque provided by the electric motor.

Repeated use of the brake pedal causes the restart of petrol engine to provide braking assistance.

Special aspects of manual mode

The gearbox only changes from one gear to another if the vehicle speed and engine speed conditions permit.

The petrol engine can also be switched off in manual mode when stopped in traffic or when the accelerator pedal is released.

For hybrid vehicles, the all-electric potential of the driving mode used (Normal or Eco) is also retained.

For rechargeable hybrid vehicles, the all-electric potential of the driving mode used (Hybrid or Electric) is also retained.

Using the steering wheel paddles also causes the restarting of petrol engine.

If high traction is required, the driver can deactivate the e-Auto mode using the touch screen application.

Regenerative braking (Brake function)

The regenerative braking function emulates engine braking, slowing the vehicle with no need to depress the brake pedal. When the driver releases the accelerator pedal, the vehicle slows down more quickly.

The energy recovered when the accelerator pedal is released is used to partially recharge the traction battery.

This partial recharging has no effect on 6 the charge level indicator.

The resulting deceleration of the vehicle does not cause the brake lamps to come on.

► From mode D, press button B to activate/ deactivate the function.

D on the instrument panel is replaced with B.

The state of the function is not saved when the ignition is switched off.

In some situations (e.g. battery full, extreme temperatures), the amount of regenerative braking may be temporarily limited, resulting in less deceleration.

The driver must remain alert to traffic conditions and must always be ready to use the brake pedal.

Regenerative braking using the brake pedal

Energy recovery can also be produced by depressing the brake pedal in order to partially recharge the traction battery, without affecting the charge level indicator.

Starting the vehicle

► Fully depress the brake pedal.

► Start the petrol engine by depressing the brake pedal until the engine is running at a stabilised engine speed.

► With your foot on the brake pedal, push once or twice backwards to select automatic mode D, or forwards to shift into reverse gear R.

► Release the brake pedal.

► Accelerate gradually to automatically release the electric parking brake.

The petrol engine may stop after the first start if operating conditions allow (e.g. state of charge of the traction battery, external temperature, efficiency of the catalytic converter, torque demand, selected driving mode, thermal comfort of the passenger compartment).

Then, the vehicle moves off immediately in all-electric (e-Launch function).

Switching the vehicle off

Regardless of the current gearbox mode, mode P is immediately engaged automatically when the ignition is switched off.

However, in mode N, mode P will be engaged after a delay of 5 seconds (time to enable freewheeling mode).

Check that mode P has been engaged and that the electric parking brake was applied automatically; if not, apply it manually.

The corresponding indicator lamps on the gear selector and the electric parking brake control must be on, as well as the indicator lamps on the instrument panel.

Gearbox malfunction

This warning lamp comes on, accompanied by an audible signal and the display of a message.

Go to a PEUGEOT dealer or a qualified workshop.

Do not drive faster than 62 mph (100 km/h), keeping to the speed limit.

Switching of the gearbox to back-up mode

Depending on the malfunction, the gearbox only shifts in odd or even gears, locks in one gear or loses some gears.

For hybrid vehicles, the paddles on the steering wheel do not work and mode M is no longer accessible.

You may feel a significant jolt on engaging reverse gear. This will not damage the gearbox.

Selector malfunction

Minor malfunction

This warning lamp comes on, accompanied by the display of a message and an audible signal.

Drive carefully.

Go to a PEUGEOT dealer or a qualified workshop.

In some cases, the selector indicator lamps may no longer come on, but the gearbox state is still displayed on the instrument panel.

Major malfunction

This warning lamp comes on, accompanied by the display of a message.

You must stop the vehicle.

Stop as soon as it is safe to do so and switch off the ignition.

Contact a PEUGEOT dealer or a qualified workshop.
