another if the vehicle speed and engine speed
conditions permit.
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.

Driving
6With Rechargeable hybrid
engines
Whenever the ignition is switched on, Electric
driving mode is selected by default.
Electric
Allows driving using 100% electrical energy.
The maximum speed is approximately 84 mph
(135
km/h).
When starting the vehicle, if the conditions do
not allow the activation or retention of Electric
mode, the message "Electric mode currently
unavailable" is displayed on the instrument
panel. The vehicle automatically changes to
Hybrid mode.
Conditions of activation
–

Adequate battery charge level. Charging
the vehicle after each drive is therefore

Active Suspension Control function.
For more information on Active Suspension
Control, refer to the corresponding section.
In the event of multiple starts of the
internal combustion engine without a
sufficient rise in temperature, Electric mode
may be temporarily unavailable (natural
phenomenon of dilution of fuel in oil). The
message "Electric mode unavailable:
automatic operation in progress " then
appears on the instrument panel.
To regain normal electrical operation, drive
approximately 50
miles (80 km) in "motorway"
conditions or approximately 125
miles
(200
km) in urban conditions.
This phenomenon does not cause any
mechanical or electrical damage. It can occur
several times in the life of the vehicle.
Hybrid
To optimise the vehicle's fuel consumption by
managing the alternating or simultaneous
operation of the two types of engine ,
depending on driving conditions and driving
style.
In Hybrid mode, it is possible to drive in 100%
electric mode if the battery charge level is
sufficient and acceleration requirements are
moderate.
Depending on equipment, Hybrid mode
is combined with Normal mode of the
Active Suspension Control function.
For more information on Active Suspension
Control, refer to the corresponding section.
Sport
To obtain more dynamic driving in order to
benefit from the maximum performance of the
vehicle.
Electric power is used to supplement the petrol
engine as long as there is energy left in the
battery.
Depending on equipment, Sport mode is
combined with Sport mode of the Active
Suspension Control function.
For more information on Active Suspension
Control, refer to the corresponding section.
PSE (PEUGEOT Sport Engineered)
The electrical energy is used to
supplement the petrol engine or recharge
the traction battery, depending on the type of

the Active Suspension Control function.
To favour flexible shock absorption improving
driving comfort on poor surfaces.
For more information on Active
Suspension Control , refer to the
corresponding section.
4WD (4-wheel drive)
(Depending on version)
Improves the vehicle's grip at low and moderate
speeds by driving all 4 wheels continuously.
4WD mode (4-wheel drive) is especially
suited to driving on snow-covered roads and
difficult terrain (e.g.
mud, sand) as well as ford
crossings, at moderate speed.
Depending on the driving conditions and the
battery charge level, 4WD mode may be 100%
electric.
If the system does not detect a situation of wheel
slipping or poor grip after 300 metres of driving, it
switches to Hybrid mode.
This mode will be even more effective if the vehicle is fitted with suitable tyres,
such as winter tyres.
The grip can be improved up to 84 mph
(135

km/h) using the electric motors; above this
speed, the vehicle is driven by the front wheels
only.
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:
–

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 hill start assist function cannot be deactivated. However, using the parking
brake to immobilise the vehicle interrupts its
operation.
Operation

Facing uphill, with the vehicle stationary,
the vehicle is held for a short time when the
driver releases the brake pedal:
–

If mode
D or M is selected on an automatic
gearbox.


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.
Malfunction
If the event of a malfunction, these
warning lamps light up on the
instrument panel, accompanied by the display of
a message.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
