6Emergency braking
If depressing the brake pedal fails to provide
effective braking or in exceptional circumstances
(e.g. driver unwell, assisted driving), the vehicle
can be braked by sustained pulling on the
electric parking brake control. Braking continues
for as long as the control is kept pulled, and
ceases when the control is released.
The ABS and DSC systems stabilise the vehicle
during emergency braking.
If emergency braking malfunctions, the message
"Parking brake fault" will be displayed on the
instrument panel.
If the ABS and DSC systems
malfunction, indicated by lighting
one or both warning lamps on the instrument
panel, the vehicle’s stability is no longer ensured.
►

In this case, ensure the vehicle's stability by
successive and repeated "pull-release" actions
on the electric parking brake control until the
vehicle comes to a complete stop.

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
D1...8 Automatic forward gear
B1...8 Automatic forward gear with
regenerative braking function activated
M1...8 Manual forward gear
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
The gearbox selects the gear that provides
optimal performance based on ambient
temperature, road profile, vehicle loading and
driving style.
For maximum acceleration, press the accelerator
fully down (kick-down). The gearbox changes
down automatically or holds the selected gear
until the maximum engine speed is reached.
Steering mounted controls allow the driver to
temporarily select a gear, if the vehicle speed
and engine speed conditions permit.
Special aspects of manual mode
The gearbox only changes from one gear to
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.

105
Driving
6This partial recharging has no effect on 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.

107
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
recommended. Electric

mode is available as
long as there is power left in the battery.
–

Outside temperature between approximately
-5°C and 45°C.
Manually exiting the mode
►


Fully depress the accelerator pedal, or
►


Select another mode.
In case of non-use of the vehicle for a
long period (several months), a restart of
the petrol engine may occur even if the
battery is charged.
Depending on equipment, Electric mode
is combined with Normal mode of the
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
driving.
This mode is optimised with specific settings
which make the most of the dynamic
performance of this vehicle (power steering,
accelerator pedal sensitivity, ESC).
Comfort
(Depending on equipment)

108
Driving
Combines Hybrid mode and Comfort mode 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.

6Gear shift indicator
This system is designed to reduce fuel
consumption by recommending the most suitable
gear.
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.
The system cannot be deactivated.
The system is only active in mode M of
the automatic gearbox.
The information appears on the instrument panel, in the form of an arrow
and the recommended gear.
The system adapts the gear change instructions according to the driving
conditions (e.g.
slope, load) and driving style
(e.g.
power demand, acceleration, braking).
The system never suggests:
–

engaging first gear
.
–

engaging reverse gear
.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stationary (e.g.
