Driving
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.
If an LED comes on under the interior rear view
mirror, visible from outside the vehicle, this
confirms that you are driving in Electric mode
(depending on country of sale).
The LED can be deactivated by inserting the tip of a paper clip or other similar
object into the hole located underneath the
interior rear view mirror.
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)

Gear efficiency indicator
This system helps reduce fuel consumption by
recommending the most appropriate 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.
With an automatic gearbox, the system is
only active in manual operation.
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.
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.
The function does not affect the functionalities of
the vehicle, in particular the braking.

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
PEUGEOT
dealer or a qualified workshop
Under-inflation detection
This system alerts the driver when one or more tyres have a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
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 the last values

stored during
the

reinitialisation request into account. It is
therefore essential that the tyre pressure is
correct during the operation. This operation is
the driver’s responsibility.
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.
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.
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.
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.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
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.
