2. Electric motor
3. 6-speed or 7-speed electric dual-clutch
automatic gearbox (e-DCS6/7)
4. 48 V traction battery
5. 12 V accessory battery
6. DC/DC converter
7. Belt starter
The 48
V hybrid technology requires no
connection to charge the traction battery.
The Hybrid system does not operate
continuously, but is activated according to
the state of the vehicle, the state of charge
of the traction battery, the thermal comfort of
the passenger compartment (switching on
the heating or air conditioning), the driving
conditions (acceleration, deceleration, braking,
engine start-up) and the road conditions (uphill,
downhill): –

The vehicle always starts with the petrol
engine to ensure the efficiency of the catalytic
converter and the availability of the brake assist.
–

In normal driving, the petrol engine and
electric motor work together or separately to
optimise fuel consumption and electrical energy
or to charge the traction battery
.
–
During the acceleration phases, the electric
motor provides an additional boost to reach
the torque needed as fast as possible and to
improve the acceleration at low speed.
–

During the deceleration phases, the electric
motor charges the traction battery
, using the
inertia of the vehicle.
– The driving in all-electric is possible for parking
manoeuvring, for 20
mph (30 km/h) speed zones
in city, on urban and country roads with smooth
driving and on motorways in slight deceleration
or downhill.
The electric motor is integrated into the
automatic gearbox.
The DC/DC converter provides the link between
the 12
V accessory power supply and the 48 V
traction power supply.
The belt starter restarts the petrol engine after
driving in all-electric.

and that of the electric motor, which drive the
front wheels (traction).
The engine and the motor can operate
alternately or simultaneously, according to the
driving mode selected and the driving conditions.

Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise
the vehicle's energy consumption (fuel and/or
electricity) and CO
2 emissions.
Optimise your use of the gearbox
With a manual gearbox, move off gently and
change up promptly. While accelerating, change
up early.
With an automatic gearbox, favour automatic
mode. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift indicator prompts you to engage
the most suitable gear. Whenever this indication
is displayed on the instrument panel, follow it
straight away.
With an automatic gearbox, this indicator
appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles, use
engine braking rather than the brake pedal and
press the accelerator gradually. These practices
help to save on energy consumption, reduce
CO
2 emissions and decrease general traffic
noise.
With a hybrid engine, engine braking is more
efficient. Anticipate slowing down as much as
you can and, if possible, favour deceleration with
engine braking in order to charge the traction
battery, to increase all-electric driving and to
reduce fuel consumption. With an EAT8 gearbox, with the gear selector in
mode
D, and except in Sport mode, favour "free-
wheeling" by gradually lifting your foot fully off
the accelerator pedal in order to save fuel.
When the traffic is flowing smoothly, select the
cruise control.
Control the use of electrical equipment
Before moving off, if the passenger compartment
is too warm, ventilate it by opening the windows
and air vents before using the air conditioning.
At speeds above 31
mph (50 km/h), close the
windows and leave the air vents open.
Consider using equipment that can help keep
the temperature in the passenger compartment
down.
Unless automatically regulated, switch off the air
conditioning as soon as the desired temperature
has been reached.
Switch off the demisting and defrosting functions,
if they are not managed automatically.
Switch off the heated seat and heated steering
wheel as soon as possible.
Adapt your use of the headlamps and/or
foglamps to the level of visibility, in accordance
with current legislation in the country in which
you are driving.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The
vehicle will warm up much faster while driving. As a passenger, avoid connecting your
multimedia devices (e.g.
film, music, video
game) to help reduce the consumption of energy.
Disconnect all portable devices before leaving
the vehicle.
Limit the causes of excess consumption
Spread loads throughout the vehicle. Place the
heaviest items in the boot as close as possible to
the rear seats.
Limit the loads carried in the vehicle and
minimise wind resistance (e.g.
roof bars, roof
rack, bicycle carrier, trailer). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit
summer tyres.
Comply with the servicing instructions
Check tyre pressures regularly, with the tyres
cold, referring to the label in the door aperture on
the driver's side.
Carry out this check in particular:
–

before a long journey
.
–

at each change of season.
–


after a long period out of use.
Do not forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g.

engine
oil, oil filter, air filter, passenger compartment
filter, etc.). Observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
has a fault, your vehicle will emit pollution. Visit

10
Eco-driving
a PEUGEOT dealer or a qualified workshop
as soon as possible to restore your vehicle's
nitrogen oxide emissions to legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, to avoid overflow.
You will only see the fuel consumption of your
new vehicle settle down to a consistent average
after the first 1,900 miles (3,000 kilometres).
Optimising the driving range of electrified
vehicles
The vehicle's consumption of electrical energy
greatly depends on the route profile, speed and
driving style, as well as the use of the heating/air
conditioning.
Favour the ECO and CHARGE zones of the
power indicator by driving smoothly and at a
steady speed.
Hybrid vehicles
Maximise the vehicle's inertia by releasing the
accelerator pedal so that the vehicle slows
down by itself (e.g.
when driving downhill or
approaching a traffic light).
When the accelerator pedal is released, provided
that the slider on the power indicator in the
instrument panel is still moving in the CHARGE
zone, energy recovery is optimal.
Energy recovery makes it possible to make
efficient use of the "passive" phases of driving
(deceleration).
The recovered energy is used to recharge the
traction battery and is then used for all-electric
driving or further acceleration. When the traction battery is almost full, the
energy recovery is gradually reduced.
Rechargeable hybrid vehicles
Connect the vehicle as soon as possible.
Anticipate slowing down as much as possible
and, if possible, favour decelerations with the
regenerative braking function activated (power
indicator in the
CHARGE zone).
With the vehicle connected, carry out
temperature pre-conditioning before setting off.
To optimise consumption during a journey:
► Program a destination into the vehicle’ s GPS
navigation system.
►

Select the
Hybrid driving mode.
►

Make sure that the battery charge level is
close to maximum.
►


Do not use the e-Save function while driving.
►


Use the heating/air conditioning system
wisely

.
Electric vehicles
Program a destination into the vehicle's GPS
navigation system to optimise consumption
during a journey.
Anticipate the need to slow down, and brake
smoothly, whenever possible using engine
braking with the regenerative braking function,
which will move the power indicator into the
"CHARGE" zone.
Use the air conditioning rather than the heating
to demist the passenger compartment.

e-SAVE (Rechargeable hybrid)
The e-SAVE function makes it possible to
reserve all or part of the electrical energy of the
traction battery to be used later during a journey
(e.g.
passing through an urban area or an area
reserved for electric vehicles).
►

Activate
the function by pressing Set e
- SAVE,
then select the electric range to be reserved
(6 miles (10 km), 12 miles (20 km) or the full

Activation of the function is confirmed by the lighting of this indicator lamp on the
instrument panel and the indication of the energy
reserve in miles or kms.
►

T

o use the energy reserve, choose the
Electric driving mode in the mode selector.
If the requested range exceeds the
available range (not recommended), the
internal combustion engine starts to recharge
the traction battery up to the requested
threshold. This leads to excessive fuel
consumption.

deactivate the function (the button lights up when
the function is activated).
D on the instrument panel is replaced with B.
The system status 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.
With the brake pedal
When the brake pedal is depressed, the
intelligent braking system automatically recovers
some of the energy and uses it to recharge the
traction battery.
This energy recovery also reduces use of the
brake pads, thereby limiting their wear.
The driver may experience a different sensation when depressing the brake
pedal compared to a vehicle without
regenerative braking.
Driving modes
The driving modes available depend on the engine and equipment of the vehicle. Driving modes are selected using the following
control:




► Press the control to display the modes on the
