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 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 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.
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). CarM an uals 2 .c o m

Range
(miles or km)Distance that can still be travelled with the
fuel remaining in the tank (based on the
average fuel consumption over the last few miles
(kilometres) travelled).
This value may vary following a change in driving
style or terrain, leading to a significant change in
current fuel consumption.
When the range falls below 19 miles (30
km),
dashes are displayed.
After filling with at least 5 litres of fuel, the range
is recalculated and is displayed if it exceeds 62
miles (100
km).
Dashes appearing permanently in place of
numbers while driving indicates a malfunction.

Charging
This page allows you to programme deferred
charging.
For more information on Charging the traction
battery (Rechargeable hybrid), refer to the
corresponding section.
e-SAVE
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 ON

, then
select the electric range to be reserved ( 6 miles
(10 km), 12 miles (20 km) or the full range
MAX).
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.
i-Toggles
This system is an additional touch screen
associated with the PEUGEOT i-Connect
Advanced. It is designed to provide a
personalised display of shortcuts to applications
or presets.
By default, it directs you to the main applications:
Media, Climate, Navigation, Phone, Mirror
Screen, etc.
The shortcuts can be replaced by: radio preset,
temperature preset, pre-selected destination,
pre-selected contact, pre-selected smartphone,
etc.

version).
The selection of the Sport mode deactivates the
Stop & Start function.
Coasting mode
Depending on version and engine, with
the gear selector in mode D, in
Eco and
Normal modes, gradually and fully releasing
the accelerator pedal allows free-wheeling
which can save fuel.
A drop in engine speed is normal (rev counter
at idle, drop in engine noise).
With 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.
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.
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.
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. CarM an uals 2 .c o m

101
Driving
6Do 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.
Gear shift indicator
(Depending on engine)
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.
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. CarM an uals 2 .c o m
