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.

Driving
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.
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.
Deactivation/Reactivation
By default, the function is activated when the
ignition is switched on.
It is configured in the ADAS touch screen
application.
or
Direct access to the Shortcuts for driving aids .
The display of a message on the instrument
panel confirms the change of state.
If the function is deactivated while the engine is
in STOP mode, it will restart immediately.

7Compatibility of fuels
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol
respectively.

Diesel fuels conforming to the EN590, EN16734
and EN16709 standards and containing up to
7%, 10%, 20% and 30% fatty acid methyl ester
respectively. The use of B20 or B30 fuels, even
occasionally, imposes special maintenance
conditions referred to as "Arduous conditions".

Paraffinic Diesel fuel conforming to the EN15940
standard.
The use of any other type of (bio)fuel (e.g. pure or diluted vegetable or animal
oils, domestic fuel) is strictly prohibited - risk
of damaging the engine and fuel system!
The only fuel additives authorised for use are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the
formation of paraffins in summer-type Diesel fuels could prevent the engine from operating
correctly
. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50 % full.
At temperatures below -15 °C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity: approximately 62
litres (Petrol), 55 litres (Diesel) or 43 litres
(Rechargeable hybrid).
Reserve level: approximately 6 litres.
Low fuel level
When the low fuel level is reached, this
warning lamp lights up on the instrument
panel, accompanied by the display of a message
and an audible signal. When it first comes on,
about 6 litres of fuel remain.
Until sufficient fuel is added, this warning lamp
appears every time the ignition is switched on,
accompanied by the message and the audible
signal. When driving, this message and audible
signal are repeated with increasing frequency as
the fuel level drops towards 0.
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of fuel
(Diesel), refer to the corresponding section.
A small arrow by the warning lamp indicates which side of the vehicle the
fuel filler flap is located on.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Any addition of fuel must be in quantities of at
least 10 litres, in order to be registered by the
fuel gauge.
Opening the filler flap may create a noise caused
by an inrush of air. This vacuum is entirely
normal, resulting from the sealing of the fuel
system.
The filler cap is built into the filler flap or must be
unscrewed (depending on version).
To refuel in complete safety:
►

Always switch off the engine.

146
Practical information

► To open the filler flap, press the flap opening
button for more than 2 seconds or, with the
vehicle unlocked, press the rear of the filler flap
(depending on version).
Rechargeable hybrid vehicles
After pressing the button on the
dashboard, the filler flap may not open for
several minutes. A sound is emitted when the
filler flap opens.
If the flap becomes stuck, press and hold
the button on the dashboard for more than
3

seconds.


► Select a pump that delivers the correct fuel
type for the vehicle's engine (see a reminder
label on the inside of the filler flap).
►

T
urn the filler cap to the left, remove it
and place it on its support on the filler flap
(depending on version).
►

Insert the filler nozzle and push it in as far as
possible before starting to refuel (to minimise the
risk of splashing).
►

Do not continue after the nozzle’

s third cut-
out. Doing so may cause malfunctions.
►

Put the filler cap back in place and turn it to
the right (depending on version).
►


Push the fuel filler flap to close it.
The vehicle is fitted with a catalytic converter,
which helps to reduce the level of harmful
emissions in the exhaust gases.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, allowing only
unleaded petrol nozzles to be inserted.
If you have put in the wrong fuel for
the vehicle, you must have the fuel
tank drained and filled with the correct fuel
before starting the engine.
Misfuel prevention (Diesel)
(Depending on country of sale.)
This mechanical device prevents filling the tank
of a Diesel vehicle with petrol.
Located in the filler neck, the misfuel prevention
device is visible when the filler cap is removed.
Operation

147
Practical information
7When a petrol filler nozzle is introduced into the
fuel filler neck of a Diesel vehicle, it comes into
contact with the flap. The system remains closed
and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
The misfuel prevention device does not prevent filling with a jerrycan, regardless
of the fuel type.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Before travelling abroad, it is advisable to
check with a PEUGEOT dealer if the vehicle
is suitable for the distribution equipment of the
countries visited.

Practical information
7Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the " MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).
