Driving
For Diesel engines, when the temperature is
below zero and/or the engine is cold, starting will
only occur once the preheating warning lamp is
off.
If this warning lamp comes on after
pressing the "START/STOP" button:
►

Keep the pedal fully depressed and do not
press the "

START/STOP" button again until the
engine is running.
If one of the starting conditions is not met, a
message is displayed.
In some circumstances, a message indicates
that it is necessary to turn the steering wheel
while pressing the " START/STOP" button to
assist unlocking of the steering column.
With petrol engines , after a cold start,
preheating the catalytic converter can
cause noticeable engine vibrations for
anything up to 2 minutes while stationary with
the engine running (accelerated idle speed).
If the engine stalls, release the clutch
pedal and fully depress it again, the
engine will restart automatically.
Starting hybrid vehicles
► Fully depress the brake pedal and press
briefly on the START/STOP button.
► Keep you foot on the pedal until this
indicator lamp comes on, indicating the
activation of the hybrid system (confirmed by an
audible signal).
By default, the system starts in ELECTRIC
mode.
Depending on certain parameters (battery
charge level or exterior temperature), the system
determines whether it is necessary to start the
petrol engine.
It is possible to change the driving mode at any
time using the mode selector.
When the vehicle starts in electric mode,
it makes no noise.
Pay particular attention to pedestrians and
cyclists who may not hear the vehicle coming
despite the pedestrian horn.
Switching off
► Immobilise the vehicle, with the engine at
idle.
►

With a
manual gearbox, ideally put the gear
lever into neutral.
►

With an
automatic gearbox, ideally select
mode
P or N.
►

Press the "
START/STOP" button..
►

For hybrid vehicles, before leaving the
vehicle, check that the

READY warning lamp is
switched off.
In some circumstances, it is necessary to turn
the steering wheel to lock the steering column.
On certain versions with an automatic gearbox
(EAT6 / EAT8), the steering column does not
lock, but the gearbox locks in mode P.
If the vehicle is not immobilised, the
engine will not switch off.
With the engine off, the braking and
steering assistance systems are also cut
off - risk of loss of control of the vehicle!
Never leave your vehicle with the
electronic key still inside.
Switching on the ignition
without starting the engine


With the electronic key in the passenger
compartment, pressing the “ START/STOP”
button, without pressing any of the pedals ,
allows the ignition to be switched on without
starting the engine.
►

Press this button
again to switch off the
ignition and allow the vehicle to be locked.
Key not detected
Back-up starting
A back-up reader is fitted to the steering column,
to enable the engine to be started if the system
fails to detect the key in the recognition zone, or
if the battery in the electronic key is discharged.


► Place and hold the remote control against the
reader.
► With a manual gearbox, place the gear lever
in neutral, then fully depress the clutch pedal.
► With an automatic gearbox, select mode P,
then fully depress the brake pedal.
► Press the "START/STOP" button.

Practical information

► With the vehicle unlocked, press the rear
edge of the filler flap to open it (the filler cap is
built in).
►

T
ake care to select the pump that delivers the
correct fuel type for the vehicle's engine (see a
reminder label on the inside of the filler flap).
►

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


Fill the tank.
Do not continue past the 3rd cut-off of the
nozzle; as this may cause malfunctions.
►

Push the filler flap to close it.
The vehicle is fitted with a catalytic converter

, a
device 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 introduced.
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 appears when the filler cap is removed.
Operation

When a petrol filler nozzle is inserted 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.
It remains possible to use a fuel jerrycan
to fill the tank.
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.
Hybrid system
Electrical system
The electrical system of the hybrid system is
identified by orange cables and its elements are
marked with this symbol:

The hybrid engine uses a voltage of between 240 V and 400 V. This system
may be hot during and after switching off the
ignition. Observe the warning messages on
the labels in the vehicle, especially in the flap.
Any work on or modification to the vehicle's
electrical system (battery, connectors, orange
cables and components visible from inside or
outside) is strictly prohibited due to the risk of
serious burns or electrical shock that can lead
to death.
In the event of a problem, always contact a
PEUGEOT dealer or a qualified workshop.


This label is intended solely for use by firefighters responding to an incident
involving the vehicle and for maintenance
technicians.
In the event of an accident or impact
The electrical system or the battery
may be seriously damaged in the event of
an accident or impact involving the vehicle
underbody.
Stop as soon as it is safe to do so and switch
off the ignition.
Contact a PEUGEOT dealer or a qualified
workshop without delay.
In the event of exposure to a fire
Immediately exit and evacuate all
passengers from the vehicle. Never attempt
to fight the fire yourself - risk of electrocution!
You must immediately contact the emergency
services, informing them that the incident
involves a hybrid vehicle.

Practical information
For your safety and driving comfort, it is
important to have them regularly checked by a
PEUGEOT dealer or a qualified workshop.
Timing and accessory kits
Timing and accessory kits are used from
the time the engine is started until it is
switched off. It is normal for them to wear over
time.
A
faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)

To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, PEUGEOT
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel Particle Filter
(DPF) for the treatment of exhaust gases.
SCR System
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue® is contained in a special
tank holding about 17 litres.
Its capacity allows a driving range of
approximately 5,600
miles (9,000 km), which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
further 1,500 miles (2,400
km) before the tank is
empty and the vehicle blocked.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a
system required by legislation prevents
starting of the engine.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard: the vehicle becomes
polluting.
In the event of a confirmed SCR system
malfunction, it is essential to visit a
PEUGEOT dealer or a qualified workshop.
After 680 miles (1,100 km), a device is
automatically activated to prevent the engine
from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue
® tank, allowing you to continue driving
in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
In order to ensure that the SCR system
operates correctly:
–

Use
only AdBlue
® fluid that meets the ISO
22241 standard.
–

Never

transfer AdBlue
® to another
container: it would lose its purity.
–

Never

dilute AdBlue
® with water.
AdBlue
® can be obtained from a PEUGEOT
dealer or a qualified workshop.
You can also visit a service station equipped with AdBlue® pumps specially
designed for passenger vehicles.
Storage recommendations
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out in the ambient air.
Never store AdBlue® containers in your
vehicle.
Precautions for use
AdBlue® is a urea-based solution. This fluid is
non-flammable, colourless and odourless (when
kept in a cool place).
In the event of contact with the skin, wash the
affected area with soap and running water. In the
event of contact with the eyes, immediately rinse
the eyes with large amounts of water or with an
eye wash solution for at least 15 minutes. Seek
medical attention if you feel a persistent burning
sensation or irritation.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high temperature, for
example), the risk of release of ammonia cannot
be excluded: do not inhale the fluid. Ammonia
