Malfunction
In the event of a system fault when
engaging reverse gear, this warning
lamp is displayed in the instrument
panel and/or a message appears
in the screen, accompanied by an
audible signal (short beep).
Contact the dealer network or a
qualified workshop to have the
system checked.
In bad or wintry weather, ensure that the
sensors are not covered with mud, ice or
snow. When reverse gear is engaged, an
audible signal (long beep) indicates that
the sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking sensor
system.
Reversing camera
This system is a driving aid that does not
replace the need for vigilance on the part
of the driver, who must remain in control of
the vehicle at all times. The green lines represent distances of about
1
and 2 metres beyond the edge of your
vehicle's rear bumper.
The red line represent a distance of about
30 cm beyond the edge of your vehicle's rear
b u m p e r.
The lines displayed in the screen do not
allow the position of the vehicle to be
determined relative to tall obstacles (for
example: vehicles nearby).
Some deformation of the image is normal.
High pressure jet wash
When washing your vehicle, keep the
end of the high pressure lance at least
12 inches (30 cm) away from the camera
lens.
Clean the camera lens regularly using a
soft cloth.
The reversing camera function may be
supplemented with parking sensors.
The reversing camera is activated automatically
when reverse gear is engaged.
The colour visual feedback is done on the
touch screen. The blue lines represent the general direction
of the vehicle.
The blue cur ved lines represent the maximum
turning circle.

Tyre under-inflation
d
etection
The tyre under-inflation detection system
is an aid to driving which does not replace
the need for vigilance on the part of the
driver. This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
Tyre pressure should be checked when
the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than
6 miles (10 km) at moderate speeds).
Other wise, add 0.3 bar to the values
indicated on the label.
For more information on Identification
markings , including the tyre pressure
label, refer to the corresponding section.
Under-inflation alert
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. This warning is indicated by
continuous illumination of the lamp,
an audible signal and, depending on
the equipment installed, a message
displayed on the screen.
In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.
F

R
educe speed immediately, avoid excessive
steering movements and sudden braking.
F

S
top as soon as it is safe to do so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.

F If you have a compressor (such as the one in the temporary puncture repair kit) check
the pressures of the four tyres when cold.
If it is not possible to carry out this check
straight away, drive carefully at reduced
speed.
or
F

I
n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
The alert is maintained until the tyre or
tyres concerned is reinflated, repaired or
replaced.
The spare wheel (space-saver type or a
steel rim) does not have a sensor.
Operating fault
The flashing and then fixed
illumination of the under-inflation
warning lamp accompanied by the
illumination of the Ser vice warning
lamp indicates a fault with the
system.
In this case, the pressure in the tyres is no
longer monitored. This alert is also displayed when one or
more wheels is not fitted with a sensor
(for example, a space-saver or steel spare
wheel).
Go to a member of the dealer network
or a qualified workshop
to have the
system checked or, following the repair
of a puncture, to have the original wheel,
equipped with a sensor, refitted.
Any tyre repair or replacement on a wheel
fitted with this system must be carried
out by the dealer network or a qualified
workshop.
If after changing a tyre, a wheel is not
detected by your vehicle (fitting snow tyres
for example), you must have the system
reinitialised in the dealer network or by a
qualified workshop.

Fuel
Tank capacity: approximately 60 litres.
Low fuel level
When the low fuel level is reached
in the tank, this warning lamp
comes on in the instrument panel,
accompanied by an audible warning
and the display of an alert message.
When it first comes on, about
6 litres of fuel is left in the tank.
Until sufficient fuel has been added, every time
the ignition is switched on, this warning lamp
appears, accompanied by an audible signal
and an alert message. When driving, this
audible signal and alert message are repeated
with increasing frequency, as the level drops
towards 0 .
You must refuel as soon as possible to avoid
running out of fuel.
If you run out of fuel (Diesel), refer to the
corresponding section.
Refuelling
Additions of fuel must be of at least 5 litres, in
order to be registered by the fuel gauge. With Stop & Start, never refuel with the
system in STOP mode; you must switch
off the ignition with the key, or the START/
STOP button if your vehicle has Keyless
Entry and Starting.
Opening the filler cap may create a noise
caused by an inrush of air. This vacuum is
entirely normal, resulting from the sealing of the
fuel system.

Your 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 introduced.

Air filter and passenger compartment filter
Refer to the manufacturer’s
ser vice schedule for details of the
replacement intervals for these
components.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace them twice as often if
necessary .
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
Oil filter
Change the oil filter each time the
engine oil is changed.
Refer to the manufacturer’s
ser vice schedule for details of
the replacement inter val for this
component.
Particle filter (Diesel)
Depending on the version of the instrument
panel you have, the start of saturation of the
particle filter is indicated by:
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).

emporary illumination of
the Ser vice warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of the
particle filter. On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at the
exhaust on acceleration. This does not
affect the behaviour of the vehicle or the
environment.
Traffic conditions permitting, regenerate
the filter by driving at a speed of at least
37 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.

During each scheduled ser vice of your vehicle
in the dealer network or a qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system.
If the estimated distance travelled between two
ser vices is greater than around 12,500 miles
(20,000

km), it will be necessary to top up the
AdBlue
®. Once the AdBlue
® tank is empty, a system
r
equired by regulations prevents starting
of the engine.
If the SCR

system is defective, the level of
emissions from your vehicle will no longer
meet the Euro 6 standard: your vehicle
becomes polluting.
In the event of a confirmed fault with the
SCR system, you must go to the dealer
network or a qualified workshop as soon
as possible: after a running distance of
685 miles (1,100 km), a system will be
triggered automatically to prevent engine
starting.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
For more information on the Warning
lamps and the associated alerts, refer to
the corresponding section.
The AdBlue® is contained in a special tank
with a capacity of around 17 litres: its capacity
offers a driving range of around 12,500 miles
(20,000 km) before triggering an alert system
that warns you when you can drive for a further
1,500 miles (2,400 km).
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.
Topping up with AdBlue®
Filling the AdBlue® tank is an operation
included in every routine ser vice on your
vehicle by the dealer network or a qualified
workshop.
Nevertheless, given the capacity of the tank,
it may be necessary to top up the AdBlue
®
between ser vices, more particularly if an alert
(warning lamps and a message) signals the
requirement.
You can go to a member of the dealer network
or a qualified workshop.
If you envisage topping up yourself, please
read the following recommendations and
warnings carefully.
Precautions for use
AdBlue® is a urea-based solution. This fluid
is non-flammable, colourless and odourless
(stored 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. If a burning sensation or irritation
persists, get medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.

Temporary puncture
repair kit
This kit comprises a compressor and a sealant
cartridge.
It allows the temporary repair of a tyre.
You are then able to go to the nearest garage.
It is designed to repair most punctures
which could affect the tyre, located on the
tyre tread or shoulder.
Its compressor can be used to check and
adjust the pressure of the tyre.
Tyre under-inflation detection
If the vehicle is fitted with tyre under-
inflation detection, the under-inflation
warning lamp will remain on after the
wheel has been repaired until the system
is reinitialised by a dealer or a qualified
workshop.
The vehicle's electric system allows the
connection of the compressor for long
enough to inflate a tyre after a puncture
repair. Only
the 12 V socket at the front of
the vehicle allows the compressor to be
connected for long enough to repair or
inflate the vehicle tyre.
The other 12 V sockets of the vehicle
are not designed to be used with the
compressor.
