particularly on flooded roads, refer to the
corresponding section. Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from an
automatic change to START mode.Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
This system only operates when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

w
ith the driver’s door closed.
The hill start assist function cannot be
deactivated.
Operation
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal:
-

i
f you are in first gear or neutral with a
manual gearbox, On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake

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.

Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen...
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy saving mode
System that manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can
still use functions such as the audio
equipment, windscreen wipers, dipped
beam headlamps,
courtesy lamps, etc. for a
maximum combined period of thirty minutes.
This period may be greatly reduced if the
battery is not fully charged.
Switching to this mode
Once this period has elapsed, a message
appears in the screen indicating that the
vehicle has switched to the energy saving
mode and the active functions are put on
st a n d by.If the telephone was operated via
the touch screen at that moment, the
connection would be interrupted after
10


minutes.
Exiting the mode
These functions will be automatically restored
the next time the vehicle is used.
F
I
n order to restore the use of these functions
immediately, start the engine and let it run
for a few minutes.
The time available to you will then be double
the period for which the engine is left running.
However, this period will always be between
five and thirty minutes.
The engine will not start if the battery is
discharged.

Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a level drops significantly, have the
corresponding system checked by the dealer
network or a qualified workshop.The fluid must comply with the
manufacturer's recommendations and with
the vehicle's engine.
Take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and
the cooling fan could start at any time
(even
with the ignition off).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive. Do not discard used oil or fluids into
sewers or onto the ground.
Return used oil to the dealer network or
a qualified workshop and dispose of it in
the containers reser ved for this purpose.
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles equipped with an
electric gauge, or using the dipstick.
To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine stopped for more than
30


minutes.
It is normal to top up the oil level between two
ser vices (or oil changes). We recommend that
you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
Checking using the dipstick

maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
Matt finish
If your vehicle is coated with a clear, matt
varnish, it is essential that you take the
following instructions into account to avoid
damaging the paint, due to an inappropriate
treatment. These instructions are also valid for
the alloy wheels coated in a clear, matt varnish.
Textured paint
The textured paint reacts to light with variations
of appearance and finish that emphasise the
car's lines and form. This paint coating has
particles that remain visible and create a
unique satin relief effect. Its lightly granulated
texture gives it a surprising feel.
