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.


The filler cap is built into the flap.
►  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).


►  Insert the filler nozzle and push it in as far as
possible before starting to refuel (to minimise the
risk of splashing).
►  Fill the tank.
Do not continue after the nozzle’s third cut-out.
Doing so may cause malfunctions.
►  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

When 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.

and the durability of your traction battery,
the Manufacturer recommends that you:
–

Do no
t fully charge the battery of your
electric vehicle daily (charge the traction
battery below 80% as often as possible).
–

Do no
t completely discharge the battery.
–

Do no
t store the vehicle for a long period
of non-use (more than 12 hours) when the
traction battery has a low or high charge level.
Prefer a charge level between 20 and 40%.
–

Limit the use o
f fast charging.
–

Do no
t expose the vehicle to temperatures
below -30°C and above +60°C for more than
24 hours.

traction battery is too low can lead to the
vehicle breaking down and can lead to
accidents or serious injuries. ALWAYS make
sure the traction battery has a sufficient
charge level.
Low charging / Parking
If the outside temperature is negative,
it is recommended not to park your vehicle
outside for several hours at a low charging
(less than 20%).
Vehicle in storage for more than 1 month
In the event of a long period of non-use
of the vehicle (beyond 4 weeks) without the
possibility of charging when restarting, the
self-discharge may make it impossible to
restart if the traction battery charge level is a
low or very low, especially at negative ambient
temperatures. ALWAYS make sure that the
traction battery has a charge between 20%
and 40% if you do not plan to use your vehicle
for several weeks.
Do not connect the charging cable.
Always park the vehicle in a place with
temperatures between -10°C and 30°C
(parking in a place with extreme temperatures
can damage the traction battery).
Refer to the Accessory battery (Rechargeable
hybrid) section for the battery disconnection
procedure.
Precautions
Rechargeable hybrid vehicles have
been developed in accordance with the
recommendations for maximum electromagnetic
field limits established by the ICNIRP
(International Commission on Non-Ionizing
Radiation Protection - 1998 Guidelines).
Wearers of pacemakers or equivalent
devices should consult a doctor to enquire
about any applicable precautionary measures, or
contact the manufacturer of their implanted
electronic medical device to check that it is
guaranteed to operate in an environment
compliant with the ICNIRP guidelines.

Towing device
Load distribution
►  Distribute the load in the trailer so that
the heaviest items are as close as possible to
the axle, and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing
engine performance. The maximum towable
load must be reduced by 10% per 1,000 metres of
altitude.
Use genuine towing devices and wiring
harnesses approved by the Manufacturer.
We recommend having them fitted by a dealer
or a qualified workshop.
If not fitted by a dealer, they must still be
fitted in accordance with the Manufacturer's
instructions.
Important: if the vehicle has a motorised
tailgate and Hands-Free Tailgate Access
function, and a towing device has been fitted
outside the dealer network, it is essential to
visit a dealer or a qualified workshop to have
the detection system recalibrated - risk of
malfunction of the Hands-Free Tailgate Access
function.
Certain driving or manoeuvring aid functions
are automatically deactivated while an
approved towing system is in use.
For more information about driving with a
towing device fitted to a trailer and associated
with the Trailer stability assist, refer to the
corresponding section.
Comply with the maximum authorised
towable weight, as indicated on your
vehicle's registration certificate, on the
manufacturer's label and in the Technical data
section of this guide.

Practical information07
Fitting on longitudinal bars

The transverse bars must be fixed at the markings
located on the longitudinal bars.
Direct fitting on roof

The transverse bars must only be fixed at the
four anchorage points located on the roof frame.
These points are concealed by the vehicle doors
when the doors are closed.
The roof bar fixings have a stud which must be
inserted into the opening of each anchorage
point.
Recommendations
Distribute the load uniformly, taking care
to avoid overloading one of the sides.
Arrange the heaviest part of the load as close
as possible to the roof.
Secure the load firmly.
Drive gently: the vehicle will be more
susceptible to the effects of side winds and its
stability may be affected.
Regularly check the security and tight
fastening of the roof bars, at least before each
trip.
Remove the roof bars once they are no longer
needed.
Very cold climate screens
(Depending on country of sale)
This removable device prevents the accumulation
of snow around the radiator cooling fan.
It consists of a first element for the upper part

Installation tips
►  To fit the snow chains during a journey, stop
the vehicle on a flat surface at the side of the
road.
►  Apply the parking brake and position any
wheel chocks under the wheels to prevent
movement of the vehicle.
►  Fit the snow chains following the instructions
provided by the manufacturer.
►  Move off gently and drive for a few moments,
without exceeding 31 mph (50 km/h).
►  Stop the vehicle and check that the snow
chains are correctly tightened.
It is strongly recommended that you
practise fitting the snow chains on a level
and dry surface before setting off.
Avoid driving with snow chains on roads
that have been cleared of snow to avoid
damaging the vehicle's tyres and the road
surface. If the vehicle is fitted with alloy
wheels, check that no part of the chain or its
fixings is in contact with the wheel rim.
Rechargeable hybrid vehicles
The use of snow chains is only authorised
on the front wheels.
The driving mode selector must be on the 4WD
position (depending on version).
Energy economy mode

certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.
After switching off the engine and for a maximum
cumulative period of around 30 minutes, you can
continue to use functions such as the audio and
telematics system, dipped beam headlamps or
courtesy lamps.
Selecting the mode
A confirmation message is displayed when
energy economy mode is entered, and the active
functions are placed on standby.
If a telephone call is in progress at the
time, it will be maintained for around 10
minutes via the audio system’s hands-free
system.
Exiting the mode
These functions are automatically reactivated the
next time the vehicle is used.
To restore the use of these functions immediately,
start the engine and let it run:
–

For le
ss than 10 minutes, to use the equipment
for approximately 5 minutes.
–

Diesel fuel system
This system is under very high pressure.
All work must be carried out only by a dealer or
a qualified workshop.
Checking levels
Check all of the following levels regularly in
accordance with the Manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a dealer or a
qualified workshop.
The fluids must comply with the
Manufacturer's requirements 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 and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a dealer or a qualified
workshop.
Engine oil
The level is checked, with the engine
having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped with
an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended that
you check the level, and top up if necessary, every
3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.

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

163
