► Do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, contact
a dealer or a qualified workshop.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
►  Distribute the load in the trailer so that the
heaviest items are as close as possible to the axle
and the nose weight (at the point where it joins
your vehicle) approaches the maximum permitted
without exceeding it.
Tyres
►  Check the tyre pressures of the towing vehicle
and of the trailer, observing the recommended
pressures.
Lighting
►  Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine towing device is used, the
rear parking sensors will be deactivated
automatically to avoid the audible signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►  Reduce speed and lower the engine speed to
limit the amount of heating produced.
►  Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a dealer.
Starting/switching off the
engine
The electronic key must be present in the
passenger compartment.
If the electronic key is not detected, a message
is displayed.

Electrical system
The electrical circuit of the rechargeable hybrid
system is identified by orange cables and its
components are marked with this symbol:


The rechargeable hybrid powertrain uses
a voltage of between 240 V and 400 V.
This system may be hot both when the ignition
is on and after switching it off.
Comply with the warning messages shown on
the labels, particularly inside the charging flap.
High voltage system voltage is dangerous
and can cause burns or other injuries or
even fatal electric shock.
Since damage to high voltage components is
not visible, the Manufacturer recommends
that you:
–

Ne
ver touch the components, damaged
or not, and never let your jewelry or other
metallic objects come into contact with these
components.
–

Ne
ver work on the orange high voltage
cables or on any other high voltage component
marked with the Electric risk label. Any
intervention on the high voltage system
must be carried out by qualified persons in

ver damage, modify or remove the orange
high voltage cables or disconnect them from
the high voltage network.
–

Ne
ver open, modify or remove the cover of
the traction battery.
–

Ne
ver work with cutting and forming tools
or heat sources near high voltage components
and cables.
In case of low level of fluid in the cooling
tank, the refilling shall only be performed in a
qualified and trained workshop to verify that
the leakage is not in the traction battery.
Any intervention on the high voltage system
must be carried out by qualified persons in
workshops qualified and approved to carry out
this type of work.Damage to the vehicle or the traction battery
could result in the leakage of toxic gases
or fluids either immediately or later. The
Manufacturer recommends that you:

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
of the front grille and a second element for the
lower part.
In case of difficulty with installation/
removal
Contact a dealer or a qualified workshop.
Before any operation, ensure that the
engine is off and the cooling fan has
stopped.
It is essential to remove them when:
– the outside t emperature exceeds 10°C.
–

rec
overy is in progress.
–

the speed is abo
ve 75 mph (120 km/h).
Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the vehicle
when braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Observe the legislation in force in your
country relating to the use of snow chains
and maximum authorised speeds.
Only use chains that have been designed to be
fitted to the type of wheel on the vehicle:

Practical information07
For more information, contact a dealer or a
qualified workshop.
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
This system manages the duration of use of
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.
–

For more than 10 minut
es, to use the equipment
for approximately 30 minutes.
Let the engine run for the specified duration to
ensure that the battery charge is sufficient.
To recharge the battery, avoid repeatedly or
continuously restarting the engine.
A flat battery prevents the engine from
starting.
For more information on the 12 V battery, refer
to the corresponding section.
Load reduction mode
This system 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 the air conditioning
and the heated rear screen.
The deactivated functions are reactivated
automatically as soon as conditions permit.

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.

162
Practical information07
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
► Grasp the dipstick by its coloured grip and pull
it out completely.
►  Wipe the end of the dipstick using a clean, lint-
free cloth.


►  Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil level:
the correct level is between marks A (max) and
B (min).
Do not start the engine if the level is:
–

abo
ve mark A: contact a dealer or a qualified
workshop.
–

belo
w mark B: top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for your engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your dealer or qualified
workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►  Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►  Wait a few minutes before checking the level
again using the dipstick.
►  Top up the level if necessary.
►  After checking the level, carefully screw the
oil filler cap back on and replace the dipstick in
its tube.
The oil level indication displayed on the
instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to the
"MAX" mark. If not, check the brake pads
for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine 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
