– Jolting and knocking noise during hill starts.
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 heating up.
In all cases, pay 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
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use of
engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine immobiliser
system, with a code that must be recognised in
order for starting to be 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.
For versions equipped with Proximity Keyless
Entry and Start, the electronic key is also
detected in the boot.
If it is not detected, a message is displayed.
Move the electronic key so that the engine can
be started or switched off.
If there is still a problem, refer to the "Key not
detected - Back-up starting or Back-up switch-
off" section.

Practical information07
Accelerated charging
The end of charging is indicated by the charging
control unit and by the fixed lighting of the green
indicator lamp in the flap.
►  Hang up the nozzle on the charging unit and
close the charging flap.
Fast charging
The end of charging is indicated by the charger
and by the fixed lighting of the green indicator
lamp in the flap.
►  Hang up the nozzle on the charging station.
►  Depending on version, replace the protective
cover on the base and close the charging flap.
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 load which
can be towed must be reduced by 10% per
1,000 metres of altitude.
Use towing devices and their genuine
wiring harnesses approved by the
Manufacturer. It is recommended that the
fitting be performed by a dealer or a qualified
workshop.
If not fitted by a dealer, it must still be fitted
in accordance with the Manufacturer's
instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated if an approved
towing system is used.
Observe the maximum authorised towable
weight, indicated on the vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data section of
this guide.
Complying with the maximum authorised
nose weight (towball) also includes the use of
accessories (bicycle carriers, tow boxes, etc.).
Observe the legislation in force in the
country where you are driving.
Electric motor
Electric vehicles must never be equipped
with towing devices.
It is therefore not possible to tow a trailer or
caravan.
Roof bars
As a safety measure and to avoid
damaging the roof, it is essential to use
the transverse bars approved for the vehicle.
Observe the instructions on fitting and use
contained in the guide supplied with the roof
bars.


To install the roof bars, you must secure them
only to the four fixing points on the roof frame.
These points are concealed by the vehicle's doors
when they are closed.
The roof bar fixings include a lug to be fitted into
the hole at each fixing point.
Maximum load distributed over the roof
bars, for a loading height not exceeding
40 cm: 75 kg.
As this value may change, please verify the
maximum load set out in the manual supplied
with the roof bars.

138
Practical information07
If the height exceeds 40 cm, adapt the speed
of the vehicle to the profile of the road to avoid
damaging the roof bars and the fixings on the
vehicle.
Be sure to refer to national legislation in order
to comply with the regulations for transporting
objects which are longer than the vehicle.
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.
Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the vehicle
when braking.
The snow chains must be fitted only to
the front wheels. They must never be
fitted to "space-saver" type spare wheels.
Take account of the legislation specific to
each country on the use of snow chains
and the maximum authorised speed.
Use only chains designed to be fitted to the type
of wheel fitted to the vehicle:
Original tyre size Chain type 215/65 R16 Cannot be fitted with chains
215/60 R17 Polaire XP9 with manual locking
215/55R18 Cannot be fitted with chains
For more information on snow chains, contact a
dealer or a qualified workshop.
Installation tips
►  To fit the chains during a journey, stop the
vehicle on a flat surface on 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 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 before
you leave, you practise fitting the snow
chains on a level and dry surface.
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.
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, you can still
use functions such as the audio and telematic
system, the wipers and the dipped beam
headlamps or courtesy lamps, for a combined
duration of approximately 40 minutes.
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 less than 10 minutes, to use the equipment
for approximately 5 minutes.
– For more than 10 minutes, 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.
