All tyre specifications are listed on the
tyre/paint label. For more information
on Identification markings, refer to the
corresponding section.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer snaking.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control system (ESC) must
not have any faults.
The vehicle speed must be between 37 and 99
mph (60 and 160 km/h).
If the system detects that the trailer is
snaking, it applies the brakes to stabilise
the trailer and reduces engine power, if necessary,
to slow the vehicle (indicated by the flashing of
this warning lamp on the instrument panel and
the brake lamps coming on).
For information on weights and towed loads, refer
to the Engine technical data and towed loads
section or your vehicle’s registration certificate.
To ensure safe driving with a Towing device, refer
to the corresponding section.
Malfunction
If a fault occurs, this warning lamp lights
up on the instrument panel, accompanied
by a message and an audible signal.
To continue towing a trailer, reduce speed and
drive carefully!
Have it checked by a dealer or a qualified
workshop.
The trailer stability control system
provides an extra safety feature under
normal driving conditions, when following the
recommendations for use of trailers and
current legislation in force in your country. It
must not encourage the driver to take extra
risks, such as using a trailer in unsuitable
conditions of operation (e.g. excessive load,
exceeded nose weight, worn or under-inflated
tyres, faulty braking system) or driving at
excessive speed.
In certain cases, the system may not detect
trailer snaking, particularly with a light trailer.
When driving on slippery or poor surfaces, the
system may not be able to prevent sudden
trailer snaking.
Seat belts
Inertia reel
The seat belts are equipped with an inertia
reel which allows the strap length to adjust
automatically to the shape of the user. The seat
belt returns to its storage automatically when it
is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiting system
This system reduces the pressure of the seat belt
on the chest of the occupant, thus improving their
protection.
In the event of an impact
Depending on the nature and seriousness
of the impacts, the pyrotechnic device may
trigger before and independently of airbag
deployment. Deployment of the pretensioners
is accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt system
checked, and if necessary replaced, by a dealer
or a qualified workshop.

► 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.

100Driving06
The indicator lamp goes out to confirm the release
of the parking brake, accompanied by the display
of the message "Parking brake released".
The indicator lamp flashes in response to a
manual request to apply or release the brake.
In the event of a battery failure, the
electric parking brake will not operate.
As a safety measure, if the parking brake is not
applied, immobilise the vehicle by placing the
supplied chock against one of the wheels.
Contact a dealer or a qualified workshop.


Before leaving the vehicle, check that the
parking brake is applied: the parking
brake indicator lamps on the instrument panel
and the control must be on fixed.
If the parking brake is not applied, there is an
audible signal and a message is displayed on
opening the driver's door.
Never leave a child alone inside the
vehicle, as they could release the parking
brake.
When the vehicle is parked: on a steep
slope, heavily loaded or during towing
Turn the wheels toward the pavement and
select mode P on the automatic gearbox.
When towing, the vehicle is approved for
parking on slopes of up to 12%.

stops when the driver's door is closed.
Deactivating automatic
operation
In some situations, for example when it is
extremely cold or when towing (e.g. caravan,
breakdown), it may be necessary to deactivate
automatic operation of the system.
►  Start the engine.
►  Use the control to apply the parking brake, if it
is released.
►  Take your foot fully off the brake pedal.
►  Keep the control pushed in the release
direction for 10 to a maximum of 15 seconds. ► 
Release the control.
►  Depress and hold the brake pedal.
►  Pull the control in the application direction for
2 seconds.
This indicator lamp on the instrument
panel comes on to confirm deactivation of
the automatic functions.
►  Release the control and the brake pedal.
From this point onwards, only the manual
functions, using the control, allow the parking
brake to be applied and released.
►  Follow this procedure again to reactivate
automatic operation (confirmed by the indicator
lamp on the instrument panel going out).
Emergency braking
If depressing the brake pedal fails to provide
effective braking or in exceptional circumstances
(e.g. driver unwell, assisted driving), the vehicle
can be braked by sustained pulling on the electric
parking brake control. Braking continues for as
long as the control is kept pulled, and ceases
when the control is released.
The ABS and DSC systems stabilise the vehicle
during emergency braking.
If emergency braking malfunctions, the message
"Parking brake fault" will be displayed on the
instrument panel.
If the ABS and DSC systems
malfunction, indicated by lighting
one or both warning lamps on the instrument
panel, the vehicle’s stability is no longer ensured. ► 
In this case, ensure the vehicle's stability by
successive and repeated "pull-release" actions on
the electric parking brake control until the vehicle
comes to a complete stop.

Cruise control - Specific
recommendations
The cruise control function does not
guarantee compliance with the maximum
authorised speed and the safety distance
between vehicles, the driver remains
responsible for their driving.
In the interest of public safety, only use cruise
control if the traffic conditions enable vehicles
to drive at a steady speed and maintain an
adequate safety distance.
Remain vigilant while cruise control is
activated. If you press and hold one of the
speed setting modification buttons, your
vehicle may change speed very abruptly.
When descending a steep hill, the cruise
control system cannot prevent the vehicle from
exceeding the set speed. Brake if necessary to
control the vehicle speed.
On steep climbs or when towing, the set speed
may not be reached or maintained.
Exceeding the programmed speed setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
