Safety05
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.

Driving06
Parking the vehicle with the brake
released
In very cold conditions (ice), applying the
parking brake is not recommended.
To immobilise the vehicle, place the chock
against one of the wheels.
Mode P is automatically selected when
the ignition is switched off. The wheels
are blocked.
For more information on Free-wheeling, refer
to the corresponding section.
If you open the driver's door while mode N
is engaged, an audible signal will sound
and mode P will be engaged. The audible signal
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.
Automatic gearbox
Automatic 8-speed gearbox with a push selector.
It also offers a manual mode with gear changes
via control paddles located behind the steering
wheel.
Gearbox selector positions
P. Park
For parking the vehicle: the front wheels are
blocked.
R. Reverse gear
N. Neutral
For moving the vehicle with the ignition off, or
to allow it to free-wheel.
For more information on Changing to free-
wheeling, refer to the corresponding section.
D. Driving in automatic mode
The gearbox manages gear changes according
to the style of driving, the road profile and the
vehicle load.
M. Driving in manual mode
The driver changes gear using the steering-
mounted controls.
