Deactivation / Reactivation  
Correct operation of these systems depends  
on compliance with the manufacturer's  
recommendations relating to the wheels (tyres  
and rims), braking and electronic components,  
as well as the assembly and repair procedures  
used by dealers.  
The use of snow tyres is recommended, to  
ensure that these systems remain effective  
in winter conditions. All four wheels must be  
fitted with tyres approved for the vehicle.  
►ꢀ Press the DRIVE MODE button to choose one of  
the three driving modes; the different modes are  
displayed in the instrument panel.  
►ꢀ Depending on the circumstances, select  
"Snow", "Mud" or "Sand".  
The chosen mode continues to be displayed in the  
instrument panel.  
►ꢀ To deactivate, select "Normal" mode or any  
other driving mode.  
The system is automatically deactivated when  
the ignition is switched off.  
In exceptional conditions (starting a vehicle stuck  
in mud, immobilised in snow, on soft ground, etc.),  
it may be useful to deactivate the ASR system to  
freely spin the wheels and regain traction.  
Reactivate the system as soon as the level of grip  
permits.  
It is set via the Driving / Vehicle touch  
screen menu.  
Deactivation is confirmed by the  
illumination of this indicator lamp in the  
instrument panel and the display of a message.  
The ASR system is reactivated automatically  
every time the ignition is switched back on or  
from 31 mph (50 km/h).  
Operating modes  
Snow  
Advanced Traction Control  
This special patented traction control system  
improves grip on snow, mud and sand.  
This mode adapts its strategy to the conditions of  
grip encountered for each of the two front wheels  
on moving off.  
Reactivation is manual below 31 mph (50 km/h).  
For optimum grip on snow, it is  
recommended to fit the vehicle with  
winter tyres.  
Malfunction  
(mode active up to 50 mph (80 km/h))  
In the event of a system malfunction, this  
warning lamp comes on, accompanied by  
an onscreen message and audible signal.  
Contact a dealer or a qualified workshop to have  
the systems checked.  
Mud  
This mode, when moving off, allows considerable  
spin on the wheel with the least grip to optimise  
clearing of the mud and to regain grip. At the  
same time, the wheel with the most grip is  
controlled in such a way as to transmit as much  
torque as possible.  
When moving, the system optimises wheel spin  
to respond to the driver's requirements as fully as  
possible.  
Activation/Deactivation  
ASR / DSC  
These systems enhance safety during  
normal driving, but should not encourage the  
driver to take extra risks or drive at high speed.  
It is in conditions of reduced grip (rain, snow,  
ice) that the risk of loss of grip increases. It  
is therefore important for your safety to keep  
these systems activated in all conditions, and  
particularly in difficult conditions.

Safety  
Sand  
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.  
Front seat belts  
This mode allows little spin on the two driving  
The front seat belts are fitted with a pyrotechnic  
pretensioning system and a force limiting system.  
wheels at the same time to allow the vehicle to  
move forward and limit the risks of getting stuck  
in the sand.  
Rear seat belts  
(mode active up to 75 mph (120 km/h))  
Do not use the other modes on sand as  
the vehicle may become stuck.  
Recommendations  
The vehicle is designed principally to  
drive on tarmac roads, but it allows you to  
occasionally drive on other less passable  
terrain.  
The pyrotechnic pretensioning seat belts are  
enabled when the ignition is on.  
Force limiter  
However, it does not permit off-road driving  
such as:  
– driving on terrain which could damage the  
underbody or strip away components (fuel  
pipe, fuel cooler, etc.) due to obstacles or  
stones in particular,  
– driving on terrain with steep gradients and  
poor grip,  
– crossing a waterway.  
This system reduces the pressure of the seat belt  
on the chest of the occupant, thus improving their  
protection.  
Each of the rear seats has a three-point seat belt  
with inertia reel.  
The outer seats are fitted with a pyrotechnic  
pretensioning and force limiting system.  
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.  
Fastening  
►ꢀ Pull the strap, then insert the tongue in the  
buckle.  
►ꢀ Check that the seat belt is fastened correctly  
by pulling the strap.  
Seat belts  
Inertia reel  
The seat belts are equipped with an inertia reel  
which allows the strap length to automatically  
adjust to your shape. The seat belt returns to its  
storage automatically when it is not used.  
Unlocking  
►ꢀ Press the red button on the buckle.  
►ꢀ Guide the seat belt as it is reeled in.
