Driving
6It takes into account the last values stored 
during the reinitialisation request. It is therefore 
essential that the tyre pressure is correct during 
the operation. This operation is the driver’s 
responsibility.
The tyre under-inflation detection cannot, in any circumstances, replace the need 
for vigilance on the part of the driver.
This system does not avoid the need to 
regularly check the tyre pressures (including 
the spare wheel), especially before a long 
journey.
Driving with under-inflated tyres, particularly 
in adverse conditions (heavy load, high 
speed, long journey):
–
 
worsens road-holding.
–
 
lengthens braking distances.
–
 
causes premature wear of the tyres.
–
 
increases energy consumption.
The inflation pressures defined for the  vehicle can be found on the tyre pressure 
label.
For more information on the  Identification 
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly 
when the tyres are "cold" (vehicle stopped for 
1
 
hour or after a journey of less than 6 miles 
(10
 
km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures 
shown on the label.
Snow chains
The system does not have to be 
reinitialised after fitting or removing snow 
chains.
Under-inflation alert
This is signalled by the fixed illumination  of this warning lamp, accompanied by an 
audible signal and, depending on equipment, the 
display of a message.
►
 
Reduce speed immediately
 , avoid excessive 
steering movements and avoid sudden braking.
►
 
Stop the vehicle as soon as it is safe to do 
so.
The loss of pressure detected may not  always cause visible deformation of the 
tyre.
Do not rely on just a visual check.
►
 
Using a compressor
 , such as the one in 
the temporary puncture repair kit, check the 
pressures of all four tyres when cold.
►
 
If it is not possible to carry out this check 
immediately
, drive carefully at reduced speed.
►
 
In the event of a puncture, use the 
temporary puncture repair kit or the spare wheel 
(depending on equipment).
Driving too slowly may not ensure 
optimum monitoring.
The alert is not immediately triggered in the 
event of a sudden loss of pressure or tyre 
blow-out. This is because analysis of the 
values read by the wheel's speed sensors 
can take several minutes.
The alert may be delayed at speeds below 
25
 
mph (40   km/h), or when adopting a sporty 
driving mode.
The alert is kept active until the system is  reinitialised.
Reinitialisation
► The system must be reinitialised after any 
adjustment to the pressure of one or more tyres, 
and after changing one or more wheels.
Before reinitialising the system, make 
sure that the pressures of the four tyres 
are correct for the conditions of use of the 
vehicle and conform to the values written on 
the tyre pressure label.
Check the pressures of the four tyres before 
performing the reinitialisation.
The system does not advise if a pressure is 
incorrect at the time of reinitialisation.
With the vehicle stationary, the system 
can be   reinitialised   in the 
Settings>Vehicle touch screen application.
