Under-inflation detection
the system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed.
th

e system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres.th e under-inflation detection system
does not replace the vigilance or the
responsibility of the driver.
th

is system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous condition
(high loading, high speed, long journey).
System which automatically checks the pressures of the tyres while driving.th
e inflation pressures defined for
your vehicle can be found on the tyre
pressure label.
See the "Identification markings"
section.
ty

re pressures should be checked
when the tyres are "cold" (vehicle
stopped for 1 hour or after a journey of
less than 6 miles (10 km) at moderate
speeds).
Other wise (when hot), add 0.3 bar to
the pressures shown on the label.
Driving with under-inflated tyres
increases fuel consumption.

Under-inflation alertReinitialisation
Before reinitialising the system, ensure
that the pressures of the four tyres are
correct for the use of the vehicle and in
line with the recommendations on the
tyre pressure label.
th

e under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.
th

is is given by fixed illumination of
this warning lamp, accompanied by
an audible signal and, depending on
equipment, the display of a message.
It is necessary to reinitialise the system every
time one or more tyre pressure is adjusted, and
after changing one or more wheels.
A label attached to the middle pillar, driver's
side, gives a reminder of this.

electronic stability control (eS C)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
this system improves the stability and
manoeuvrability of your vehicle when braking
and contributes towards improved control in
corners, in particular on poor or slippery road
surfaces.
th

e ABS prevents wheel lock in the event of
emergency braking.
th

e electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered according to the speed at which
the brake pedal is pressed.
t
h
is is felt by a
reduction in the resistance of the pedal and an
increase in the effectiveness of the braking.
Anti-slip regulation (ASR)
the ASR system (also known as tr action
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.

Operation
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
In emergency braking, press
very firmly without releasing the
pressure. When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
When this warning lamp comes on,
accompanied by an audible signal
and a message, it indicates that there
is a fault with the ABS, which could
cause loss of control of the vehicle
when braking.
When this warning lamp comes on,
coupled with the STOP

Intelligent traction control
system
the use of snow tyres is strongly recommended
on sur faces offering low levels of adhesion. that there is a fault with the electronic brake
force distribution (
eB

FD), which could cause
loss of control of the vehicle when braking.
You must stop as soon as it is safe to do so.
In both cases, contact a P
e

uge
Ot
dealer or a
qualified workshop.
Depending on version, your vehicle has a
system to help driving on snow: intelligent
traction control
.
th
is system detects situations of difficult
sur face adhesion that could make it difficult to
move off or make progress on deep fresh snow
or compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
