Safety
Snow driving assistance
(Intelligent Traction Control)
Your vehicle has a system to help driving on
snow: Intelligent Traction Control.
this automatic system continuously checks
for situations of difficult surface adhesion that
could make it difficult to move off or make
progress on deep fresh snow or compacted
snow.
In these situations, Intelligent Traction
Control limits the amount of wheel slip to
provide the best traction and trajectory control.
In extremely severe conditions (deep snow,
mud...), it can be useful to temporarily
deactivate the wheel anti-slip regulation
system to allow a degree of wheel spin and so
recover grip.
It is recommended that the system be
reactivated as soon as possible.
Snow tyres are strongly recommended on
surfaces offering low levels of adhesion.

Anti-lock braking system
(ABS) and electronic brake
force distribution
(EBFD)
Operation
the fixed illumination of this warning
lamp indicates that there is a fault
with the ABS.
the vehicle retains conventional braking. Drive
carefully at moderate speed.
When this warning lamp comes on,
coupled with the STOP and ABS warning
lamps, accompanied by an audible signal
and a message, it indicates that there
is a fault with the electronic brake force
distribution (eBFD).
You must stop as soon as it is safe to do so.
In both cases, have the system checked by a
PeugeOt dealer or a qualified workshop as
soon as possible.
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.
In emergency braking, press
very firmly without releasing the
pressure.
