Electronic stability programme (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
These systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards improved control in
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by a
reduction in the resistance of the pedal and an
increase in the effectiveness of the braking.
Anti-slip regulation (ASR)
This system (also known as Traction Control)
optimises traction in order to avoid 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, this system 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.

Trailer stability assist (TSA)
This system allows control of the vehicle to be
retained when towing a trailer, so as to avoid
the risk of snaking.
It is available on vehicles with factory-fitted
trailer wiring (preparation for towbar option
or the towbar with quickly-detachable towball
pack).

Anti-lock braking system (ABS) and electronic brake force
distribution (EBFD)
The fixed illumination of this warning
lamp signals that there is a fault with
the ABS.
Illumination of this warning lamp, coupled
with the STOP and ABS warning
lamps, accompanied by the display of a
message and an audible signal, signals
that there is a fault with the electronic
brake force distribution (EBFD).
You must stop as soon as it is safe to do so.
Call a PEUGEOT dealer or a qualified
workshop. When changing wheels (tyres and
rims), ensure that these are approved
for your vehicle. In emergency braking, press ver y
firmly and maintain this pressure. Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
Intelligent traction control
system
Depending on version, your vehicle has a
system to help driving on snow: intelligent
traction control.
This system detects situations of difficult
sur face grip 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 spin to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of adhesion.
The vehicle retains conventional braking. Drive
carefully at moderate speed.
Contact a PEUGEOT dealer or a qualified
workshop as soon as possible.

Anti-slip regulation (ASR) / Dynamic stability control (DSC)
Operation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of a
problem of grip or trajectory.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate the
ASR system, so that the wheels can turn freely
and regain grip.
Reactivate the system as soon as the level of
grip permits.Deactivation is done in the Driving
menu of the touch screen.
Reactivation
The ASR system is reactivated automatically
every time the ignition is switched back on or
from 30 mph (50 km/h).
Below 30 mph (50 km/h), you can reactivate it
manually:
Operating fault
This is indicated by flashing of this
warning lamp in the instrument panel.
Illumination of this warning lamp,
accompanied by the display of a
message and an audible signal,
indicates a fault with the system.
Contact a PEUGEOT dealer or a qualified
workshop to have the systems checked.
It is confirmed by the display of a message.
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.
ASR / DSC
These systems offer increased safety
in normal driving, but they should not
encourage the driver to take extra risks
or drive at high speed.
It is in conditions of reduced grip
(rain, snow, black 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.
The correct operation of these
systems depends on observation of
the manufacturer's recommendations
regarding as much the wheels (tyres
and rims), braking and electronic
components as the assembly and repair
procedures used by PEUGEOT dealers.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain
neutral behaviour on the road.
After an impact, have these systems
checked by a PEUGEOT dealer or a
qualified workshop. Reactivation is done in the Driving

menu of the touch screen.
It is confirmed by the display of a
message.

Trailer stability assist
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability programme (ESC) must
not have any faults.
Between 36 and 100 mph (60 and 160 km/h), if
the system detect oscillations (snaking) in the
movement of the trailer, it acts on the brakes to
stabilise the trailer and, if necessary, reduces
engine power to slow down the vehicle.
For information on the weights and towed
loads, refer to the "Technical data" section or
the registration certificate for your vehicle.
For advice on driving safely when To w i n g
a trailer , refer to the corresponding section.
When towing, this system reduces the risk of the vehicle or trailer snaking.
It is available on vehicles with factory-fitted trailer wiring (preparation for towbar option or the towbar with quickly-detachable towball pack).
The correction is signalled by the
flashing of this indicator lamp in the
instrument panel and illumination of
the brake lamps.
Operating fault
Should a fault occur with the system,
this warning lamp comes on in the
instrument panel, accompanied by
the display of a message and an
audible signal.
If you continue to tow a trailer, reduce your
speed and drive carefully!
Contact a PEUGEOT dealer or a qualified
workshop
to have the system checked. The trailer stability assist system offers
increased safety in normal driving,
provided that the recommendations on
towing a trailer are observed. It should
not encourage the driver to take risks,
such as towing a trailer in adverse
operating conditions (overloading,
failure to observe the trailer nose
weight, worn or under-inflated tyres,
faulty braking system, ….)
or drive at
too high a speed.
In certain certain cases, oscillation of
the trailer may not be detected by the
ESC system, particularly with a light
t r a i l e r.
When driving on slippery or poor
sur faces, the system may not be able to
prevent sudden snaking of the trailer.

Special patented traction control system which
improves traction on snow, mud and sand.
This system, the operation of which has been
optimised for each situation, allows you to
manoeuvre in most conditions of poor grip
(encountered during touring use).This mode is calibrated for a low level of wheel
spin, based on the different levels of grip
normally encountered on the road.This mode adapts its strategy to the conditions
of grip encountered for each of the two front
wheels on moving off.

The accelerator pedal should be pressed
sufficiently to allow the system to use the power
of the engine. Operation at high engine speeds
is completely normal.
Every time the ignition is switched off,
the system automatically resets to this
mode.
A five-position selector knob allows you to
choose the setting best suited to the driving
conditions encountered.
An indicator lamp associated with each mode
comes on, accompanied by the display of a

All terrain (mud, damp grass, ...)
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.
(mode active up to 50 mph (80 km/h))F

P
lace the knob in this position.
Sand
This mode allows little spin on the two driving
wheels at the same time to allow the vehicle to
move for ward and limit the risks of getting stuck
in the sand.

P
lace the knob in this position. You can deactivate certain
ESC systems (ASR and DSC)
by turning the knob to the

Driving advice
Your vehicle is designed principally to
drive on tarmac roads but it allows you
to drive on other less passable terrain
occasionally.
However, it does not permit off-road
driving such as:
-

c
rossing and driving on terrain
which could damage the underbody
or strip away components (fuel
pipe, fuel cooler...) due to obstacles
or stones in particular,
-

d
riving on terrain with steep
gradients and poor grip,
-

c
rossing a stream.
Do not use the other modes on sand as
the vehicle may become stuck. These systems are reactivated
automatically from 30 mph (50 km/h) or
every time the ignition is switched on.

Hill Assist Descent Control
System that provides assistance when
descending on loose or soft sur faces (gravel,
mud...) or a steep gradient.
This system reduces the risk of slip or loss
of control of the vehicle when descending,
whether going forward or in reverse.
During a descent, it assists the driver in
maintaining a constant speed, depending
on the gear engaged, while progressively
releasing the brakes.Operation
By default, the system is not selected.
The state of the system does not stay in
memory when the ignition is switched off.
The driver can select the system with the
engine running and the vehicle stationary or at
speeds of up to about 30 mph (50 km/h).F
O nce the vehicle starts its descent, you
can release the accelerator and brake
pedals, speed is regulated by the system:
-
