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.
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 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 braking efficiency.
Anti-slip regulation (ASR)
This system 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.The vehicle retains conventional braking. Drive
carefully at moderate speed.
Contact a PEUGEOT dealer or a qualified
workshop as soon as possible.
Illumination of this warning lamp,
linked 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 on a PEUGEOT dealer or a qualified
workshop.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
When braking in an emergency, press
very firmly and maintain this pressure. When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems
checked by a PEUGEOT dealer or a
qualified workshop.
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 with grip or trajectory.
This is indicated by flashing of this
warning lamp in the instrument panel.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
Reactivate the system when grip conditions
allow.

Safety

102
Deactivation is done via the Driving/
Vehicle menu of the touch screen.
It is confirmed by the illumination of
this warning lamp in the instrument
panel and the display of a message.
Reactivation
The ASR system is reactivated automatically
every time the ignition is switched back on or
from 31 mph (50 km/h).
Below 31 mph (50
km/h), you can reactivate it
manually:
Activation is done via the Driving/
Vehicle menu of the touch screen.
It is confirmed by this warning lamp
in the instrument panel going out and
the display of a message.
Malfunction
Illumination of this warning lamp,
accompanied by the display of a
message and an audible signal,
indicates a fault with the system. 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, 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 obser vation 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.
The use of snow tyres is recommended,
in order to be able to benefit from the
efficiency of these systems in winter
conditions.
In this case, it is essential to equip the
four wheels with tyres approved for your
vehicle.
Contact a PEUGEOT dealer or a qualified
workshop to have the systems checked.
Trailer stability assist (TSA)
When towing, this system reduces the risk of
the vehicle or trailer swaying.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control (ESC) must not
have any faults.
If the system detects oscillations (snaking) in
the movement of the trailer at speeds between
37 and 99 mph (60 and 160 km/h), it acts
on the brakes to stabilise the trailer and, if
necessary, reduces the engine power to slow
down the vehicle. The correction is signalled by the
flashing of this warning lamp in the
instrument panel and illumination of
the brake lamps.
For information on the weights and towed
loads, refer to the "Technical data" section or
the registration certificate for your vehicle.
To ensure complete safety while driving with
a Towing device , refer to the corresponding
section.

In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.
New vehicle
Do not pull a trailer before having driven at least
approximately 620 miles (1,000 kilometres).
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
adjustment , refer to the corresponding
section.
Certain driving or manoeuvring aid
functions are automatically disabled
if
an approved towbar is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
A few seconds after switching off the ignition,
this system locks the engine control system,
therefore preventing the engine from being
started in the event of a break-in.
If the system fails, as reported by a message,
the engine will not start.
Contact the PEUGEOT dealer.
