For triggering the pre-collision warning :
-

t
he speed is between 9 and 87 mph
(15
and 140 km/h),
-

t
he difference in speed between your
vehicle and the one in front is more than
about 9
mph (15 km/h).
•
For help in braking :
-

t
he speed is between about 19 and
50
mph (30 and 80 km/h),
-

t
he difference in speed between your
vehicle and the one in front is more than
about 19
mph (30 km/h).
•
For automatic pre-collision braking :
-

t
he speed is between about 6 and
50
mph (10 and 80 km/h),
-

t
he difference in speed between your
vehicle and the one in front is more than
about 6
mph (10 km/h)
•

t
he braking assistance systems (ABS,
EBFD, EBA) are not faulty.
•

T
he trajectory control systems (TRC, DSC)
hare not deactivated or faulty.
•

T
he vehicle is not making a sharp turn.
•

T
he system has not triggered in the last ten
seconds.
Operation
Three functional stages are possible:
• P re-collision warning : if risk of a
collision
with a
vehicle is detected, a warning lamp
comes on, accompanied by an audible
signal, to warn the driver to take avoiding
action. The triggering thresholds of the
warning can be set.
•

Br
aking assistance : increases the braking
started by the driver, but only if a
risk of
collision is detected.
•

A
utomatic pre-collision braking : if
your vehicle is approaching the vehicle
in front of you too quickly, the system
will automatically engage the brakes to
reduce the speed of impact. The collision
can be automatically avoided if the speed
difference between your vehicle and the
one in front of you is not more than 18
mph
(30


km/h).Then you are alerted by the display
of this warning indicator in the
instrument panel, accompanied by
an audible signal.
The brake lamps of your vehicle are lit to warn
other users.
The automatic braking can lead to the complete
stop of the vehicle if the situation requires. Unless the driver de-clutches quickly
enough during automatic braking,
triggering of the system may cause the
engine to stall.

Setting the thresholds for
triggering the alertDeactivation/reactivation
Press this button for more than 3 seconds.
T his warning lamp comes on in the
instrument panel and the message
"PCS OFF" is displayed. Press this button again to reactivate the
system.
This indicator lamp lights up on the
instrument panel.
The alert thresholds determine how you want
to be alerted to the risk of an imminent collision
with the vehicle travelling in front of you.
You can choose from three thresholds:
A. "Distant", to be given an early alert
(cautious driving).
B. "Normal",
C. "Close", to be given a

later alert (sporty
driving).
Press this button in succession to
scroll through the thresholds:
The default setting is "Normal". The system is reactivated automatically at
every new start using the key or the "START/
STOP " button.
Operating limits
The system only detects vehicles
(c ar s,
trucks), stationary or moving in the same
direction of traffic.
It does not detect small vehicles (bicycles,
motorcycles), pedestrians or animals, nor
non-reflective stationary objects.
This system will not trigger or inter vene if the
driver:
-

p
resses hard on the accelerator (even if the
speed limiter is active),
-

o
r suddenly turns the steering wheel
(avoidance manoeuvre).
The ability to detect is reduced if:
-

y
ou are driving in an environment with sharp
turns and/or roads in poor condition,
-

c
arrying an excessively heavy load which
badly affects the horizontal attitude of your
vehicle,
-

y
our vehicle skids.
Driving

89
When weather conditions are difficult
(extremely heavy rain, snow, fog, hail,
etc.), braking distances increase, which
may reduce the system's ability to avoid
a

collision.
The driver must therefore remain
particularly cautious.
Never let snow build up on the bonnet
or any object above the bonnet nor at
the front of the roof: this could enter the
field of vision of the sensor and obstruct
detection.
Unwanted triggering
- passing a vehicle travelling in the other
direction, at a crossroads, when your
vehicle is turning left or right,
-

i
f the vehicle in front of you kicks up water or
snow,
-

i
f your vehicle stops very close to an
overhanging wall or other vehicles,
-

w
hen your vehicle quickly draws close to
a
vehicle in front,
-

i
f the vehicle is raised or lowered,
-

i
f the vehicle is passing through a plastic
curtain,
-

i
f you are driving in fog or smoke,
-

i
f the sensor is misaligned (replacement
after a
collision).
Operating faults
Sensor fault
Operation of the laser sensor may be
disrupted by accumulation of dirt, formation
of condensation on the windscreen or
the presence of a component causing an
obstruction (e.g. an open bonnet).
If this happens, you are alerted by
the flashing of this warning lamp in
the instrument panel. Do not stick or other wise attach any object
on the windscreen in front of the sensor.
System fault
If there is a system fault, you are
a lerted by the flashing of this
warning lamp in the instrument
panel.
Have the system checked by a
PEUGEOT
dealer or a
qualified workshop.
In the event of an impact to the
windscreen at the sensor, deactivate the
system and contact a
PEUGEOT dealer
or a

qualified workshop to have your
windscreen replaced.
Do not attempt to remove, adjust or test
the sensor.
Only a
PEUGEOT dealer or a qualified
workshop is able to work on the system.
The system may detect a

risk of imminent
collision, particularly in the following conditions:
-

d

etection of an object close to the edge of
the road going into a

bend (safety rail, street
light, road sign),
-

d

etection of a

structure at the top or bottom
of a


sharp slope (advertising hoarding,
public lighting),
-

d

etection of reflective objects (central
reser vation, etc.) on the road,
-

d

etection of the top bar of a

bridge or
a


signal gantry,
-

p

assing a

vehicle travelling in the other
direction in a

corner, Use windscreen demisting and regularly clean
the area of the windscreen in front of the
sensor.

Lane departure warning
system
System that detects involuntary crossing of
longitudinal markings of roads, using a camera
that recognises the continuous or broken lines.
To increase your safety, the camera analyses
the image then triggers a
warning if the driver's
attention drops and the vehicle drifts over
a
lane marking (speed greater than 30 mph
(50


km/h)).
This system is particularly suited to motor ways
and dual carriageways.
The lane departure warning system
cannot under any circumstances replace
the need for vigilance on the part of the
driver.
You must obser ve the driving regulations
and take a
break every two hours.
When driving with snow chains or with the
spare wheel fitted, you must deactivate
the system.
Activation
Detection
You are alerted by an audible signal and the
lighting of a warning lamp in the instrument panel.
No warning is given while the direction indicator
is flashing and for approximately 20 seconds
after the direction indicator is switched off.

91
Operating fault
If there is a fault, this warning lamp
( orange) comes on in the instrument
panel.
Contact a
PEUGEOT dealer or a qualified
workshop without delay.
Detection may be disrupted:
-

I

f the road markings are worn.
-

I

f there is little contrast between the
road markings and the road surface,
-

I

f the windscreen is dirty.
-

I

n certain extreme weather conditions:
fog, heavy rain, snow, bright sunlight
or direct exposure to the sun (low sun,
leaving a
tunnel, etc.), and shadows.
Reversing camera
The reversing camera is activated automatically
when reverse gear is engaged.
The reversing camera cannot, in any circumstances,
replace the need for vigilance on the part of the driver.
The visual feedback is only shown on the
touch screen, with an indication of the edge of
the rear bumper (red line 1 ) and the general
direction of the vehicle (blue lines 2 ).It is normal to have a
part of the number plate
showing in the bottom of the screen.
Never reverse while looking only at the
screen.
High-pressure jet wash
When washing your vehicle, do not direct
the lance at the lens of the camera from
a distance of less than 30 cm.
The field covered by the camera is limited:
objects very close to the bumper or below it are
not visible.
The wide angle lens of the camera distorts
the image on the screen: the distances seen
on the screen may be different from the real
distances. This distortion varies depending on
the load conditions of the vehicle and slope of
the road. Clean the reversing camera regularly
using a soft, dry cloth.

Driving

92
Under-inflation detection
The system monitors the pressure in all four
tyres, once the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change.
The system triggers an alert as soon as it
detects a
drop in the pressure of one or more
tyres. The tyre under-inflation detection system
does not replace the need for vigilance on
the part of the driver.
This system still requires you to check the
tyre inflation pressure (including the spare
wheel) every month as well as before
a


long journey.
Driving with under-inflated tyres impairs
handling, extends braking distances and
causes early tyre wear, particularly in
adverse conditions (heavy loads, high
speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption. The tyre pressure specifications for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings
, refer to the
corresponding section.
Tyre 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.Under-inflation alert

top as soon as it is safe to do so.
This system automatically monitors the tyre
pressure while driving.
Detection of loss of pressure does not
always bring about a visible deformation
of the tyre. Do not make do with just
a

visual check.
Driving

93
F If you have a compressor (for example the
one provided in the temporary puncture
repair kit), check the pressure of all four
tyres. If it is not possible to do this check
immediately, drive carefully at reduced
speed.

F

I
n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
The alert is kept active until the system is
reinitialised.
Reinitialisation
Before reinitialising the system, ensure
that the pressures of the four tyres
are correct for the conditions of use
of the vehicle and conform to the
recommendations on the tyre pressure
label.
The under-inflation alert can only be relied
on if the reinitialisation of the system has
been done with the pressures in the four
tyres correctly adjusted.
The under-inflation detection system
does not give a
warning if a pressure is
incorrect at the time of reinitialisation. The system must be reset with the ignition on

(switch in the " ON" position or " ON" mode) and
the vehicle stationary.

the ignition (switch to " ACC" or " LOCK "
position, or " OFF" m o d e).
The new pressure parameters saved are
treated as reference values by the system.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
The under-inflation alert can only be relied
on if the reinitialisation of the system has
been done with the pressures in the four
tyres correctly adjusted.
The system must be reinitialised after any
adjustment to the pressures of one or more
tyres, and after changing one or more wheels.
A label on the driver's side centre pillar reminds
you of this.

94
Operating fault
The flashing and then fixed
illumination of the under-inflation
warning lamp indicates a fault with
the system.
In this case, under-inflation monitoring of the
tyres is no longer assured.
Have the system checked by a
PEUGEOT
dealer or a
qualified workshop.
After any work has been done on
the system, the pressures of the four
tyres must be checked and the system
reinitialised.
