The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
►  Switch off the ignition then start the engine
again with the "START/STOP" button.
The Stop & Start system requires a 12 V
battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a dealer or a qualified
workshop.
Under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which must
be reinitialised every time the tyre pressures are
adjusted or a wheel changed.
The system triggers an alert as soon as it detects
a drop in the inflation pressure of one or more
tyres.
Under-inflation detection does not replace
the need for vigilance on the part of the
driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high speed,
long journey):
–

w
orsens road-holding.
–

lengthens braking dist
ances.
–

c
auses premature wear of the tyres.
–

increase
s fuel consumption.
The inflation pressures defined for the
vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at
moderate speeds).
Otherwise, add 0.3 bar to the pressures shown
on the label.
Under-inflation alert
This is signalled by the fixed illumination of
this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►  Reduce speed immediately, avoid excessive
steering movements and avoid sudden braking.
►  Stop the vehicle as soon as it is safe to do so.

116
Driving06
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time to
avoid an accident.
After an impact, the function
automatically stops operating. Contact a
dealer or a qualified workshop to have the
system checked.
Collision Risk Alert
This function warns the driver that their vehicle is
at risk of a collision with the vehicle in front, or a
pedestrian or cyclist present in their traffic lane.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the Driving /
Vehicle touch screen menu.
►  Select one of the three pre-defined thresholds:
–

"Distant".
–

“Normal".
–

“Close".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed in
the instrument panel.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions and the
operation of the vehicle (actions on the pedals,
the steering wheel, etc.) to trigger the alert at the
best moment.
Level 1 (orange): visual alert only,
indicating that the vehicle in front is very
close.
The message "Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
indicating that a collision is imminent.
The message "Brake!" is displayed.
Level 3: in some cases, a vibration alert in the
form of micro-braking can be given, confirming
the risk of collision.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or when
the "Close" trigger threshold has been
selected.
Intelligent emergency braking
assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does not
operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates subject to the following
conditions:
– The vehicle's speed does not exceed 37 mph (60
km/h) when a pedestrian is detected.
– The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle or a cyclist
is detected.
– The vehicle's speed is between 6 mph and
53 mph (10 km/h and 85 km/h) (versions with
camera only) or 87 mph (140 km/h) (versions
with camera and radar) when a moving vehicle is
detected.
This warning lamp immediately flashes
(for approximately 10 seconds) when the
function acts on the vehicle’s braking.
With an automatic gearbox or drive selector, in
the event of automatic emergency braking until
the vehicle comes to a complete stop, keep the
brake pedal pressed down to prevent the vehicle
from moving off again.
With a manual gearbox, in the event of automatic
emergency braking until the vehicle comes to a
complete stop, the engine may stall.
The driver can maintain control of the
vehicle at any time by firmly turning the
steering wheel and/or firmly depressing the
accelerator pedal.

Parking sensors
Refer to the General recommendations on the use
of driving and manoeuvring aids.


Using sensors located in the bumper, this
system signals the proximity of obstacles (e.g. pedestrian, vehicle, tree, barrier) present in
their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear, as confirmed by an audible signal.
The system is switched off when you come out of
reverse gear.
Audible assistance

The system signals the presence of obstacles
within the sensors’ detection zone.


Depending on version, in the example shown, only
the obstacles present in the shaded area will be
signalled by the audible assistance.
The proximity information is given by an
intermittent audible signal, the frequency of

118
Driving06
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
Adjusting the audible signalWith DS CONNECT RADIO or DS
CONNECT NAV, pressing this
button opens the window for adjusting the
volume of the audible signal.
Visual assistance

This supplements the audible signal by displaying
bars on the screen that represent the distance
between the obstacle and the vehicle (white:
more distant, orange: close, red: very close).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
Supplementing the rear parking sensors, the front
parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle is
still below 6 mph (10 km/h).
Front parking sensor operation is suspended if
the vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or the vehicle speed exceeds 6 mph (10 km/h).
The sound emitted by the speaker (front
or rear) locates the obstacle relative to
the vehicle, in front or behind it.
Deactivation / Activation
