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.

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
It is set via the Driving / Vehicle touch
screen menu.
The state of the system stays in the memory when
the ignition is switched off.


The rear parking sensors system will be
deactivated automatically if a trailer or
bicycle carrier is connected to a towing device
installed in accordance with the
manufacturer's recommendations.
In this case, the outline of a trailer is displayed
at the rear of the image of the vehicle.
The parking sensors are deactivated while the
Park Assist and DS PARK PILOT functions are
measuring a space.
For more information on the Park Assist or the DS
PARK PILOT, refer to the corresponding section.
When the vehicle is started, the visual and
audible aids will be available after the
touch screen has started up.
Operating limits
If the boot is heavily loaded, the vehicle may tilt,
affecting distance measurements.
Malfunction
In the event of a malfunction when shifting
to reverse, this warning lamp comes on on
the instrument panel, accompanied by the display
of a message and an audible signal (short beep).
Contact a dealer or a qualified workshop to have
the system checked.
Reversing camera
Refer to the General recommendations on the use
of driving and manoeuvring aids.
As soon as reverse gear is engaged with the
engine running, this system displays views of your

Practical information07
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
When the particle filter is approaching
saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp
goes off.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Electric parking brake
This system does not require any routine
servicing. However, in case of an issue, do
not hesitate to have the system checked by a
dealer or a qualified workshop.
For more information on the Electric
parking brake, refer to the corresponding
section.
Brake pads
Brake wear depends on the style of driving,
particularly in the case of vehicles used in
town, over short distances. It may be necessary to
have the condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads are
worn.
After washing the vehicle, moisture, or in
wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a dealer or a qualified
workshop.
Wheels and tyres
The inflation pressure of all tyres,
including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure label
are valid for "cold" tyres. If you have driven for
more than 10 minutes or more than 6 miles (10
kilometres) at over 31 mph (50 km/h), add 0.3 bar
(30 kPa) to the values indicated on the label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer

After changing a wheel

With a "space-saver" type spare wheel
Deactivate certain driving aid functions
(Active Safety Brake, Adaptive cruise control,
etc.).
Do not exceed the maximum authorised speed
of 50 mph (80 km/h).
Driving with more than one “space-saver” type
spare wheel is prohibited.
Visit a dealer or a qualified workshop as
soon as possible to have the tightness of
the bolts and the pressure of the spare wheel
checked.
Have the punctured tyre examined. After
inspection, the technician will advise you on
whether the tyre can be repaired or if it must
be replaced.
Changing a bulb
In some weather conditions (e.g. low
temperature or humidity), the presence of
misting on the internal surface of the glass of
the headlamps and rear lamps is normal; it
disappears after the lamps have been on for a
few minutes.
The headlamps have polycarbonate
lenses with a protective coating:
–

Do not clean them with a dry or abrasiv
e
cloth, nor with detergent or solvent products.
–

U

se a sponge and soapy water or a pH
neutral product.
–

When using a high-pre
ssure washer on
persistent marks, do not keep the lance
directed towards the headlamps, lamps or
their edges for too long, so as not to damage
their protective coating and seals.
Changing a bulb must only be done with
the ignition off and after the headlamp /
lamp has been switched off for several
minutes - risk of serious burns!
Do not touch the bulb directly with your
fingers; use a lint-free cloth.
It is essential only to use anti-ultraviolet (UV)
type bulbs, so as not to damage the headlamp.
Always replace a failed bulb with a new bulb
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
After changing a bulb
To refit, carry out the operations in
reverse order to removal.
Close the protective cover very carefully to
guarantee the sealing of the lamps.
