► Do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, contact
a dealer or a qualified workshop.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
►  Distribute the load in the trailer so that the
heaviest items are as close as possible to the axle
and the nose weight (at the point where it joins
your vehicle) approaches the maximum permitted
without exceeding it.
Tyres
►  Check the tyre pressures of the towing vehicle
and of the trailer, observing the recommended
pressures.
Lighting
►  Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine towing device is used, the
rear parking sensors will be deactivated
automatically to avoid the audible signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►  Reduce speed and lower the engine speed to
limit the amount of heating produced.
►  Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a dealer.
Starting/switching off the
engine
The electronic key must be present in the
passenger compartment.
If the electronic key is not detected, a message
is displayed.

Driving06
The system uses a computer and sensors, which
determine the optimal level of shock absorption
to be applied to each shock absorber.
The system is also associated with a camera,
located at the top of the windscreen, constantly
monitoring the road condition. Based on the
information transmitted by the camera, the
system anticipates possible road defects.
The operation of the system depends on the
driving mode selected (depending on equipment).
For more information on the Driving modes,
please refer to the corresponding section.
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel.
Have it checked by a dealer or a qualified
workshop.
Driving modes
The driving modes available depend on the engine
and equipment of the vehicle.
Driving modes are selected using the following
control:




►  Press the control to display the modes on the

gearbox, gear shift indicator.
Free-wheeling in Eco mode: depending on version,
with the EAT8 gearbox, switching into "free-
wheeling" is encouraged to slow the vehicle down
without using engine braking. You can save fuel
by taking your foot gradually and fully off the
accelerator pedal in anticipation of slowing down.
Comfort
To achieve more comfortable driving on poor
road surfaces, over speed humps and sleeping
policemen or on long journeys. In this mode, DS

– The outside temperature must be between 0°C
and 35°C.
Putting the engine into standby (STOP
mode)
The engine automatically enters standby mode
as soon as the driver indicates their intention to
stop:
–

With an automatic gearbo
x, at speeds below
12 mph (20 km/h) on BlueHDi versions, or below
2 mph (3 km/h) on PureTech 130, 180 and 225
versions, when you depress the brake pedal or
place the gear selector in mode N.
Time counter
A time counter adds up the time spent in standby
during the journey. It is reset to zero every time
the ignition is switched on.
Special cases:
The engine will not go into standby if the
conditions for operation are not met and in the
following cases:
–

St
eep slope (ascending or descending).
–

Needed t
o maintain a comfortable temperature
in the passenger compartment.
–

Demisting activ
e.
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
After the engine has restarted, STOP
mode is not available until the vehicle has
reached a speed of 5 mph (8 km/h).
During parking manoeuvres, STOP mode is
not available for a few seconds after
coming out of reverse gear or turning the
steering wheel.
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again:
–

With the select
or in mode D or M: with the
brake pedal released.
–

With the select
or in mode N and the brake
pedal released: with the selector at D or M.
–

With the select
or in mode P and the brake pedal
depressed: with the selector at R, N, D or M.
–

With re
verse gear engaged.
Special cases
The engine will restart automatically if the
conditions for operation are met again and in the
following cases:
–
V
ehicle speed exceeds 2.5 mph (4 km/h) with
PureTech 130, 180 and 225 versions, or 16 mph
(25 km/h) with BlueHDi versions.
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
Malfunctions
In the event of a fault with the system, this
warning lamp flashes for a few moments
on the instrument panel, then remains on,
accompanied by the display of a message.
Have it checked by a dealer or a qualified
workshop.
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.
12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a dealer or
a qualified workshop.
Tyre under-inflation
detection
This system alerts the driver if one or more tyres
suffer a drop in pressure.
The alert is raised when the vehicle is moving, not
when stationary.
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.
It takes into account the last values stored
during the reinitialisation request. It is therefore
essential that the tyre pressure is correct during
the operation. This operation is the driver’s
responsibility.

111
Driving06
The tyre under-inflation detection cannot,
in any circumstances, 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), especially 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 energy 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 monthly 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.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
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.
The loss of pressure detected may not
always cause visible deformation of the
tyre.
Do not rely on just a visual check.
►  Using a compressor, such as the one in
the temporary puncture repair kit, check the
pressures of all four tyres when cold.
►  If it is not possible to carry out this check
immediately, drive carefully at reduced speed.
►  In the event of a puncture, use the temporary
puncture repair kit or the spare wheel (depending
on equipment).
Driving too slowly may not ensure
optimum monitoring.
The alert is not immediately triggered in the
event of a sudden loss of pressure or tyre blow-
out. This is because analysis of the values read
by the wheel's speed sensors can take several
minutes.
The alert may be delayed at speeds below 25
mph (40 km/h), or when adopting a sporty
driving mode.
The alert is kept active until the system is
reinitialised.
Reinitialisation
►  The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With the vehicle stationary, the system
can be reinitialised in the Settings>Vehicle
touch screen application.
►  Then select Safety > Tire Pressure Setup.
►  Press YES to confirm.
The reinitialisation is confirmed by the display of
a message and an audible signal.

113
Driving06
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors, as well as
any associated functions, may be disrupted by
noise pollution such as that emitted by noisy
vehicles and machinery (e.g. lorries, pneumatic
drills), by the accumulation of snow or dead
leaves on the road or in the event of damaged
bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer be
detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away from
the radar, sensors and cameras.
Mats/Pedal trims
The use of mats or pedal trims not
approved by the Manufacturer may interfere
with the operation of the speed limiter or
cruise control.
To avoid any risk of jamming the pedals:
–

Ensure tha
t the mat is secured correctly.
–

Ne
ver fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
on the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a dealer or a qualified
workshop.
Shortcuts for driving aids
The full list of available driving aids can be found
in the Functions tab. Driving aids can be accessed directly to quickly
activate/deactivate them.
By default, driving aids are already stored in the

Driving06
This is a normal behavior indicating that a
condition is not fulfilled and which does not
request the support of a workshop.
In any situations with ignition on where automatic
braking presents a risk, deactivating the system
via the driving aids touch screen application is
recommended, for instance:
–

T
owing a trailer (particularly a trailer without
its own braking system).
–

Carrying long objects on roo
f bars.
–

D
riving with snow chains.
–

U
sing an automatic car wash.
–

Performing an
y maintenance (e.g. changing a
wheel, working inside the engine compartment).
–

Placing the v
ehicle on a rolling bench in a
workshop.
–

T
owing the vehicle.
–

Follo
wing an impact to the windscreen close to
the detection camera.
The system is automatically deactivated
once the use of a different diameter
"space-saver" type spare wheel is detected, or
if a fault with the two lateral brake lamps is
detected.
The system diagnoses permanently its
capability and may inhibit itself without
specific driver indication, if the system is
outside of the regular operating conditions
(e.g. sensor initialization, board voltage out of
regular range, activation of stability system).
Therefore, the system may not be available
just after starting the vehicle.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not overload the vehicle
(keep within the GVW limit and load
height limits for roof bars).
Following an impact (e.g.  a collision), the
system is automatically deactivated.
Have it checked by a dealer or a qualified
workshop.
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
It is configured in the ADAS touch screen
application.
►  Select one of the 3 preset
thresholds: "Far ", "Medium" or "Near".
The selected threshold is memorised when the
ignition is switched off.
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own vehicle
and the object identified for the collision risk, and
the operation of the vehicle (e.g. actions on the
pedals, steering wheel) to trigger the alert at the
most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake!" is displayed.
Level 3: a micro-braking may be given, confirming
the risk of collision (optional).
While approaching a vehicle too quickly,
the level 2 alert may be displayed directly.
Important: the level 1 alert depends on the
trigger threshold selected. It reacts only on
moving vehicles. It is disabled automatically at
lower speed.

131
Driving06
Malfunction
This warning lamp lights up on the
instrument panel with the message
"Sensor blind" in certain cases.
Version with camera only: the system is
deactivated.
Version with camera and radar: the system may
continue to operate in a degraded mode.
This may be caused by a reduced visibility
(e.g. rain, fog, snow, blinding by low sun) or by a
real sensor blockage. In this case, stop the vehicle
and verify if the front camera or the front radar is
covered by dirt, snow, ice or anything preventing
the sensing.
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and an
audible signal.
Have it checked by a dealer or a qualified
workshop.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a dealer or a
qualified workshop to have the system checked.
These warning lamps light up on
the instrument panel and/or in the
warning lamp display for seat belts and front
passenger airbag to indicate that the driver's and/
or front passenger's seat belt is not fastened
(depending on version). The automatic braking
system is deactivated until the seat belts are
fastened.
Distraction detection
For more information, refer to the General
recommendations on the use of driving
and manoeuvring aids.
The function comprises the "Driver Attention
Warning" and "Driver Attention Warning by
Camera" systems, combined, depending on
version, with the "DS DRIVER ATTENTION
MONITORING" system.
These systems are in no way designed to
keep the driver awake or to prevent the
driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Take a break if you are feeling tired or at least
every 2 hours.
Activation/Deactivation
By default, the function is automatically activated
at every engine start.
The settings are changed via the ADAS
touch screen application.
Driver Attention Warning
The system triggers an alert when it
detects that the driver has not taken a
break after two hours of driving at a speed above
43 mph (70 km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
–

With the engine running, the v
ehicle has been
stationary for more than 15 minutes.
–

The ignition has been s
witched off for a few
minutes.
–

The driv
er's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops
below 43 mph (70 km/h), the system goes
into standby.
Driving time starts being counted again once
the speed reaches above 43 mph (70 km/h).

stationary object.
Malfunction
If the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message.
Have it checked by a dealer or a qualified
workshop.
The system may be temporarily disturbed
by certain weather conditions (e.g. rain,
hail).
In particular, driving on a wet road or going
from a dry to a wet area can cause false alerts
(e.g. presence of a cloud of water droplets in
the blind spot interpreted as a vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in the
door mirrors, or the detection zones on the
front and rear bumpers with adhesive labels
