– Jolting and knocking noise during hill starts.
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 heating up.
In all cases, pay 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
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use of
engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine immobiliser
system, with a code that must be recognised in
order for starting to be 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.
For versions equipped with Proximity Keyless
Entry and Start, the electronic key is also
detected in the boot.
If it is not detected, a message is displayed.
Move the electronic key so that the engine can
be started or switched off.
If there is still a problem, refer to the "Key not
detected - Back-up starting or Back-up switch-
off" section.

Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again.
►  With a manual gearbox: with the clutch pedal
fully depressed.
►  With an automatic gearbox:
•

With the select
or in position D or M: with the
brake pedal released.
•

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

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

R
everse gear engaged.
Special cases
The engine restarts automatically if all the
operating conditions are met again and in the
following cases.
–
With a manual gearbo
x: vehicle speed exceeds
2.5 mph (4 km/h),
–

With an aut
omatic gearbox, in mode N, vehicle
speed exceeds 0.6 mph (1 km/h).
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
Malfunctions
In the event of a malfunction, this warning
lamp flashes for a few moments, then
remains on, accompanied by an onscreen
message.
Have the vehicle 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.
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.

Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or masked
by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a dealer or a qualified workshop
to recalibrate the camera; otherwise, the
operation of the associated driving aids may
be disrupted.
Other cameras
The images from the camera(s) displayed
on the touch screen or on the instrument panel
may be distorted by the relief.
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
the associated functions may be disturbed
by sound interference 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
The use of mats 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
in 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.
Speed Limit Recognition
and Recommendation
Refer to the General recommendations on the use
of driving and manoeuvring aids.

Malfunction
If the event of malfunction, this warning
lamp comes on in the instrument panel,
accompanied by the display of a message.
Contact a dealer or a qualified workshop to have
the system checked.
The system may suffer temporary
interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet surface or
moving from a dry area to a wet area can
cause false alerts (for example, the presence
of a fog of water droplets in the blind spot
angle is 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
or other objects; they may hamper correct
operation of the system.
Active Blind Spot
Detection
In addition to the fixed warning lamp in the door
mirror on the side in question, a correction of
trajectory will be felt if you attempt to cross
a lane marking with the direction indicator
activated, to help you avoid a collision.
This system is the combination of the Active
Lane Departure Warning System and Blind Spot
Detection.
These two functions must be activated and in
operation.
The speed of the vehicle must be between 40 and
87 mph (65 and 140 km/h).
These functions are especially suitable for driving
on motorways and main roads.
For more information on the Active Lane
Departure Warning System and Blind Spot
Detection, refer to the corresponding sections.
Active Safety Brake with
Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the use
of driving and manoeuvring aids.


This system:
– warns the driver that their vehicle is at risk of
collision with the vehicle in front, a pedestrian or,
depending on version, a cyclist.
– reduces the vehicle's speed to avoid a collision
or limit its severity.
The system also takes motorcyclists and
animals into account; however, animals
below 0.5 m tall and objects on the road are
not necessarily detected.
This system is comprised of three functions:
– Collision Risk Alert.
– Intelligent emergency braking assistance.
– Active Safety Brake (automatic emergency
braking).

117
Driving06
Operation
The system operates subject to the following
conditions:
–

The v
ehicle's speed does not exceed 37 mph (60
km/h) when a pedestrian is detected.
–

The v
ehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle or a cyclist
is detected.
–

The v
ehicle'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.
The brake pedal may vibrate slightly while
the function is operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.
Malfunction

are alerted by the fixed illumination of this
warning lamp, accompanied by the display of a
message and an audible signal.
Contact a dealer or a qualified workshop to have
the system checked.
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.
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
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

119
Driving06
vehicle’s close surroundings on the touch screen
using a camera located at the rear of the vehicle.




The screen is divided into two parts with a
contextual view and a view from above the vehicle
in its close surroundings.
The parking sensors supplement the information
on the view from above the vehicle.
Various contextual views may be displayed:
–
St
andard view.
–

180° vie

AUTO mode is activated by default.
In this mode, the system chooses to display the
best view (standard or zoom).
You can change the type of view at any time
during a manoeuvre.
The state of the function is not saved when the
ignition is switched off.
Principle of operation

Using the rear camera, the vehicle's close
surroundings are recorded during manoeuvres at
low speed.
An image from above your vehicle in its close
surroundings is reconstructed (represented
between the brackets) in real time and as the
manoeuvre progresses.
It facilitates the alignment of your vehicle when
parking and allows obstacles close to the vehicle
to be seen. It is automatically deleted if the
vehicle remains stationary for too long.
Rear vision

To activate the camera, located on the tailgate,
engage reverse and keep the speed of the vehicle
below 6 mph (10 km/h).
The system is deactivated:
–

AUTO mode

This mode is activated by default.
Using sensors in the rear bumper, the automatic
view changes from the rear view (standard) to
the view from above (zoom) as an obstacle is
approached at the level of the red line (less than
30 cm) during a manoeuvre.
Standard view

The area behind the vehicle is displayed on the
screen.The blue lines 1 represent the width of your
vehicle, with the mirrors unfolded; their direction
changes according to the position of the steering
wheel.
The red line 2 represents a distance of 30 cm
from the rear bumper; the two blue lines 3 and 4
represent 1 m and 2 m, respectively.
This view is available with AUTO mode or in the
view selection menu.
Zoom view

The camera records the vehicle's surroundings
during the manoeuvre in order to create a
view from above the rear of the vehicle in its
near surroundings, allowing the vehicle to be
manoeuvred around nearby obstacles.
This view is available with AUTO mode or in the
view selection menu.
Obstacles may appear further away than
they actually are.
It is important to monitor the sides of the
vehicle during the manoeuvre, using the
mirrors.
Parking sensors also provide additional
information about the area around the vehicle.
180° view

The 180° view facilitates reversing out of a
parking space, making it possible to see the
approach of vehicles, pedestrians and cyclists.
This view is not recommended for carrying out a
complete manoeuvre.
It features 3 areas: left A, centre B and right C.
This view is only available via the view selection
menu.
Park Assist
Refer to the General recommendations on the use
of driving and manoeuvring aids.
This system provides active parking assistance
for vehicles fitted with a manual gearbox: it
detects a parking space and then steers in
the appropriate direction to park in this space
while the driver controls the driving direction,
engagement of gears, acceleration and braking.
To assist the driver in monitoring the correct
manoeuvring operation, the system automatically
triggers the display of Reversing camera and the
activation of the parking sensors.
The system performs the measurements of
available parking spaces and calculations of
distances to obstacles using ultrasonic sensors
built into the front and rear bumpers of the
vehicle.


The system assists with the following
manoeuvres:
