Malfunction
If a fault occurs with the automatic rain sensitive
wipers, the wipers will operate in intermittent mode.
Contact the dealer network or a qualified workshop.
Do not cover the rain sensor, linked with
the sunshine sensor and located in the top
centre of the windscreen, behind the rear
view mirror.
When using an automatic car wash, switch
off the automatic rain sensitive wipers.
In winter, it is advisable to wait until the
windscreen is completely clear of ice before
activating the automatic rain sensitive wipers.
Windscreen and headlamp
wash
Front screenwashHeadlamp wash
To reduce the fluid consumption of the
headlamp wash, it operates only with
every seventh use of the screenwash or
every 25 miles (40 km) during a given
j o u r n ey.
Low screenwash/headlamp wash
fluid
level
Checking and topping up this fluid should be
done with the engine off.
The fluid level should be checked
regularly, particularly during winter.
For more information on Checking levels and,
in particular, the screenwash/headlamp wash,
refer to the corresponding section.
Special position of the
windscreen wipers
This position permits release of the windscreen
wiper blades.
It is used for cleaning or replacement of the
wiper blades. It can also be useful, in winter, to
release the wiper blades from the windscreen.

Instructions
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal and upright sitting position.
Wear a correctly adjusted seat belt.
Do not leave anything between the occupants
and the airbags (a child, pet, object...), nor fix
or attach anything close to or in the way of
the airbag release trajectory; this could cause
injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly
around the airbags.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work on the airbag systems must be
per formed in the dealer network or by a
qualified workshop.
Even if all of the precautions mentioned
are obser ved, a risk of injury or of minor
burns to the head, chest or arms when an
airbag is deployed cannot be ruled out. The
bag inflates almost instantly (within a few
milliseconds) then deflates within the same
time discharging the hot gas via openings
provided for this purpose.Front airbags
Do not drive holding the steering wheel by its
spokes or resting your hands on the centre
part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fit or attach anything to the steering
wheel or dashboard, this could cause injuries
in case of airbag deployment.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment of the lateral
airbags. For information on the range of seat
covers suitable for your vehicle, contact the
dealer network.
Do not attach anything to or hang anything
from the seat backrests (clothes, etc.) as
this could cause injuries to the thorax or arm
when the lateral airbag is deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary. The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors – risk of malfunction of the lateral
airbags!
Such work must only be done in the dealer
network or by a qualified workshop.
Curtain airbags
Do not attach anything or hang anything to
the roof, as this could cause head injuries
when the curtain airbag is deployed.
If fitted to your vehicle, do not remove the
grab handles installed on the roof, they play a
part in securing the curtain airbags.

In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000 metres of altitude.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2 minutes after the vehicle
comes to a stop, to facilitate its cooling.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid
the audible signal if a genuine DS
AUTOMOBILES towbar is used.

Driving

156
Use the cruise control only where the
driving conditions allow running at a
constant speed for a while and at an
adequate safe distance.
Do not activate the cruise control in urban
areas, in heavy traffic, on winding or steep
roads, on slippery or flooded roads, or in
conditions of poor visibility (heavy rain,
fog, falling snow etc.).
In some circumstances, it may not
be possible to maintain or reach the
programmed speed: towing, vehicle
heavily loaded, steep climb, etc.
The use of mats not approved by the
manufacturer may interfere with the
operation of the cruise control.
To avoid any risk of jamming of the pedals:
-
e
nsure that the mat is positioned
c o r r e c t l y,
-

n
ever place one mat on top of another.Lane departure warning
system
System which detects the involuntary crossing
of longitudinal traffic lane markings on the
ground (solid or broken line).
Sensors, fitted below the front bumper, trigger
a warning if the vehicle drifts over a lane
marking (speed higher than 50 mph (80 km/h)).
This system is particularly useful on motor ways
and main roads.The lane departure warning system
cannot, in any circumstances replace the
need for vigilance on the part of the driver.
It is necessary to obser ve the driving
regulations and take a break every two
hours.
Activation
F When switching on the ignition or with the engine running, press this button to activate
the system; the indicator lamp comes on.
Deactivation
F Press this button again, the indicator lamp goes off.
The status of the system remains in memory
when the ignition is switched off.
Detection
You are warned by the vibration of the driver's
seat cushion:
-

o
n the right-hand side, if the marking on the
road has been crossed on the right,
-

o
n the left-hand side, if the marking on the
road has been crossed on the left.
No warning is given while the direction indicator
is active and for approximately 20 seconds
after the direction indicator is switched off.
A warning may be transmitted if a direction
marking (arrow) or non-standard marking
(graffiti) is crossed.
Malfunction
In the event of a malfunction, the
Ser vice warning lamp comes on,
accompanied by an audible signal
and a message in the screen.
Contact the dealer network or a qualified
workshop.

Detection may be impeded:
- i f the sensors are dirty (mud, snow...),
-

i
f the road markings are not clearly
visible,
-

i
f there is little contrast between the
markings on the road and the road
sur face.Blind spot monitoring
This driving assistance system warns the driver
of the presence of another vehicle in the blind
spot angle of their vehicle (areas hidden from
the driver's field of vision), as soon as this
presents a potential danger. This system is designed to improve safety
when driving and is in no circumstances
a substitute for the use of the interior rear
view mirror and door mirrors. It is the
driver's responsibility to constantly check
the traffic, to assess the distances and
relative speeds of other vehicles and to
predict their movements before deciding
whether to change lane.
The blind spot monitoring system can
never replace the need for vigilance on the
part of the driver.
A warning lamp appears in the door mirror on
the side in question:
- i
mmediately, when being overtaken,
- a fter a delay of about one second, when
overtaking a vehicle slowly.

158
F When switching on the ignition or with the engine running, press this button to activate
the system; the indicator lamp comes on.
Sensors fitted in the front and rear bumpers
monitor the blind spots.
The alert is given by a warning lamp which
comes on in the door mirror on the side in
question as soon as a vehicle – car, lorry, cycle
– is detected.
For this, the following conditions must be met:
-

a
ll the vehicles must be moving in the same
direction,
-

t
he speed of your vehicle is between 7 and
87 mph (12 and 140 km/h),
-

y
ou overtake a vehicle with a speed
difference of less than 6 mph (10 km/h),
-

w
hen a vehicle overtakes you with a speed
difference of less than 16 mph (25 km/h),
-

t
he traffic must be flowing normally, No alert will be given in the following situations:
-

i
n the presence of non-moving objects
(parked vehicles, barriers, street lamps,
road signs, etc.),
-

w
ith vehicles moving in the opposite
direction,
-

d
riving on a winding road or a sharp corner,-

w
hen overtaking or being overtaken by a
very long vehicle (lorry, bus, etc.) which is
also in the rear blind spot and present in the
driver’s front field of vision,
-

w
hen overtaking quickly,
-

i
n very heavy traffic: vehicles detected in
front and behind are confused with a lorry or
a stationary object.
Operation- in the case of an overtaking manoeuvre, if this is prolonged and the vehicle being
overtaken remains in the blind spot,
-

y
ou are driving on a straight or slightly
curved road,
-

F To deactivate the system, press this button again; the warning lamp goes off.
The status of the system remains in memory
when the ignition is switched off.
The system is automatically deactivated
when towing with a towbar approved by
DS AUTOMOBILES.
Malfunction
In the event of a fault, the warning lamp in the
button flashes then goes off.
Contact the dealer network or a qualified
workshop. The system may suffer temporary
interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet sur face
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 with 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
the correct operation of the system.
Parking sensors
This system cannot in any circumstances
replace the need for vigilance on the part
of the driver.
This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.)
entering the detection range of the sensors
located in the bumper.
Certain types of obstacle (post, roadworks
cone, etc.) detected initially will no longer
be detected at the end of the manoeuvre, if
they are located in blind spots in the sensors'
detection range.

Rear parking sensors
The system is switched on by engaging reverse
g e a r.
This is confirmed by an audible signal.
The system is switched off when you come out
of reverse gear.
Audible assistanceVisual assistanceThis supplements the audible signal by
displaying bars in the screen which move
progressively nearer to the vehicle.
When the obstacle is very close, the "Danger"
symbol is displayed in the screen.
Front parking sensors
In addition to 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).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).
The sound emitted by the speaker (front or
rear) indicates whether the obstacle is in
front or behind.
Deactivation/activation of the
front and rear parking sensors
The function is deactivated by pressing this
button. The button indicator lamp comes on.
Pressing this button again reactivates the
function. The button indicator lamp goes off.
The function will be deactivated
automatically if a trailer is being towed or a
bicycle carrier is fitted (vehicle fitted with a
towbar or an approved bicycle carrier).
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
When the distance between the vehicle and
the obstacle becomes less than approximately
thirty centimetres, the audible signal becomes
continuous.

Malfunction
In the event of a system fault when
engaging reverse gear, this warning
lamp is displayed in the instrument
panel and/or a message appears
in the screen, accompanied by an
audible signal (short beep).
Contact the dealer network or a
qualified workshop to have the
system checked.
In bad or wintry weather, ensure that the
sensors are not covered with mud, ice or
snow. When reverse gear is engaged, an
audible signal (long beep) indicates that
the sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking sensor
system.
Reversing camera
This system is a driving aid that does not
replace the need for vigilance on the part
of the driver, who must remain in control of
the vehicle at all times. The green lines represent distances of about
1
and 2 metres beyond the edge of your
vehicle's rear bumper.
The red line represent a distance of about
30 cm beyond the edge of your vehicle's rear
b u m p e r.
The lines displayed in the screen do not
allow the position of the vehicle to be
determined relative to tall obstacles (for
example: vehicles nearby).
Some deformation of the image is normal.
High pressure jet wash
When washing your vehicle, keep the
end of the high pressure lance at least
12 inches (30 cm) away from the camera
lens.
Clean the camera lens regularly using a
soft cloth.
The reversing camera function may be
supplemented with parking sensors.
The reversing camera is activated automatically
when reverse gear is engaged.
The colour visual feedback is done on the
touch screen. The blue lines represent the general direction
of the vehicle.
The blue cur ved lines represent the maximum
turning circle.

Tyre under-inflation
d
etection
The tyre under-inflation detection system
is an aid to driving which does not replace
the need for vigilance on the part of the
driver. This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
Tyre pressure 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, add 0.3 bar to the values
indicated on the label.
For more information on Identification
markings , including the tyre pressure
label, refer to the corresponding section.
Under-inflation alert
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. This warning is indicated by
continuous illumination of the lamp,
an audible signal and, depending on
the equipment installed, a message
displayed on the screen.
In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.
F

R
educe speed immediately, avoid excessive
steering movements and sudden braking.
F

S
top as soon as it is safe to do so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.
