The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work on this type of battery must only
be carried out in the dealer network or by
a qualified workshop.
For more information on the 12 V batter y ,
refer to the corresponding section.
Opening the bonnet
Driving on flooded roads
Before driving in a flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving advice ,
particularly on flooded roads, refer to the
corresponding section. Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from an
automatic change to START mode.Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
This system only operates when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

w
ith the driver’s door closed.
The hill start assist function cannot be
deactivated.
Operation
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal:
-

i
f you are in first gear or neutral with a
manual gearbox, On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamps light up constantly on
the instrument panel.
-
i
f you are in position D or M with an
automatic gearbox.

Operating fault
If a fault in the system occurs, these warning
lamps come on. Contact the dealer network
or a qualified workshop to have the system
checked.
Memorising speeds
This function allows speeds to be saved, which
can then be offered to set the two systems: the
speed limiter (to limit the speed of the vehicle)
or the cruise control (for a vehicle cruising
speed).
You can memorise up to five or six speed
settings in the system, depending on version.
Default speed settings have already been
stored.As a safety measure, the driver must only
modify a speed setting when stationary.

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.

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,
-

y
our vehicle is not pulling a trailer,

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.

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.
