Going into engine START mode

With a manual gearbox, this
warning lamp switches off and the

Special cases: START invoked

automatically

With a manual gearbox in STOP mode,
if a gear is engaged without fully
depressing the clutch pedal, a warning
lamp comes on or an alert message
is displayed asking you to depress the
clutch pedal to restart the engine.

In this case the "ECO"

warning lamp

flashes for few seconds, then goes
off.

This operation is perfectly normal.

For safety reasons or to ensure smooth
operation, START mode is invoked
automatically when:
- you open the driver's door,
- you unfasten the driver's seat belt,
- the speed of the vehicle exceeds 15 mph

(25 km/h) with a manual gearbox (3 km/h
(2 mph) with PureTech 130 petrol and
BlueHDi Diesel 115 and 120 versions) or
2 mph (3 km/h) with an automatic gearbox,

- the electric parking brake is being applied,
- some special conditions (battery charge,

engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.

With an automatic gearbox, this
warning lamp switches off and the

engine restarts automatically when:
- you release the brake pedal with the gear

selector in position D or M,

-

you are in position N

, with the brake pedal

released, and you place the gear selector
in position D or M,

- you engage reverse gear.

engine restarts automatically when you press
the clutch pedal fully.

Operating fault

In some cases, such as the maintaining of a
comfortable temperature in the passenger
compartment, it may be useful to deactivate the
Stop & Start.
Deactivation can be requested at any time once
the ignition has been switched on.
If the engine is in STOP mode, it restarts
straight away.
The Stop & Start is reactivated automatically
each time the ignition is switched on.

Deactivation / Reactivation

In the event of a fault in STOP mode, the
vehicle may stall. All of the instrument panel
warning lamps come on.
Depending on version, an alert message may
also be displayed asking you to put the gear
lever into position N

and put your foot on the

brake pedal.
It is then necessary to switch off the ignition,
then restart the engine.

The Stop & Start requires a 12 V
battery with special technology and
specifications. All work on this type of
battery must be carried out exclusively
by a CITROËN dealer or a qualified
workshop.
For more information on the 12 V
battery

, refer to the corresponding

section.

In the event of a malfunction with
the system, the "ECO OFF" switch
warning lamp flashes, then comes on
continuously.

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 motorways
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 observe driving
regulations and take a break every
two hours.

Deactivation

F

Press this button again, the indicator lamp

goes off.

The status of the system remains in the
memory when the ignition is switched off.

No warning is transmitted 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 (e.g. arrow) or non-standard marking
(e.g. graffiti) is crossed.

Operating fault

The detection may be impeded:
- if the sensors are dirty (mud, snow...),
- if the markings on the ground are

worn,

-

if there is little contrast between
the markings on the ground and
the road surface.

In the event of a malfunction, the
service warning lamp comes on,
accompanied by an audible signal
and a message in the screen.

Contact a CITROËN dealer or a qualified
workshop.

Activation

F

When switching the ignition on or with

the engine running, press this button; the
indicator lamp comes on.

Detection

You are warned by the vibration of the driver's
seat cushion:
- on the right-hand side, if the marking on

the ground has been crossed on the right,

- on the left-hand side, if the marking on the

ground has been crossed on the left.

Blind spot monitoring system

This driving assistance system warns the driver
of the presence of another vehicle in the blind
spot angle of their vehicle (areas masked from
the driver's field of vision), as soon as this
presents a potential danger.

Operation

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 sensor system can never replace the need for vigilance on the part of
the driver.

F

On switching on the ignition, or engine

running, press this button to activate the
function; the warning lamp comes on.

Sensors fitted in the front and rear bumpers
monitor the blind spots.

A warning lamp appears in the door mirror on
the side in question:
- immediately, when being overtaken,
- after a delay of about one second, when

overtaking a vehicle slowly.

06

211

Driving

DS4_en_Chap06_conduite_ed01-2016

No alert will be given in the following situations:
- in the presence of immobile objects

(parked vehicles, barriers, street lamps,
road signs...),

- with vehicles moving in the opposite

direction,

- driving on a sinuous road or a sharp

corner,

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:
- all the vehicles must be moving in the

same direction,

- the speed of your vehicle is between 7 and

75 mph (12 and 140 km/h),

- when you overtake a vehicle with a speed

difference of less than 6 mph (10 km/h),

- when a vehicle overtakes you with a speed

difference of less than 15 mph (25 km/h),

- the traffic must be flowing normally,
- in the case of an overtaking manoeuvre,

if this is prolonged and the vehicle being
overtaken remains in the blind spot,

- you are driving on a straight or slightly

curved road,

- your vehicle is not pulling a trailer, a

caravan...

- when overtaking (or being overtaken by) a

very long vehicle (lorry, coach...) which is
at the same time detected at the rear in the
blind spot angle and present in the driver's
forward field of vision,

- in very heavy traffic: vehicles detected in

front and behind are confused with a lorry
or a stationary object,

- when overtaking quickly.

06

Driving

DS4_en_Chap06_conduite_ed01-2016

Operating fault

The system may suffer temporary
interference in certain weather
conditions (rain, hail...).
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 the correct
operation of the system.

F

To deactivate the system, press this button

again; the warning lamp goes off.

The state of the system remains in memory on
switching off the ignition.

The system is automatically
deactivated when towing with a towbar
approved by CITROËN.

In the event of a fault, the warning lamp in the
button flashes then goes off.
Have it checked by a CITROËN dealer or a
qualified workshop.

Parking sensors

This system indicates the proximity of an
obstacle (e.g. pedestrian, vehicle, tree, gate)
which comes within the field of detection of
sensors located in the bumper.
Certain types of obstacle (e.g. stake,
roadworks cone) detected initially will no longer
be detected at the end of the manoeuvre, if
they are located in blind spots in the sensors'
field of detection.

This system cannot in any circumstances replace
the need for vigilance on the part of the driver.

The system is switched on by engaging reverse
gear.
This is confirmed by an audible signal.
The system is switched off when you come out
of reverse gear.

Rear parking sensors

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-hand or
left-hand) 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.

Visual assistance

Audible assistance

This 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

Operating fault

In the event of a malfunction of the
system, when reverse gear is engaged
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 a CITROËN dealer or a
qualified workshop.

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 forward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).

The function will be deactivated
automatically if a trailer is being towed
or a bicycle carrier is fitted (vehicle
fitted with a towbar or bicycle carrier
recommended by CITROËN).

In bad weather or in winter, 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.

Deactivation/Activation of the front

and rear parking sensors

The function is deactivated by pressing this
button. The indicator lamp in the button
comes on.
Pressing this button again reactivates the
function. The indicator lamp in the button
goes off.

The sound emitted by the speaker
(front or rear) indicates whether the
obstacle is in front or behind.
