Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears.
You can follow this instruction without going
through the intermediate gears.
Gear shift indicator
System which reduces fuel consumption by recommending the most suitable gear.The system adapts its gear change
recommendation according to the
driving conditions (gradient, load,
...)
and the demands of the driver (power,
acceleration, braking,
...).
The system never suggests:
-

e
ngaging first gear,
-
enga

ging reverse gear.
-
c

hanging down.
The information appears in the instrument
panel in the form of an arrow.
On vehicles with manual gearbox, the arrow
may be accompanied by the recommended
g e a r.
The gear engagement recommendations
must not be considered compulsory.
This is because the configuration of the
road, traffic density and safety remain
impor tant factors in the choice of the best
g e a r.
The gear shift indicator system does not
replace the need for vigilance on the part of the
driver. With an automatic gearbox, the system is only active in manual mode.
On BlueHDi Diesel 135 and 150 versions with
manual gearbox, in certain driving conditions
the system may suggest changing into neutral
so that the engine can go into standby (STOP
mode with Stop & Start). In this case, N is
displayed in the instrument panel. Example:
This function cannot be deactivated.

Stop & Start
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, etc.). The engine
restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.

If your vehicle is fitted with the system, a time
counter calculates the sum of the periods in
STOP mode during a journey. It resets itself to
zero every time the ignition is switched on with
the START/STOP button. Never refuel with the engine in STOP
mode; you must switch off the ignition
with the START/STOP button. For your comfort, during parking
manoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
The Stop & Start system does not affect
the functionality of the vehicle, such as
for example, braking, power steering...
Special cases: STOP mode not
available
STOP mode is not invoked when:
-
t he driver's door is open,
-

t
he driver's seat belt is not fastened,
-

Have it checked by a CITROËN dealer or a
qualified workshop.
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 place the gear selector
lever at position N and put your foot on the brake
pedal.
It is then necessary to switch off the ignition and
start the engine again using the "START/STOP"
button.
In the event of a fault with the system,
this indicator lamp flashes for a few
moments then comes on continuously,
accompanied by a message.
Opening the bonnet
Before doing anything under the
bonnet, deactivate the Stop & Start
system to avoid the risk of injury related
to an automatic change to START
mode.
Driving on flooded roads
Before driving through a flooded road,
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. The Stop & Start system requires a
battery of advanced technology and
special characteristics.
All work on this type of battery must
only be done by a CITROËN dealer or a
qualified workshop.

Dynamic cruise control
System that allows, in addition to maintaining your vehicle's speed at a value that you have defined, the inter-vehicle time you have selected between
your vehicle and the one in front to be maintained.
Principles of operation
Using a radar with a range of about 100 metres,
located at the front of the vehicle, this system
detects a vehicle running in front of your
vehicle.
It automatically adapts the speed of the vehicle
to that of the vehicle in front.
If the vehicle in front is running more slowly,
the system progressively reduces the speed of
your vehicle using just engine braking (as if the
driver had pressed the "-" button).
If your vehicle is too close to or approaching
the vehicle in front too quickly, the dynamic
cruise control is automatically deactivated.
The driver is then alerted by an audible signal,
accompanied by a message.
Choice of the type of cruise control
The choice between the "dynamic" and
"standard" cruise control is done in the Driving
menu.
F

I
n the Driving menu, select the " Driving
functions " tab, then " Active cruise
control" to activate or deactivate the
dynamic cruise control.
For more information on the Cruise
control , refer to the corresponding
section. F

P
lace the cruise control
thumbwheel at "CRUISE". If the vehicle in front accelerates or changes
lane, the dynamic cruise control progressively
accelerates your vehicle to return to the
programmed speed.
If the driver operates a direction indicator to
the left (left-hand drive) or the right (right-
hand drive), to overtake a slower vehicle, the
dynamic cruise control allows your vehicle to
temporarily approach the vehicle in front to
assist the overtaking manoeuvre, though never
exceeding the programmed speed.
Driving

163
C4-Picasso-II_en_Chap04_conduite_ed02-2016
The dynamic cruise control is switched on
manually: it requires that the speed of the
vehicle be between 25 and 90 mph (40 and
150
km/h), as well as the engagement of:
-

f
ourth gear or higher with a manual
gearbox,
-

s
econd gear or higher with an automatic
gearbox in manual mode,
-
position D with an automatic gearbox.
The system remains active after changing gear
on vehicles with a manual gearbox and Stop &
Start.
General points
The dynamic cruise control can be paused
manually or automatically:
-

b
y pressing button 4 ,
-

b
y pressing the brake pedal,
-

i
n the event of operation of the ESC, for
safety reasons,
-

i
n the event of operation of the electric
parking brake control lever,
-

w
hen an inter-vehicle time threshold is
reached (calculated according to the
relative speeds of your vehicle and the
vehicle in front and the inter-vehicle time
setting chosen),
-

w
hen the distance between your vehicle
and the one in front becomes too small,
-

w
hen the speed of the vehicle in front is
too


low,
-

w
hen the speed of your vehicle becomes
too low.
The dynamic cruise control cannot in any
circumstances replace the observation
of speed limits, nor the need for vigilance
on the part of the driver.
It is recommended that you always keep
your feet close to the pedals. If the speed setting selected is above
90 mph (150 km/h), the system switches
to standard cruise control operation,
with no adjustment of the inter-vehicle
safe distance (a message appears in
the instrument panel). The inter-vehicle time setting is kept in
memory on switching off the ignition.
The dynamic cruise control operates by
day and at night, in fog or in moderate
rainfall.
The system does not act on the braking
system, but works only with engine braking.
The regulation range is limited: there will
no longer be any adjustment of speed if the
difference between the programmed speed
setting and the speed of the vehicle in front
becomes too high (18 mph (30 km/h)).
If the difference between the
programmed speed setting and the
speed of the vehicle in front is too
great, the speed cannot be adjusted:
the cruise control is automatically
deactivated.

instrument panel Associated message
Comments
No vehicle detected:
the system operates as a standard cruise control.
Detection of a vehicle, at the limit of the range of the radar:
the system operates as a standard cruise control.
"SPEED ADJUSTED" Detection of a vehicle that is too close or running at a speed lower than your
vehicle's cruise speed setting.
The system uses engine braking to slow your vehicle and then hold it at the speed of
the vehicle in front so as to maintain the programmed inter-vehicle time.
The regulation range is limited to a maximum difference of 20 mph (30 km/h)
between the speed setting and the speed of the vehicle ahead.
"SPEED ADJUSTED" When the adjusted speed reaches the control limit (speed setting - 20 mph
(30
km/h)), the adjusted speed flashes together with the speed setting, to signal that
automatic deactivation of the system is imminent.
"Cruise control
paused" If the system exceeds the limit of speed adjustment possible by the system and
in the absence of any reaction by the driver (operation of the direction indicator,
change of lane, reduction of the speed of the vehicle), the system is automatically
paused.
The display of the deactivation message is accompanied by an audible signal.
Driving situations and associated alerts
The table below describes the alerts and the messages displayed for the different driving situations.
The display of these alerts is not sequential.

When the dynamic cruise control is
automatically paused, it can only be
reactivated when safe conditions are
restored. The message "Activation
not possible, conditions unsuitable"
is displayed while reactivation is not
possible.
When the conditions allow, it is
recommended that the system be
reactivated by pressing button 2 or 3,
which will make the current speed of
your vehicle the new cruise speed
setting, rather than by pressing button 4
(on/pause) which reactivates the system
using the old cruise speed setting,
which may be very different from the
current speed of your vehicle. The dynamic cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle loses speed slowly, as when releasing
the accelerator pedal.
The system is paused automatically:
-

i
f the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
-

i
f a vehicle comes between your vehicle
and the vehicle in front,
-

i
f the system does not slow the vehicle
enough to continue to maintain a safe
distance, for example when descending a
steep hill.
Limits of operation
As the radar's field of view is quite narrow, it is
possible that the system may not detect:
The cruise control does not take account of:
-
s

tationary vehicles,
-

v
ehicles driving in the opposite direction.
-

v
ehicles of reduced width, such as
motorcycles,
-

v
ehicles not running in the middle of the
lane,
-

v
ehicles entering a corner,
-

v
ehicles changing lane at the last moment.
The regulation range is limited to a maximum
difference of 20 mph (30 km/h) between the
speed setting and the speed of the vehicle in
front. Above this, the system goes into pause if
a safe distance is not maintained.
Severe weather conditions (very heavy
rain, accumulations of snow in front
of the radar) can inter fere with the
operation of the system, resulting in
the display of the message "SYSTEM
INACTIVE: Visibility reduced". The
function remains unavailable until the
message disappears.
