Cruise control - "CRUISE"

System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal.

The cruise control system cannot, in any circumstances, replace the need to observe speed limits, nor can it replace the need for vigilance on the part of the driver.
You are advised to keep your feet near the pedals at all times.

Switching on the cruise control requires a
minimum vehicle speed of 25 mph (40 km/h).
As well as engagement of:
- fourth gear or higher on a manual gearbox,
- second gear or higher in manual mode on

an automatic gearbox,

- position

on an automatic gearbox.

The system remains active after changing gear
on vehicles with a manual gearbox and Stop &
Start.
The cruise control is paused

by pressing

button 4

or the brake pedal or on triggering of

the ESC system for safety reasons.
It is possible to exceed the programmed speed
temporarily by pressing the accelerator pedal.
To return to the programmed speed, simply
release the accelerator pedal until the
programmed cruise speed is reached again.

Select cruise control mode.

Driving

C4-Picasso-II_en_Chap04_conduite_ed02-2016

Flashing of the dashes indicates a fault with the
cruise control.
Have it checked by a CITROËN dealer or a
qualified workshop.

Operating fault

When the cruise control is switched on,
be careful if you maintain the pressure
on one of the programmed speed
changing buttons: this may result in a
very rapid change in the speed of your
vehicle.
Do not use the cruise control on
slippery roads or in heavy traffic.
On a steep descent, the cruise control
will not be able to prevent the vehicle
from exceeding the programmed speed.
On steep climbs or when towing, the
programmed speed may not be reached
or maintained.
The use of mats not approved by
CITROËN may interfere with the
operation of the cruise control.
To avoid any risk of jamming of the
pedals:
- ensure that the mat is secured

correctly,

- never fit one mat on top of another.

Driving

C4-Picasso-II_en_Chap04_conduite_ed02-2016

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 In 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 Place 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.

163

Driving

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:
- fourth gear or higher with a manual

gearbox,

- second gear or higher with an automatic

gearbox in manual mode,

- position

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:
- by pressing button 4,
- by pressing the brake pedal,
-

in the event of operation of the ESC, for
safety reasons,

in the event of operation of the electric
parking brake control lever,

- when 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),

- when the distance between your vehicle

and the one in front becomes too small,

- when the speed of the vehicle in front is

too low,

- when 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.

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.

167

Driving

C4-Picasso-II_en_Chap04_conduite_ed02-2016

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:
- if the vehicle in front slows down too much

or too suddenly, and the driver does not
brake,

- if a vehicle comes between your vehicle

and the vehicle in front,

- if 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:
-

stationary vehicles,

- vehicles driving in the opposite direction.

- vehicles of reduced width, such as

motorcycles,

- vehicles not running in the middle of the

lane,

- vehicles entering a corner,
- vehicles 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 interfere 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.

168

Driving

C4-Picasso-II_en_Chap04_conduite_ed02-2016

In the event of a fault with the dynamic cruise
control, you are alerted by an audible signal
and the display of the message "Driving aid
functions fault".
Have the system checked by a CITROËN
dealer or a qualified workshop.

When the cruise control is working, take
care if making a maintained press on
one of the cruise control programmed
speed modification buttons: this can
lead to a very quick change in the
speed of your vehicle.
Do not use the dynamic cruise control
on slippery surfaces or in heavy traffic.
When descending a steep hill, the
cruise control may not be able to
prevent the vehicle from exceeding the
programmed speed.
When ascending a steep hill or when
towing, it might not be possible to attain
or maintain the programmed speed.

Operating fault

The operation of the radar, located in
the front bumper, may be disturbed by
accumulations of dirt (dust, mud, etc.)
or in certain weather conditions (snow,
ice, etc.).
The message "SYSTEM INACTIVE:
Visibility reduced" is displayed to signal
that the system has been put into
standby.
Clean the front bumper regularly.
When painting or touching up the
paint on the front bumper, consult
a CITROËN dealer or a qualified
workshop. Certain types of paint could
hinder the operation of the radar.

The use of mats not approved by
CITROËN may interfere with the
operation of the cruise control.
To avoid any risk of jamming the pedals:
- ensure that mats are secured

correctly,

- never fit one mat on top of another.

Dynamic cruise control with Stop function

The dynamic cruise control is a driving
aid that cannot in any circumstances
replace the observation of speed limits
and safe distances, nor the need for
vigilance on the part of the driver.
It is recommended that you always keep
your feet close to the pedals.
The driver must be ready to take back
control of their vehicle at any time,
using the brake or accelerator pedal as
appropriate.

This system provides two functions:
- automatic regulation of the speed of the

vehicle to a value programmed by the
driver,

- automatic adjustment of the distance

between your vehicle and the vehicle
ahead, even to the point of stopping your
vehicle completely.

It manages the acceleration and deceleration
of the vehicle by automatically acting on the
engine and the braking system.
To do this, the system has a radar, located in
the front bumper.

Principles

This system detects a vehicle running in front of
your vehicle, travelling in the same direction.
It automatically adapts the speed of your
vehicle to that of the vehicle in front, to maintain
a constant distance.
If the vehicle in front is running more slowly, the
system slows, or even stops your vehicle, using
engine braking and the braking system.
If the braking system is used to decelerate the
vehicle, the brake lamps come on.
If the vehicle in front accelerates or changes
lane, the cruise control progressively
accelerates your vehicle to return to the
programmed speed.
If the driver operates a direction indicator 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.
