Driving

Principles of operation

Adaptive cruise control

When the cruise control is switched on, be

careful if you maintain the pressure on one

of the programmed speed modification

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.

When descending a steep hill, the cruise

control system cannot prevent the vehicle

from exceeding the programmed speed.

On steep climbs or when towing, the

programmed speed may not be reached

or maintained.

Using radar with a range of about 100 metres,

located at the front of the vehicle, this system

detects a vehicle travelling in front of your

vehicle.

It automatically adapts the speed of your

vehicle to that of the vehicle in front.

If the vehicle in front is travelling 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 the vehicle in

front or is approaching it too quickly, adaptive

cruise control is automatically deactivated.

The driver is then alerted by an audible signal

accompanied by a message.

The system allows the speed of

your vehicle to be maintained at the

setting you have made, and also to

respect the inter-vehicle time that

you have selected between your

vehicle and the one in front, when

the situation permits it.

Switching between the

types of cruise control

The use of mats not approved by

CITROËN may interfere with the operation

of the cruise control.

The choice between "adaptive" and "standard"

cruise control is made in the Driving menu.

To avoid any risk of jamming of the pedals:

If the vehicle in front accelerates or changes

lane, the adaptive cruise control gradually

accelerates your vehicle to return to the

programmed speed.

-

ensure that mats are secured correctly,

never fit one mat on top of another.

F

Turn the cruise control wheel to

the "CRUISE" position.

6

If the driver operates the direction indicator to

the left (left-hand drive) or to the right (right-

hand drive), to overtake a slower vehicle, the

adaptive cruise control allows your vehicle to

temporarily approach the vehicle in front to

assist the overtaking manoeuvre, though never

exceeding the programmed speed.

F In the Driving menu, select the Driving

functions tab and then Active cruise

control to activate or deactivate adaptive

cruise control.

For more information on the Cruise

control, refer to the corresponding

section.

The adaptive cruise control operates

by day and at night, in fog or moderate

rainfall.

151

Driving

The adaptive cruise control uses only

-

when the speed of the vehicle in front is too

low,

when the speed of your vehicle becomes

too low.

If the cruise speed setting is above

engine braking to slow the vehicle.

Consequently the vehicle loses speed

slowly, as when releasing the accelerator

pedal.

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 (19 mph (30 km/h)).

93 mph (150 km/h), the adaptive cruise

control switches to standard cruise control

mode, without automatic regulation of the

inter-vehicle safety distance (a message

appears in the instrument panel).

The inter-vehicle time setting is

memorised when switching off the ignition.

The adaptive cruise control cannot in any

circumstances replace the observation of

speed limits, nor the need for the vigilance

on the part of the driver.

It is recommended that you always keep

your feet close to the pedals.

Steering mounted control

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.

The adaptive cruise control can be paused

manually or automatically:

-

by pressing button 4,

by pressing the brake pedal,

if the ESC system is activated, for safety

reasons,

if there is an action on the electric parking

brake control,

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),

General information

The adaptive cruise control is switched on

radar and if the speed selected is much

higher than the speed of that vehicle,

the system does not activate and the

alert message "Activation not possible,

conditions unsuitable" is displayed until

the driving conditions are safe to allow

activation of the system.

The table below describes the alerts and

messages displayed depending on the driving

situation.

The display of these alerts is not sequential.

Exceeding the programmed

setting

It is possible to exceed the speed setting

temporarily by depressing the accelerator

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 observe the programmed inter-vehicle time.

The regulation range is limited to a maximum difference of 19 mph (30 km/h) between the

cruise speed setting and the speed of the vehicle in front.

"SPEED

ADJUSTED"

When the adjusted speed reaches the limit of regulation (speed setting – 19 mph

(30 km/h)), the adjusted speed flashes together with the speed setting to signal that

automatic deactivation of the system is imminent.

paused".

If the system exceeds the limit of speed adjustment that it can make and in the absence of

any reaction by the driver (operation of the direction indicator, change of lane, reduction in

the speed of the vehicle), the system is automatically paused.

The display of the deactivation message is accompanied by an audible signal.

enough to continue to maintain a safe

distance, for example when descending

a steep hill.

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.

The regulation range is limited to a maximum

difference of 19 mph (30 km/h) between the

cruise speed setting and the speed of the

vehicle in front. Above this, the system goes into

pause if the safety distance becomes too short.

-

vehicles not running in the middle of the

lane,

When the conditions allow, it is

recommended that the function 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 cruise control

using the old cruise speed setting, which

may be very different from the current

speed of your vehicle.

Poor weather conditions (very heavy

rain, accumulation of snow in front of the

radar) may hinder the operation of the

system, with the display of the operating

fault message "SYSTEM INACTIVE:

Reduced visibility". The function remains

unavailable until the message disappears.

-

vehicles entering a corner,

vehicles changing lane at the last moment.

The cruise control does not take account of:

-

stationary vehicles,

vehicles driving in the opposite direction.

Operating limits

Since the radar detection range is relatively

narrow, it is possible that the system cannot

detect:

The adaptive cruise control uses only engine

braking to slow the vehicle. Consequently the

vehicle loses speed slowly, as when releasing

the accelerator pedal.

Malfunction

In the event of a malfunction of the adaptive

cruise control system, you are warned 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.

The system is paused automatically:

-

if the vehicle in front slows down too much

or too suddenly, and the driver does not

brake,

-

vehicles of reduced width, such as

motorcycles, for example,

-

if a vehicle comes between your vehicle and

the vehicle in front.

156

Driving

This system provides the following

functions:

When the cruise control is working, take

care if keeping pressed one of the cruise

control programmed speed change

buttons: this can lead to a very rapid

change in the speed of your vehicle.

Do not use adaptive cruise control on

slippery surfaces or in heavy traffic.

When descending a steep hill, the cruise

control system cannot prevent the vehicle

from exceeding the programmed speed.

On steep climbs or when towing, the

programmed speed may not be reached

or maintained.

Operation of the radar, located in the

front bumper, may be impaired by the

accumulation of dirt (dust, mud, etc.) or in

certain weather conditions (snow, frost,

etc.).

The message "SYSTEM INACTIVE:

Reduced visibility". is displayed to indicate

that the function is in standby.

Clean the front bumper regularly.

If the front bumper is to be repainted or

retouched, contact a CITROËN dealer

or a qualified workshop. Certain types of

paint could interfere with the operation of

the radar.

-

Automatically maintains the

vehicle at the speed set by the

driver.

-

Automatic adjustment of the

distance between your vehicle

and the one in front.

With an automatic gearbox, automatic

adjustment of the distance can cause your

vehicle to come to a complete stop.

The use of mats not approved by

CITROËN may interfere with the operation

of the cruise control.

Cruise control remains active after

changing gear regardless of the gearbox

type.

To avoid any risk of jamming of the pedals:

-

ensure that mats are secured correctly,

never fit one mat on top of another.

Adaptive cruise control

until vehicle is stopped/

until 19 mph (30 km/h)

It manages the acceleration and deceleration

of the vehicle by automatically acting on the

engine and the braking system.

6

Function until vehicle is stopped: with

automatic gearbox

Function until 19 mph (30 km/h): with manual

gearbox

For this purpose there is a radar installed in the

front bumper.
