The driver should not leave the vehicle.
–


Do not open the boot.
–


Do not drop off or pick up passengers.
–


Do not engage reverse gear
.
When restarting the vehicle, beware of
cyclists, pedestrians or animals who are
not taken into account by the system.
The driver must monitor their surroundings.
Operating limits
Cruise control operates by day and night, in dry
weather or moderate rainfall.
Certain situations cannot be managed by the
system and require driver intervention.
Cases not taken into account by the system:
–

Pedestrians, cyclists, animals.
–


Stationary vehicles (e.g.
traffic jams,
breakdown).


– Vehicles crossing your lane.
– V ehicles driving in the opposite direction.
Situations where the driver must suspend the
system:


– Vehicles in a tight bend.
– When approaching a roundabout.

– When following a narrow vehicle.
Reactivate the system when conditions allow .
Situations in which the driver is prompted to
immediately resume control:
–

Excessively sharp deceleration by the vehicle
in front of you.

If the driver no longer wishes to use the system
for some time, they can deactivate it by pressing
the button again (confirmed when the symbol
disappears).
The system status is saved when the ignition is switched off.
Operating conditions
– Adaptive cruise control active.
– ESC system operational.
–

ASR system activated.
–


No trailer detected.
–


No 'space-saver' spare wheel in use.
–


V
ehicle not subject to strong lateral g-forces.
–

Direction indicators not activated.
Regulation
The driver must hold the steering wheel
properly.
When regulation is activated, the symbols are
displayed in green: with small steering inputs,
the system steers the vehicle and keeps it in the
position chosen by the driver in the traffic lane.
This position is not necessarily the centre of the
lane.
The driver can feel movements in the steering
wheel.
At any time, the driver can change the position of
the vehicle by intervening on the steering wheel
and maintaining the position until the system has
taken it into account. If the chosen position is too
off-centre, an automatic re-centering manoeuvre
can occur. The system adjusts to the newly
defined position.
Pausing/Suspending the
system
The driver must act promptly if they believe that the traffic conditions or the
state of the road surface require their
intervention, by moving the steering wheel to
temporarily suspend system operation. Any
action on the brake pedal that causes the
Adaptive cruise control
system to be paused
will also cause the system to be paused.
If the system detects that the driver is not
holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no response from
the driver.
If the function is suspended due to the
prolonged release of the force holding
the steering wheel, the system must be
reactivated by pressing the button again.
Automatic suspension
Suspension of the system is accompanied by a
specific audible signal.
–

T
riggering of the ESC system.
–

Insufficient lane detection. In this case, the
Lane keeping assist function can take over

,
and the system will reactivate itself once the
operating conditions are met again.
Paused by the driver
– Travelling outside the lane limits.
– T oo tight a grip on the steering wheel or
dynamic action on the steering wheel.
–

Action on the brake pedal (resulting in a pause
until cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal is
depressed).
–


Pausing of the
Adaptive cruise control system.
–

Deactivation of the
ASR system.

In the event of a breakdown
8After changing a wheel
With a "space-saver" type spare wheel
Deactivate certain driving aid functions
(Active Safety Brake, Adaptive cruise control,
etc.).
Do not exceed the maximum authorised
speed of 50 mph (80 km/h).
Driving with more than one "space-saver"
type spare wheel is prohibited.
Visit a CITROËN dealer or a qualified
workshop.
Have the tightening of the spare wheel's bolts
and its tyre pressure checked.
Have the punctured tyre examined. After
inspection, the technician will advise you on
whether the tyre can be repaired or if it must
be replaced.
Changing a bulb
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
Never look too closely at the light beam
of LED technology lamps - risk of serious
eye injury!


The headlamps have polycarbonate lenses with a protective coating:
–

Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
–


Use a sponge and soapy water or a pH
neutral product.
–


When using a high-pressure washer on
persistent marks, do not keep the lance
directed towards the headlamps, lamps or
their edges for too long, so as not to damage
their protective coating and seals.
Changing a bulb must only be done with
the ignition off and after the headlamp /
lamp has been switched off for several
minutes - risk of serious burns!
Do not touch the bulb directly with your
fingers; use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
Refitting the lamp units
Perform the operations in the reverse
order to dismantling.
