6Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during 
phases when the vehicle is stationary (e.g.
  red 
lights, traffic jams). The engine automatically 
restarts - START mode - as soon as the driver 
indicates the intention of moving off again.
Primarily designed for urban use, the function 
is intended to reduce fuel consumption and 
exhaust emissions as well as the noise level 
when stationary.
The function does not affect the functionalities of 
the vehicle, in particular the braking.
Deactivation/Reactivation
By default, the function is activated when the 
ignition is switched on.
It is configured in the ADAS touch screen 
application.
or
Direct access to the Shortcuts for driving aids .
The display of a message on the instrument 
panel confirms the change of state.
If the function is deactivated while the engine is 
in STOP mode, it will restart immediately.

 or M, with 
the brake pedal depressed until the vehicle 
stops.
–
 
With the gear selector in mode  N
, with the 
vehicle stationary.
Time counter
A time counter adds up the time spent in standby 
during the journey. It is reset to zero every time 
the ignition is switched on.
Special cases:
The engine will not go into standby if the 
conditions for operation are not met and in the 
following cases:
–
 
Steep slope (ascending or descending).
–

conditions for operation are met again and in the 
following case:
– 
Automatic gearbox in mode  N
, vehicle speed 
exceeds 0.6 mph (1 km/h).
In this case, this indicator lamp flashes for 
a few seconds, then goes off.
Malfunctions
In the event of a fault with the system, this 
warning lamp flashes for a few moments 
on the instrument panel, then remains on, 
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a 
qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come 
on if there is a fault.
►
 
Switch off the ignition then start the engine 
again with the " ST
ART/STOP" button.
12 V battery
The Stop & Start system requires a 
12 V battery of specific technology and 
specification.
All work must be carried out only by a 
CITROËN dealer or a qualified workshop
Tyre under-inflation  detection
This system alerts the driver when one or more 
tyres have a drop in pressure.
The alert is raised when the vehicle is moving, 
not when stationary.
It compares the information given by the wheel 
speed sensors with  reference values, which 
must be reinitialised every time the tyre 
pressures are adjusted or a wheel changed.
It takes the last values 
  
stored during 
the
  reinitialisation   request into account. It is 
therefore essential that the tyre pressure is 
correct during the operation. This operation is 
the driver’s responsibility.
The tyre under-inflation detection cannot,  in any circumstances, replace the need 
for vigilance on the part of the driver.
This system does not avoid the need to 
regularly check the tyre pressures (including 
the spare wheel), especially before a long 
journey.
Driving with under-inflated tyres, particularly 
in adverse conditions (heavy load, high 
speed, long journey):
–
 
worsens road-holding.
–
 
lengthens braking distances.
–
 
causes premature wear of the tyres.
–
 
increases energy consumption.
The inflation pressures defined for the  vehicle can be found on the tyre pressure 
label.
For more information on the  Identification 
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly 
when the tyres are "cold" (vehicle stopped for 
1 hour or after a journey of less than 6 miles 
(10
 
km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures 
shown on the label.   
Page 103 of 228

Driving
6Snow chains
The system does not have to be 
reinitialised after fitting or removing snow 
chains.
Under-inflation alert
This is signalled by the fixed illumination  of this warning lamp, accompanied by an 
audible signal and, depending on equipment, the 
display of a message.
►
 
Reduce speed immediately
 , avoid excessive 
steering movements and avoid sudden braking.
►
 
Stop the vehicle as soon as it is safe to do 
so.
The loss of pressure detected may not  always cause visible deformation of the 
tyre.
Do not rely on just a visual check.
►
 
Using a compressor
 , such as the one in 
the temporary puncture repair kit, check the 
pressures of all four tyres when cold.
►
 
If it is not possible to carry out this check 
immediately
, drive carefully at reduced speed.
►
 
In the event of a puncture, use the 
temporary puncture repair kit or the spare wheel 
(depending on equipment).
Driving too slowly may not ensure 
optimum monitoring.
The alert is not immediately triggered in the 
event of a sudden loss of pressure or tyre 
blow-out. This is because analysis of the 
values read by the wheel's speed sensors 
can take several minutes.
The alert may be delayed at speeds below 
25 mph (40 km/h), or when adopting a sporty 
driving mode.
The alert is kept active until the system is  reinitialised.
Reinitialisation
► The system must be reinitialised after any 
adjustment to the pressure of one or more tyres, 
and after changing one or more wheels.
Before reinitialising the system, make 
sure that the pressures of the four tyres 
are correct for the conditions of use of the 
vehicle and conform to the values written on 
the tyre pressure label.
Check the pressures of the four tyres before 
performing the reinitialisation.
The system does not advise if a pressure is 
incorrect at the time of reinitialisation.
With the vehicle stationary, the system 
can be reinitialised in the 
Settings>Vehicle touch screen application.
►
 
Then select 
 Safety>Under-inflation 
reinitialisation .
►
 
Press 
 YES to confirm.
The
 
reinitialisation   is confirmed by the display of 
a message and an audible signal.
Malfunction
In the event of a malfunction, 
these warning lamps light up on 
the instrument panel.
A message appears, accompanied by an audible 
signal.
In this case, the tyre under-inflation monitoring 
function is no longer performed.
Have it checked by a CITROËN dealer or a 
qualified workshop.
"Space-saver" type spare wheel
The use of this type of spare wheel may 
suspend tyre pressure monitoring.
In this case, the malfunction warning lamp 
comes on and disappears once the wheel 
has been replaced by one of uniform size (the 
same as the others), the pressure readjusted 
and the
  reinitialisation   carried out.
Driving and manoeuvring 
aids - General 
recommendations
Driving and manoeuvring aids cannot, in 
any circumstances, replace the need for 
vigilance on the part of the driver.
The driver must comply with the Highway 
Code, must remain in control of the vehicle in 
all circumstances and must be able to retake 
control of it at all times. The driver must adapt    
Page 104 of 228
102
Driving
the speed to climatic conditions, traffic and 
the state of the road.
It is the driver's responsibility to constantly 
monitor traffic conditions, assess the distance 
and relative speed of other vehicles, and 
anticipate their manoeuvres before using the 
direction indicator and changing lanes.
These systems do not make it possible to 
exceed the laws of physics.
Driving aids
You should hold the steering wheel with 
both hands, always use the door and interior 
mirrors, always leave your feet close to the 
pedals and take a break every 2 hours.
Manoeuvring aids
The driver must always check the 
surroundings of the vehicle before and during 
the whole manoeuvre, in particular using the 
mirrors.
Radar(s)
The operation of the radar(s), along with 
any associated functions, may be affected 
by the accumulation of dirt (e.g.
  mud, ice), 
in poor weather conditions (e.g.
  heavy rain, 
snow), or if the bumpers are damaged.
If the front bumper is to be repainted, contact 
a CITROËN dealer or a qualified workshop; 
certain types of paint could interfere with the 
operation of the radar(s).
 
 
Driving aids camera
This camera and its associated functions 
may be impaired or not work if the windscreen 
area in front of the camera is dirty, misty, 
frosty, covered with snow, damaged or 
masked by a sticker.
In humid and cold weather, demist the 
windscreen regularly.
Poor visibility (inadequate street lighting, 
heavy rain, thick fog, snowfall), dazzle 
(headlamps of an oncoming vehicle, low sun, 
reflections on a damp road, leaving a tunnel, 
alternating shade and light) can also impair 
detection performance.
In the event of a windscreen replacement, 
contact a CITROËN dealer or a qualified 
workshop to recalibrate the camera; 
otherwise, the operation of the associated 
driving aids may be disrupted.
Other cameras
The images from the camera(s) 
displayed on the touch screen or on the 
instrument panel may be distorted by the 
terrain.
In the presence of areas in shade, or in 
conditions of bright sunlight or inadequate 
lighting, the image may be darkened and with 
lower contrast.
Obstacles may appear further away than they 
actually are.
Sensors
The operation of the sensors, as well as 
any associated functions, may be disrupted 
by noise pollution such as that emitted by 
noisy vehicles and machinery (e.g. lorries, 
pneumatic drills), by the accumulation of 
snow or dead leaves on the road or in the 
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible 
signal (long beep) indicates that the sensors 
may be dirty.
A front or rear impact to the vehicle can 
upset the sensors’ settings, which is not 
always detected by the system: distance 
measurements may be distorted.
The sensors do not systematically detect 
obstacles that are too low (pavements, studs) 
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind 
spots may not be detected or may no longer 
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound 
waves: pedestrians may not be detected.

6Maintenance
Clean the bumpers and door mirrors and 
the field of vision of the cameras regularly.
When washing your vehicle at high pressure, 
direct the spray from at least 30
  cm away 
from the radar, sensors and cameras.
Mats / Pedals covers
The use of mats or pedals covers not 
approved by CITROËN may interfere with 
the operation of the speed limiter or cruise 
control.
T
o avoid any risk of jamming the pedals:
–
 
Ensure that the mat is secured correctly
 .
–
 
Never fit one mat on top of another
 .
Units of speed
Ensure that the units of speed displayed 
in the instrument panel (mph or km/h) are 
those for the country you are driving in.
If this is not the case, when the vehicle is 
stationary, set the display to the required 
units of speed so that it complies with what is 
authorised locally.
In case of doubt, contact a CITROËN dealer 
or a qualified workshop.
Steering wheel with 
hands-on detection
(with Highway Driver Assist 2.0)
For more information, refer to the 
General recommendations on the use 
of driving and manoeuvring aids .
The steering wheel is equipped with a hands-on 
detection system to avoid distraction on the part 
of the driver.
It is prohibited to cover or attach anything to the 
steering wheel.
The driver must always check the  surroundings of the vehicle and 
supervise the whole manoeuvre.
Any use of a system built into
  Highway Driver 
Assist 2.0
  must remain under the driver’s 
vigilance.
The system also detects the presence of 
hands when using the Lane Positioning assist 
system with Highway Driver Assist.
The system may suffer interference or  not work correctly if:
–
 
the steering wheel is covered by some 
protection.
–
 
the driver wears thick gloves (e.g.
   ski 
gloves).
In the event of improper detection of hands on 
the steering wheel, Highway Driver Assist 2.0 
is not activated or is deactivated after a few 
seconds.
Installation of mechanical anti-theft 
devices on the steering wheel is 
prohibited - risk of damage!
Shortcuts for driving aids
Driving aids can be accessed directly to quickly 
activate/deactivate them.
By default, driving aids are already stored in the 
system (e.g. Stop & Start,
 
Active lane departure 
warning system).
Other driving aids can be added or deleted from 
the page.
It is configured in the ADAS>Functions 
touch screen application.
► Press the button corresponding to the 
driving assistance concerned: 
•

Navigation mapping should be regularly 
updated in order to receive accurate 
speed limit information from the system.
The units for the speed limit (mph or  km/h) depend on the country you are 
driving in.
This should be taken into account to ensure 
you observe the speed limit.
For the system to work properly when 
changing countries, the speed unit of the 
instrument panel must match that of the 
country you are driving in.
Automatic sign reading is a driving aid  system and does not always display the 
correct speed limits.
The speed limit signs present on the road 
always take priority over those displayed by 
the system. 
The system is designed to detect signs that 
conform to the Vienna Convention on road 
signs.
Specific speed limits, such as those for 
heavy goods vehicles, are not displayed.
The display of the speed limit on the 
instrument panel is updated when passing 
a speed limit sign intended for cars (light 
vehicles).
Activation/Deactivation
By default, the system is automatically activated 
at every engine start.
It is configured in the ADAS touch screen 
application.

The system may not display the speed limit if it 
does not detect a speed limit sign within a preset 
period and in the following situations:
–
 
Road signs that are obstructed, non-standard, 
damaged or bent.
–
 
Obsolete or incorrect maps.
Speed setting 
recommendations
The driver can select the speed displayed by the 
Road signs recognition  function as the speed 
setting for the speed limiter, cruise control or 
adaptive cruise control using the
 
OK
   button.
In the event of rain detection, the system offers 
the driver a speed setting lower than the speed 
read/from the map in order to adapt to weather 
conditions (e.g.
  on motorways, the proposed 
speed is 68 mph (110 km/h) instead of 81 mph 
(130 km/h).
Speed setting advance recommendations
With Highway Driver Assist 2.0 activated, 
the system detects the next speed limit sign, 
displays it in the background and proposes this 
new speed as the speed setting.
Once memorised:
–
 
If the speed setting is lower than the previous 
one, the vehicle slows down to reach this new 
speed when it gets to the sign.
–
 
If the speed setting is higher than the previous 
one, the vehicle speeds up to reach this new 
speed when it passes the sign.

When exceeding the speed is not due to the 
driver's action (e.g.
  in case of a steep slope), an 
audible signal is triggered immediately.
On a steep descent or in the event of 
sharp acceleration, the speed limiter will 
not be able to prevent the vehicle from 
exceeding the speed setting.
If necessary, apply the brakes to control your 
vehicle’s speed.
When the vehicle speed returns to the speed 
setting level, the speed limiter operates again: 
the speed setting display becomes fixed again.
