Blind Spot Detection
This system warns the driver of the presence
of another vehicle in the blind spots of their
vehicle (areas hidden from the driver's field
of vision), as soon as this presents a potential
danger.
A fixed warning lamp appears in the door mirror
on the side in question:
-
i

mmediately, when being overtaken,
-

a
fter a delay of about one second, when
overtaking a
vehicle slowly. This driving aid system is designed to
improve safety when driving and is in no
circumstances a
substitute for the use
of the interior rear view mirror and door
mirrors. It is the driver's responsibility to
constantly check the traffic, to assess the
relative distances and speeds of other
vehicles and to predict their movements
before deciding whether to change lane.
This system is a driving aid that cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
Activation/Deactivation
The function is activated and
deactivated in the Driving menu of
the touch screen.
When the function is activated,
this indicator lamp comes on in the
instrument panel.
The state of the system stays in memory when
switching off the ignition.
The system is automatically deactivated
when towing with a
towing device
approved by CITROËN.
Operation
Sensors fitted in the front and rear bumpers
monitor the blind spots.
The alert is given by an orange warning lamp
coming on in the relevant door mirror, as soon
as a
vehicle – car, lorry, cycle – is detected.
The following conditions must be met for this:
-

a
ll vehicles are moving in the same direction
and in adjacent lanes,
-

t
he speed of the vehicle must be between
7
and 87 mph (12 and 140 km/h),
-

y
ou overtake a vehicle with a speed
difference of less than 6
mph (10 km/h),
-

a v
ehicle overtakes you with a speed
difference of less than 16
mph (25 km/h),
-

t
he traffic is flowing normally,
-

ov
ertaking a vehicle over a certain period
of time and the vehicle being overtaken
remains in the blind spot,
-

y
ou are driving on a straight or slightly
curved road,
-

y
our vehicle is not pulling a trailer, a
caravan, etc.

Active Blind Spot
Monitoring System
(depending on version)
In addition to the fixed warning lamp in the door
mirror on the side in question, a correction of
trajectory will be felt if you cross a lane marking
with the direction indicators on, to help you
avoid a


collision.
Conditions for operation
The following systems must be activated:
- B lind Spot Detection,
-
L

ane Departure Warning System.
The speed of the vehicle must be between
40
and 87 mph (65 and 140 km/h) inclusive.
Fatigue detection system
Take a break as soon as you feel tired or at
l east every two hours.
Depending on version, the function relies either
on the "Driver Attention Warning" system alone
or combined with the "Driver Attention Alert"
system.
These systems cannot in any circumstances
replace the need for vigilance on the part
of the driver who must remain in control
of their decisions. In no case can these
systems keep the driver awake or prevent
them from falling asleep at the wheel.
It is the driver's responsibility to stop if they
feel tired.
Activation/Deactivation
These functions are activated and
deactivated in the Driving menu of
the touch screen.
The state of the system stays in the memory
when the ignition is switched off.
Driver Attention Warning
The system triggers an alert once it
detects that the driver has not taken
a
break after two hours of driving at
a
speed above 40 mph (65 km/h).This alert is issued via the display of
a
message encouraging you to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the
alert is repeated hourly until the vehicle is
stopped.
The system resets itself if one of the following
conditions is met:
-
e
ngine running, the vehicle has been
stationary for more than 15

minutes,
-
t
he ignition has been switched off for a few
minutes,
-
t
he driver's seat belt is unfastened and their
door is open.
As soon as the speed of the vehicle drops
below 40 mph (65 km/h), the system goes
into standby.
The driving time is counted again once the
speed is above 40 mph (65 km/h).
Driver Attention Alert
Depending on version, the "Driver Attention
Warning" may be combined with the "Driver
Attention Alert".

Driving

177
This function is a manoeuvring aid which
c annot, in any circumstances, replace the
need for vigilance on the part of the driver.
The driver must remain attentive and stay
in control of their vehicle.
They must always check the vehicle's
surroundings before undertaking
a


manoeuvre.
During the entire manoeuvre, the driver
must ensure that the space remains clear.
Rear parking sensors
The system is switched on by engaging reverse
g e a r.
This is confirmed by an audible signal.
The system is switched off when you come out
of reverse gear.
Audible assistance
The information on proximity is given by an
intermittent sound signal, the succession of
which becomes more rapid as the vehicle
approaches the obstacle.
The sound emitted by the speaker (right or left)
indicates which side the obstacle is on.
When the distance between the vehicle and
the obstacle becomes less than approximately
thirty centimetres, the audible signal becomes
continuous.
Visual assistance
It supplements the audible signal by displaying
bars on the screen that move progressively
nearer to the vehicle (white: more distant
obstacles; orange: close obstacles; red: very
close obstacles).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
In addition to the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of
the vehicle remains below 6
mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6
mph (10 km/h).
The sound emitted by the speaker (front or
rear) indicates whether the obstacle is in
front or behind.
Deactivation/Activation
The function is deactivated and
activated in the Driving menu of the
touch screen.
This warning lamp comes on in the

Fuel
Fuel tank capacity: approximately 57 litres
(petrol) or 55 litres (Diesel).
Low fuel level
When the low fuel level is reached,
this warning lamp in the instrument
panel comes on, accompanied by
an audible warning, a message and
the last bar of the fuel gauge lights
up orange.
When it first comes on there remains
approximately 6


litres of fuel in the tank.
Until sufficient fuel has been added, this
warning lamp appears every time the ignition
is switched on, accompanied by an audible
warning and a
message. This audible warning
and this message are repeated with increasing
frequency as the fuel level drops towards " 0".
Refuel as soon as possible to avoid running
out.
Refilling
A self-adhesive label on the inner face of the
filler flap reminds you of the type of fuel to use,
depending on your engine.

this could cause malfunctions.
Your vehicle is fitted with a
catalytic converter,
a device which helps to reduce the level of
harmful emissions in the exhaust gases.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, allowing only
unleaded petrol nozzles to be introduced.
If you have put in the wrong fuel for
your vehicle, you must have the fuel
tank drained and filled with the correct
fuel before star ting the engine.
Fuel cut- of f
Your vehicle is fitted with a safety system that
c uts off the supply of fuel in the event of an
impact.
Opening the filler flap may create a

noise
caused by an inrush of air. This is entirely
normal and results from the sealing of the fuel
system. F

Brake fluid level
The fluid level should be close to the
"MA X" mark. If it is not, check the
brake pad wear.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
The check and top-up must only be done with
the engine cold.
A low coolant level presents a
risk of serious
damage to your engine.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up. To avoid the risk of scalding when you need to
top up in an emergency, wrap a
cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the
cap and top up to the required level.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
