Blind spot sensors


This driving assistance system warns the driver
of the presence of another vehicle in the blind
spot angle of their vehicle (areas masked from
the driver's field of vision), as soon as this presents a potential danger.

Operation


This 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 asses the distances and relative speeds of other vehicles and to predict their movements before deciding whether to change lane.
The blind spot sensor system can never replace the vigilance and responsibility of the driver.

)
On switching on the ignition, or engine
running, press this button to activate the
function; the warning lamp comes on.
Sensors fitted in the front and rear bumpers
monitor the blind spots. A warnin
g lamp appears in the door mirror on
the side in question:
- immediatel
y, when being overtaken,
- after a delay of about one second, when
over taking a vehicle slowly.

217Driving
Operating fault
In the event of a fault, the warning lamp in the
button flashes then goes off.
Have it checked by a CITROËN dealer or aqualified workshop.

The system may suffer temporary interference in certain weather conditions (rain, hail...).
In par ticular, driving on a wet surfaceor moving from a dry area to a wet area can cause false alerts (for example,the presence of a fog of water droplets in the blind spot angle is interpreted as a vehicle). In bad or wintry weather, ensure thatthe sensors are not covered by mud, ice or snow. Take care not to cover the warningzone in the door mirrors or thedetection zones on the front and rear bumpers with adhesive labels or other objects; they may hamper the correct operation of the system.
)To deactivate the system, press this buttonagain; the warning lamp goes off.
The state of the system remains in memory on switching off the ignition.

The system is automaticallydeactivated when towing with a towbar approved by CITROËN.

Parking space sensors


System which measures the parking space available between two vehicles or obstacles.
It measures the size of the space and gives you
information on:


- the possibility of fitting into a free space,
depending on the dimensions of your
vehicle and the distances needed for manoeuvring,

- the level of difficulty of the manoeuvre to
be performed.
The s
ystem does not measure spaces which
are clearl
y much smaller or larger than the sizeof the vehicle.
Displays in the instrument panel You have identified a parking space:)
Press button A
to select the function.)
Operate the direction indicator on the side where the space is to be measured;
a message is displayed to confirm thatmeasurement is in progress.) During measurement, go forward the
length of the space, at a speed less than
12 mph (approx. 20 km/h), to prepare for your manoeuvre.) Once the measurement has beencompleted, the system informs you of
the level of difficulty of the manoeuvre
by a message in the multifunction screen
accompanied by an audible signal.


Operation

The parking space sensor function
warning lamp can have two differentstates:
-
on fixed:the function is selected by a
press on control A . -
off:
the function is not selected,

The function displays the following types of message: The function deselects itself automatically:


- when you engage reverse gear,

- when you switch off the ignition,

- if measuring is not requested,

- within five minutes of selection of the function,

- if the vehicle speed exceeds the
threshold of 45 mph
(approx. 70 km/h) for one minute.

If the lateral distance between
your vehicle and
the parking space is too large, the system maynot be able to measure the space.
The s
ystem remains available after each measurement and can therefore measure several spaces in succession.
In poor or wintry weather, ensure that the sensors are free of dir t, ice or snow.
The parking space sensor system deactivates
the front parking sensors when measuring
forwards.
Parking possible
Parking difficult
Parking not advised
If there is a fault, have the system checked by a CITROËN dealer or a qualified workshop.

Driving





Parking sensors

This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.) which comes within the field of detection of sensorslocated in the bumper.
Cer tain types of obstacle (stake, roadworkscone, etc.) detected initially will no longer bedetected at the end of the manoeuvre due to
the presence of blind spots.


This function cannot, in any
circumstances, take the place of the vigilance and responsibility of the driver.The s
ystem is switched on by engaging reversegear. This is accompanied by an audible signal.
The system is switched off when you exit reverse gear.
Rear parking sensors
Audible assistance
The proximity information is given by anintermittent audible signal, the frequency of whichincreases as the vehicle approaches the obstacle.
The sound emitted by the speaker (right or left)indicates the side on which the obstacle is located. When the distance between the vehicle andthe obstacle becomes less than approximately
thirty centimetres, the audible signal becomescontinuous.



Visual assistance

This supplements the audible signal by
displaying bars in the multifunction screen
which move progressively nearer to the vehicle.
When the obstacle is near, the "Danger" symbol is also displayed in the screen.

Front par king sensors
Operating fault

In the event of a malfunction of
the system, when reverse gear is engaged this warning lamp
is displa
yed in the instrument panel and/or a message appears in the screen, accompanied
by an audible signal (short beep).
Contact a CITROËN dealer or a qualified
workshop. In addition to the rear parkin
g sensors, the front parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle
is still 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 fur ther obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).
The function will be deactivated automatically if a trailer is being towed or a bicycle carrier is fitted (vehicle fitted with a towbar or bicycle carrier recommended by CITROËN).


In bad weather or in winter, ensure that the sensors are not covered with mud, ice or snow. When reverse gear isengaged, an audible signal (long beep)indicates that the sensors may be dirty.
When the vehicle is moving at a speed
below 6 mph (10 km/h), cer tain soundsources (motorcycle, lorry, pneumatic drill, etc.) may trigger the audiblesignals of the parking sensor system.



Deactivation/Activation of the front and rear parking sensors

The function is deactivated by pressing this button.The indicator lamp in the button comes on.
Pressing this button again reactivates the function. The indicator lamp in the button goes off.


The sound emitted by the speaker (front or rear) indicates whether theobstacle is in front or behind.

The spare wheel is installed in the boot under
the floor.Depending on version, the spare wheel may bea standard size steel or alloy wheel, or for some countries it is the "space saver" type.
For access to the spare wheel, refer to theparagraph "Access to the tools" on the previouspage.
Access to the spare wheel
Tyre under-infl ation detection

Ta k i ng out the standard wheel
)Unscrew the yellow central bolt. )Raise the spare wheel towards you from
the rear.)Take the wheel out of the boot.

Changing the side spotlamps
For the replacement of this type of LED lamp,contact a CITROËN dealer or a qualified
workshop.


Changing the LED lamps/sidelamps

For the replacement of this type of LED lamp, contact a CITROËN dealer or a qualified
workshop.
Changing foglamp bulbs
)Introduce a flat screwdriver in the hole in
the finisher. )Pull and lever to unclip the bumper finisher (the parking sensor stays with the finisher).)Remove the two module fixing screws and remove it from its housing. )Disconnect the bulb holder connector. )Turn the bulb holder a quarter of a turn andextract it. )Pull the bulb and change it.
To r e f i t , c a r ry out these operations in reverse order.
To replace these bulbs you may also contact a
CITROËN dealer or a qualified workshop.

The rear parking sensors will be deactivated automatically if a genuine CITROËN towbar is used.

Driving advice
Distribution of loads
)Distribute the load in the trailer so that theheaviest items are as close as possible to
the axle and the nose weight approaches the maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing engine per formance. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towed loads which apply to your vehicle.
Side wind
)Take into account the increased sensitivity
to side wind.

Cooling

Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling capacity is not dependent on the engine speed.)
To lower the engine speed, reduce your speed.
The maximum towed load on a long inclinedepends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.

Braking

To w i ng a trailer increases the braking distance.
To a v o i d o v e r h e a t i ng of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.


Tyres
)Check the tyre pressures of the towing
vehicle and of the trailer, obser ving the recommended pressures.



Lighting
)Check the electrical lighting and signalling on the trailer.
)If the warning lamp and the
STOP warning lamp come on, stop the vehicle and switch off
t
he engine as soon as possible.
