Under-inflation alert


The loss of pressure detected does
not always lead to visible deformation
of the tyre. Do not rely on just a visual
check.

This alert is also displayed when one or
more wheels is not fitted with a sensor.

The alert is maintained until the tyre
or tyres concerned is reinflated or
repaired.

The aler t is given by the fixed illumination
of this warning lamp, accompanied by
an audible signal, and depending on
equipment, the display of a message.
In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.


Reduce speed, avoid sudden steering
movements or harsh brake applications.


Stop as soon as it is safe to do so.


In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (according to equipment),
or


if you have a compressor, the one in the
temporary puncture repair kit for example,
check the four tyre pressures when cold,
or


if it is not possible to check the tyre
pressures at the time, drive carefully at
reduced speed.


Operating fault

The flashing and then fixed illumination
of the under-inflation warning lamp
accompanied by the illumination of the
"ser vice" warning lamp indicates a fault
with the system.
In this case, monitoring of the tyre pressures is
not assured.
Have the system checked by a CITROËN
dealer or a qualified workshop.

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 warning lamp appears in the door mirror on
the side in question:


- immediately, when being overtaken,

- after a delay of about one second, when
overtaking a vehicle slowly.

221Driving

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 a
qualified workshop.
The system may suffer temporary
inter ference in certain weather
conditions (rain, hail...).
In particular, driving on a wet sur face
or 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 that
the sensors are not covered by mud,
ice or snow.
Take care not to cover the warning
zone in the door mirrors or the
detection 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 button
again; the warning lamp goes off.
The state of the system remains in memory on
switching off the ignition.
The system is automatically
deactivated when towing with a towbar
approved by CITROËN.

227Driving





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 system does not measure spaces which
are clearly much smaller or larger than the size
of 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 that
measurement is in progress.


During measurement, go for ward 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 been
completed, 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 different
states:


- 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 may
not be able to measure the space.
The system 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 dirt, 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.

229Driving





Parking sensors

This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.)
which comes within the field of detection of
sensors located in the bumper.
Certain types of obstacle (stake, roadworks
cone, etc.) detected initially will no longer be
detected 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 system is switched on by engaging reverse
gear. 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 an
intermittent audible signal, the frequency of which
increases 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 and
the obstacle becomes less than approximately
thirty centimetres, the audible signal becomes
continuous.




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 displayed in the screen.

Front parking sensors
Operating fault

In the event of a malfunction of
the system, when reverse gear
is engaged this warning lamp
is displayed 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 parking 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 further 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 is
engaged, an audible signal (long beep)
indicates that the sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals 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 the
obstacle is in front or behind.

The spare wheel is installed in the boot under
the floor.
Depending on version, the spare wheel may be
a standard size steel or alloy wheel, or for some
countries it is the "space saver" type.
For access to the spare wheel, refer to the
paragraph "Access to the tools" on the previous
page.

Access to the spare wheel


Ty r e u n d e r - i nfl ation detection

The spare wheel is not fitted with a
sensor. The punctured wheel must
be repaired by a CITROËN dealer or
aqualified workshop.



Taking 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.

If your vehicle has an electric parking
brake, only a space saver wheel can be
stowed in the boot.

Driving advice


Distribution of loads




Distribute the load in the trailer so that the
heaviest 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 by 10 % for every 1 000 metres of
altitude.


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 incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.



If the warning lamp and the STOP

warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.

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



Braking

Towing a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.


Ty r e s




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.

Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
