2012 Citroen DS4 parking sensors

227Driving
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 thefunction,
- 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 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.

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, 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 b
y the speaker (right or left)
in
dicates the side on which the obstacle is located.
When the distance between the vehicle and
the obstacle becomes less than approximatelythirty centimetres, the audible signal becomes continuous.



Visual assistance

This supplements the audible signal bydisplaying 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.

Driving
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
b
y 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 towedor 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 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 theobstacle is in front or behind.

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.
