2010.5 Citroen DS4 DAG Owner's Manual

Cruise control
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal.
The functions of this system are grouped together on the steering mounted controls. 1. Cruise control mode selection dial. 2. Speed programming/value decrease button. 3. Speed programming/value increase button. 4. Cruise control off/resume button. 5. Stored speeds display button. (see "Storing speeds")
Steering mounted controls
The cruise control system cannot, in any circumstances, replace the need to respect speed limits, nor can it replace the need for vigilance and responsibility on the par t of the driver. You are advised to keep your feet near the pedals at all times.
The programmed information is grouped together in the instrument panel screen. 6. Cruise control off/resume indication. 7. Cruise control mode selection indication. 8. Programmed speed value. 9. Selecting a stored speed. (see "Storing speeds")
Displays in the instrument panel
Operation
The cruise control is switched on manually: it requires a minimum vehicle speed of 25 mph (40 km/h) and engagement of: - four th gear on the manual gearbox, - second gear on the electronic gearbox system, in sequential driving mode, - position A on the electronic gearbox system. The cruise control is switched off manually d offor by pressing the brake or clutch pedal or on triggering of the ESP system for safety reasons. It is possible to exceed the programmed speed temporarily by pressing the accelerator pedal. To return to the programmed speed, simply
release the accelerator pedal. Switching off the ignition cancels any programmed speed value.

217Driving
Programming
 Turn dial 1 to the "CRUISE" position: the cruise control mode is selected but is not switched on (Pause).  Set the programmed speed by accelerating
to the required speed, then press button 2 or 3 (e.g.: 70 mph (110 km/h)); the cruise control system is activated (ON).
You can then change the programmed speed using buttons 2 and 3 : - by + or - 1 mph (km/h) = shor t press, - in steps of + or - 5 mph (km/h) = maintained press. If storing speeds is available and activated on your vehicle, the programmed speed will stop at the closest stored sp eed; refer to the corresponding section.  Stop the cruise control system by pressing button 4 : this is confirmed in the screen (Pause).
 Switch on the cruise control again with another press on button 4 .
Exceeding the programmed speed
Intentional or unintentional exceeding of the programmed speed results in flashing of this speed in the screen. Return to the programmed speed, by means of intent ional or unintentional deceleration of the vehicle, automatically cancels the flashing of the speed.
Exiting cruise control mode
 Turn dial 1 to the "0" position: the cruise control mode is deselected. It disappears from the screen.
Operating fault
In the event of a cruise control malfunction, the speed is cleared resulting in flashing of the dashes. Have it checked by a CITROËN dealer or a
qualified workshop.
When the cruise control is switched on, be careful if you maintain the pressure on one of the programmed speed changing buttons: this may result in a very rapid change in the speed of your vehicle. Do not use the cruise control on slippery roads or in heavy traffic. On a steep descent, the cruise control will not be able to prevent the vehicle from exceeding the programmed speed. On steep climbs or when towing, the programmed speed may not be reached or maintained. To avoid any risk of jamming of the pedals: - ensure that the mat is positioned correctly,
- never fit one mat on top of another.

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 per formed. 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,

219Driving
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 dir t, ice or snow. The parking space sensor system deactivates the front parking sensors when measuring for wards.
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 sensors located 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 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 thir ty 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 also displayed in the screen.

221Driving
Front parking sensors Operating fault
If an operating fault occurs, 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 (shor t 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 sound emitted by the speaker (front or rear) indicates whether the obstacle is in front or behind. 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 is engaged, an audible signal (long beep) indicates that the sensors may be dir ty. When the vehicle is moving at a speed below 6 mph (10 km/h), cer tain 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.
