Manual release
Before leaving the vehicle, check that parking brake warning lamp in the instrument panel is on fixed, not flashing.
Manual application
With the vehicle stationary, to apply the parking brake whether the engine is running or off, pullcontrol lever A .
The application of the parking brake is confirmed by:
- illumination of the braking warning lamp and of the P warning lamp in the control lever A ,
- display of the message "Handbrake on".
When the driver’s door is opened with the engine running, a message is displayed accompanied by an audible signal if the parking brake has not been applied.
The full application of the parking brake is confirmed by:
- the braking warning lamp and the P warning lamp in the control lever A going off,
- display of the message "Handbrake off ".
If you pull control lever A without pressing the brake pedal, the parking brake will not be released and a warning lamp will come on in the instrument panel.
Maximum application
If necessary, you can make a maximum application of the parking brake. This is obtained by means of a long pull on the control lever A , until you see the message "Handbrake on maximum" and a beep is heard. Maximum application is essential: - in the case of a vehicle towing a caravan or a trailer, if the automatic functions are activated but you are applying the parking brake manually, - when the gradient you are parked on may vary (e.g. on a ferry, on a lorry, during towing),
In the case of towing, a loaded vehicle or parking on a gradient, make a maximum application of the parking brake then turn the front wheels towards the pavement and engage a gear when you park. After a maximum application, the release time will be longer.

With the vehicle stationary, the parking brake is automatically applied when the engine is switched off.

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 cer tain weather conditions(rain, hail...). In par ticular, driving on a wet sur face or moving from a dry area to a wet area can cause false aler ts (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 with adhesive labels or other objects. Do not stick labels or attach objects to
the front and rear bumpers; 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.

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.

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.

Electric parking brake
This system does not require any routine ser vicing. However, in the event of a problem, have the system checked by a CITROËN dealer or a qualified workshop. For more information, see "Driving - Electric parking brake - § Operating faults".
Only use products recommended by CITROËN or products of equivalent quality and specification. In order to optimise the operation of units as impor tant as the braking system, CITROËN selects and offers very specific products. To avoid damaging the electrical units, the use of a high pressure washer in the engine compar tment is strictly prohibited . Brake disc wear
For information on checking brake disc wear, contact a CITROËN dealer or a qualified workshop.
Manual parking brake
If a loss of effectiveness of this system is noticed, the parking brake must be checked, even between two ser vices. Checking this system must be done by a CITROËN dealer or a qualified workshop.
Brake pads
Brake wear depends on the style of driving, par ticularly in the case of vehicles used in town, over shor t distances. It may be necessary to have the condition of the brakes checked, even between vehicle ser vices. Unless there is a leak in the system, a drop in the brake fluid level indicates that the brake pads are worn.
