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.

Driving on motor ways and fast roads is prohibited when towing. When towing a vehicle with all four wheels on the ground, always use an approved towing bar; rope and straps are prohibited. When towing a vehicle with the engine off, there is no longer any power
assistance for braking or steering.
In the following cases, you must always call on a professional recovery ser vice: - vehicle broken down on a motor way or fast road, - when it is not possible to put the gearbox into neutral, unlock the steering, or release the parking brake, - towing with only two wheels on the ground, - where there is no approved towing bar available...
