Braking system

Your vehicles most important safety feature, the braking system, is provided by brake discs (or discs and drums) and a dual hydraulic circuit. When the engine is running, power assistance is provided so that pedal effort is reduced. On wet roads, or after washing the vehicle, there can be a slight delay in brake response. From time to time, apply the brakes briefly so that the heat generated can dispel any moisture.

ABS - Anti-lock Braking System

This system improves vehicle safety by preventing the wheels from locking under

This system improves vehicle safety by preventing the wheels from locking under emergency braking or when braking on surfaces offering poor adhesion. It thus allows control of the steering to be retained. The operational capacity of the various electrical components of the ABS is continuously monitored, both before and during your journey. On switching on the ignition, the ABS warning lamp will light up and then should go out after a few seconds.

If the warning lamp stays on, this means that the ABS has been disconnected because a fault was detected. If the warning lamp lights up when you are driving, this means that the ABS system is not active.

In either case, the normal braking system remains effective, as on a vehicle without ABS. Nevertheless, to restore the additional safety afforded by correct functioning of ABS, it is recommended that the vehicle be taken to a CITROËN dealer as soon as possible. On slippery roads (loose stones, snow, ice, etc.), it remains essential to drive with caution.

If the parking brake is off, the lighting of this warning lamp, in conjunction

If the parking brake is off, the lighting of this warning lamp, in conjunction with the STOP warning lamp, indicates that the brake fluid level is low or that the braking distributor is malfunctioning.

It is essential to stop the vehicle.

Contact a CITROËN dealer as soon as possible.

Emergency braking assistance

This system enables you in an emergency to achieve the optimum braking pressure, thus to reduce the stopping distance. It is triggered by your speed of action on the brake pedal, which reduces its resistance to that action. Keep the brake pedal pressed until the vehicle comes to a stop. In the event of emergency braking, press and keep the pedal down very firmly without reducing the level of effort.

When the engine is not running, the braking system will not have powerassistance. The effort required on the brake pedal will be considerably increased. Take all reasonable safety precautions if you have to move the vehicle. Never drive the vehicle without the engine running.
