Anti-lock Brake System (ABS)

If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will
however function) and the vehicle should be driven cautiously to a Volvo retailer for inspection. The
Anti-lock Braking System (ABS) helps to improve vehicle control (stopping and steering) during severe
braking conditions by limiting brake lock-up. When the system "senses" impending lock-up, braking
pressure is automatically modulated in order to help prevent lock-up, which could lead to a skid.
The system performs a self-diagnostic test when the vehicle first reaches a speed of approximately
4 mph (6 km/h).
To obtain optimal effect from the ABS system, constant pressure should be kept on the brake
pedal while the system is modulating the brakes. Do not pump the brake pedal.
The switching of the ABS modulator will be audible and the brake pedal will pulsate at this time. Please
be aware that ABS does not increase the absolute braking potential of the vehicle. While control will be
enhanced, ABS will not shorten stopping distances on slippery surfaces.
