pg. 73 Brake system
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.
Brake circuit malfunction
The brake system is a hydraulic system consisting of two master cylinders and two separate brake
circuits. If a problem should occur in one of these circuits, it is still possible to stop the car with the other
brake circuit.
If the brake pedal must be depressed farther than normal and requires greater foot pressure, the stopping
distance will be longer.
A warning light in the instrument panel will light up to warn the driver that a fault has occurred.
If this light comes on while driving or braking, stop immediately and check the brake fluid level in the
reservoir.
NOTE: Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes.
WARNING!
If the fluid level is below the MIN mark in either section of the reservoir: DO NOT DRIVE. Have the
car towed to a Volvo retailer and have the brake system checked and any leakage repaired.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Never let
the vehicle roll to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed approximately four times harder
