2001 VOLVO C70
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
If one of the brake circuits should malfunction, the red warning light will come on, the pedal stroke
increases slightly, the pedal feels softer and extra pressure is required for normal braking. If the light
comes on while driving or braking, stop immediately and check the brake fluid level in the reservoir.
WARNING!
If the fluid level is below the MIN mark in either section of the reservoir: DO NOT DRIVE. Tow the
car to a Volvo retailer and have the brake system checked and any leakage repaired.
Moisture on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect on the
brake discs and pads. This will cause a delay in braking effect when the pedal is depressed. To avoid
such a delay when the brakes are needed, depress the pedal occasionally when driving through rain,
slush etc. This will remove the water from the brakes. Check that brake application feels normal. This
should also be done after washing or starting in very damp or cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or hilly areas or towing. The speed
is usually low which means that the cooling of the brakes is less efficient than when driving on level
roads. To reduce the strain on the brakes, it is advisable not to use the brakes excessively. Instead, shift
into a lower gear, position 3 or in some cases, L (automatic transmission) and let the engine help with
the braking. Do not forget that, if you are towing a trailer, the brakes will be subjected to greater load
than is normal.
If the brake powerassist does not function
The power assist to the brakes functions only when the engine is running. When the car is moving
