Anti-lock brakes (ABS) If the warning lamp lights up there is a malfunction of the ABS system 138 06 Starting and driving Brake system (the standard braking system will however function) and the vehicle should be driven cautiously to a trained and qualified Volvo service technician for inspection. The Anti-lock Braking System (ABS) helps to improve vehicle control (stopping and steering) during severe braking conditions by limiting brake lockup. When the system "senses" impending lockup, braking pressure is automatically modulated in order to help prevent lockup, which could lead to a skid. The system performs a self-diagnostic test when the engine is started and when the vehicle first reaches a speed of approximately 12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible from the ABS control module. This is normal. To obtain optimal effect from the ABS system, constant pressure should be kept on the brake pedal. Do not pump the brake pedal. The switching of the ABS modulator will be audible and the brake pedal will pulsate during braking. 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. ABS with EBD (Electronic Brake Force Distribution) EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide optimal braking capacity. The brake pedal will pulsate during braking, which is normal. If the BRAKE and ABS warning lights come on at the same time, this could indicate a fault in the brake system. 1. Stop the vehicle in a suitable place and switch off the engine. 2. Restart the engine. 3. If both warning lights go off, no further action is required. 4. If both lights are still on after the engine has been restarted, switch off the engine again and check the brake fluid level (see page 196 for the location of the brake fluid reservoir). WARNING If the fluid level is below the MIN mark in the reservoir or if a "Brake failure - Service urgent" message is displayed in the text window: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the brake system inspected. 5. If the brake fluid level is above the MIN mark, drive carefully to a trained and qualified Volvo service technician and have the brake system inspected. Emergency Brake Assistance (EBA)

The system performs a self-diagnostic test when the engine is started and when the vehicle first reaches a speed

that ABS does not increase the absolute braking potential of the vehicle. While control will be enhanced, ABS will not

ABS with EBD (Electronic Brake Force Distribution)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide
optimal braking capacity. The brake pedal will pulsate during braking, which is normal.
If the BRAKE and ABS warning lights come on at the same time, this could indicate a fault in the brake system.
1. Stop the vehicle in a suitable place and switch off the engine.
2. Restart the engine.
3. If both warning lights go off, no further action is required.
4. If both lights are still on after the engine has been restarted, switch off the engine again and check the brake fluid
level (see
page 196
for the location of the brake fluid reservoir).
WARNING
If the fluid level is below the MIN mark in the reservoir or if a "Brake failure - Service urgent" message is displayed
in the text window: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician
and have the brake system inspected.
5. If the brake fluid level is above the MIN mark, drive carefully to a trained and qualified Volvo service technician
and have the brake system inspected.
