Foot brake
The car is equipped with two brake circuits. If a brake circuit is damaged, the brake pedal may engage deeper. Higher pressure on the pedal will therefore be needed to produce the normal braking effect.
If the foot brake is used when the car is switched off, the brake pedal needs to be depressed passed the normal braking position using a higher pressure to brake the car.
Anti-lock braking system
The car has anti-lock brakes (ABS1), which prevents the wheels from locking while braking and allows maintained steering control. Vibration may be felt in the brake pedal when this is engaged and this is normal.
A short test of the ABS system is made automatically after the car has been started when the driver releases the brake pedal. A further automatic test of the system may be made at low speed. The test may be felt as pulses in the brake pedal.
Symbols in the driver display
| Symbol | Specification |
|---|---|
 | Check the brake fluid level. If the level is low, fill with brake fluid and check for the cause of the brake fluid loss. |
 | Fault in pedal sensor. |
 | Constant glow for 2 seconds when the car is started: Automatic function check. Constant glow for more than 2 seconds: ABS fault. The car's regular brake system continues to work, but without ABS function. |
 | In the event of the message:Brake pedal characteristics changed Service required The brake pedal needs to be depressed past the normal braking position using a higher pressure to brake the car. |
Warning
If both the warning lamps for brake fault and ABS fault illuminate at the same time, a fault has occurred in the brake system.
- If the level in the brake fluid reservoir is normal at this stage, drive carefully to the nearest workshop and have the brake system checked - an authorised Volvo workshop is recommended.
- If the brake fluid is below the MIN level in the brake fluid reservoir, do not drive further before topping up the brake fluid. The reason for the loss of brake fluid must be investigated.
