Foot brake

The foot brake is part of the brake system.

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 not activated, greater pedal pressure is required to brake the car.

In very hilly terrain or when driving with a heavy load the brakes can be relieved by using engine braking in gearshift mode B.

Anti-lock braking system

The car has anti-lock brakes (ABS1), which prevents the wheels from locking while braking and allows maintained steering control.

After the car has been activated, a short test of the ABS system takes place. A further automatic test of the system may take place at low speed.

Light braking charges the hybrid battery

Energy is regenerated to the battery during light braking. The car's kinetic energy is then converted to electrical energy instead, which is used to charge the hybrid battery. Battery charging via regenerative braking is indicated in the driver display.

During heavier braking, braking is supplemented by the hydraulic brake system.

Symbols in the driver display

SymbolSpecification
P5P6-2037-iCup-Brake warning symbol
Check the brake fluid level. If the level is low, fill with brake fluid and check for the cause of the brake fluid loss.
P5P6-2037-iCup-Brake control symbol
Fault in pedal sensor.
P5P6-2037-iCup-ABS warning symbol

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.

P5P6-2037-iCup-Brake pedal symbol

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.
