Foot brake

The foot brake is part of the brake system.


Never drive the car when the brake warning lamp is lit.

The car is equipped with two brake circuits. If a brake circuit is damaged, the brake pedal will engage deeper. Higher pressure on the pedal will therefore be needed to produce the normal braking effect.


The brake servo only works when the car is running.

If the foot brake is used when the car is not running, greater pedal pressure is required 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.

After the car has been started, 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 battery

Under light braking, the car's kinetic energy is converted into energy which is used to charge the battery. Battery charging is indicated in the driver display.

The driver display indicates charging.

During heavier braking, braking is supplemented by the hydraulic brake system. This is indicated in the driver display by orange on the far left of the brake gauge.

Polestar recommends regular hard braking with the friction brake to avoid problems with the brake discs caused by inactivity, such as rust or dirt accumulation.

Symbols in the driver display

PS2-2007-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.
PS2-2007-Brake control symbol
Fault in pedal sensor.
PS2-2007-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.

PS2-2007-Brake pedal symbol

In the event of the message: The characteristics of the brake pedal have changed. Service is required.

The brake pedal needs to be depressed past the normal braking position using a higher pressure to brake the car.


If both the warning lamps for brake fault and ABS fault illuminate at the same time, a fault may have occurred in the brake system.

  • If the level in the brake fluid reservoir is normal in this case – contact Polestar Customer Support.
  • 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.
