Auto-hold brakes

With the auto-hold brake function (Hold), the driver can release the brake pedal and the brakes will remain applied, for example, when the vehicle has stopped at a traffic light.

Activating HoldDepress the brake pedal when the vehicle is stationary to activate Hold. The function is always available while driving and works at any gradient.

To activate Hold, make sure that

  • the driver’s seat belt is buckled and/or the driver’s door is closed
  • gear selector position D or R is selected.

Deactivating HoldThe function is released when the driver presses the accelerator pedal with a gear position selected.

NOTE

The hold is also deactivated when the driver moves the gear selector to the neutral position.

The parking brake is applied automatically

  • if the driver removes their seat belt and/or opens the driver’s door.
  • if the function has been active for longer than 10 minutes.

Brake fluid specifications

The medium in the hydraulic brake system is called brake fluid and is used to transfer braking force from e.g. pressure on the brake pedal via a master brake cylinder to one or more slave cylinders, which in turn act on a mechanical brake.

Recommended grade: Brake fluid meeting a combination of Dot 45.1, and ISO 4925 class 6.

NOTE

Changing or filling brake fluid should be entrusted to an authorized workshop.

Brake functions

The vehicle’s brakes are used to reduce speed or prevent the vehicle from rolling.
In addition to the wheel brakes and parking brakes, the vehicle is also equipped with a number of automatic brake assist functions. These systems help the driver by e.g. keeping the vehicle stationary when the brake pedal is not depressed (e.g. at a traffic light or intersection) or when starting up a hill.
Depending on how the vehicle is equipped, the following brake assist functions may be included:
  • Auto-hold brakes
  • Braking assist after a collision
  • Creep – the vehicle is kept stationary, depending on the setting
  • Warning and auto-braking while backing up
  • Assistance during collision risks

Braking assist after a collision

In a collision in which the activation level is reached for the pyrotechnic seat belt tensioners or airbags, or if a collision with a large animal is detected, the vehicle’s brakes will be automatically activated. This function is intended to help prevent or reduce the effects of any subsequent collision.
After a serious collision, it may no longer be possible to control and steer the vehicle. In order to avoid or mitigate a possible further collision with a vehicle or an object in the vehicle’s path, the brake assist system is activated automatically to help stop the vehicle safely.
The brake lights and hazard warning flashers are activated during braking. When the vehicle has stopped, the hazard warning flashers will continue to flash and the parking brake will be applied.
If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the driver can override the system by depressing the accelerator pedal.
This function assumes that the brake system is intact after a collision.

One Pedal Drive

There are three different levels of One Pedal Drive, which indicate the regenerative braking effect that is controlled by the accelerator pedal, without the use of the brake pedal.
The vehicle’s factory default setting is Standard mode. Adapts braking effect to the driving situation in which the vehicle is used, e.g. snowy or icy roads.

Setting in the center display

  • Tap.
  • Select Drive.
  • Adjust braking effect preferences under One Pedal Drive.
Position Braking effect
Off No braking power will be applied and the vehicle will roll freely.
Low Some braking effect will be applied.
Standard High braking effect.
NOTE

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

Regenerative braking

The vehicle uses braking energy and regenerates current to the battery when the driver releases the accelerator pedal or when the brake pedal is used.

NOTE

The vehicle’s regenerative ability may be reduced on slippery or icy roads.

Regeneration using the accelerator pedal

  • Release the accelerator pedal.

> The vehicle brakes with the selected braking effect and charging are indicated in the instrument panel.

NOTE

If braking power exceeds a certain level, the brake light will go on.

Regeneration using the brake pedal

  • Depress the brake pedal
