2021 Polestar 1 Steering Assistance During Collision Risks Owners Manual

Activate or deactivate the function using this button in the center display’s Function view.

Illuminated button indicator light – the function is activated.
Extinguished button indicator light – the function is deactivated.

The function is automatically activated each time the engine is started. (On some markets, the setting that was active when the engine was switched off is reactivated.)

NOTE
When the function is deactivated, the driver cannot receive steering assistance:

during risk of run-off.
during collision risks from oncoming traffic.

Although it is possible to deactivate the function, the driver is advised to keep it activated since it can help improve driving safety in most cases.

This function has two activation levels for intervention:

Steering assistance only
Steering assistance with braking

Steering assistance only

Intervention with steering assistance

Steering assistance with braking

Intervention with steering assistance and braking

Braking intervention assists in situations where steering assistance alone is not sufficient. Braking force is automatically adapted according to the situation at the moment the vehicle begins to run off the road.
The function is active at speeds between 65-140 km/h (40-87 mph) on roads with clearly visible traffic lane markings/lines.
The system uses a camera to monitor the edges of the road and the painted side marker lines. If the vehicle is about to cross the edge of the road, the function will attempt to steer the vehicle back onto the road. If this is not sufficient to keep the vehicle on the road, the brakes will also be applied.
However, the function will not provide either steering assistance or braking if the turn signal is used. The function will also not be activated if it detects that the driver is actively operating the vehicle.

Steering assistance at risk of collision

The Collision avoidance function can help the driver reduce the risk of the vehicle leaving its lane unintentionally and/or colliding with another vehicle or obstacle by actively steering the vehicle back into its lane and/or swerving.

The function consists of these sub-functions:

Run-Off Mitigation with steering assistance
Steering assistance during collision risks from oncoming traffic

After the system has automatically intervened, this text message will appear in the instrument panel:
Collision avoidance– Automatic intervention

WARNING

The function is supplementary driver support intended to facilitate driving and help make it safer – it cannot handle all situations in all traffic, weather, and road conditions.
The driver is advised to read all sections in the Manual about this function to learn of its limitations, which the driver must be aware of before using the function.
Driver support functions are not a substitute for the driver’s attention and judgment. The driver is always responsible for ensuring the vehicle is driven in a safe manner, at the appropriate speed, at an appropriate distance from other vehicles, and in accordance with current traffic rules and regulations.

NOTE
It is always the driver who must decide how much the vehicle should be in control – the vehicle can never take command.

Steering assistance during collision risks from oncoming traffic

Steering assistance has several sub-functions. Steering assistance during collision risks from oncoming traffic can help a distracted driver who has not noticed that the vehicle is veering out of the lane.

The function provides assistance by swerving your vehicle back into your own lane.

Oncoming vehicles
Own vehicle

When steering assistance is activated, a collision warning for driver support will also be activated. However, the brake pedal pulsations that are part of the collision warning will not be activated.

The function is active at speeds between 60-140 km/h (37-87 mph) on roads with clearly visible traffic lane markings/lines
If your vehicle is starting to veer from your own lane and a vehicle is approaching from the opposite direction, this function can help the driver steer the vehicle back into its own lane.
However, the function will not provide steering assistance if the turn signal is used. The function will also not be activated if it detects that the driver is actively operating the vehicle.

Steering assistance during collision risks limitations

The function may have limited functionality in certain situations and not intervene, e.g.:

for smaller vehicles such as motorcycles
if more than half of your vehicle has moved into the adjacent lane
on roads/lanes with indistinct or no side lane markings
outside the speed range 60-140 km/h (37-87 mph)
when speed-dependent power steering wheel resistance is working at reduced power – e.g. during cooling due to overheating.

Functionality may also be reduced in other situations, such as:

road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility.

In these demanding driving conditions, the function may not be able to properly assist the driver. In these situations, it is recommended that it is turned off.

NOTE
The function uses the vehicle’s camera and/or radar units, which have certain general limitations.

Symbols and messages for steering assistance during collision risks

A number of symbols and messages related to steering assistance may be displayed in the instrument panel. Several examples are provided below.

Symbol	Message	Meaning
	Collision avoidance Automatic intervention	When the function is activated, a message will appear to alert the driver.
