2021 Polestar 1 Adaptive Cruise Control
Adaptive Cruise Control(Depending on market, this function can be either standard or optional.)
The camera/radar sensor measures the distance to the vehicle ahead.
Adaptive Cruise Control can help provide a more relaxed driving experience on long trips on highways or long, straight roads with even traffic flows.
The driver sets a speed and a time interval to the vehicle ahead. If the camera/radar sensor detects a slower-moving vehicle ahead, your vehicle’s speed will be automatically adapted according to the set time interval to that vehicle. When there are no longer slower-moving vehicles ahead, the vehicle will return to the set speed.
Adaptive Cruise Control regulates speed by accelerating and braking. It is normal for the brakes to emit a slight sound when they are being used to adjust speed.
Adaptive Cruise Control attempts to:
- smoothly regulate speed. The driver must apply the brakes in situations requiring immediate braking. For example, when there are great differences in speed between vehicles or if the vehicle ahead brakes suddenly. Due to limitations in the radar sensor, braking may occur unexpectedly or not at all.
- follow a vehicle ahead in the same lane and maintain a time interval to that vehicle set by the driver. If the radar sensor does not detect a vehicle ahead, it will instead maintain the speed set by the driver. This will also happen if the speed of the vehicle ahead exceeds the set speed for your vehicle.
- 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, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
Only a workshop may perform maintenance on driver support components – contact Polestar Customer Support.
- Optional/accessory – The equipment described in the Manual is not available in all cars – the cars have different equipment depending on adaptations for the needs of different markets and national or local laws and regulations.

Time interval
Adaptive Cruise Control will only regulate the time interval to the vehicle ahead when the distance symbol shows two vehicles. A speed interval will be marked at the same time.
When driving
In the following illustration, Road Sign Information (RSI)(Road Sign Information) indicates that the maximum permitted speed is 130 km/h (80 mph).
The previous illustration shows that Adaptive Cruise Control is set to maintain a speed of 110 km/h (68 mph) and that there is no target vehicle ahead to follow.
The previous illustration shows that Adaptive Cruise Control is set to maintain a speed of 110 km/h (68 mph) and is following a target vehicle ahead, which is traveling at the same speed.
Adaptive Cruise Control limitations
(Depending on the market, this function can be either standard or optional.)
Steep roads and/or heavy loads
Adaptive Cruise Control is primarily intended to be driven on flat roads. The function may not be able to maintain the correct time interval to the vehicle ahead when driving down steep hills. The driver should be extra attentive and prepared to apply the brakes.
Do not use Adaptive Cruise Control if the vehicle is carrying a heavy load.
- This is not a collision-avoidance system. The driver is always responsible and must intervene if the system fails to detect a vehicle ahead.
- The function does not brake for people or animals and does not brake for small vehicles, such as bikes and motorcycles. Similarly, it does not brake for low trailers, oncoming, slow-moving or stationary vehicles, and objects.
- Do not use the function in demanding situations, such as in city traffic, at intersections, on slippery surfaces, with a lot of water or slush on the road, in heavy rain/snow, in poor visibility, on winding roads, or on/off ramps.
The function uses the vehicle’s camera and/or radar units, which have certain general limitations.
Adaptive Cruise Control standby mode
(Depending on market, this function can be either standard or optional)
Standby mode means that the function is selected in the instrument panel but not activated. In standby mode, Adaptive Cruise Control will not regulate speed or distance to the vehicle ahead.
Standby mode due to action by the driver
Adaptive Cruise Control will be deactivated and put in standby mode if any of the following occurs:
- The brakes are applied.
- The gear selector is moved to N.
- The vehicle is driven faster than the set speed for more than 1 minute.
Temporarily increasing speed using the accelerator pedal, e.g. when passing another vehicle, will not affect the setting. The vehicle will return to the set speed when the accelerator pedal is released.
- If Adaptive Cruise Control is in standby mode, the driver must intervene and regulate both speed and distance to the vehicle ahead.
- If the vehicle comes too close to a vehicle ahead when Adaptive Cruise Control is in standby mode, the driver can be warned of the short distance by the Distance Alert* function.
Automatic standby mode
With automatic standby mode, the driver is warned by an acoustic signal and a message on the instrument panel.
- The driver must then regulate vehicle speed, apply the brakes if necessary, and maintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standby mode if:
- Any of the systems that Adaptive Cruise Control is dependent on stops working, e.g. stability control/anti-skid (ESC).(Electronic Stability Control)
- The driver opens the door.
- The driver unbuckles the seat belt.
- The engine speed (rpm) is too low/high.
- One or more of the wheels lose traction.
- The brake temperature is high.
- The parking brake is applied.
- The camera/radar sensor is covered by snow or heavy rain (the camera lens/radar waves are blocked).
- Your vehicle’s speed goes under 5 km/h (3 mph) and ACC cannot determine if the object ahead is a stationary vehicle or if it is another object, e.g. a speed bump.
- Your vehicle’s speed goes under 5 km/h (3 mph) and the vehicle ahead turns so that ACC no longer has a vehicle to follow.
Adjusting set speed for driver support
| : Increases the set speed |
|
| : Reduces the set speed |
|
| Set speed |
-
Change a set speed by pressing the
(1) or (2) buttons briefly or by pressing and holding them:- Brief press: Each press changes the speed in +/- 5 km/h (+/- 5 mph) increments.
- Press and hold: Release the button when the set speed indicator (3) has moved to the desired speed.
> The most recently set speed will be stored.
For vehicles without Adaptive Cruise Control*, speed instead increases by +/- 1km/h (+/- 1 mph) each time the button is pressed.
Using the accelerator pedal
If speed is increased by depressing the accelerator pedal while pressing the (1) button on the steering wheel, the vehicle’s speed when the button is pressed will be stored as the set speed.
Temporarily increasing speed using the accelerator pedal, e.g. when passing another vehicle, will not affect the setting. The vehicle will return to the set speed when the accelerator pedal is released.
Possible speed
The lowest speed that can be set is 30 km/h (20 mph). When following another vehicle, ACC can monitor that vehicle’s speed and slow your own vehicle down to a standstill, but it is not possible to set speeds lower than 30 km/h (20 mph).
The driver support functions can follow another vehicle at speeds from a standstill up to 200 km/h (125 mph).
Pilot Assist can provide steering assistance from near-stationary speeds up to 140 km/h (87 mph).
Auto-hold braking with driver support
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stopped at a traffic light, driving will resume automatically if the vehicle is stopped for less than approx. 3 seconds. If it takes more than 3 seconds for the vehicle ahead to begin moving again, the driver support function will go into standby mode and the auto-hold brake function will activate.
-
The function can be reactivated by:
- Pressing the button on the steering wheel keypad.
- Pressing the accelerator pedal.
- Pressing the
> The function will resume following the vehicle ahead if it begins to move within approx. 6 seconds.
A noticeable increase in speed may follow when the speed is resumed with the steering wheel button.
The driver support system only issues a warning for obstacles detected by its camera and radar units, which means that warnings may come after a delay or not at all.
- Never wait for a warning or assistance. Apply the brakes when necessary.
Driver support can keep the vehicle stationary for no more than 5 minutes – after that time the parking brake is applied and the function is deactivated.
The parking brake must be released before driver support can be reactivated.
This can occur if:
- The driver depresses the brake pedal.
- The parking brake is applied.
- The gear selector is moved to the P, N or R positions.
- The driver puts Adaptive Cruise Control or Pilot Assist in standby mode.
The parking brake is applied if the function is keeping the vehicle stationary using the brakes and:
- The driver opens the door or unbuckles his/her seat belt.
- The function has kept the vehicle at a standstill for more than approx. 5 minutes.
- The brakes overheat.
- The driver switches off the engine.
Collision risk warning from the driver support
- Collision warning audible signal and symbol
- Collision warning audible signal
- Collision warning symbol
Adaptive Cruise Control and Pilot Assist use approx. 40% of the braking capacity. If a situation requires more braking force than driver support can provide, and if the driver does not apply the brakes, a warning light and audible warning signal will be activated to alert the driver that immediate action is required.
The driver support system only issues a warning for vehicles detected by its radar unit – thus, a warning may come after a delay or not at all. Never wait for a warning. Apply the brakes when necessary.
Visual warnings on the windshield may be difficult to notice in cases of strong sunlight, reflections, extreme light contrasts, or if the driver is wearing sunglasses or is not looking straight ahead.
Deactivating Adaptive Cruise Control
(Depending on market, this function can be either standard or optional)
- Press the button on the steering wheel (2).
> The symbol and indicators are extinguished – Adaptive Cruise Control is set in standby mode. The time interval indicator light and any symbols for the target vehicle will go out.
-
Press the
(1) or 
(3) buttons on the steering wheel to select another function.
> The Adaptive Cruise Control symbol and marking (4) in the instrument panel will go out and the set/stored maximum speed will be erased.
- If Adaptive Cruise Control is in standby mode, the driver must intervene and regulate both speed and distance to the vehicle ahead.
- If the vehicle comes too close to a vehicle ahead when Adaptive Cruise Control is in standby mode, the driver can be warned of the short distance by the Distance Alert* function.
- Optional/accessory – The equipment described in the Manual is not available in all cars – the cars have different equipment depending on adaptations for the needs of different markets and national or local laws and regulations.
Selecting and activating Adaptive Cruise Control
(Depending on market, this function can be either standard or optional.)
To start the function:
- The driver’s seat belt must be buckled and the driver’s door must be closed.
- There must be a vehicle ahead (target vehicle) within a reasonable distance or your vehicle’s current speed must be at least 15 km/h (9 mph).
-
Press the ◀ (1) or ▶ (3) button on the steering wheel keypad and scroll to the Adaptive Cruise Control symbol
(4).
> Gray symbol – Adaptive Cruise Control is in standby mode.
- When Speed Limiter is selected, press (2) on the steering wheel keypad to activate.
> White symbol – Speed Limiter starts and the current speed is stored as the maximum speed.
- When Adaptive Cruise Control is selected, press on the steering wheel keypad to activate.
> The Cruise Control marking in the instrument panel will change from GRAY to WHITE and the vehicle will then return to the most recently set speed.
A noticeable increase in speed may follow when the speed is resumed with the steering wheel button.
Setting time intervals to the vehicle ahead
Different time intervals to the vehicle ahead can be selected and are shown in the instrument panel as 1–5 horizontal bars. The more bars, the longer the time interval. One bar represents an interval of approx. 1 second to the vehicle ahead. 5 bars represents approx. 3 seconds.
When the symbol in the instrument panel shows a vehicle and a steering wheel, Pilot Assist is following a vehicle ahead at a preset time interval.
When only a steering wheel is shown, there is no vehicle ahead within a reasonable distance.
When the symbol in the instrument panel shows two vehicles, the Adaptive Cruise Control is following the vehicle ahead at a preset time interval.
When only one vehicle is shown, there is no vehicle ahead within a reasonable distance.
- Controls for setting a time interval.
- Reduce the time interval
- Increase the time interval
- Press the (1) or (2) button to decrease or increase the time interval.
> The distance indicator (3) shows the current time interval.
In order to help your vehicle follow the vehicle ahead as smoothly and comfortably as possible, Adaptive Cruise Control allows the time interval to vary noticeably in certain situations. At low speeds, when the distance to the vehicle ahead is short, Adaptive Cruise Control increases the time interval slightly.
- The greater the vehicles’ speed, the greater the distance between them for a set time interval.
- Only use the time intervals permitted by local traffic regulations.
- If driver support does not seem to respond with a speed increase when activated, it may be because the time interval to the vehicle ahead is shorter than the set time interval.
- Only use a time interval suitable for the current traffic conditions.
- The driver should be aware that short time intervals give them limited time to react and act to any unforeseen traffic situation.
Switching between cruise control and Adaptive Cruise Control in the center display
Activate or deactivate the function using this button in the center display’s Function view.
- Illuminated button indicator light – Adaptive Cruise Control is deactivated and the regular cruise control is in standby mode.
- Extinguished button indicator light – regular cruise control is deactivated and the Adaptive Cruise Control is in standby mode.

Switching target vehicles with driver support
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When driver support is actively following another vehicle at speeds under 30 km/h (20 mph) and switches targets from a moving vehicle to a stationary vehicle, driver support will brake for the stationary vehicle.
When driver support follows another vehicle at speeds over approx. 30 km/h (20 mph) and changes target vehicle – from a moving vehicle to a stationary one – driver support will ignore the stationary vehicle and instead accelerate to the stored speed.
- The driver must then intervene and apply the brakes.
Driver support disengages and goes into standby mode if:
- your vehicle’s speed goes under 5 km/h (3 mph) and driver support cannot determine if the target is a stationary vehicle or if it is another object, e.g. a speed bump.
- your vehicle’s speed goes under 5 km/h (3 mph) and the vehicle ahead turns so that driver support no longer has a vehicle to follow.
