On a car equipped with Four-C the shock absorption is adapted according to the drive mode selected and the speed of the car. Shock absorption is normally set for optimum comfort and is regulated continuously depending on the road surface, the car’s acceleration, braking and cornering.
Polestar Engineered variant cars have the option to adjust the shock absorbers manually. There are three recommended positions: performance position, dynamic position, and comfort position.
The performance position means that the car’s shock absorption feels harder.
Dynamic position is the car’s factory setting that is adapted for daily driving.
Comfort position means that the car’s shock absorption feels softer.
During parking
- During parking, make sure you allow adequate space above and below the car since the car’s ground clearance may vary e.g. depending on the outside temperature, how the car is loaded or the use of loading mode.
The level may also be adjusted some time after the car has been parked. This is to compensate for any changes in height that may occur due to temperature changes in the air springs when the car cools down.
Symbols and messages
If a fault arises with the level control, a message is shown in the driver display.
Symbol | Message | Specification |
---|---|---|
| Suspension Deactivated by user | The active self-levelling has been switched off manually by the user. |
| Suspension Temporarily reduced performance | The performance of the active self-levelling has been temporarily reduced due to extensive system use. |
| Suspension Service required | A fault has occurred. Visit a workshop as soon as possible. |
| Stop safely Suspension failure | A critical fault has occurred. The car’s driving performance is significantly reduced, stop safely. Have the car transported (raised with all wheels on the flat-bed) to a workshop if the message is shown when the car is stationary. |
| Slow down Suspension Car too high | A fault has occurred. The car’s driving performance is reduced, slow down until the symbol disappears. Contact a workshop if the message is shown when the car is stationary. |
| Suspension Auto adjusting car level | Level control of the car’s rear axle to target height in progress. |
Adjusting the setting for shock absorptionPolestar Engineered
There are four adjuster knobs, two for the front shock absorbers and two for the rear. The adjuster knobs are located above each wheel. For the front wheels, the adjuster knobs are located under the bonnet. For the rear wheels, the adjuster knobs are located above each wheel in the wheel housing.
Location of adjuster knob, front wheel.
Make sure that the adjuster knob is set to 0 position before starting the adjustment. This way it is easier to know which adjustment position is set.
Turn the adjuster knob clockwise and anticlockwise respectively to change adjustment position.
- Turn the control clockwise until it has stopped in order to access adjustment position 0.
- Turn the control anticlockwise to select the desired adjustment position. Adjustment positions are defined with an audible and noticeable click.
Then carry out the same procedure for the other shock absorber.
Adjusting the setting for shock absorption, rear
The rear adjuster knobs are located above the tyre inside the wheel housing. The car must be raised on a jack to access the rear adjuster knobs, see separate section.
The rubber cover is located above the adjuster knob.
Turn the adjuster knob clockwise and anticlockwise respectively to change adjustment position.
- Remove the protective rubber cover that covers the adjuster knob.
- Turn the control clockwise until it has stopped in order to access adjustment position 0.
- Turn the adjuster knob anticlockwise to select the desired adjustment position. Adjustment positions are defined with an audible and noticeable click.
When the desired position has been set, refit the protective rubber cover. Then carry out the same procedure for the other shock absorber.
To achieve as good performance as possible, Volvo recommends that the adjuster knobs are set at the same position for each axle.
Position | Front | Rear |
Performance position | adjustment position 4 | adjustment position 4 |
Dynamic position | adjustment position 10 | adjustment position 10 |
Comfort position | adjustment position 15 | adjustment position 15 |
Volvo only takes responsibility for the recommended adjustment positions.
