2022 Volvo S90 Recharge Plug-in Hybrid Rear Collision Warning
Rear Collision Warning
The Rear Collision Warning (The function is not available in all markets.)(RCW) function can help the driver to avoid being hit by a vehicle approaching from behind.
Drivers in vehicles behind can be warned about an imminent collision by the function flashing intensively with the direction indicators.
If, at a speed below 30 km/h (20 mph), the function detects that the car is in danger of being hit from behind, the seatbelt tensioners may tension the front seatbelts. The Whiplash Protection System is also activated in the event of a collision.
Immediately before a collision from behind, this function may also activate the foot brake in order to reduce the forward acceleration of the car during the collision. However, the foot brake is only activated if the car is stationary. The foot brake releases immediately if the accelerator pedal is depressed.
This function is activated automatically each time the engine is started.
Warning
- The function is supplementary driver support intended to facilitate driving and 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 Owner’s Manual that relate to this function to learn about factors such as its limitations and what the driver should be aware of before using the system.
- Driver support functions are not a substitute for the driver’s attention and judgement. The driver is always responsible for ensuring the car 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.
Limitations of Rear Collision Warning
In certain cases, the Rear Collision Warning (RCW) (Rear collision warning.)may have difficulty helping the driver in the event of a collision risk.
This can, for example, be if:
- the vehicle approaching from behind is detected too late
- the vehicle approaching from behind changes lane at the last moment
- a trailer, bicycle rack or similar is connected to the car’s electrical system – the function is then deactivated automatically.
