(Option/accessory.)

The BLIS1 function is designed to help provide assistance in heavy traffic with several lanes moving in the same direction by helping the driver to detect the presence of vehicles in the "blind spot" area behind and to the side of the vehicle.

BLIS Overview

Volvo XC90. BLIS Rapidly approaching vehicle zone

The system is designed to respond to:

  • Vehicles passing your vehicle.
  • Vehicles rapidly approaching your vehicle from behind.

When BLIS detects a vehicle in zone 1 or a rapidly approaching vehicle in zone 2, an indicator light will illuminate in the relevant rearview mirror and glow steadily. If the driver then uses the turn signal on the side in which the warning has been given, the indicator light will become brighter and begin flashing.

BLIS is active when your vehicle is traveling at a speed above 10 km/h.

If a passing vehicle's speed is more than 15 km/h faster than your vehicle, BLIS will not react.

  • 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 Owner's 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.
