Volvo XC90: Driver support / BLIS
(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.

Location of BLIS indicator light
BLIS is a driver support system designed to alert the driver of:
- vehicles in your "blind spot"
- vehicles approaching rapidly in adjacent lanes.

BLIS overview
Blind spot zone
Rapidly approaching vehicle zone
The system is designed to react to:
- vehicles passing your vehicle
- vehicles that are 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 over 10 km/h (6 mph).
If a passing vehicle's speed is more than 15 km/h (9 mph) faster than your vehicle,
BLIS will not react.
NOTE
The light illuminates on the side of the vehicle where the system has detected
the vehicle. If the vehicle is passed on both sides simultaneously, both lights
come on.
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 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.
