Volvo XC90: Driver support / Steering assistance during collision risks from behind
(Option/accessory.)
Steering assistance has several sub-functions. If you become distracted and
do not notice your vehicle starting to veer out of the lane while another vehicle
is approaching from behind or is in your vehicle's blind spot, Steering assistance
during collision risks from behind can help provide assistance.

The function provides assistance by steering your vehicle back
into your own lane.

Own vehicle
If your vehicle is beginning to veer out of your lane while another vehicle is
in your blind spot or another vehicle is rapidly approaching in the next lane, this
function can help the driver steer the vehicle back into its own lane.
Even if the driver intentionally changes lanes using a turn signal without noticing
another vehicle approaching, the function can provide assistance.
The function is active at speeds between 60-140 km/h (37-87 mph) on roads with
clearly visible traffic lane markings/lines.
The lights in the door mirrors will flash while steering assistance is being
provided, whether or not the BLIS1 function is activated. An audible
signal will also sound.
