The BSA system monitors the
detection zone from three different
entry points (side, rear, overtaking
traffic) while driving to see if an alert
is necessary. The BSA system will issue
an alert whenever a vehicle enters any
one detection zone as outlined below.
Entering from the Side
Vehicles that move into your adjacent
lanes from either side of the vehicle.
Entering from the Rear
Vehicles that come up from behind
your vehicle on either side and enter
the rear detection zone with a relative
speed of less than 30 mph (48 km/h).
Overtaking Traffic
The figures show the vehicle
approaching (A) and passing (O)
another vehicle in the overtaking lane.
If you pass another vehicle slowly
(with a relative speed of less than
10 mph (16 km/h) and the vehicle
remains in the blind spot for
approximately 1.5 seconds, the BSA
warning light in the outside mirror
will illuminate.
If the difference in speed between the
two vehicles is greater than 10 mph
(16 km/h), the warning light will not
illuminate.
Other Cases
The BSA system is not designed to
issue an alert on stationary objects
such as guardrails, posts, walls, foliage
heaps, berms, etc. However,
occasionally the system may alert on
such objects. This is normal operation
and your vehicle does not require
service.
