122 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
Overtaking Traffic
If you pass another vehicle slowly with a relative speed
of less than 15 m.p.h. (24 km/h) and the vehicle remains
in the blind spot for approximately 1.5 seconds, the
warning light will be illuminated. If the difference in
speed between the two vehicles is greater than 15 m.p.h.
(24 km/h), the warning light will not illuminate.
Overtaking/Approaching
The BSM system is designed not to issue an alert on
stationary objects such as guardrails, posts, walls, foliage,
berms, etc. However, occasionally the system may alert
on such objects. This is normal operation and your
vehicle does not require service.
