Cross traffic alert detects vehicles that approach at a speed between 4–37 mph (6–60 km/h). Coverage decreases when the sensors are partially, mostly or fully obstructed.

The sensor on the left-hand side is only partially obstructed and zone coverage on the right-hand side is maximized.

Zone coverage also decreases when parking at narrow angles. The sensor on the left-hand side is mostly obstructed and zone coverage on that side is severely reduced.
Note:   Slowly reversing helps increase the coverage area and effectiveness.
