Some trailers may cause a slight change in system performance:
- Wide box trailers, especially those wider than the towing vehicle, may cause false alerts to occur when driving next to infrastructure or near parked cars. A false alert may also occur while making a 90-degree turn or driving through a roundabout.
- Wide trailers that have a total length greater than
20 ft (6 m) may cause delayed alerts when a vehicle is passing at high speed.
- Box trailers that have a width greater than
7.9 ft (2.4 m) may cause early alerts when you pass a vehicle.
- Clam shell or V-Nose box trailers with a width greater than
7.9 ft (2.4 m) may cause delayed alerts when a vehicle traveling the same speed as your vehicle merges lanes.
