Good luck getting a response
Good luck getting a response from Toyota on the ability of the forward collision prevention system to stop for deer. We have a lot of deer and deer-car collisions where I live, so I asked Toyota about the ability of the system to detect and stop for deer, since it is says it detects pedestrians and bicyclists.
Toyota just regurgitated the statement in the manual about pedestrian and bicyclist detection. They won't assure us that the system will detect deer, moose or other large animals of that sort. Totally useless and unhelpful answer.
