I purchased the Gx460 to aquire the new safety bsm system. The owners manual (pg366) reqires the side mirror indicator light comes on at 9. 8 feet behind the rear bumper of my vehivle. The light on the side mirror comes on when the vehicle passing me is at my rear bumper making it dangerous to change lanes and would not allow the approaching vehicle enough time to avoid a collision. I have checked with 2 dealers and both said there is no adjustment for this condition. I finally was able to have one dealer check the computer and was told all is normal. I asked my daughter-in-law to whitness this event from the back seat and she varified my findings.
