I'm not defending the guy in the car, or Volvo, or any of the idjits casually standing in the forward path of the car with this post, but car manuals don't always make clear what special features are actually equipped on specific vehicles. I haven't RTFM for this particular vehicle, but often times manufacturers will save money by making a standard Manual that spans all trim classes and features of that vehicle model with little footnotes to say which trim package has a particular feature, or just "check with your dealer/manufacturer for specified feature."
My Manual for my Chevrolet Traverse gives all the possible features that the model could have for every trim package available, with blurbs specifying "check with your dealer to see if your vehicle has this feature." Being a used vehicle, my dealer couldn't tell me what features the thing was supposed to have. Even though it has the LT trim stickers, being that it was originally a fleet vehicle (found that out after extensive searching of the VIN, beyond what even CarFax had access to) many of the standard LT features (proper sensors for the OnStar system, automatic mirror adjustment for viewing the wheels while backing up, etc) were not found anywhere on the vehicle. On a side note: At the time of sale having three known non-working features that an LT model was supposed to have before I even knew that it was a fleet vehicle, I was able to get the dealer to cut almost $10K from the price and have them sell an AWD LT model for the same price they offered as the 2WD LS base model. If I had been able to prove it was fleet before the sale, I could have had even more knocked off. Also, came to find several more trim discrepancies later on; but there's more important things about that PoS that piss me off more than what trim features it's missing (dear god, I can see more around my 1990 G20 Conversion Van than I can see around this PoS). From someone who's been brand loyal to Chevy for 20 years, this will be my last GM vehicle newer than 2000.
That said, playing devil's advocate it could have been that the dealer told him that this vehicle had the pedestrian safety feature as part of the automation package, and he felt he was getting a great deal for the extra features...that the car didn't really have. And depending on how the manual was written, it could be very ambiguous as to whether the feature was really in the package or not, telling the person to check with the dealer or manufacturer to see if said feature was available.
