2009 Mazda 6 Grand Touring: BSM? Oh, BSM!
January 20, 2009
I took the Mazda 6 this weekend to Angel Stadium to watch James "Bubba" Stewart yet again annihilate the competition at Supercross Anaheim Round 2. At the race, Dan shot a great video showing 4 consecutive backflips.
I noticed that by the driver's left knee (above), next to the unusual headlamp leveling thumbwheel, is a switch marked "BSM OFF." BSM off, what could that be? Huh.
Let's RTFM (read the friendly manual). But of course -- Blind Spot Monitoring! -- and it works just fine.
BSM works by showing a car sensing icon in either of the outside mirrors if a vehicle appears in your blindspot on the corresponding side (pic below, click on it for a better view). If you operate your turn signal to the side where the blindspot vehicle is situated, you will also hear an auditory beep. The radar sensors are located in both corners of the rear bumper. The book says you must be going 20 mph or more for it to work. I found it to be useful with no false alarms, and it never alerted for parked cars.
The only downside is that if you are cutting in and out of traffic, and not really that close to the vehicles you chop, you will get numerous warnings. Some may find it to be annoying and that all of the alerts will lead the driver to ignore the system. But I don't find it so.
Besides -- if you don't like it, there's that BSM OFF switch.
