Something that a lot of people asked me about was the tow hook on the front right side of the yaris that I used to secure my bow line. I got the idea of using it from a friend who works for NOLS. It seemed brilliant, and I did for literally 100,000 miles.
Then someone ran a red light, I hit them in the middle of an intersection, and the first point of contact was that tow hook. The impact was sudden, jarring and scary, but what didn't happen was an airbag deploy. I was going somewhere between 20 and 30 miles an hour, more than fast enough to trigger a discharge.
The fire department was concerned about it, and mentioned several times that they were surprised they didn't deploy, they were disconnecting the battery (normal procedure is to cut the battery cables, as a courtesy they took the time to simply disconnect them, I think because I identified myself as a former medic) and they told me not to drive the car. Not that I could.
I commented to many people that I was surprised that the airbags didn't deploy - most resulting in funny comments like "oh on the yaris, you have too blow up the airbags yourself." I even went as far to mention it here on the blog.
Then I got this comment from a reader named Kiradale:
I recently purchased a VW Golf wagon. The owners manual warns against driving with the tow eye in place on the front bumper as it may affect deployment of the air bags in the event of a collision.
I did some research, but couldn't find anything online, linking tow hook usage to a lack of airbag deployment on the Yaris, but honestly, it makes complete sense that having that hook could alter airbag deployment. In this case anecdotal evidence is enough.
So please, don't use the tow hook on the front of your car - any car - as a method for securing your bow lines. If there is even a chance it will keep your airbags from deploying it isn't worth the convenience.
Instead I will be using these:
The Seattle Sports quick loops is one of those things I wish I had invented. Put the rubber tube part under your hood, and let the loop part stick out. Tie off to that, and you are good to go. At least I hope you are good to go, I haven't used them yet. Ill keep you posted.
And do me a favor. Drive carefully!
