Do you have any punctuation on your keyboard? It would help a lot with the readability of your post. Removing the ironic capitalization would help too.

Are you saying that traction control activates from time to time on a smooth dry road surface, or that traction control gets set off from a slippery section?

Do you mean smooth *flat* roads? Only when going uphill? Only downhill? Does it happen always at the same location(s) or randomly?

Occasionally, I'll feel a small surge or slip when running over expansion joints on a concrete highway, especially when accelerating uphill. Have never seen a Traction Control Light however.

I'm more interested into knowing why you capitalize the first letter of each word and don't use punctuation.

Sorry for the punction errors I type to fast and don't pay attention.

The traction control light comes on smooth surfaces sometimes as I apply the brake the car will jerk forward and the traction control light will come on and the car will fishtale like its trying to obtain traction. This only happened twice. The dealer said it was operating normally

This has happened to me twice, both times while accelerating from a dead stop. The first time was in the rain, so obviously I didn't think anything of it, but the second time was last week at a red light on a smooth, dry, surface and it took me a full minute to get Pablo to calm down and proceed normally...

Not sure what happened...

2 main reasons cause this.
#1 the Goodyear Integrities, I bet your Integrities have at least 20,000 miles on them, they turn into slick tires at about 15 - 20,000 and into ice skates at about 25 - 30,000
#2 overinflation (above 44 PSI)

Need to be able to disable traction control manually in an emergency. Last winter I was stopped on a slight upgrade. Road was slushy but not bad. When I started out the wheels started to slip. The traction control took over and all the car would do was make short lurches. Took forever to get through the intersection. If I could have disabled the traction control the wheels would have spun for just a second or two and then would have gripped and I would have been OK. Truck coming the other way stopped and laughed at me as I couldn't get going. First car with traction control and will be my last unless they put some kind of manual override on it.

d.j.turner@hotmail.com,

Welcome to PriusChat. You've come to the right place to get info on your Prius.

FWIW, for a good discussion of how the traction control works -- and doesn't --
see Post #4 in this thread:

Traction Control --- It worked... I Think.

You might also use the search function -- in the blue bar at the top of the
page -- using "traction control" to turn up other threads of interest.
