Slip Indicator dash light coming on - why?

[BigBad64]

My wife has reported that the "Slip Indicator" dash light (the little graphic of the car with the skid marks behind it) has been coming on intermittently and flashing in normal braking situations when neither the VSC or Traction Control has been activated. Dry roads, gradual braking for a red light was the last instance today apparently.

Looking at Pg 181 of the manual it says that a buzzer will sound intermittently when VSC is operating. She says there has been no buzzer.

I suppose I'll have to do what it says on Pg 183;

"If the slip indicator comes on it may indicate a malfunction in the VSC and TRC. Contact your Toyota dealer."

Has anyone else experienced this issue?

If this occurs when there is definitely no slip, it can usually indicate one or more of your ABS sensors (located on each wheel and monitors rotation) are not functioning 100%. This would mean that for example, one sensor is not seeing one full revolution as such and it would then think it is slipping. If it was to only occur once in a blue moon, I wouldn't really think about it much, but if it happens say more than a few times in a few days or so, I'd definitely see if Toyota can check it out.

Thanks for the reply.

I went for a trip in it yesterday as front seat passenger and read the manual in detail. It appears as though she has been unintentionally activating the "Hill Assist Control" feature which makes the slip indicator flash. I explained how this worked to her and we tested it out and she thinks that is what she had been seeing.

We didn't see the slip indicator light come on any time it wasn't meant to during yesterday's trip.

We'll keep an eye on it but I think it's just been doing exactly what it's meant to do. :D
