No, the light comes on when I turn on the car. Interestingly, if I start the car while holding the brake down the light does not come on until I release the brake. Also, while holding down the brake, if I hit the ASR switch the Yellow Triangle warning light comes on, and if I hit it again (still holding brake pedal down), then the Yellow Triangle warning goes off. Finally, I let up the pedal and I get the light.
