this is to put the brake on while in traffic, HOLD will illuminate to be shown on the instrument cluster... to do this when driving come to a stop normally and then press the brake again.... HOLD will show in cluster, then just accelerator to move off... works nicely...
I think this is why one occasionally hears odd noises when pulling away on an incline; because the car is being held on the brake and then automatically being released as you press the accelerator. I think it's the noise of the pads releasing the huge disks at the same time as the drive engages.
