brake regeneration in slippery snowy roads and traction control

[johnjackgallag]

I had a scary ride home last winter on a Vermont interstate in a snow storm. Everyone was going 25 to 40 mph and as I descended a hill on a curve I took my foot off the accelerator and as the brake regeneration came on I began to skid. This was from a speed of 25 to 30. Is there a setting to turn off regenerative braking under these conditions? Should I have been driving with traction control on?

I think it may depend on year of manufacture. On post-LCI models, the recommendation is to use DTC mode - it is designed for those conditions. It can be selected from within the iDrive user interface. It is described in the Owner's Manual.

What would happen if one's foot lifted up on the power pedal so that there's no propulsive or regenerative power (i.e., the power gauge at the 6 o'clock position) while lightly pressing the brake pedal with one's left foot to apply friction brakes on all 4 wheels? Pressing the brake pedal results in regen braking as well, so I don't know whether braking could be balanced between front and rear.
