Snow mode can be selected when driving on slippery surfaces. Electronic assistance systems adapt to this situation straight away. The Anti-Lock Braking System (ABS) allows slightly more wheelspin. As a result, snow accumulates in front of the tyres and the braking effect is increased. Traction control (TCS) allows more wheelspin so that the tyre tread grips more effectively and the gearbox selects higher gears than it normally would in the lower speed range. The accelerator reacts more smoothly and thereby prevents an undesirable increase in the amount of torque. This prevents the wheels from spinning.
