CTS buttons next to auto shifter

[eldo99er]

Can someone tell me what those buttons on top of P and below 2 are for? One looks like a snowflake symbol, the other like an "S" in the middle of a sun?
Thanks!

The one (snowflake) is for snow & ice conditions, The other is the sports mode for the transmission. Keeps it in gear longer or something like that.

Snowflakes and speed

Those buttions are for extra settings that the car comes with. The snowflake is for snow and icy conditions. The s buttion is for speed. what the car does when you press that buttion the suspension tightens for better handling and you would stay in gear longer getting more torque. I was driving in my CTS when a chick looked and then passed me in her pontiac. I pressed the buttion and you can feel the car like drop to get lower to the ground and then it just bolted off with a brust of speed
