How do you use D 2 and L of auto gear system?

Answer 1

press in the button and move the selector to those positions. the button dose not have to be pressed to move back into drive on most cars. the car dose not have to be stopped (however sifting int L at 30+ mph can damage the transmission or engine but 2 or 3 should be fine at any speed.) these are used to help maintain traction in poor weather conditions. 2 keeps the car in a lower gear to help boost torque in icy conditions or towing. L should be used on ice only if you get stuck. also you can use them to help slow the car down when going down a steep hill L is really good at this as long as it isn't icy. D is normal driving and shifts the gears in a way that saves fuel and puts less strain on the engine. 2 or on some cars H or 3 is used as a more aggressive shifting pattern to make more torque. and L keeps the car in the gear it is until it absolutely MUST shift to prevent damage. also you can use these selections if you want a small performance boost out of your car at the expense of fuel economy. from a stand still start in L and shift up to 2 or other then to the next one if there is one then ending in drive. never shift back down to L or 1 if the vehicle is traveling over 30mph this could seriously damage the car but it also may not. this in no way makes it perform like a manual tho.
