This information we are about to share below will reveal whether you are professional driver or Danfo bus driver’s or quack driver’s or Learner “L”. We are very that by the time you finish reading it this special feature, You will know the category of drivers you belong to on a lighter note.
Below was the information we gathered from unannonimous source on this feature.
Very many automatic car users are careless to understand the gearing transmission system of autos.
We are aware of ‘P, R, N, D, D1, D2, D3’ or ‘P, R, N, A, 2, 3, L’ in our cars and we understand only P=park, R=reverse, N=Neutral and D=drive only.
The other’s function are discussed bellow:
“The D1, D2, D3 can be used for engine braking. That is you can use it to downshift when you are going down the hill or nearing a red light and you don’t want to use your brakes, just like in manual.
“If your are moving say in gear 4 and yo u shift to D2, your car will downshift to gear 2. likewise your car will downshift to gear 1 if your shift to D1. This is useful in slowing down the car in case of brake failure.
“For D1, when you are stucked in sand or mud, and you need to maintain gear 1 power to get your car out.
“For D2, when your are ascending a hilly road, and your engine is loosing power. To gain instant engine power, you need drop to D2( just like in manual trans).
“For D3 (if a car does not have it, OD button does the function), when you are trying to overtake in low rev say 2500 rpm and need to rev up to say 5500 rpm to gain more engine power to overtake successfully.
“Also ‘D2’ ‘D3’ functions are designed for emergency scenario, a situation where your gear in ’D’ could not change itself automatically due to electrical or mechanical malfunctioning, all you need to do is to drive the car manually and it has no side effect of on your car.
“Some automatic cars don’t have such d1, d2, rather they have +/- .The plus shifts up while minus down shifts the gear.
“Some like Mercedes have it also behind the steering like paddles. Mercedes C-class, ML and Volks Passat cars, never upshift or downshift except in extreme cases of engine revolution above or below safety limit. It makes the experience similar to driving a manual car without the third pedal.
“Unlike the manual, you can change gears to upshift or downshift as asserted without having to hit on your brake pedals at such extremes of speeding by suppressing the knob on the head of the gear shift selector handle to pick on the specified gear you wish to be on. So for automatic, if I’m moving at, say 120km/hr on ’D’, I can just change to, say ‘D2’ without stepping on the brakes, and the car will slow down automatically?
“A professional drivers use this to control when they want their cars to shift to lower or higher gears at the right rpm. A professional driver who knows how to handle auto gears will outrun an ordinary driver even when they are both driving the same cars with the same auto training. If you watch fast and furious , most of the cars they used are automatic but the drivers controlled when they want the cars to shift.”
