Assalam-u-Alaikum everyone
I recently starting driving an automatic car and I feel difficulty sometimes driving it so I would like to ask that on which gear is it suitable to drive in the Karachi city, I have Automatic Swift 2018; the gears are D, D-3, D-2 & L ? Because while driving on the 'D' I feel that the speed doesn't increase above 40 and if I pushes the accelerator the RPM goes above 3.So kindly guide me that what should be best?
And what is RPM what's the purpose of it and what should be, its to maintain the fuel average?
