Proper techniques for operating steering wheel
A. Push & Pull Technique
Imagine the steering wheel is a clock. Place your hands on 10 and 2 positions. If you want to turn the steering wheel to the left, push the S/W to the left with your right hand and at the same time slide your left hand to the top, till your hands meet each other at the top.
Then, pull the S/W down to the 10 position with the left hand and at the same time, slide your right hand to the 2 position. Repeat the same process if you need to turn the wheel more.
For the right turn, use the exact same technique but starting from the opposite hand. In this demonstration, only the left turn is shown.
