I h've a 2004 Mazda6, and i would like to know what is the correct way to start moving the car after engine starts
shifting directly ''D'' drive and move, shifting ''S'' or ''L'' ?

your help is much appreciated

 

Based upon the way you asked the question, I would say the ONLY three positions you should use for your gear selector are as follows:

• P - Park
• R - Reverse
• D - Drive

Under no circumstances should you use "S" or "L" until you've fully read your Owner's Manual.
