when you start a push button starting car,don't start it directly by pressing brake and pushing the button..........because it has a bad effect on battery, ABS brake and engine oil supply.........for a safe starting in this system, firstly press the starting button gently as it lights the digital clock in dashboard.then press the button gently for the second time.it starts all the electric systems like music,tv,navigation etc.but this step also activates all electric programmes for starting the engine gently.in this step on the speedometer and odometer there will appear some optical functions like "(ABS)" . "Engine oil" indicator, a "battery" sign etc.but these items will disappear within 2 to 5 seconds.the appearance of the above items indicate that they are not activated yet for ignition but their disappearance indicate that they are prepare for ignition. For this reason, after pressing the button for the second time,wait until the above items specially the "battery" indicator disappears. When the above indicators disappear,you are safe for a better ignition system.....At this final step,put your foot on the brake pedal,press it gently and press the button.........there you will enjoy a safe and better ignitiom.That's all from me now........(amit)
