Pidj as said below, there are several ways to lift your car, it is a matter of personal preference.

Whenever I need to get the four wheels off the ground (and level), usually I drive onto the ramps, then lift the opposite side with a floor jack, get the stands on and afterwards lift the end from the ramps and get it on the stands as well.

It may seems that you are duplicating your work but I find this a safe way to do it.

However, once the car is supported with the four stands, I give it a firm shake from side to side (both ends), to ensure that the vehicle is properly seated on the floor stands.

I already got a very close call, and you cannot take a chance because if the car falls while you are underneath, most likely you will not be able to get out of the way.... and will be very messy :-(

Please ensure that the car is 100% stable before you get under it...!
