Standard ride height is 790mm +/- 7mm from center of wheel arch to floor. Access level is 60mm below standard. So, from standard to access is a difference of 2.6" lower.
The problem is that you can not drive in access mode as it will go back to standard ride height if 1) the parking brake is released, 2) you put the vehicle in drive, 3) the raise switch is pressed, or 4) the inhibit switch is on. Now the question is if you open the door which freezes the ride height can you drive it?????
