1 Position the vehicle for measuring on a horizontal and flat area
When positioning the vehicle, in the measuring area, make sure the chassis is not submitted to tensions due to the drive towards the measuring area performed with very sharp curve or abrupt moves. If possible, when the vehicle is positioned in the measuring area, reverse a certain distance in a straight line and position it again forward, always in a straight line and without abrupt moves. This will permit that the structure is in a least tensioned possible situation.
2 Check the tire inflation pressure and, if necessary, correct.
3 Control the springs and shock absorbers
The springs are to be at the same height.
