Adjusting the heights.
Calculate the following values:
- Front LH: K1M = R1 - H1M.
- Front RH: K2M = R2 - H2M.
- Rear LH: K3M = R3 - H3M.
- Rear RH: K4M = R4 - H4M.

Adjustment of vehicle reference heights.
Enter the values K1M, K2M, K3Mand K4Min the diagnostic tool.
WARNING: The values should consist of 4 figures: Example: K1 = 160 mm - enter the value 0160.
Checking the heights after adjustment.
Check the heights:
- Front LH: K1 = 160 ± 6 mm.
- Front RH: K2 = 160 ± 6 mm.
- Rear LH: K3 = 111 ± 6 mm.
- Rear RH: K4 = 111 ± 6 mm.
