The connecting cable (086b) of the measurement sensor (086a) must point towards the center of the vehicle.
Otherwise the measurement will be inaccurate.
IMPORTANT Save measured values.		  
8.1 Place measurement sensor (086a) in measurement areas (b) and measure vehicle level at measuring point 3 (left rear) and measuring point 4 (right rear). Model 167 (except 167.154/161/188/189/354/361/388/389/989) with code 490 (Electrohydraulic suspension)

11 Check maximum permissible difference in vehicle level between left and right side of vehicle at rear axle. Assign suspension data
IMPORTANT The specified test tolerance applies only when checking the vehicle level but not for calibration.		 AR40.20-P-0203ME 
  Adjust     
12 Calibrate vehicle level using vehicle diagnosis system. Model 167 with code 489 (AIRMATIC)
