	Checking
1	Carry out pre conditions and tests for vehicle level measurement		AR40.00-P-0202A
2	Clean measuring points	This prevents any measuring errors.
3	Mount measuring sensor (086a) on spring link (17) between the cast-in humps and read off the vehicle level on the inclinometer (86)	The measuring sensor connecting cable (086b) must point towards the center of the vehicle, otherwise the measurement will be incorrect.
		Measure vehicle level at Measuring point 1 (left front) and measuring point 2 (right front) and store measured values.
		Vehicle level - front axle	*BE40.20-P-1001-02I
		Electronic inclinometer (CM 9606)	*WE58.40-Z-1002-15A
4	Mount measuring sensor (086a) on rear axle shaft (65) and read off vehicle level on the inclinometer (86)	The measuring sensor connecting cable (086b) must point towards the center of the vehicle, otherwise the measurement will be incorrect.
		Measure vehicle level at Measuring point 3 (left rear) and measuring point 4 (right rear) and store measured values.
		Vehicle level - rear axle	*BE40.20-P-1001-03I
		Electronic inclinometer (CM 9606)	*WE58.40-Z-1002-15A
5	Check the maximum permissible difference in vehicle level between the left and right side of the vehicle	The specified test tolerance applies only when checking the vehicle level but not for calibration.
		Permissible difference in vehicle level at front axle between right and left sides of the vehicle	*BE40.20-P-1002-02I
		Permissible difference in vehicle level at rear axle between right and left sides of the vehicle	*BE40.20-P-1002-03I
6	Use STAR DIAGNOSIS to calibrate vehicle level	Vehicles with code (487) Active Body Control (ABC) and if the vehicle level is outside the test tolerance.
	Connect STAR DIAGNOSIS and read out fault memory		AD00.00-P-2000-04A
		STAR DIAGNOSIS diagnostic system	*WH58.30-Z-1048-13A
		Permissible difference in vehicle level at front axle between right and left sides of the vehicle	*BE40.20-P-1002-02I
		Permissible difference in vehicle level at rear axle between right and left sides of the vehicle	*BE40.20-P-1002-03I
		Possible causes and remedies when the vehicle level is not OK after calibration: Attachment of level sensor is deformed.
7	Adjust headlamps	Only if the vehicle level has been calibrated.
	Check and correct headlamp adjustment		AP82.10-P-8260R
