1	Checking and preparing for wheel alignment		AR40.20-P-0060AC
2	Position front wheels of vehicle on turnplates		AR40.20-P-0200-12AC
		If using an electronic measuring system with integrated turnplates, the measuring system must be approved by Mercedes-Benz.
3	Insert brake pedal winch on brake pedal	Brake pedal jack	Fig 2
4	Open window
5	Switch off ignition
6	Fit quick-clamping devices on front and rear wheels		AR40.20-P-0231AC
7	Attach and calibrate measurement pickups	Refer to measuring system operating instructions.
8	Determine specified value for caster	Determine caster value Fluctuations in axle load for the various models will cause the caster angle to change depending on the vehicle load relative to the spring travel. It is not possible to correct the caster angle on the vehicle. The specified caster angle is changed only if the trailing arms are bent or the axle tubes are twisted.	AR40.20-P-0336AC
9	Release turnplates
10	Perform initial measurement	Refer to measuring system operating instructions.
		Difference in wheelbase between left and right sides	*BE40.20-P-1006-11A
		Toe-out on turns with the inside wheel steered through 20°	*BE40.20-P-1005-11A
		Steering axis inclination	*BE40.20-P-1004-11A
		Caster	*BE40.20-P-1003-11A
		Camber	*BE40.20-P-1002-11A
		Toe-in	*BE40.20-P-1001-11A
11	Evaluating measurement results	If no fault is found after evaluating the measurement results, the wheel alignment is complete. Proceed with step 14.
12	Adjust front axle toe	Check and adjust front axle toe	AR40.20-P-0323GG
13	Perform final measurement	Refer to measuring system operating instructions.
		Difference in wheelbase between left and right sides	*BE40.20-P-1006-11A
		Toe-out on turns with the inside wheel steered through 20°	*BE40.20-P-1005-11A
		Steering axis inclination	*BE40.20-P-1004-11A

		Camber	*BE40.20-P-1002-11A
		Toe-in	*BE40.20-P-1001-11A
14	Detach measurement sensors	Refer to measuring system operating instructions.
15	Remove quick-clamping devices from front and rear wheels		AR40.20-P-0231AC
16	Remove brake-pedal winch	Brake pedal jack	Fig 2
17	Lock turntables
18	Drive vehicle off measuring system
19	Check straight-line stability and turn-signal cancellation during a test drive
