	Check
1.1	Check whether the front torsion bar linkage is located in the outer bore of the front stabilizer bar.	Model 190 with code 478 (AMG RIDE CONTROL) except code M032 (Black Series version)
		If the front torsion bar linkage is not located in the outer bores, ↓ secure front torsion bar linkage in outer bores.	AR32.35-P-3330RG
1.2	Check whether the front torsion bar linkage is located in the inner bore of the front stabilizer bar.	Model 190 with code M032 (Black Series version) except code 478 (AMG RIDE CONTROL)
		If the front torsion bar linkage is not located in the inner bores, ↓ secure front torsion bar linkage in inner bores.	AR32.35-P-3330RG
2	Check whether the front torsion bar linkage is located in the respective center bore of the rear stabilizer bar or lever arm.	Model 190 with code 478 (AMG RIDE CONTROL) Model 190 with code M032 (Black Series version)
		If the rear torsion bar linkage is not located in the center bores, ↓ secure rear torsion bar linkage in center bores.	AR32.35-P-3329RG
3	Check if the front axle has been adjusted to the basic setting using the adjusting plate "8" between the upper transverse control arm and the wheel carrier.	Model 190 with code M032 (Black Series version)
		Check basic setting of camber on front axle If the basic setting is not set, ↓ install adjusting plate "8".	AR40.20-P-0305-01RQ
			AR33.20-P-0500RG
		Screw, upper transverse control arm holder to steering knuckle	*BA33.20-P-1008-01P
4	Check whether the basic setting of the rear axle is set on the lower control arm.	Model 190 with code M032 (Black Series version)
		Check basic setting of camber on rear axle	AR40.20-P-0306-01RQ
		For the basic setting of the rear axle, the groove of the adjusting plate on the screw head points towards the vehicle center.
		If the basic setting is not set, ↓ turn groove on adjusting plate towards vehicle center.
		Nut, lower transverse control arm to wheel carrier	*BA35.20-P-1003-07D
	Measure
5	Perform basic setting on all suspension struts.	Model 190 with code 478 (AMG RIDE CONTROL)	AR32.25-P-0001-01RG
6	Perform basic setting on coil-over suspension.	Model 190 with code M030 (GT R version) Model 190 with code M032 (Black Series version)
			AR32.25-P-0003RG
7	Deactivate rear axle steering by activating roller brake test stand mode.	Model 190 with code 201 (Rear axle steering)
			AR46.20-P-0501-01RG
		In order to ensure as accurate a measurement result as possible, the rear axle steering must be deactivated before driving onto the wheel alignment system. Tensions in the rear axle are avoided by subsequently driving onto the wheel alignment system.
8	Drive vehicle onto wheel alignment system and shift transmission to position "P".

		The wheel alignment system must be approved by Mercedes-Benz.
9	Secure vehicle with parking brake.
10	Select "Sport" drive program with drive program rotary switch (S192).	Always perform the wheel alignment measurement in the "Sport" drive program.
11	Open window of the driver's door.	Preparations for checking steering lock.
12	Switch off ignition and store transmitter key outside of transmission range (min. 2 m).
13	Prepare vehicle for wheel alignment measurement.		AR40.20-P-0260SX
14	Install brake pedal jack with adapter for brake pedal jack between brake pedal and driver's seat and clamp into place.	Protect the brake pedal and driver seat from damage. The brake pedal and/or driver seat can otherwise be damaged.
		Do not load vehicle any more.
