	Checking
	Risk of death  caused by vehicle slipping or toppling off of the lifting platform.	Align vehicle between columns of vehicle lift and position four support plates at vehicle lift support points specified by vehicle manufacturer.	AS00.00-Z-0010-01A
1	Hoist vehicle with lifting platform until wheels are free
		Model 163	AR00.60-P-1000GH
		Model 164	AR00.60-P-1000GZ

		Model 211	AR00.60-P-1000T
2	Check tires on all wheel-and-tire assemblies	Check tread as well as outer and inner sidewalls on all tires for signs of damage such as cuts, punctures, cracks, breakouts, separation and ingressed foreign matter. If damage is present ↓ Replace tire:
		Model 124, 129, 140, 163, 164, 168, 170, 171, 202, 203, 208, 209, 210, 211, 215, Model 220 except code Z07 Top protection with PAX system run-flat wheel, Model 230, Model 240 except with CSR system run-flat wheel, Model 414	AR40.10-P-1030A
		Model 220 with code 979 Special protection version with PAX system run-flat wheel	AR40.10-P-1030MB
		Model 240 with CSR system run-flat wheel	AR40.10-P-1030CSR
3	Check tire wear pattern on all wheel-and-tire assemblies	Greater wear at the shoulder compared to the center of the tire is normal for the front wheel-and-tire assemblies. Tire wear on the rear wheel-and-tire assemblies is uniformly distributed across the total tread. On rear-wheel drive vehicles the wear at the tread center is usually somewhat more pronounced than at the tire shoulders. In the case of an unusual wear pattern, determine and eliminate the cause for the increased tire wear, then: ↓ Replace tire:
		Model 124, 129, 140, 163, 164, 168, 170, 171, 202, 203, 208, 209, 210, 211, 215, Model 220 except code Z07 Top protection with PAX system run-flat wheel, Model 230, 240 except with CSR run-flat wheel Model 414	AR40.10-P-1030A
		Model 220 with code 979 Special protection version with PAX system run-flat wheel	AR40.10-P-1030MB
		Model 240 with CSR system run-flat wheel	AR40.10-P-1030CSR
	Measure
4	Measure depth of tread of all tires and note measured values on the maintenance sheet	The main tread along the entire circumference must have a tread depth of at least 1.6 mm. Measure depth of tread at point of greatest wear. Perform measurement at outside, inside and center of main tread. The wide tread grooves in the center area of the tread, which accounts for roughly 3/4 of the tread width is deemed to be the main tread. For safety reasons, tires should be replaced before the minimum depth of tread is reached: Conventional summer tires at approx. 2 to 3 mm tread depth, PAX system summer tires at 3 mm tread depth Winter tires at approx. 4 mm tread depth.

5	Interchange wheel-and-tire assemblies on front and rear axles	If necessary, and only on vehicles without mixed tires Maintain running direction of wheel-and-tire assemblies. Otherwise handling characteristics and handling comfort may be impaired and tire wear increased. Depending on the state of wear after a distance between 5000 and 10,000 km.
