	Measure
1	Observe general information on chassis alignment		AR40.20-D-0201H
2	Drive vehicle on to measuring system	 The measuring system must be approved by Mercedes-Benz.
3	Insert brake pedal jack between brake pedal and driver seat	 Use the  brake pedal jack carefully. The driver seat can otherwise be damaged.
		 You only need apply slight pressure to the brake pedal.
