NOTE:

Check compliance with test conditions , bring vehicle to a stop if necessary. See 32 00... TEST CONDITIONS FOR CHASSIS/WHEEL ALIGNMENT CHECK .
If the ride height is outside the tolerance range (+40/ -20 mm), the vehicle must be loaded and measured/aligned in the design position . See 32 00... MOVING VEHICLE INTO DESIGN POSITION .
Calibrate reversing camera (RFK) after chassis/wheel alignment. See 66 53 010 CALIBRATING REVERSING CAMERA .
