2

Clean measuring points

 This prevents any measuring errors.

3

Insert measuring sensor (2) with measuring tips (4) into the measuring points (arrows) at left and right of the transverse control arm (7) and read off the vehicle level on the inclinometer (1)

 The connecting cable of the measuring sensor (3) must point transverse to the direction of travel relative to the front axle carrier otherwise an erroneous measurement occurs.

 Measure vehicle level at
 Measuring point 1 (left front) and
 measuring point 2 (right front) and store measured values.

6

Apply measuring sensor (2) with measuring tips (4) onto measuring points (6) of measuring plate (5) and read off the vehicle level on the inclinometer (1)

 The connecting cable of the measuring sensor (3) must point in direction of travel, otherwise an erroneous measurement occurs.

 Measure vehicle level at

 measurement point 3 (left rear) and

 measurement point 4 (right rear) and store values.
