(i) Using the DATA LIST, confirm that the vehicle height control operation is complete.
(j) Turn the power switch OFF.
(k) Move the shift lever to N and move the vehicle forward and rearward.
2. INSPECT VEHICLE HEIGHT
(a) Inspect the vehicle height Front Wheel Alignment.
(b) Perform vehicle height offset calibration Testing and Inspection.
NOTICE:
The possible vehicle height automatic adjustment value is 20 mm (0.787 in.). If "Height Adjust value + (Standard value - Measurement value - After Height Adjust value)" is 20 mm (0.787 in.) or more, first perform the standard vehicle height adjustment (height control link adjustment).

3. ADJUST HEIGHT CONTROL SENSOR LINK SUB-ASSEMBLY (for Front)
NOTICE:
- First adjust the height control sensor link that has the highest deviation from the standard value.
- If the deviation of the front and rear link is the same, adjust the front link first.





(a) Loosen the 2 lock nuts on the height control sensor link.
(b) Turn the bolt of the height control sensor link to adjust the length.
HINT:
- If raising the vehicle height, lengthen the link.
- If lowering the vehicle height, shorten the link.
- Turning the bolt of the height control sensor link 1 revolution changes the vehicle height by about 6.9 mm (0.272 in.).





(c) Check if the height control sensor link length shown in the illustration is less than the maximum value.

Torque: 5.3 Nm (54 kgf-cm, 47in-lbf)
(d) Perform vehicle height offset calibration once again.
(e) Inspect the vehicle height once again.
5. INSPECT WHEEL ALIGNMENT
(a) Inspect the front wheel alignment Front Wheel Alignment.
(b) Inspect the rear wheel alignment Rear Wheel Alignment.
