SERVICE INFORMATION
When performing Direct Adaptive Steering (DAST) Calibration (Mode 1):

Always use an alignment rack with the front wheels positioned on the turntables and the pins
removed. The front wheels must be allowed to move freely.

DO NOT perform DAST Calibration (MODE 1) with the front wheels in any other position then listed
above.
NOTE: As of the publication date of this bulletin, the Electronic Service Manual (ESM) states; “Lift up
vehicle or set the front wheels on the turntable”. Lifting up the vehicle is incorrect.

To prevent damaging the spiral cable during DAST Calibration (MODE 1), follow instruction in the ESM.
After performing DAST Calibration (MODE 1), if there is a steering wheel off-center or a vehicle pull condition,
perform DAST Calibration (MODE 1) again, making sure to use an alignment rack.
NOTE: Do not perform a wheel alignment for a steering wheel off-center or pull condition.

applies to your vehicle.
