The straight driving adjustment can be done in segments as the ECU
will accumulate the information until the 800 feet is reached.
Cornering and stopping is allowed as long as calibration is done
within the same ignition cycle.
When the Straight Driving Adjustment is completed after ECU
accumulated 800 feet of straight driving, the ATC lamp will stop
blinking and will remain ON.
NOTE:
Certain vehicles may not require you to perform the turning
portion of the ESC initialization steering ratio calculation process. For
these vehicles, the ATC lamp will go out. Follow the instructions on
the screen.
The screen will automatically change to the next portion of the
procedure. Figure 9.15.

Continue driving in a circle until the screen automatically changes to
inform the steering ratio is being calculated. Maintain the vehicle
speed and conditions (approximately 8 seconds) until ATC lamp
turns off.
The screen will automatically change to the next portion of the
