been set incorrectly, system will not be able to accurately determine a heading. Drive vehicle forward for 500 feet
(152 meters) and then restart calibration.
Tilt Zero
System uses its sensors to determine tilt of vehicle as it travels through the field. This allows system to calculate true
position if the cab is tilting to one side or another. If tilt of vehicle is not accurately measured, system will not be able to
autosteer the vehicle accurately.
Tilt calibration is a two step process.
1.
Vehicle must be parked on a flat area and left to sit. System then averages sensor readings for a short time to get a
base line.
2.
Vehicle must then be driven and turned around to face opposite direction and stopped at exact same spot. System
then averages sensor reading while faced in other direction.
System is now able to use two readings to zero out slight tilt errors of gyros.
Initial Direction
÷
NOTE!: It is important that Tilt Calibration takes place on a flat area with no slope. If this step is performed on a slope,
system may not be able to accurately control vehicle.
To start Tilt Zero Initial Direction calibration, drive vehicle onto a flat surface and put in park or set park brake. Press Resume
button and wait for system to finish this step. When this step is complete, calibration process will automatically move on
to next step.
Opposite Direction
This is second stage of this calibration procedure.
÷
NOTE!: It is important that vehicle is positioned in exact same place as previous step but facing in opposite direction.
If vehicle is not placed in same position, tilt compensation will be incorrectly calculated and vehicle steering
performance will be degraded.
To finish Tilt Calibration, turn vehicle around and park in exact same location so that rear tires are now over marks of front
tires (center of track is at same point but in opposite direction). Press the Resume button and wait for system to finish
measuring.
System will then automatically jump to the next step. This is the end of Common Calibration Steps.
VEHICLE TYPE SPECIFIC CALIBRATION STEPS
Depending on vehicle type, Auto Calibrate wizard will move to one of three different procedures to calibrate remaining
sensors. Follow procedure for vehicle type that system is being installed on.
Valve / Steer-by-Wire
This vehicle type has a steering valve that is controlled directly by system. This includes vehicles that use standard
AutoSteer valves, AutoTrac Ready (non ISO), AccuGuide Ready, IntelliSteer, and others. There are three steps to finish
calibration process.
Valve Deadband
—Determines valve’s deadband or minimum signal that must be sent to start oil flow.
Angle Sensor
—Calibrates Angle Sensor on steering axle.
Valve
—Calibrates hydraulic valve.
Next step of calibration process should start automatically from Common Calibration Steps.

NOTE!: Verify that engine RPM is at working speed while this part of calibration is taking place.
