170 / AUTO STEERING PERFORMANCE
AUTO STEERING DISENGAGE
User disengagement can occur by performing the following:
• Press the Auto Steer button on the main guidance screen
• Manually turn the steering wheel
Manual turn of the steering wheel is a safety feature to gain immediate
control of the vehicle.
Disengagement can also occur due to a non-console input, such as losing
satellites or losing the guideline.
LIMITATIONS
• Manual control of the vehicle is required to perform sharp turns,
including U-turns, and 90 degree angles.
• Driving at a high speed reduces the effectiveness of the auto steering
system due to the physical limitations of the hydraulic system and the
AES-25 electric steering system. High speeds require faster steering
adjustments that may cause wheel oscillation and poor guideline
adherence.
Pay close attention to immediate surroundings when autosteering
is engaged.
