You can use the autopilot feature only at a station installed next 

to a helm, throttle, and helm control device.
You are responsible for the safe and prudent operation of your 

vessel. The autopilot is a tool that enhances your capability to 

operate your boat. It does not relieve you of the responsibility of 

safely operating your boat. Avoid navigational hazards and 

never leave the helm unattended.
Always be prepared to promptly regain manual control of your 

boat.
Learn to operate the autopilot on calm and hazard-free open 

water.
Use caution when operating the autopilot near hazards in the 

water, such as docks, pilings, and other boats.
The autopilot system continuously adjusts the steering of your 

boat to maintain a constant heading (heading hold). The system 

also allows manual steering and several modes of automatic-

steering functions and patterns.

À

Actual heading

Á

Intended heading (heading the autopilot is steering toward)

Â

Actual heading (when in standby mode)
Intended heading (when engaged)

Ã

Rudder position indicator (This functionality is available only when a 
rudder sensor is connected.)

From the Autopilot screen, select MENU > Autopilot Setup > 

Step Turn Size.

Select an increment.

You can adjust the level of rudder activity.

From the autopilot screen, select MENU > Autopilot Setup > 

Power Mode Setup > Power Saver.

Select a percentage.
Selecting a higher percentage reduces rudder activity and 

heading performance. The higher the percentage, the more 

the course deviates before the autopilot corrects it.
TIP: In choppy conditions at low speeds, increasing the 

Power Saver percentage reduces rudder activity.

When you engage the autopilot, the autopilot takes control of the 

helm and steers the boat to maintain your heading.

From any screen, select Engage.
Your intended heading shows in the center of the Autopilot 

screen.
