Activating and Deactivating Side Guard Assist

SGA becomes active when the ignition is turned on. The driver controls its setting using the driver assistance screen of the ICU also known as the digital switch or a physical switch if equipped.

In some operational conditions, such as construction zones, SGA may register false positives. Vehicles built from January 2023 have an optional SGA OFF physical switch as shown in Fig.Physical SGA OFF Switch.

While the vehicle is running and SGA is OFF, the driver display shows the side guard assist deactivation or error telltales as shown in Fig.Side Guard Assist Telltales.

After SGA is turned off, it remains off until the driver turns the SGA feature ON using one of the following:

• the switch, if equipped,

• the driver assistance screen on the driver display,

• stopping and turning the vehicle off and on again.

SGA is automatically activated when the ignition is turned on. The ASGA relies on SGA and its activation is not controlled separately by the driver. The ASGA engages at speeds less than 12 mph (19 km/h). If SGA detects a critical moving object in the sensor monitoring area along the side of the truck during a passenger-side turn, the ASGA automatically applies the brakes.

Although monitoring is continuous, the audible and visual alerts can be deactivated fully or partially. With the default setting, the SGA notifications are active for both the vehicle and the trailer as shown in Fig.Notification Zones for SGA and Trailer Assist While Activated.. Stationary and moving objects detected within range activate cautions and warnings.

If the digital settings for the trailer are deactivated, notifications are deactivated for the range indicated as a red circle with a slash shown in Fig.Notifications Zones for SGA Active and Trailer Assist Deactivated..

A driver can override SGA and ASGA during a braking event by pressing the accelerator pedal beyond the pressure point to engage kickdown.

The driver can keep the default settings for SGA notifications to alert for objects within the range of the vehicle and the trailer; or filter out objects detected on the passenger-side of the trailer. Also, the notifications can be deactivated for both.

In some operational conditions, such as construction zones, SGA may register false positives. The driver can turn SGA alerts off manually for the truck and trailer using the driver assistance settings of the driver display. If SGA is off, the trailer monitoring is off. The driver can keep SGA on for the vehicle and deactivate the trailer alerts.

After stopping safely, the driver can use the driver display to change the alert settings. For vehicles equipped with ICUC, the settings are shown in Fig.Deactivation of SGA in the Driver Display, ICUC and see Fig.Deactivation of Trailer Assist in the Driver Display, ICUC.

For vehicles equipped with ICC5, the display has digital toggles for turning features on and off. The alert settings are shown in Fig.Deactivating SGA in the Driver Display, ICC5 and see Fig.Deactivating SGA Trailer in the Driver Display, ICC5.
