Activating and Deactivating SGA Alerts
SGA is automatically activated when the ignition is turned on. ASGA, if equipped, relies on SGA and is not controlled separately by the driver. 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, ASGA automatically applies the brakes.
Although monitoring is continuous, the audible and visual alerts can be deactivated fully or partially. With the default setting, SGA notifications are active for the vehicle. Stationary and moving objects detected within range activate cautions and warnings. The driver can turn SGA alerts off manually using the driver assistance settings in the driver display. See Fig. .

In some operational conditions, such as construction zones, SGA may register false positives. A driver can override ASGA braking, by pressing the accelerator pedal beyond the pressure point to engage kickdown.
For common warning scenarios when SGA is activated, see Table .
Table 1, Common Scenarios for Warnings While SGA and Trailer Assist are Activated
|
Warning Scenarios |
Driver Experience |
|---|---|
 |
Moving object detected along side the vehicle and trailer. An amber SGA warning lamp in the A-pillar activates and the ICU displays the appropriate caution telltale. |
 |
Moving detected while turning. If the driver signals or steers to the passenger-side and there is a risk of collision with an object, the red SGA warning lamp in the A-pillar flashes for a few seconds, a warning tone sounds, and the appropriate SGA warning telltale on the driver display screen. After flashing, the red warning lamp stays on as long as there is a risk of a collision. If the vehicle is moving at urban speeds and equipped, ASGA automatically applies the brakes. |
 |
Limitations to detection of risk to the trailer's back corner while turning. The ability of SGA and ASGA to detect and react to stationary objects alongside the end of the trailer as it completes a passenger-side turn is limited. If the driver steers to the passenger-side there is a risk of collision without notification when the end of the trailer and its bumper reaches a stationary object. |
 |
Moving object detected by vehicle sensor before a lane change. If a moving object is in SGA monitoring range when a driver signals or steers to the passenger-side, an amber warning lamp activates in the A-pillar and the appropriate SGA caution telltale appears on the driver display screen. If there is a risk of collision, the red warning lamp in the A-pillar flashes, a warning tone sounds, and the appropriate SGA warning telltale appears on the driver display screen. The red warning lamp stops flashing after a few seconds but stays on as long as there is a risk of a collision. |
