The differential lock is activated by a switch on the dash,` as shown in Fig. , or activated on the Axles screen The driver-controlled differential lock (DCDL) feature (side-to-side wheel lock, traction control, or traction equalizer) is an option available on eCascadia vehicles with single- or tandem-drive axles equipped with a Detroit e-axle.

The DCDL provides maximum traction for slippery conditions by forcing the wheels on each drive axle governed by the switch to rotate together. When the DCDL is engaged, the clutch collar completely locks the differential case, gears, and axle shafts together, maximizing the traction of both wheels.

The axles menu is on the infotainment display accessed by switch 5 as shown in Fig. .
