Step by step.
- 01
Use E-Lock only when the truck is stuck or becoming stuck, and first try freeing it with the transfer case in 4LO.
- 02
Stop the truck or reduce speed to 4 mph (7 km/h) or less, make sure the tires are not spinning, and keep 4LO selected.
- 03
Press the E-Lock switch ON; allow slight wheel movement if needed for the clutch to align.
- 04
Wait for the E-Lock indicator to stop flashing and remain solid before applying gentle throttle.
- 05
As soon as the truck is free, stop using the added traction and switch E-Lock OFF.
Important limits
- Do not use E-Lock on paved or hard surfaces, snow, or ice; it is intended only to free a stuck vehicle.
- ABS and Vehicle Dynamic Control are disabled while E-Lock is engaged.
- Do not exceed 12 mph (20 km/h) with E-Lock engaged and never switch it on while the tires are spinning.
Quick checks.
- ✓If the indicator keeps flashing, confirm 4LO is selected and vehicle speed is 4 mph or less.
- ✓Let the truck creep very slightly to align the locking clutch, but stop immediately if wheelspin begins.
- ✓If the indicator will not become solid under correct conditions, switch the system off and have it inspected.
