The Selec-Trac system is obtainable on the Rubicon mannequin and means that you can select between two-wheel drive, four-wheel drive excessive, and four-wheel drive low. The Rock-Trac system is essentially the most superior and is discovered on the Rubicon Rubicon mannequin. It includes a low-range switch case that gives extra torque for crawling over rocks and different obstacles.
Irrespective of which four-wheel drive system you may have, the method of participating it’s the similar. First, cease the car and shift the transmission into impartial. Then, pull the four-wheel drive lever into the specified place. The lever is positioned on the middle console, subsequent to the shifter. As soon as the lever is within the desired place, begin the car and drive slowly. It is best to really feel the car have interaction four-wheel drive as you drive. If you don’t really feel the car have interaction, cease and check out once more.
Interact the Switch Case
To interact the switch case in a Jeep Wrangler, observe these steps:
1. Make sure the Automobile is Protected to Interact
- Be certain that the car is parked on a stage floor.
- Place the transmission in impartial.
- Set the parking brake.
- Flip the engine off.
| Switch Case Mannequin | Lever Place for 4WD Excessive |
|---|---|
| Command-Trac | “4 HI” (label on lever) |
| Selec-Trac | “N” (impartial) to “4 HI” |
| Rock-Trac | “N” (impartial) to “4 HI” |
2. Find the Switch Case Lever
The switch case lever is often positioned on the ground of the car, between the driving force and passenger seats.
