Operating Information And Precautions

~2min read

The Command-Trac II transfer case provides four positions:
• Two–wheel drive (2WD) high range
• Four-wheel drive (4WD LOCK) high range
• Four-wheel drive (4WD LOW) low range
• Neutral (N)

This transfer case is intended to be driven in the twowheel drive position (2WD) for normal street and highway conditions such as dry hard-surfaced roads.

When additional traction is required, select the transfer case 4WD LOCK position or 4WD LOW position. This position locks the front driveshaft and rear driveshaft together and forces the front and rear wheels to rotate at the same speed.

Use the transfer case NEUTRAL position for recreational towing only. Refer to “Recreational Towing” in “Starting and Operating” for further information.

• The 4WD LOCK position and 4WD LOW position are intended for loose or slippery road surfaces only. Driving in these positions on dry hardsurfaced roads may cause increased tire wear and damage to the driveline components.

• When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the 2WD position or 4WD LOCK position at a given road speed. Take care not to over-speed the engine and do not exceed 40 km/h.

• Proper operation of four-wheel drive vehicles depends on tires of equal size, type, and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. Tire rotation schedule should be followed to balance tire wear.

• Always engage the parking brake when powering down the vehicle if the “SERV 4WD Warning Light” is illuminated. Not engaging the parking brake may allow the vehicle to roll, which may cause personal injury.

• Since four-wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road conditions permit. You or others could be injured.
