CONTROL TRAC FOUR-WHEEL DRIVE (4X4) OPERATION

(IF EQUIPPED)

For important information regarding safe operation of this type

of vehicle, see Preparing to drive your vehicle in this chapter.

If equipped with the Control Trac 4x4 System, and 4L (4x4 LOW)

is selected while the vehicle is moving, the system will not

engage. This is normal and should be no reason for concern.

Before 4L (4x4 LOW) can be engaged, the vehicle must be

brought to a complete stop, the brake pedal depressed and the

transmission placed in N (Neutral).

The vehicle should not be operated in 4H (4x4 HIGH) or 4L (4x4 LOW)

on dry pavement. Doing so could result in difficult disengagement of the

transfer case, increased tire wear, decreased fuel economy and may

damage driveline components.

Your 4x4 features the heavy-duty Control Trac system which includes a

computer-operated transfer case. This unique system is interactive with

the road, continually monitoring and adjusting torque delivery to the

front and rear wheels to optimize vehicle control.

System indicator lights

The Control Trac system indicator lights illuminate only under the

following conditions. If these lights illuminate when driving in 2H or

A4WD, contact your Ford dealer as soon as possible.

• 4X4 HIGH - momentarily

illuminates when the vehicle is

started. Illuminates when 4H is

selected.

• 4X4 LOW – momentarily

illuminates when the vehicle is

started. Illuminates when 4L is

selected.
