Check owner's manual. If you don't have one copy and paste link below; www.fleet.Ford.com/maintenance/owners_manuals ---------------------------------------------------------------CONTROL TRAC-AUTOMATIC FOUR-WHEEL DRIVE SYSTEM (IF EQUIPPED) Your 4x4 features a heavy-duty Control Trac system, includes a computer-operated transfer case. Coupled with a center-disconnected front axle, this unique system is interactive with the road, continually monitoring and adjusting torque delivery to the front and rear wheels to optimize vehicle control. Positions of the Control Trac system The Control Trac A4WD system functions in four modes: ² 2H position delivers power only to the rear axle. ² A4WD position delivers power to the rear axle, and the front axle when road conditions dictate the need for increased traction. ² 4H position provides mechanically locked four-wheel drive power delivery to front and rear axles. ² 4L position provides mechanically locked four-wheel drive when above average power at reduced speeds is required.

Avoid sharp turns or abrupt maneuvers in these vehicles. Using the Control Trac system Shifting to A4WD Move the 4WD control to A4WD at a stop or at speeds up to 88 km/h (55 mph). ² At temperatures below 0° C (32° F), shifts from 2H to A4WD or 4H should not be performed above 72 km/h (45 mph). ² Do not shift into A4WD when only the rear wheels are spinning. Shifting to 2H Move the 4WD control to 2H at any forward speed. 2H 4L A4WD 4H 2H 4L A4WD 4HDriving 120 Shifting from 4H to 4L (and 4L to 4H) 1. Bring the vehicle to a stop. 2. Depress the brake. 3. Place the gearshift in N (Neutral). 4. Move the 4WD control to the 4H (or 4L) position. Shifting from A4WD to 4H Move the 4WD control from A4WD to 4H at any forward speed. Shifting from 2H to 4H can be done at speeds up to 88 km (55 mph). 2H 4L A4WD 4H 2H 4L A4WD 4H Driving 121 Driving off-road with 4WD Your vehicle is specially equipped for driving on snow, sand, mud or other rough terrain and has operating characteristics that differ from those of other conventional vehicles. When using 4WD, maintain steering wheel control at all times, especially in rough terrain. Since sudden changes in terrain can result in abrupt steering motion, always grip the steering wheel from the outside. Do not grip the spokes. Drive cautiously to avoid vehicle damage from road debris such as rocks or stumps. Be sure to map out your route before driving in any off road area. For more information on driving off-road and proper operation of your 4WD vehicle, refer the Four Wheeling supplement in your Owner's Portfolio. Driving 122
