1996 Ford Bronco Owner's Manual - Page 212

RWARNING To avoid losing control on slippery roads, do not downshift into Low with the automatic transmission when moving faster than 20 mph (32 km/h). Do not downshift into First with the manual transmission when moving faster than 5 mph (8 km/h). RWARNING The rear antilock brake system may not prevent brake lock-up on extremely slippery surfaces. Rear brake lock-up may also occur while driving in four-wheel drive because the transfer case couples the front and rear axles together. Traction-Lok Rear Axle (If equipped) This axle provides added drive away traction on slippery surfaces, particularly when one or more wheels are on a surface with poor traction. Extended use of other than matching size tires on a Traction-Lok rear axle could result in a permanent reduction in effectiveness. This loss of effectiveness does not affect normal driving and should not be noticeable to the driver. RWARNING To avoid injury, never run the engine with one wheel off the ground, such as when changing a tire. 212
