A CAUTION: If you skip more than one gear when you downshift, you couldlose control of your vehicle. And you could injure yourself or others. Don't shift down more than one gear when you downshift. If your vehicle has four-wheel drive is equipped and with a manual transmission, disregard the shift light when the transfer case is in 4LO. All-Wheel Drive(If Equipped) If your vehicle has all-wheel drive, your engine's driving power is sent to all fourwheels for extra traction. This is like four-wheel drive, there is no but lever or switch to engage or disengagethe front axle. It is fully automaticand adjusts itself as needed for road conditions. Four-wheel Drive (If Equipped) If your vehicle has four-wheel drive, you can send your engine's driving power to all four wheels for extra traction. To shift out of two-wheel drive and into four-wheel drive, move the transfer case shift lever to 4HI or 4LO. You should use 2HI for most normal driving conditions. Locking Rear Axle If you have this feature, your rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, the locking feature will allow the wheel with traction to move the vehicle. NOTICE: Driving in the 4HI or 4LO positions for a long time on dry or wet pavement could shorten the life of your vehicle's drivetrain. 2-23
