Up-Shift Light If you have a manual transmission, you may have a shift light. This light will show you when to shift to the next higher gear for best fuel economy. Four-Wheel Drive If your vehicle has four-wheel drive, you can send your engine's driving power to all four wheels for extra traction. To get the most satisfaction out of four-wheel drive, you must be familiar with its operation. Read the part that follows before using four-wheel drive. See the appropriate text for the transfer case in your vehicle. When this light comes on, you can shift to the next higher gear if weather, road and traffic conditions allow. For the best fuel economy, accelerate slowly and shift when the light comes on. While you accelerate, it is normal for the light to go on and off if you quickly change the position of the accelerator. If your vehicle has four-wheel drive and is equipped with a manual transmission, disregard the SHIFT light when the transfer case is in 4-Wheel Low. Ignore the SHIFT light when you downshift. Notice: Driving on pavement in four-wheel drive for an extended period of time may cause premature wear on your vehicle's powertrain. Do not drive in four-wheel drive on pavement for extended periods of time. Front Axle Locking Feature The front axle locks and unlocks automatically when you shift the transfer case. Some delay for the axle to lock or unlock is normal. 2-33
