* Your vehicle is struggling to maintain speed. This is especially important when driving uphill or in heavy traffic. Downshifting will give your engine more power to propel the vehicle forward.
* You are about to come to a stop. Downshifting will help you to slow down gradually and smoothly.
* You are about to turn. Downshifting will help you to enter the turn at a slower speed, which is safer.
* You are driving on a slippery road. Downshifting will help you to maintain traction and avoid skidding.
* You are towing a load. Downshifting will help to reduce wear on your transmission and brakes.
Note: It is important to avoid downshifting too early. This can damage your transmission. If you are not sure whether or not to downshift, err on the side of caution and leave it in the gear you are currently in.
