What should be done on hills to prevent excessive shifting while towing?

Utilizing tow mode is the most effective way to prevent excessive shifting while towing on hills. When engaged, tow mode adjusts the vehicle's transmission behavior to optimize power and torque, which helps maintain a steady speed and reduces the need for frequent shifting. This is particularly useful in hilly terrain, where the vehicle may otherwise switch gears too often as it responds to changes in load and gradient. By keeping the engine in the optimal power band, tow mode helps enhance vehicle stability and overall performance when towing heavy loads.

Increasing speed may seem like a possible solution, but it can lead to over-revving the engine and increased wear on transmission components, potentially resulting in less control on steep inclines. Turning off the vehicle is impractical and unsafe, as it would eliminate the ability to maneuver and control the truck effectively during towing. Reducing trailer weight can help ease the towing burden, but it is not always a feasible option, especially when the load is necessary for a particular task. Thus, engaging tow mode serves as the best practice for handling towing on hills efficiently.
