What Does Tow Haul Mode Do on a Truck?

Tow haul mode is a feature found on many modern trucks and SUVs which can provide a number of benefits to the driver. Specifically, tow haul mode allows for increased engine braking, improved transmission performance when towing, and improved fuel economy.

When the tow haul mode is engaged, the engine braking is increased. This means that the engine will slow down the vehicle more quickly when you let off the accelerator.

This can be especially useful when driving downhill with a heavy load or trailer behind you. In this situation, tow haul mode can help you maintain control of your vehicle and make it easier to keep your speed under control.

In addition to increasing engine braking, tow haul mode also optimizes transmission performance when towing. It does this by changing the shift points of your transmission in order to provide more power and torque at lower speeds.

This can be especially helpful when starting from a standing stop or climbing an incline with a heavy load behind you. Tow haul mode allows your vehicle to shift earlier and deliver more power sooner, allowing you to get up inclines faster and with less effort from your engine.

Finally, tow haul mode can also improve fuel economy by allowing your vehicle to shift at lower RPMs and reduce overall strain on your engine. By shifting at lower RPMs, your engine does not have to work as hard which in turn reduces fuel consumption significantly. This can save you money in the long run by reducing how often you need to fill up your tank with gas or diesel fuel.

Conclusion:

Tow haul mode is a great feature found on many modern trucks and SUVs which provides a number of benefits for drivers who are hauling heavy loads or trailers behind them. When engaged, tow haul mode increases engine braking, optimizes transmission performance while towing, and improves fuel efficiency all at once – making it an invaluable tool for any driver who needs increased performance while hauling cargo or trailers behind them.
