Tow/Haul Mode

---

Tow/Haul mode (standard on all models) enhances performance while pulling a trailer or hauling heavy loads. When activated, this feature modifies the automatic transmission shift schedule and helps reduce throttle pedal activity by the driver while traveling over rolling terrain. A lighted icon on the instrument panel indicates when Tow/Haul mode has been activated. Silverado HD shown here with Tow/Haul mode and Tap-Up/Tap-Down driver shift control.
