Chevrolet Tahoe features Tow/Haul Mode which when enabled enhances the towing/hauling capability of the vehicle.
The Tow/Haul Mode on Tahoe adjusts the transmission shift pattern to reduce shift cycling. This provides increased performance, vehicle control, and enhanced transmission and engine cooling when driving down steep hills or mountain grades, when towing, or when hauling heavy loads.
The Tow/Haul Mode on Chevy Tahoe can be enabled using the Driver Mode Control (DMC) knob on the instrument panel to the left of the steering wheel.
Rotate the Driver Mode Control knob until Two/Haul is highlighted in the instrument cluster.
The Tow/Haul Mode will activate within a few seconds and its symbol will illuminate at the bottom right corner of the display.
You can turn off the Tow/Haul mode by rotating Driver Mode Control to Normal position. Keep in mind that Driver Mode defaults to Normal position every time you restart the engine.
Tow/Haul Mode Grade Braking
Tow/Haul Mode Grade Braking is only enabled on Chevy Tahoe while the Tow/Haul Mode is selected and the vehicle is not in the Range Selection Mode. Tow/Haul Mode Grade Braking assists in maintaining desired vehicle speeds when driving on downhill grades by using the engine and transmission to slow the vehicle.
