Your Chevrolet Tahoe may be equipped with a feature that improves vehicle acceleration on snow and ice covered roads.
When active, Snow/Ice Mode on Tahoe will adjust acceleration to optimize traction on slippery surfaces. This can compromise the acceleration on dry asphalt.
The Snow/Ice Mode can be activated by rotating the Driver Mode Control (DMC) rotary knob on the instrument panel to the left of the steering wheel.
Rotate the Driver Mode Control knob until Snow/Ice is highlighted in the instrument cluster.
The Snow/Ice Mode will activate within a few seconds and its symbol will illuminate at the bottom right corner of the screen.
Note: This feature is not intended for use when the vehicle is stuck in sand, mud, ice, snow, or gravel.
