Automatic Engine Grade Braking
Automatic Engine Grade Braking assists when driving on a downhill grade. It maintains vehicle speed by automatically implementing a shift schedule that uses the engine and the transmission to slow the vehicle.
The system will automatically command downshifts to reduce vehicle speed, until the brake pedal is no longer being pressed.
While in the Electronic Range Select (ERS) mode, grade braking is deactivated, allowing the driver to select a range and limiting the highest gear available. Grade braking is available for normal driving and in Tow/Haul mode.
See Automatic Transmission on page 9‑23.
