GMC Terrain: Automatic Transmission / Tow/Haul Mode
For information on the Tow/Haul Mode, see Driver Mode Control.
Automatic Engine Grade Braking
Automatic Engine Grade Braking assists when driving downhill. It maintains vehicle speed by automatically implementing a shift pattern that uses the engine and the transmission to slow the vehicle. The system will automatically command downshifts to reduce vehicle speed. The normal shift pattern will return once the vehicle is on a low grade or when the accelerator pedal is 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.
