GMC Terrain: Automatic Transmission / Manual Mode
Electronic Range Select (ERS) Mode
ERS or manual mode allows for the selection of the range of gear positions. Use this mode when driving downhill or towing a trailer to limit the top gear and vehicle speed. The shift position indicator within the Driver Information Center (DIC) will display a number next to the L indicating the highest available gear under manual mode and the driving conditions when manual mode was selected.
To use this feature:
- With the vehicle in D (Drive), press the L (Low) button.
- Press the plus or minus button on the center stack to increase or decrease the gear range available.
When shifting to L (Low), the transmission will shift to a preset lower gear range. For this preset range, the highest gear available is displayed next to the L in the DIC. See Driver Information Center (DIC) (Base and Midlevel) or Driver Information Center (DIC) (Uplevel). All gears below that number are available to use. For example, when 4 (Fourth) is shown next to the L, 1 (First) through 4 (Fourth) gears are shifted automatically. To shift to 5 (Fifth) gear, press the + (Plus) button or shift into D (Drive).
L (Low) will prevent shifting to a lower gear range if the engine speed is too high. If vehicle speed is not reduced within the time allowed, the lower gear range shift will not be completed. Slow the vehicle, then press the − (Minus) button to the desired lower gear range.
While using ERS, cruise control can be used.
