2010 GMC Terrain: The Feel Good Button
May 03, 2010
According the Terrain's owner's manual, pushing the ECO button does the following:
- Makes the transmission upshift sooner.
- Makes the throttle less sensitive.
- Locks the torque converter sooner and unlocks it later.
- Reduces fuel to the engine during deceleration.
- Lowers the engine's idle speed.
- Reduces performance.
But isn't it really there just to make you feel better?
