Fuel Economy Mode
The vehicle may have a fuel economy mode. When engaged, fuel economy mode can improve the vehicle's fuel economy.

Pressing the eco button by the shift lever will engage fuel economy mode. When activated, the eco light in the instrument cluster will come on. See Fuel Economy Light. Pressing the button a second time will turn fuel economy mode off.
When fuel economy mode is on:
- The transmission will upshift sooner, and downshift later.
- The torque converter will lock up sooner, and stay on longer.
- The gas pedal will be less sensitive.
- The vehicle's computers will more aggressively shut off fuel to the engine
under deceleration.
- The engine operates at lower rpm's in fuel economy mode, which can increase
noise and vibration. This is normal.
