Fuel and Emissions System Description - 3-Mode Drive System

3-Mode Drive System

The 3-mode drive system consists of Normal mode, ECON mode, and Sport mode. The mode is changed by pressing one of the three mode buttons on the left side of the instrument panel.

Ambient Meter

The ambient meter is the ring of color around the speedometer. In Normal or ECON mode, it changes color based on data the ECM/PCM receives from various control units and sensors. The ECM/PCM calculates this data, forms an Eco drive profile, and then sends the profile to the gauge control module via F-CAN. When the gauge control module receives the Eco drive profile data, it responds by changing the background color of the speedometer. During low fuel economy, the ambient meter is blue; at medium fuel economy, the meter is blue-green; and at high fuel economy, it's green.
In Sport mode, the ambient meter color is red at all times, and the shift indicator lamp (SIL) stays off (M/T).

Normal Mode, ECON Mode





Sport Mode





Normal Mode, ECON Mode, and Sport Mode

Normal mode: This mode is a balance between driving performance and fuel economy. When you start the engine, the vehicle is in Normal mode. ECON mode: This mode provides the best fuel economy. If the accelerator is pressed quickly, the ETCS (electronic throttle control system) keeps the throttle response steady and smooth. Sport mode: This mode offers increased accelerator response.






Conditions In ECON Mode

- Cruise control: To decrease fuel use when cruise control is on in ECON mode, the cruise acceleration and cruise speed responses are milder than normal. When the vehicle speed is reduced by extra load conditions, cruise control assumes its normal response to maintain vehicle speed.
- IMA (Integrated Motor Assist): In ECON mode, the conditions for auto idle stop are expanded, regenerative braking during deceleration is increased, and power to the IPU (intelligent power unit) fan is increased.
- Air conditioning: To decrease fuel use in ECON mode, the A/C switches to recirculation mode and the compressor operates less frequently.
