eAssist Overview (if equipped)
A compact electric assist system called eAssist has been integrated with the highly efficient 
2.4-liter four-cylinder engine and six-speed automatic transmission to provide an electric 
“boost” to help conserve fuel. eAssist includes a small, but powerful, electric motor rated at 
15 kilowatts. It replaces the typical alternator found on most engines. \
eAssist also uses a 
small, advanced 115-volt lithium-ion battery located in the trunk.
eAssist Features
Auto Start/Stop
While driving, when the brake is applied and the vehicle comes to a complete stop, the 
automatic engine start/stop system may turn off the engine, referred to \
as an Auto Stop. In 
Auto Stop mode, the tachometer gauge will read AUTO STOP. The audio syst\
em, climate 
controls and other accessories will be powered by the high-voltage battery. The engine will 
restart immediately when the brake pedal is released or the accelerator pedal is applied.
After parking the vehicle and turning off the engine, the tachometer gauge will read OFF.
There are several conditions that may cause the engine to remain running or restart when 
the vehicle is stopped.
• The engine, transmission or high-voltage battery is not at the required operating 
 temperature.
•  The outside temperature is less than –4º F (–20º C).
•  The shift lever is in any gear other than Drive (D).
•  The high-voltage battery state of charge is low. It will automatically recharge as the 
vehicle is driven.
•  The climate control system requires the engine to run based on the clima\
te control or 
defog setting. Using the eco Air Conditioning mode will result in more f\
requent and 
  longer Auto Stops than the Comfort Air Conditioning mode.
•  The Auto Stop time is greater than two minutes.
See Driving and Operating in your Owner Manual.
Power Flow Display
The Power Flow display, located on the infotainment system touch screen, indicates the 
current eAssist operating mode, energy flow direction and high voltage battery charge 
level. The operating modes include Engine Idle, Auto Stop, Engine Power,\
 Hybrid Power, 
and Regen Recovery.
