What should I do if the vehicle runs out of fuel and the high voltage battery is out of charge?
  • Refuel and start your vehicle normally. The engine will recharge the high voltage battery.
Why does the engine sometimes start at key-on?
  • The vehicle's computer determines if an engine start is required at key-on. It starts the engine when necessary for cabin heating, windshield defrost, if the high voltage battery is low, or if the outside temperature is low.
Can I put E15 or E85 in my vehicle, and how will it affect my fuel economy?
  • Your hybrid vehicle can use E15 (15% ethanol, 85% gasoline) fuel, but you may notice slightly reduced fuel economy because ethanol contains less energy per gallon than gasoline. Your hybrid vehicle is not designed to use E85 (85% ethanol).
Why does it take a long time before the engine shuts down?
  • There are several reasons the engine stays on for an extended amount of time when you first start it. One common reason is to make sure that the emissions components are warm enough to minimize tailpipe emission. As the climate gets cooler, the engine-on time is extended.
Why does my engine stay on when it is extremely cold outside?
  • In order to make sure that the climate control system can begin heating the cabin or defrosting the windshield as soon as a driver requests it, the engine coolant temperature has to be kept sufficiently hot. Keeping the engine on is required to maintain the correct coolant temperature.
