Hybrid vehicle

  • Be sure the shift lever is in P (Park). The vehicle starts only when the shift lever is in P (Park).
  • This vehicle does not have a regular 12V battery that needs periodic replacement. It is lithium ion polymer type integrated into the HEV high voltage battery.

After starting vehicle, operate the vehicle safely outdoors in ready mode stopped and/or drive it for 30 minutes total to charge the 12V battery fully.
