Hybrid Electric Vehicle Information – Frequently Asked Questions
What is the service life of the high-voltage battery system?
The high-voltage battery system is designed to last for the life of your vehicle.
Does the high-voltage battery require maintenance?
The high-voltage battery does not require maintenance.
What should I do if the vehicle runs out of fuel and the high-voltage battery is discharged?
Refuel and start the vehicle normally. The engine will recharge the high-voltage battery.
Why does the engine sometimes start when the ignition is switched on?
The vehicle computer determines if engine start is required when the ignition is switched on. It starts the engine when necessary to heat the cabin, defrost the windshield, or if the outside air temperature is low.
Can I use E15 or E85 in my vehicle, and how will it affect fuel economy?
Your hybrid vehicle can use E15 (15% ethanol, 85% gasoline) fuel, but you may notice a slight decrease in fuel economy because ethanol contains less energy per gallon than gasoline. Your hybrid vehicle is not designed to use E85 (85% ethanol).
Why does the engine take a long time to shut off?
There are several reasons why the engine remains running for a long time when you first start it. One common reason is to make sure the emission components are warm enough to minimize tailpipe emissions. As the climate becomes cooler, engine running time increases.
Why does my engine run when it is very cold outside?
To make sure the climate control system can begin heating the cabin or defrosting the windshield as soon as the driver requests it, the engine coolant temperature must be maintained sufficiently warm. Keeping the engine running is required to maintain the correct engine coolant temperature.
