Electric Mode and Extended-Range Mode
The ELR is an electric vehicle with extended range capability. Plug it in, let it charge overnight, and it’s ready to run on a pure \
electric charge — gas- and tailpipe emissions-free. After that, the ELR uses a range-extending gas engine that produces enough energy to power it for hundreds of miles on a single tank of gas.
Electric Mode
In Electric Mode, the ELR will not use gasoline or produce tailpipe emissions. During this primary mode, the ELR is powered by
electrical energy stored in its high voltage propulsion battery. It can operate in this mode until the battery is depleted to a prede-termined level.
Electric range is affected by colder outside temperatures. During colder months, the energy needed to warm the vehicle’s cabin and high voltage propulsion battery can cause the vehicle’s elec-tric range to decline. See Driving for Better Energy Efficiency in the Driving and Operating section of your Owner Manual.
Extended-Range Mode
Once the electric charge is depleted, the range-extending gas engine will start to generate enough power to continue driving the vehicle. Engine operation ensures that you will not be stranded by a depleted battery. The vehicle determines when the engine
needs to run. Engine speed will vary, depending on driving
conditions, to optimize efficiency. The engine will not fully charge the high voltage propulsion battery. The vehicle must be plugged in to recharge.
Total Vehicle Range
Total vehicle range is based on the available combined electric and extended range. The displayed electric and fuel ranges are
projections based on past vehicle performance and charge/fuel level. The displayed ranges will change based on driving style, outside temperature and climate settings.
