Cadillac 2016 ELR Convenience/Personalization Manual page 6

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 predeter-
mined level.
Electric range is affected by climate and driving style. In hot
or cold climates, the energy needed to cool or warm the vehicle's
cabin and high voltage propulsion battery can cause the vehicle's
electric range to decline. See Driving for Better Energy Efficiency
in the In Brief 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

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.
