Question Answer
Why does my engine
never shut down above
45 mph (73 km/h)?
The engine is required to turn on above
this speed to protect the transmission
hardware.
Why does my engine stay
ON when it’s extremely
cold outside?
In order to ensure that the climate control
system can begin heating the cabin and/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 minimum temperature.
Why does my engine rev
up so high sometimes
when I accelerate?
Your vehicle’s engine and transmission are
designed to deliver the power you need at
the most efficient engine speed. This may
be higher than expected during heavy
accelerations, and may fluctuate during
steady state driving. These are
characteristics of the Atkinson engine cycle
and the eCVT transmission technology that
help maximize your hybrid’s fuel economy.
What is the fan noise I
hear from the rear of my
hybrid?
The fan noise comes from a fan located
inside the high voltage battery. This fan
turns on when the battery requires cooling
air. The fan speed, and associated noise
level, will change according to the amount
of cooling required to maintain good
performance. Maintaining the battery
temperature at optimal conditions also
prolongs the useful life of the battery and
helps to achieve better fuel economy.
HowfarcanIgoin
Electric Drive if I run out
of gas?
Running out of gas is not recommended.
However, you may be able to go about one
mile, driving at 30 mph (48 km/h), if the
battery has a normal state of charge.
