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.

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.
