AnswerQuestion
The engine is required to turn on above this
speed to protect the transmission hard-
ware.
Why does my engine never shut down
above 85 mph (137 km/h)
In order to make sure that the climate
control system can begin heating the cabin
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 main-
tain the correct coolant temperature.
Why does my engine stay on when it is
extremely cold outside?
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 when
driving at a steady speed. These are charac-
teristics of the Atkinson engine cycle and
the transmission technology that help
maximize your hybrid's fuel economy.
Why does my engine rev up so high some-
times when I accelerate?
The fan noise comes from a fan located
next to the high voltage battery pack. 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.
What is the fan noise I hear from the rear
of my hybrid?
Change the engine oil every 10,000 mi
(16,000 km) or once per year under normal
operating conditions.
What is the engine oil change service
interval?
Your hybrid vehicle can use E15 (15%
ethanol, 85% gasoline) fuel, but you may
notice slightly reduced fuel economy
because ethanol contains less energy per
gallon than gasoline. Your hybrid vehicle is
not designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and how
will it affect my fuel economy?
The high voltage battery system is designed
to last the life of the vehicle and requires
no maintenance.
How long will my high voltage battery last?
Does it need maintenance?
