Answer
The fan noise comes from two fans
located inside the high voltage
battery. These fans turn on when
the battery requires cooling air.
The fan speed, and associated
noise level, will change according
to both the amount of cooling
required and the speed of the
vehicle to maintain good
performance.
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.
The engine oil should be changed
every 10,000 miles (16,000 km)
under normal operating conditions.
See the Scheduled Maintenance
Guide chapter.
Your hybrid vehicle can use E10
(10% ethanol, 90% 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).
The high voltage battery system is
designed to last the life of the
vehicle and requires no
maintenance.
