Question
Answer
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.
How far can I go in 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.
What is the engine oil change
service interval?
The engine oil should be changed
every 10,000 miles (16,000 km)
under normal operating conditions.
See the
Scheduled Maintenance
Guide
chapter.
Can I put E10 or E85 in my
vehicle, and how will it affect my
fuel economy?
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).
