Question Answer
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 transaxle technology that help maximize your
hybrid’s fuel economy.
What does it
mean when my
power assist
gauge moves to
the right? To the
left?
Electricity is coming out of the battery when the
gauge moves to the right. Electricity is going into
the battery when the gauge moves to the left.
What is the fan
noise I hear from
the rear of my
hybrid?
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.
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.
