Frequently asked questions
Question Answer
What are the
series of clicks
from the cargo
area when I first
turn the key in
the ignition?
The high voltage battery is electrically isolated from
the rest of the vehicle when the key is off. When
the key is turned to on, high voltage contactors
inside the battery are closed to make the electricity
available to the motor/generator and enable the
vehicle to drive. The clicks are the sound of these
contactors as they close and open during start up
and shut down.
Why does the
engine
sometimes start
at key-on?
The vehicle’s computer will determine if an engine
start is necessary for cabin heating or windshield
defrost. The engine will also be started when
ambient temperatures are low.
After I start my
car in the
morning, why
does it take a
long time before
the engine shuts
down?
There are several reasons the engine stays on for an
extended amount of time when it is first started.
One common reason is to ensure that the emissions
components are warm enough to minimize tailpipe
emissions. As the climate gets cooler, this
“engine-ON” time is extended.
Why does my
engine never
shut down above
40 mph
(65 km/h)?
The engine is required to turn on above this speed
to protect the transaxle hardware.
