Frequently asked questions
Question
What are the series of
clicks from the cargo area
when I first turn the key in
the ignition?
Why does the engine
sometimes start at key-on?
Answer
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.
The vehicle's computer will determine if
an engine start if it is necessary for cabin
heating or windshield defrost. The engine
will also be started when ambient
temperatures are low.
