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 required at key-on. Silent Key
Start (SKS) will start the engine if it is
necessary for cabin heating, windshield defrost,
or if the outside temperature is low.
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 47 mph
(75 km/h)?
The engine is required to turn on above this
speed to protect the transmission hardware.
