Frequently Asked Questions
AnswerQuestion
The high voltage battery is electrically isolated from the rest of the
vehicle when the key is off. When you turn the key to on, high voltage
contactors inside the battery are closed to make the electricity avail-
able 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.
What are the series of clicks from the cargo area when I first turn the
key in the ignition?
The vehicle's computer will determine if an engine start is required
at key-on. Silent key start will start the engine if it is necessary for
cabin heating, windshield defrost, or if the outside temperature is low.
Why does the engine sometimes start at key-on?
There are several reasons the engine stays on for an extended amount
of time when you first start it. 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 it take a long time before the engine shuts down?
The engine is required to turn on above this speed to protect the
transmission hardware.
Why does my engine never shut down above 85 mph (137 km/h)?
