FUEL SAVER TECHNOLOGY 5.7L ENGINES
ONLY — IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:
This system may take some time to return to full
functionality after a battery disconnect.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function, included with eTorque
equipped vehicles, is developed to save fuel and
reduce emissions. The system will stop the engine
automatically as the vehicle decelerates at low
speeds if the required conditions are met.
Releasing the brake pedal or shifting out of DRIVE
will automatically restart the engine.
Vehicles equipped with eTorque contain a
heavy-duty motor generator and an additional
hybrid electric battery to store energy from vehicle
deceleration used to expand engine off energy
storage and for engine startup after a stop, as well
as providing engine torque assist when conditions
are met to enable this.
