Lincoln Aviator: Hybrid Vehicle Operation / Braking
Your hybrid is equipped with standard
hydraulic braking and regenerative braking.
Regenerative braking is performed by your
transmission and it captures brake energy
and stores it in the high voltage battery.
You may also notice during extending
downhill driving that your engine continues
to run instead of shutting off. During this
engine braking, the engine stays on, but it is
not using any fuel. You may also hear a slight
whine or whistle when operating your
vehicle. This is the normal operation of the
electric motor in the hybrid system.
Transmission Operation
The engine and electric motor together
propel the vehicle through the automatic
transmission. This is normal hybrid operating
and helps deliver fuel efficiency and
performance...
Note: Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode...
