an electric machine;
a traction battery selectively connected to the electric machine;
a human-machine interface (HMI); and
a controller programmed to, after receiving a signal from the HMI enabling towed vehicle operation of the electrified vehicle, control the electric machine to generate a regenerative braking torque in response to deceleration of the electrified vehicle exceeding an associated deceleration threshold and road grade being below a road grade threshold.
