Your vehicle will return the regenerative braking feature once the battery is warmed or has enough room to store energy. Drivers cannot "turn on" regenerative braking, however they can direct the vehicle to apply the brake pedal to decelerate in a more predictable manner (closer to what regenerative braking feels like). Select Controls>Pedals & Steering> Apply Brakes When Regenerative Braking is Limited. Prevent the temporary loss of regenerative braking (or limited deceleration) by preconditioning your battery and never charging to 95% or higher.
