A vehicle climate control system includes a heat exchanger to heat ambient air using engine waste heat, and a plurality of positive temperature coefficient (PTC) heating elements to heat air passed through the heat exchanger. The vehicle also includes a controller programmed to, while the vehicle is driven without engine propulsion, issue a command to sequentially de-energize the PTC heating elements before an upcoming engine activation. The sequential de-energization of the PTC heating elements is performed according to a schedule that is based upon a power surge dissipation time.
