Starting USING THE ENGINE BLOCK HEATER (IF EQUIPPED) An engine block heater warms the engine coolant, which improves starting, warms up the engine faster and allows the heaterĆdefroster system to respond quickly. It is strongly recommended if you live in a region where temperatures reach -23ºC (-10ºF) or below. For best results, plug the heater in at least three hours before starting the vehicle. Using the heater for more than three hours will not harm the engine, so the heater can be plugged in the night before starting the vehicle. To prevent electrical shock, do not use your heater with ungrounded electrical systems or twoĆpronged (cheater) adapters. 144
