How to Turn on the Heater in a BMW 5 Series?

[DeRafael]

To turn on the heater in a BMW 5 Series, you don't need to activate the air conditioning. Simply press the air blower button and then increase the temperature. There are a few things to keep in mind when using the car heater: 1. Avoid directing the warm air straight at your head, as prolonged exposure can cause driver fatigue and affect driving safety. It's recommended to crack open a window slightly when using the heater for extended periods to ensure proper air circulation and maintain oxygen levels in the car, keeping the driver alert. 2. Some car owners tend to rest in their vehicles, but it's crucial not to keep the heater running while sleeping in the car, as this can easily lead to carbon monoxide poisoning. 3. When the heater is on, the car becomes an enclosed space, creating an ideal environment for bacteria to grow and spread. If someone smokes in the car, the amine and nicotine from the smoke can adhere to the surface of the evaporator. If the air conditioning is not used frequently or during rainy weather, bacteria can proliferate on the evaporator surface, causing air pollution inside the car when the air conditioning is turned on again.
