Steps to turn on the heater in a Passat: 1. Start the car and wait for about 5 to 10 minutes until the engine coolant reaches normal operating temperature, then you can turn on the heater; 2. Adjust the air conditioning circulation mode to the internal circulation setting; 3. Switch the air conditioning mode to the heating mode; 4. Do not press the AC button as the heater utilizes the car's own heat cycle and does not require the air conditioning compressor; 5. Adjust the air conditioning gear to regulate the airflow direction. For manual air conditioning, turn the knob to the red zone and turn on the blower to get warm air. For automatic air conditioning, simply increase the temperature to the desired level and press the auto button. The dimensions of the Passat are 4933mm in length, 1836mm in width, and 469mm in height.

Turning on the heating in a Passat is actually quite simple. Let me explain step by step. After starting the vehicle, allow the engine to warm up first. In winter, wait until the coolant temperature gauge rises to the middle position before operating. For manual air conditioning, turn the temperature knob clockwise all the way to the red zone, then adjust the fan speed knob to let the warm air blow out. For automatic air conditioning, simply press the AUTO button and rotate the temperature control knob to increase it to your desired temperature. Remember to adjust the air vent direction to blow towards the feet and the front windshield, as this improves heating efficiency and reduces fogging. When you first turn on the heating, activating the recirculation mode can speed up warming. Once the interior is warm, switch to fresh air mode for ventilation. Avoid turning on the AC switch simultaneously, as this engages the cooling compressor, which can increase fuel consumption. If the windshield starts fogging up, press the defrost button immediately, and the heating system will prioritize defogging. Regularly checking the cabin air filter and coolant level also helps maintain stable heating performance.

What does the gear exclamation mark on the Ford Transit dashboard mean?
