How Long Is It Appropriate to Run the Air Conditioner While Parked?

What is the reason why the car air conditioner only has wind at the 4th speed?

The reason why the car heater switch only has wind at the fourth speed is due to the burnout of the heater blower speed control resistor. Specific information is as follows: 1. The solution is to promptly go to the car's 4S shop or repair shop to replace the heater blower speed control resistor, which can solve the problem of the car heater's air outlet failure. 2. Automatic air conditioning and manual air conditioning: Both automatic and manual car air conditioners are similar when turning on the heater. They both adjust the temperature by rotating the temperature control button, with the red area indicating an increase in temperature. However, the automatic air conditioner can set a specific temperature, and it will automatically adjust based on the temperature inside the car. Some car owners, afraid of the cold, turn on the heater immediately after starting the vehicle, thinking it will quickly raise the interior temperature, but this method is actually not effective.

What is the appropriate tire pressure for Nissan Sunny?

The standard tire pressure for Nissan Sunny is 2.4-2.5 bar. Tire pressure may vary depending on different brands and models. Factors such as seasons and load conditions also affect it. The specific recommended pressure can usually be found on the fuel tank cap, the side of the driver's door, or in the user manual. Tire pressure is an indicator of a vehicle's load capacity. The load capacity of a car depends on the tire pressure. According to the relationship between the tire load index, tire pressure, and load capacity, higher tire pressure increases load capacity, while lower pressure reduces it. Generally, the lower limit of the standard tire pressure is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. When a car is driving at a constant speed on a level road, it must overcome rolling resistance from the ground and air resistance. Tire pressure significantly affects the rolling resistance coefficient. When the pressure decreases, the rolling resistance coefficient increases rapidly because lower tire pressure causes greater tire deformation and increased hysteresis loss. Therefore, proper tire pressure ensures good vehicle performance.

Can Diesel No. 0 and -35 Be Mixed?

Mixing half No. -35 diesel and half No. 0 diesel is acceptable. The diesel grade is merely an indicator of the fuel's resistance to congealing. The smaller the number in the diesel grade, the stronger its resistance to congealing. However, the diesel grade cannot be used as a basis for judging fuel quality. The anti-freezing capability of a mixture of half No. -35 diesel and half No. 0 diesel is certainly not as strong as that of pure No. -35 diesel. Therefore, when refueling, it is advisable to choose based on the actual local temperature. Below is an introduction to diesel usage: No. 5 diesel is suitable for use at temperatures above 8°C; No. 0 diesel is suitable for use at temperatures between 8°C and 4°C; No. -10 diesel is suitable for use at temperatures between 4°C and -5°C; No. -20 diesel is suitable for use at temperatures between -5°C and -14°C; No. -35 diesel is suitable for use at temperatures between -14°C and -29°C; No. -50 diesel is suitable for use at temperatures between -29°C and -44°C or below.

What is the solution for the abnormal noise in the classic Focus?

For the abnormal noise in the classic Focus, you can try purchasing new half-shaft bearing bases and brackets, bearings, and oil seals for installation. Below is more information about the Focus: 1. Focus RS: The Focus RS is a new generation of high-performance sedan developed based on the revamped European version of the Focus. The all-new Ford Focus RS will exclusively feature Michelin tires. Among them, the Michelin Pilot Super Sport (specification 235/35/19) is its standard tire, while the Michelin Pilot Sport Cup 2 (specification 235/35/19), known for its outstanding track performance, is available as an optional tire. 2. Focus RS engine: The massive intercooler intake vents of the Focus RS run from the top of the bumper down to the front lip, adorned with black metal mesh. The fog lights are directly embedded at the front of the front fenders without any additional decoration. Two additional heat dissipation vents are added on the engine hood, and the heat dissipation vents at the rear of the front fenders suggest the car will have a powerful braking system.

How to Restart After Replacing Car Key Battery?

To restart after replacing the car key battery, first start the vehicle's engine and activate the entire electronic system. Then, press and hold the lock button on the driver's side door for more than 5 seconds without releasing. The car's remote control will then complete the matching process. Below is an introduction to car keys: 1. Introduction: A car key is a tool used to switch the car on and off. Modern car keys use a chip system, which is a magnetic chip system. The car's ignition lock cylinder's reading coil will read the key's chip; each chip has fixed digital information. 2. Categories: A remote key allows you to unlock and lock the car from a distance without inserting the key into the lock. 3. Advantages: The biggest advantage is that, regardless of day or night, you do not need to locate the lock hole and can conveniently unlock and lock the car from a distance. A weak radio wave is emitted from the owner's vicinity, received by the car's antenna, and the signal code is identified by the electronic control unit (ECU). The system's actuator (motor or electromagnetic coil) then performs the lock/unlock action. The system mainly consists of two parts: a transmitter and a receiver.

What to do if ETC is deducted without reason?

Methods to deal with ETC being deducted without reason: 1. Go to the bank where the ETC service was processed. You need to bring the original and photocopy of the vehicle owner's valid ID card and driving license (if it is not the owner, the agent's valid ID card is also required) and the photocopy of the driving license with the page stamped with the last annual inspection seal; 2. Fill out an application form for a refund, requesting the bank to check the account and confirm the situation of being mistakenly charged; 3. After verification by the bank, the overcharged fees can be refunded. Precautions for using ETC include: 1. The ETC transaction sensing area is 8 meters. To prevent the ETC device failure of the vehicle in front, keep a distance of more than 10 meters from the vehicle in front; 2. The recognition speed for ETC lane passage is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, which will lead to charging failure; 3. When using a debit card to bind ETC, insufficient balance will also lead to charging failure.
