Low engine oil pressure in cars may be caused by the following reasons: 1. Insufficient oil level; 2. Metal debris in the oil clogging the oil pump screen, oil filter, or oil passages; 3. Use of inappropriate oil grade or deteriorated oil; 4. Faulty oil pressure sensor causing false low-pressure warnings. Maintaining proper engine oil pressure is essential for ensuring adequate lubrication between engine friction components. Under normal conditions, oil pressure should not be lower than 50 kPa at idle speed, and should remain between 200 to 300 kPa at medium to high speeds.

Do you need to press the AC button when using the air conditioner in summer?

In summer, you need to press the AC button when using the air conditioner, as the AC button is the cooling switch for the car's air conditioning system. When the AC button is turned on, the engine drives the air conditioning compressor to work. The compressor cools the hot air from outside, allowing cool air to blow out from the vents. Additionally, since the engine has to power the air conditioning compressor when AC is on, the engine's load increases, leading to higher fuel consumption. If the AC button is not pressed in summer, the hot air from outside will not be cooled by the compressor and will blow in at a high temperature, failing to achieve the cooling effect. Instead, it will make the interior feel hotter.

Is it necessary to buy a steering wheel cover for a car?

It is unnecessary to buy a steering wheel cover for a car, as the cover can cause irreparable damage to the leather steering wheel and may lead to slipping during driving, making it difficult to maintain a firm grip. The working principle of the steering wheel is to convert the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Precautions for using the steering wheel include: 1. Do not remove both hands from the steering wheel simultaneously; 2. Avoid placing your hands too close together on the steering wheel; 3. The turning amplitude and speed of the steering wheel should match the angle of the car's turn and the vehicle's speed; 4. Do not grip the steering wheel from the inside; 5. Avoid turning the steering wheel when the car is stationary to prevent damage to the steering system and tire wear.

What is the suitable tire pressure for frequent highway driving?

For frequent highway driving, it is better to have the tire pressure slightly higher than the standard value, which is 2.3 bar. Tire pressure should also vary with different seasons. In summer, the front tires should be 2.3 kg, and the rear tires should be 2.5 kg; in winter, the front tires should be 2.5 kg, and the rear tires should be 2.7 kg. For regular driving, maintaining a tire pressure of 2.5 kg is sufficient. Different types of tires have different standard values, and specific details can be found on the inside of the fuel tank cap. Proper tire pressure can effectively extend the lifespan of the tires while ensuring driving comfort. If you feel the car is bumpy during driving, check the tire pressure promptly.

Where is the first aid kit located in the Audi Q5?

The first aid kit in the Audi Q5 is located in the trunk. The kit contains emergency supplies such as gauze, medical cotton swabs, gloves, adhesive tape, bandages, as well as a warning triangle and tools for tire removal. Typically, only high-end vehicles are equipped with a first aid kit, while ordinary cars do not include one. The first aid kit is usually placed in the trunk or inside the spare tire compartment. Vehicle first aid products are categorized into first aid kits and first aid boxes. Some countries have emergency headrests designed for cars, which also fall under the category of vehicle first aid kits. Additionally, there are vehicle emergency kits, which cover a broader range of supplies. If a vehicle does not come with a first aid kit, it is advisable to purchase the necessary items separately.
