To use the car's internal and external circulation functions, follow these steps: 1. Start the vehicle to activate the air conditioner for cooling or heating. 2. Simply adjust the control knob, and the display will show the temperature while activating the circulation function. 3. Turn on the A/C switch to operate the blower. 4. Rotate the knob—typically, the left side (marked in blue) is for cooling, and the right side (marked in red) is for heating; choose according to the weather. 5. Adjust the air circulation mode: use internal circulation for cooling and external circulation for ventilation.

What is the trick to never stalling when starting on a slope?

The trick to never stalling when starting on a slope is: 1. After engaging first gear, first apply throttle by pressing the accelerator until the tachometer reads 1500 to 2000 RPM, then keep your right foot steady; 2. Slowly release the clutch to the semi-engagement point, then press it back slightly—just before reaching the actual semi-engagement point—and keep your left foot steady while quickly releasing the handbrake; 3. As you release the handbrake, if you notice the car starting to roll backward, gently release the clutch with your left foot while maintaining the throttle at 1500 to 2000 RPM. Key points to remember when starting on a slope: Do not lift the clutch while pressing the accelerator, and lift the clutch slowly—doing it too quickly can cause the engine to stall.

What is the warranty period for a repaired accident vehicle?

Different types of vehicles and varying degrees of repairs will result in different warranty periods. For passenger vehicles, the quality assurance period for complete vehicle repairs or assembly repairs is 20,000 kilometers or 120 days. For secondary maintenance, the quality assurance period is 6,000 kilometers or 35 days. For primary maintenance, minor repairs, and parts repairs, the quality assurance period is 2,000 kilometers or 10 days. Below is additional information: 1. Accident vehicle: Refers to a vehicle that has been damaged due to non-natural wear and tear, resulting in decreased mechanical performance and economic value. Accident vehicles generally refer to vehicles with structural damage. Flood-damaged cars and fire-damaged cars also fall under the category of 'special accident vehicles.' 2. Methods to identify an accident vehicle: Exterior inspection, light inspection, insurance record check, and interior inspection.

Where to Check the Production Date of Tires?

The production date of tires can be found on the outer sidewall of the tire. It is a series of alphanumeric characters starting with "DOT," which stands for the certification by the U.S. Department of Transportation. The following numbers and letters represent the tire's origin information and factory code, while the last four digits indicate the production date. In addition to the production date, the tire sidewall also displays the tire width, aspect ratio, tire type, rim diameter, load index, and speed rating. Tires typically have a shelf life of 4 to 5 years. When purchasing, pay attention to the production date and try to avoid tires that have been stored for more than 3 years. Since tires are made of rubber, they can deteriorate over time, leading to reduced performance. If cracks appear, there is a higher risk of tire blowouts, which can compromise driving safety.

How many days can a new car be driven on the road with an invoice?

New cars cannot be driven on the road with an invoice. According to Article 8 of the Road Traffic Safety Law of the People's Republic of China, the state implements a registration system for motor vehicles. Motor vehicles can only be driven on the road after being registered by the traffic management department of the public security authority. For motor vehicles that have not yet been registered but need to be temporarily driven on the road, a temporary license plate must be obtained. When driving a motor vehicle on the road, the vehicle must display the license plate, place the inspection qualification mark and insurance mark, and carry the vehicle registration certificate. An invoice is a business document issued and received by all units and individuals in the purchase and sale of goods, provision or acceptance of services, and other business activities, serving as the original basis for accounting.

Is it safe to drive with a tire pressure of 2.1?

A tire pressure of 2.1 is not safe for normal driving. The recommended tire pressure range is between 2.3 and 2.5. Excessively low tire pressure can cause severe deformation of the tire sidewall, damage the cord layer, and lead to a blowout. Tire pressure refers to the air pressure inside the tire. The hazards of low tire pressure include: 1. Increased friction coefficient with the road surface, leading to higher fuel consumption; 2. Making the steering wheel heavy, which is a safety hazard; 3. Increasing the movement of various parts of the tire, causing abnormal heat due to excessive rolling and accelerating rubber aging; 4. Reducing the functionality of the cord and rubber; 5. Making the tire sidewall prone to cracks and causing flexing movements.
