How often should the air conditioning in a new car be recharged with refrigerant?

There is no fixed interval for recharging the refrigerant in a car's air conditioning system. The need for recharge is primarily determined by the effectiveness of the cooling. Precautions for refrigerant recharge: When the refrigerant (Freon) in the cooling system decreases due to leakage, leading to a significant drop in cooling efficiency, it is necessary to replenish or replace the refrigerant. Before replenishing, the cause of the refrigerant leakage must be identified and repaired. Otherwise, the newly added refrigerant will leak again. Precautions for using car air conditioning: Car air conditioning systems are generally unused during winter. Before initial startup, check the belt tension. After prolonged use, the system should undergo dust and bacteria removal. Observe the engine coolant temperature after running the air conditioning for a while. If the temperature rises abnormally, stop the air conditioning immediately. Methods for car air conditioning maintenance: Regularly check the refrigerant and compressor oil, adjust the low-pressure side pressure to 2-3 bar and the high-pressure side pressure to 15-25 bar, clean the condenser, and wash the evaporator surface.

Is the Landwind X7 still being sold?

The currently available models are all 1.5T versions, and they are still being sold. In the design patent lawsuit between Jaguar Land Rover and Jiangling Holdings, Jaguar Land Rover ultimately prevailed. This patent lawsuit was triggered by the Landwind X7's "borrowing" from the Land Rover Evoque, resulting in an overly similar appearance. December 21, 2010: The Land Rover Range Rover Evoque model was publicly exhibited at the Guangzhou International Auto Show; November 28, 2018: The Patent Reexamination Board and Land Rover appealed to the Beijing High People's Court. In the final judgment, the court revoked the ruling made by the Beijing Intellectual Property Court on the grounds that "the aforementioned improvements did not make the overall visual effect of this patent significantly different from the comparative design." March 22, 2019: The Chaoyang District Court in Beijing ruled that all sales, manufacturing, and marketing of the Landwind X7 must cease immediately, and compensation must be paid to Jaguar Land Rover. Due to a nearly one-month delay in uploading the electronic version of the court's judgment documents, the specific details of the ruling are not yet known. However, since both Landwind and Land Rover's design patents were invalidated, the judgment may have been based on relevant provisions of the Anti-Unfair Competition Law.

Are Car Sunshades Useful?

Sunshades have both advantages and disadvantages, and can be chosen based on needs. Advantages of sunshades: Protect the dashboard from damage such as cracking and aging caused by direct sunlight exposure, while also reducing the interior temperature, indirectly improving the effectiveness of the car's air conditioning; during the day, they prevent reflection and reduce sunlight refraction on the windshield that can create glare, ensuring clear driving visibility; at night, they minimize light refraction, reducing blind spots caused by roadside lights reflecting off the dashboard onto the windshield. Disadvantages of sunshades: The dashboard is a high-temperature area that requires better heat dissipation. Using multiple covers in the summer when interior temperatures are already high can impede heat dissipation. When wind blows onto the dashboard, dust trapped in the sunshade can flow back with the wind directly into the faces of front-seat occupants. Precautions for using sunshades: Some dashboards are made of soft plastic, and using sunshades with poor-quality adhesive strips may cause corrosion. Always purchase genuine sunshades or opt for non-adhesive sunshades with good anti-slip effects; choose vehicle-specific sunshades and ensure they leave necessary gaps to avoid interfering with safety features like airbags; if a sunshade emits odors after prolonged sun exposure, it may be a substandard product and should be replaced immediately.

Is It Necessary to Install Sealing Strips on a New Car?

It is necessary to install sealing strips on a new car. The door sealing strip is a product that seals the door, making it harder to open, and serves functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Functions of Door Sealing Strips: Door sealing strips (auto-door-rubber-seal-strip) are mainly used for fixing, dust prevention, and sealing of car doors. They feature good elasticity, resistance to compression deformation, aging, ozone, and chemical effects. Equipped with unique metal clamps and tongue-shaped buckles, they are sturdy, durable, and easy to install. Primarily applied on door panels, door frames, side windows, front and rear windshields, engine hoods, and trunk lids, they serve functions such as waterproofing, dust prevention, sound insulation, temperature insulation, shock absorption, and decoration. Fuel-Saving Tips During the New Car Break-In Period: Avoid driving with excessive load during the break-in period of a new car; the lighter the body, the better, as heavy loads can cause damage to the car. Do not let the engine rev too high; generally, keep the RPM below 3,000, or below 3,500 for automatic transmissions. Avoid maintaining a single gear for too long or driving at low speeds for extended periods; gradually increase the speed instead.

Which direction do the wheels turn when steering left?

When moving forward, turning the steering wheel left makes the vehicle turn left; turning it right makes the vehicle turn right. When reversing, turning the steering wheel left makes the rear of the vehicle move left; turning it right makes the rear move right. For a forward-moving vehicle, turning the steering wheel left causes the vehicle to turn left. When reversing, turning the steering wheel left makes the front wheels turn right while the rear wheels remain unchanged, causing the vehicle to move backward to the left. Below are detailed instructions on steering: Requirements for steering: Beginner drivers should first sit upright and steady, adjust the seat properly, and grip the steering wheel firmly with both hands. Hold the steering wheel at the 9 o'clock and 3 o'clock positions, or slightly higher depending on personal preference. Steering techniques: When turning during driving, if turning left, the left hand should exert force while the right hand assists. When straightening, the right hand exerts force while the left hand assists. If turning right, the right hand exerts force while the left hand assists, and when straightening, the left hand exerts force while the right hand assists. When making a U-turn, always cross your hands while steering—avoid turning the wheel bit by bit (commonly known as "feeding the wheel"), as this can lead to confusion and loss of control in emergencies. Avoid turning the wheel while stationary or turning it to the full lock, as this can cause tire wear and increase stress on the vehicle's steering system.
