Introduction to the gear function buttons of the Tiguan L

The gear function buttons of the Tiguan L include P, N, R, and D/S. Below is a detailed introduction to each: 1. D: This is the drive gear. Follow the prompts to press the brake, hold the side button on the gear lever, and push the lever downward. 2. S: This is the sport gear, the most powerful gear. The shifting operation is the same as for the D gear. To disengage the S gear, simply pull the gear lever back again (no need to press the brake at this time). 3. N: This is the neutral gear. Use your thumb to press the side button and push the gear lever forward. 4. R: This is the reverse gear. Move the gear lever to the position marked with the letter R. 5. P: This is the parking gear. Press and hold the "P" button on the gear lever. 6. Manual mode: Shift the gear to "D" and then move the gear lever to the right in this position. Move the lever up to shift up and down to shift down.

What is the reason for no cooling at idle but normal operation when driving?

Check if the air conditioning system is malfunctioning. Here is relevant information: 1. Reasons for air conditioning not cooling: Lack of refrigerant, car air conditioning needs to be refilled with refrigerant every 2~3 years. Refrigerant loss is usually due to leakage. If the car air conditioning does not cool, but starts cooling after refilling the refrigerant, consider whether there is a lack of refrigerant. Damage to the air conditioning flap, a relatively common issue is damage to the air conditioning flap motor. If there is a problem with the flap motor, it is relatively more troublesome. The flap motor is generally located in the middle of the dashboard, serving as the main switch for the air conditioning vents. Even if the air conditioning can cool, cold air can only come out through gaps, significantly affecting the cooling effect. 2. Hazards of running air conditioning at idle: When idling with the air conditioning on, instead of focusing on the economic cost caused by fuel consumption, more attention should be paid to the damage to the car and the increased later costs. When the engine runs at low speed and idle for a long time, the piston valves are more prone to carbon deposits. Excessive carbon deposits will directly affect fuel economy and also impact the performance and even the lifespan of the engine.

Why does the AC automatically turn on when defrosting the front windshield?

The reason why the AC automatically turns on when defrosting the front windshield may be related to using warm air for defogging. Reasons for the AC automatically turning on: The AC refers to the air conditioning compressor, while the car's warm air is not provided by the compressor. Therefore, the AC does not operate when using warm air. In winter, when defogging with warm air, if the front windshield defogging function is activated simultaneously, the car's system will automatically engage the compressor. Some vehicle systems even have a memory function—if the warm air and front windshield defogging were used together previously, the system will remember this setting and automatically activate the compressor the next time warm air is turned on. Principle behind the AC automatically turning on: Window fogging occurs due to high humidity inside the car, where moisture in the air condenses on the windows when it meets cold surfaces. The car's warm air comes from the engine's heater core, and the air heated by the heater core tends to be warm and humid. To quickly defog the interior, dry air is needed. When the AC compressor operates, it has a dehumidifying effect—air cooled by the compressor becomes dry, and after being heated by the heater core, the air delivered into the cabin becomes both dry and warm. Blowing this dry, warm air onto the front windshield achieves better defogging results.

What are the car brands?

In terms of brands, cars can be divided into domestic cars, joint venture cars, and imported cars. BYD, Chery, and Hongqi are domestic cars. Volkswagen and Audi under FAW Group, and Peugeot and Honda under Dongfeng Motor Group are joint venture cars. BMW X3 and British Infiniti are imported cars. Japanese brands mainly include: Honda (Acura), Toyota (Lexus), Nissan (Infiniti), Mitsubishi, Suzuki, Mazda, etc. German brands include: Mercedes-Benz (Maybach and AMG divisions), BMW (Rolls-Royce and M divisions), and Volkswagen (Bentley, Lamborghini, Bugatti, Porsche, Audi, Skoda, SEAT, etc.). American brands mainly include: General Motors (Chevrolet, Buick, Cadillac, Pontiac, Corvette, etc.), Ford (Lincoln, Mercury, Mustang, etc.), and Chrysler (Dodge, JEEP brands). Domestic brands mainly include: BYD, Chery (Riich, Rely), Geely, Hafei, Great Wall, Hongqi, Zhonghua, Lifan, JAC, FAW, Besturn, Fengshen, Leopaard, Hawtai, Changan, Fenghua, Roewe, MG, Haima, Maple, etc.

Where is the ABS sensor located on the tire?

ABS sensors are located on the inner side of the car tires and can be seen when the car is lifted. There are three types of ABS sensors: linear wheel speed sensors, ring-type wheel speed sensors, and Hall-effect wheel speed sensors. How ABS works: During braking, the ABS system quickly determines the wheel lock-up state based on speed signals from each wheel speed sensor. It closes the normally open input solenoid valve on the wheel that is starting to lock, maintaining constant braking force. If the wheel continues to lock, the normally closed output solenoid valve opens, rapidly reducing braking pressure on that wheel by allowing brake fluid to flow directly back to the reservoir, preventing complete wheel lock-up due to excessive braking force. This keeps the braking condition at the optimal point (20% slip ratio S), achieving the best braking performance and maximum driving safety. Functions of ABS: Maximize brake efficiency, reducing braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. Allow steering during emergency braking, providing good steering control. Avoid violent friction between tires and the ground, reducing tire wear.

What does the maximum speed of a car mean?

Car maximum speed refers to the highest driving speed that a car can achieve on a well-leveled road surface (concrete or asphalt), which is the speed when the driving resistance and driving force are balanced under windless conditions on a flat road surface. The maximum speed is measured in the last 500 meters of a 1.6-kilometer-long test section, with four round trips conducted to obtain the average value. A car is defined as a non-track vehicle powered by an engine, equipped with four or more wheels, primarily used for transporting people and/or goods, towing vehicles that carry people and/or goods, and for special purposes.
