What Causes the Failure of the Auto Hold Function in the Tiguan?

Auto hold function failure is a system malfunction, which also refers to a brake function failure where the vehicle cannot brake automatically. The auto hold function is designed to prevent unnecessary vehicle sliding without the need for the driver to apply the brake for a long time or to activate the electronic parking brake. Solutions for auto hold system malfunction: Turn on the car key, press the foot brake, then hold down the electronic handbrake for 5 seconds, followed by pulling up the electronic handbrake for 5 seconds. This will reset the electronic parking brake. How auto hold works: The auto hold function provides precise parking force through a slope sensor controlled by the system. When starting, the parking control unit calculates information from the clutch distance sensor, clutch engagement speed sensor, accelerator pedal sensor, etc. The parking brake is automatically released when the driving force exceeds the running resistance, allowing the car to start smoothly. How to use auto hold: When the driver has fastened the seat belt and the driver's side door is closed with the engine running, press the auto hold switch to change the function from off to standby. When the brake pedal is pressed to a certain depth and the vehicle has completely stopped, the auto hold function changes from standby to parking status. When auto hold is in parking status, after engaging the appropriate forward or reverse gear and pressing the accelerator pedal, auto hold will automatically release based on the slope's gradient.

Does Using Air Conditioning in the Car Consume More Fuel?

Using air conditioning accounts for about 20% of the engine's power. Indeed, running the air conditioning in a car consumes more fuel. When the air conditioning cooling system is activated, the electromagnetic clutch engages, the compressor operates, and the engine also needs to burn more fuel to provide sufficient energy to drive this load. Here are the reasons why using air conditioning in the car increases fuel consumption: 1. Prolonged use of air conditioning: It's okay to use the air conditioning, but avoid running it for extended periods continuously. Prolonged use can easily wear out the engine, thereby increasing fuel consumption. Moreover, in the relatively small and enclosed space of a car, prolonged use of air conditioning is not conducive to breathing fresh air and can be harmful to health. 2. Blocked air vents: Car owners should ensure that the air vents are not obstructed by debris, allowing the airflow to remain unimpeded. If the vents are blocked, the intensity of the cool air will be affected, prompting the owner to lower the temperature setting further. This not only increases fuel consumption but may also shorten the lifespan of the air conditioning system. 3. Turning on the air conditioning immediately after starting the vehicle: When starting the car, owners should not turn on the air conditioning right away. Since the engine has not fully warmed up at this point, immediately using the air conditioning adds extra load to the engine. Therefore, it's better to wait until the car has fully started and been driven for a while before turning on the air conditioning. This way, the engine's load is not increased, and fuel consumption is minimized.

What to Do When the Car Door Is Locked with Keys Inside?

Here are the solutions when the car door is locked with keys inside: 1. Use the spare key to unlock the door: Vehicles usually come with at least two original keys, one as the primary key and the other commonly known as the spare key. When the primary key is locked inside the car, try to retrieve the spare key. 2. Contact a locksmith: Seek help from a professional locksmith. Documents required when contacting a locksmith: Valid identification: ID card, passport, or household registration booklet; Proof of vehicle ownership: vehicle registration certificate. If the registration certificate is also locked inside the car, you can prove it to the locksmith after unlocking. If you don't have the registration certificate, you need to file a report at the nearest police station. 3. Break the window: If retrieving the key or contacting a locksmith is not feasible, breaking the window is the only option.

How long can a run-flat tire run after a blowout?

After a blowout, you can continue driving for 50-80 kilometers at a speed below 80 km/h without air pressure. The following measures should be taken after a run-flat tire blowout: Do not brake suddenly; instead, slow down gradually. While slowing down, keep both hands firmly on the steering wheel. Turn in the opposite direction of the blowout to ensure the vehicle continues in a straight line. Methods to prevent tire blowouts: Choose radial tires; use low-pressure tires whenever possible; pay attention to whether the speed matches the tire's load capacity during normal driving; maintain standard tire pressure, and avoid pouring cold water to reduce pressure when the tire pressure increases due to high temperatures.

What is the PEPS module?

PEPS stands for Passive Entry and Passive Start system. Below are the main components involved in PEPS and their working process: 1. Door handle switch: Most models use a button-style keyless switch on the door handle, while a few employ capacitive touch. From a user experience perspective, capacitive touch is undoubtedly more elegant and effortless, but the component cost is also higher. Additionally, since capacitive switches are triggered by microcurrents without any pressing motion, owners may occasionally find that when the door handle is wet, the car body has static electricity, and the key is nearby, the doors may unlock/lock. 2. Low-frequency antennas: Typically, PEPS-equipped vehicles are equipped with 4 antennas arranged along the central axis of the car, located at the dashboard, center console, rear seats, and trunk. Due to the short transmission distance of low-frequency signals, multiple antennas are deployed to cover all four doors plus the trunk/tailgate, ensuring keyless operation regardless of which door the owner opens. 3. Car key: The car key can generally receive low-frequency trigger signals while transmitting high-frequency unlock signals. 4. RFR high-frequency receiver: Receives the high-frequency unlock signals sent by the key and transmits the information to the door lock module.

What Cars Are Suitable for Beginners to Practice Driving?

Cars suitable for beginners to practice driving include the Honda Fit, Changan Yidong, Volkswagen Polo, Hyundai Verna, Baojun 310, Geely Vision X1, Toyota Yaris, and Chevrolet Cavalier. When choosing a practice car, small-sized vehicles can be prioritized as they are easier to handle in various complex road conditions due to their compact size. Criteria for Beginner Practice Cars: For a practice car, it's advisable to opt for cheaper models or cost-effective used cars. Not only are they more affordable, but minor scratches won't be too distressing. When selecting a used car, avoid those that are too old, as older vehicles tend to have more issues, leading to unnecessary expenses. It's recommended to choose a used car that is less than 5 years old and known for its stable and durable quality. Reasons for Choosing Small Cars to Practice Driving: When selecting a practice car, small cars are easier to handle compared to larger ones, and low-end cars are simpler to control than high-end models. Beginner drivers often find operations like turning, making U-turns, and reversing challenging, so large, hard-to-control models should be avoided. Choosing a relatively fuel-efficient car, or hybrid and new energy models, can also be good for practice, as they won't incur high fuel costs.
