Characteristics of the coolant temperature sensor: The engine ECU receives the signal from the coolant temperature sensor as a correction signal for fuel injection and ignition. By utilizing the coolant temperature sensor, drivers can promptly identify and address issues. Below is an introduction to the temperature sensor: 1. The coolant temperature sensor is installed in the engine block water jacket or coolant pipeline, in contact with the coolant, to detect the engine's coolant temperature. After receiving this temperature signal, the ECU adjusts the fuel injection timing and ignition timing. 2. The slender head of the engine coolant temperature sensor is in contact with the coolant, containing a negative temperature coefficient thermistor inside. Upon receiving the signal from the coolant temperature sensor, the ECU adjusts the fuel injection timing and ignition timing of the engine.

Where is the Touran's cabin air filter located?

The Touran's cabin air filter is located behind the glove box. To remove the Volkswagen Touran's cabin air filter, first open the glove box cover. Locate the fixing clip on the right side of the glove box and pull it outward with force. Remove the fixing clip of the glove box cover to detach it. Squeeze both sides of the glove box towards the center with both hands, then remove the glove box to reveal the cabin air filter cover. Additional information: 1. The manufacturer recommends replacing the cabin air filter every 10,000 kilometers or once a year, with cleaning possible every 5,000 kilometers. 2. However, if the air conditioning is frequently used in severely polluted environments or areas with heavy dust and mud, the replacement interval should be shortened accordingly. 3. The steps and operations for replacing the cabin air filter are relatively complex, so it is generally recommended to seek professional assistance at a 4S store or automotive after-sales service center for removal and installation.

What Causes a Dead Battery in the Buick Envision?

For a dead battery in the Buick Envision, it is recommended that the owner wait for assistance from a 4S dealership. Below are the reasons why the Buick Envision can only wait for professional help when the battery dies: 1. Because the Envision's battery is not a standard battery but a specialized AGM battery for start-stop systems, the charging method differs and cannot be charged by oneself. 2. Due to the frequent engine restarts required by the start-stop system, the battery must support frequent high-current discharges. Correspondingly, when the vehicle's charging system recharges the battery, the battery must also have strong charge acceptance performance and high capacity to meet the electrical demands of onboard electronics when the engine is off. Occasionally jump-starting the vehicle once is generally not a major issue. As long as the starting voltage is appropriate and the output current is sufficient, jump-starting is possible. However, there are specific operational standards and techniques involved; improper handling can easily damage the vehicle's computer.

How to Reset the Sunshade of Tiguan's Sunroof?

The owner should first turn on the car's power to ensure the sunroof motor can function. Then locate the sunroof control button on the ceiling near the upper right side of the driver's seat. The owner should press the backward button once, followed by the forward button. After the sunroof is fully closed, rotate the round knob clockwise to the end. Below are the reset method and precautions for the sunroof: 1. Before opening the sunroof, check for any obstacles on the roof that might hinder its sliding. Avoid using the sunroof on bumpy roads to prevent damage to the sunroof and related sliding rail components due to vibrations. Do not open the sunroof during rainy days or when washing the car to prevent rainwater or water droplets from accelerating the aging and rusting of the rubber seals and metal parts. 2. After the sunroof is fully closed, rotate the round knob clockwise to the end. The sunroof control button consists of three parts: the round knob is for left and right rotation to adjust the sunroof size, the forward arrow is the closing button, and the backward arrow is the opening button.

How to Reset the Rear Tilt Function of the Tiguan Sunroof?

To reset, the sunroof must be fully closed, which can be achieved using the manual crank. Below are the steps to reset the rear tilt function of the Tiguan sunroof: 1. First, adjust the dust-proof net spring of the sunroof and lubricate the sunroof sliding rails. The sunroof must be fully closed for resetting, and the manual crank can be used to close it. 2. Turn on the ignition, press and hold the round sunroof switch downward for a few seconds until the sunroof automatically opens and then closes, then release the switch. If the sunroof occasionally opens automatically, replace the sunroof switch. 3. If the rear tilt of the Tiguan sunroof cannot be closed, it may be due to debris in the sunroof rails or a malfunction of the sunroof motor. If there is debris in the rails or insufficient lubrication, excessive resistance may prevent closure, so lubrication may help. When the rear tilt cannot be closed, first check the rails, as lack of lubrication is a common cause. Excessive resistance may trigger the automatic anti-pinch function, resulting in the sunroof not closing.

What tires does the Sylphy car use?

Sylphy is equipped with Dunlop SPORT270 tires, size 195/60R16. Below is relevant information about the tires: 1. Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. They are usually installed on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance. 2. Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning performance. 3. Additionally, they are required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, highlighting the significant rubber demand for tires. 4. Tire performance declines over time and with usage. When replacing tires, use tires with the same size, speed rating, and load capacity as the original tires.
