It indicates an issue with the steering system. Below is a detailed analysis of why the yellow light is on: 1. Steering: If a yellow light appears on the dashboard steering wheel symbol in a Tiguan, it means there is a problem with the vehicle's steering system, prompting the owner to drive to a service station for repairs. If a red light appears, the power steering system is compromised. If the steering wheel loses power assistance, it will become very heavy to turn. 2. Precautions: (1) Check the lubrication of mechanical connections in the steering system. (2) Open the power steering reservoir to inspect fluid level and whether the steering fluid/filter element is clean. (3) Examine steering rods and pressure bearings for damage or deformation. (4) Start the engine and wiggle the steering wheel left-right to check for excessive play/looseness in mechanical connections. (5) Lift the steering axle and shake the wheels vertically to check for play in the steering knuckle assembly. (6) Start the engine to inspect the entire hydraulic steering system for oil leaks.

As an experienced driver, I've encountered the yellow steering wheel warning light on the dashboard several times. This usually indicates a fault in the electric power steering system, with possible causes including sensor failure, poor wiring contact, or the need for control module software updates. While driving, you can clearly feel the steering wheel becoming heavier, making turns particularly strenuous. First, I try restarting the vehicle to see if the light goes off; if it remains lit, I check whether the battery voltage is stable, as low voltage often triggers false alarms. Ultimately, it's necessary to visit a professional repair shop to read the fault codes with diagnostic equipment for an accurate diagnosis. Ignoring it may lead to power steering failure, affecting safe driving. Therefore, I recommend paying extra attention to this system during routine maintenance, with prevention as the priority.

How to Correctly Step on the Accelerator and Clutch in Subject Three?

Subject Three: The correct method of stepping on the accelerator and clutch is introduced as follows: 1. Seat adjustment: Adjust the seat. Many people forget to adjust the seat before the test, resulting in discomfort all over the body, or even inability to see the reference points clearly. To control the clutch and accelerator, place your right foot on the accelerator pedal, ensuring it feels comfortable—neither too far to reach nor too crowded. Both hands should rest comfortably on the top of the steering wheel. 2. Foot posture: Place the heel of your right foot on the floor of the driver's compartment as a pivot point, with the ball of your foot resting on the pedal. Use the strength of your ankle joint to move back and forth, ensuring it feels comfortable—discomfort is not acceptable. 3. Starting: First, press the clutch all the way down, shift into first gear, and then slowly release the clutch until the car noticeably vibrates. Releasing it too quickly will cause the engine to stall. At this point, gently press the accelerator with your right foot in sync with the vehicle's speed—press it slowly, as pressing too hard will cause the car to jerk forward. Once the clutch is fully released, the car will start smoothly. 4. Shifting gears: Upshifting: Before upshifting, ensure coordination between the accelerator and clutch. First, release the clutch, then press the accelerator, allowing the speed to increase gradually—avoid pressing the accelerator abruptly. Downshifting: If the speed is too high, lightly press the brake before downshifting.

Should You Use a Low or High Gear on Bumpy Roads?

When driving on bumpy roads, the correct approach is to shift to a lower gear and gradually release the accelerator pedal. Gradually releasing the accelerator pedal allows the vehicle to pass through the bumpy section smoothly at a low speed, enabling the car to move forward at idle. Shifting to a lower gear provides more engine traction. More details are as follows: 1. Reason for choosing a lower gear: Selecting a lower gear is because when driving on uneven roads, using a low gear at idle or with slight acceleration can reduce the impact from the rough surface and alleviate body vibrations. 2. Reason for gradually releasing the accelerator: Gradually releasing the accelerator is necessary because when the vehicle is moving slowly, a sudden release of the accelerator can cause jerking, which affects the vehicle's transmission components. Therefore, in normal operation, slowly releasing the accelerator pedal helps avoid jerking.

How to Determine if a Torque Converter is Faulty?

Torque converter faults can be identified through the following symptoms: 1. Torque converter overheating: Overheating causes a decrease in transmission oil viscosity and damage to rubber oil seals, resulting in loss of lubrication and oil leakage. It also leads to insufficient power in loaders and deterioration of torque converter performance, which is one of the most common fault phenomena. Common causes include: insufficient oil supply from the hydraulic pump, faults in the cooling system, incorrect or degraded oil type, oil pressure in the torque converter being lower than the adjustment pressure of the main pressure valve, and excessively low outlet pressure of the torque converter. Another reason could be poor structural design of the torque converter, leading to abnormal wear. 2. Insufficient output of the hydraulic torque converter and driving force of the loader: When the loader operates at low speed, the diesel engine's power is transmitted from the pump wheel to the turbine, while the guide wheel remains stationary. The reaction torque generated by the guide wheel combines with the torque from each pump wheel and is transmitted to the turbine, providing speed reduction and torque increase, ensuring driving force under low-speed and heavy-load conditions. If the overrunning clutch is damaged, the engine's torque can only be transmitted through a single guide wheel or directly to the turbine, reducing torque conversion efficiency and causing insufficient power. This may even eliminate the speed reduction and torque increase effect, and stepping on the accelerator in this condition could cause the engine to stall.

What are the penalties for a 5-seater private car carrying 6 people?

For a 5-seater private car carrying 6 people, the penalty is 3 demerit points and a fine of 100 RMB. Below are relevant details about driving private cars: 1. Explanation: For driving non-commercial vehicles, exceeding the approved number of passengers by less than 20% results in 3 demerit points and a fine of 100 RMB; exceeding by 20% or more results in 6 demerit points and a fine of 200 RMB. 2. Hazards of overloading: (1) Vehicle overloading severely damages road infrastructure. Since overloaded vehicles far exceed the design load of roads and bridges, it leads to pavement damage, bridge fractures, and significantly shortens their service life. (2) Overloaded vehicles have increased mass and inertia, leading to longer braking distances and higher risks. Severe overloading can cause tire blowouts, sudden swerving, brake failure, rollovers, and other accidents due to excessive tire load and deformation. Additionally, overloading affects the vehicle's steering performance, increasing the likelihood of accidents due to loss of steering control.

Is it necessary to obtain the vehicle certificate of conformity on the day of picking up the car?

When picking up the car, the 4S store should hand over the certificate of conformity to the car owner. The following is the importance of the vehicle certificate of conformity: 1. Essential document for vehicle registration: The vehicle certificate of conformity is very important as it serves as a credential for the car and is also a necessary document for vehicle registration. In addition, the car purchase invoice, the three-guarantee service card, and the vehicle instruction manual are all important credentials for a new car. If the owner finds any of these documents missing before payment, they should promptly request them from the dealer. 2. Failure to provide the certificate of conformity constitutes a serious breach of contract: The vehicle certificate of conformity must be provided by the 4S store before the car owner makes the payment. From a legal perspective, regardless of any reason, the car certificate of conformity cannot be withheld. If the car dealer delays or refuses to deliver the product certificate of conformity, this behavior constitutes a serious breach of contract, and the owner can request the dealer to terminate the sales contract and compensate for the corresponding losses.

What are the methods to distinguish genuine from fake used catalytic converters?

Methods to distinguish genuine from fake used catalytic converters are as follows: 1. Pore arrangement: In a normal catalytic converter, the pores of the internal porous ceramic should be uniformly arranged and consistent in size, with the porous ceramic being clean and relatively white (a yellowish beige color indicates a fake). 2. Assembly: The porous ceramic inside the catalytic converter, serving as a carrier, should be firmly and securely assembled with the outer shell, with no signs of looseness (even slight looseness is unacceptable). 3. Dimensions: The replacement catalytic converter should match the original factory dimensions in terms of size, the material of the internal porous ceramic, the arrangement pattern of the pores, and the number of rows. 4. Steel stamp: The encapsulation of the catalytic converter must be performed by an enterprise with nationally recognized environmental qualifications, and the manufacturer's steel stamp must be printed on it.
