What Causes Heavy Electric Power Steering?

Electric power steering feels heavy due to: 1. Insufficient tire pressure; 2. Installation of different tire models; 3. Damaged or poorly sealed dust boots; 4. Contaminated, insufficient, or aerated power steering fluid; 5. Uncalibrated torque sensor; 6. Deformed front suspension or abnormal wheel alignment; 7. Sticking steering column. The steering wheel connects to the steering shaft via splines, converting driver-applied force at the wheel rim into torque transmitted to the shaft. To lighten electric power steering: 1. Start the engine, engage gear, wait 3 seconds; 2. Turn wheels fully left/right for 3 seconds, then return to center and shut off engine.

What is the maximum distance allowed for driving in second gear during Subject 3 test?

Generally, the speed in second gear during Subject 3 test should not exceed 20 km/h, but there is no minimum speed limit. This means it's acceptable to neither press the clutch nor accelerator after shifting to second gear. However, it's important to note that there are distance restrictions for first and second gears during the Subject 3 examination. When shifting from second to third gear, the gear change should occur at approximately 21-22 km/h. Additional information: For C1 license Subject 3 test, vehicles typically start in first gear and can shift to second gear once moving, as there are specific distance limitations for first and second gear usage during the exam - exceeding these limits will result in test failure. When driving in second gear, shift to third gear when reaching 20 km/h, and shift to fourth gear when exceeding 30 km/h.

Can You Still Drive When the Audi TPMS Light Comes On?

Audi TPMS light on indicates that the tire pressure of a certain tire may be too low or the sensor battery is insufficient. If the light comes on while driving, please stay calm, do not panic, immediately reduce the speed and avoid fast steering and sudden braking, then check the tire pressure. The following are the functions of the tire pressure monitoring system: 1. Prevent accidents: The tire pressure monitoring system is a type of active safety equipment. It can issue an alarm in time when there are dangerous signs in the tires, reminding the driver to take corresponding measures, thereby avoiding serious accidents. 2. Extend the service life of tires: With the tire pressure monitoring system, we can keep the tires working within the specified pressure and temperature range at any time, thereby reducing tire damage and extending the service life of tires. Data shows that when driving with insufficient tire pressure, when the tire pressure is 10% lower than the normal value, the tire life will be reduced by 15%. 3. Make driving more economical: When the tire pressure is too low, the contact area between the tire and the ground will increase, thereby increasing friction resistance. When the tire pressure is 30% lower than the standard value, fuel consumption will increase by 10%. 4. Reduce the wear of the suspension system: When the tire pressure is excessive, the shock absorption effect of the tire itself will be reduced, thereby increasing the burden on the vehicle's shock absorption system. Long-term use will cause great damage to the engine chassis and suspension system; if the tire pressure is uneven, it is easy to cause the brakes to deviate, thereby increasing the wear of the suspension system.

What Causes the Jerking of CVT at Low Speeds?

CVT jerking at low speeds is caused by engine carbon buildup or spark plug failure. Here are the relevant explanations: 1. Engine carbon buildup: When carbon builds up in the vehicle's engine, it not only leads to reduced power and increased fuel consumption but also causes unstable idling, resulting in jerking during cold starts. Additionally, if the spark plugs' ignition efficiency declines, the combustion conditions in each cylinder will vary significantly, leading to engine vibration accompanied by noticeable jerking. 2. Spark plugs: This issue may also be caused by insufficient engine warm-up. When the engine is cold, the oil's fluidity is poor, preventing effective lubrication of the engine pistons, which results in severe jerking during operation. Once the engine temperature returns to normal, this phenomenon will disappear. If the engine continues to jerk when warm, it is necessary to promptly visit a repair shop for inspection and maintenance.

Can You Step on the Accelerator When Passing Through a Traffic Light in Subject Three?

In the driving test Subject Three, stepping on the accelerator is necessary because the test includes operations such as the 100-meter gear shifting, which requires the examinee to proficiently control gear shifting and accelerate. Notes: 1. When shifting from first gear to second gear and from second gear to third gear, the clutch release should be slow, and the acceleration should also be gradual. 2. When shifting to fourth gear or fifth gear, the clutch release should be quick, and the accelerator should be pressed swiftly. 3. At turns and intersections, try to continue driving at first gear speed without stopping if possible. 4. Both 180° turns and parking starts require first gear. 5. When driving straight, the steering wheel rotation should not exceed 5°; make minor adjustments as needed. 6. At zebra crossings, check traffic on both sides. 7. When changing lanes, observe the traffic situation behind the lane.

Is it allowed to drive over dashed lines when turning in Subject 3?

It is allowed to drive over dashed lines when turning in Subject 3, but not solid lines. Additional information: Deduction items for turning in Subject 3 exam: 1. Left turn at an intersection: (1) Failing to slow down or stop and observe as required, deduct 100 points. (2) Failing to observe the left and right traffic conditions, and not observing the front traffic conditions when turning through the intersection, deduct 100 points. (3) Entering the intersection when there is traffic congestion and stopping the vehicle inside the intersection to wait, deduct 100 points. 2. Right turn at an intersection: (1) Failing to slow down or stop and observe as required, deduct 100 points. (2) Failing to observe the left and right traffic conditions, and not observing the front traffic conditions when turning through the intersection, deduct 100 points. (3) Entering the intersection when there is traffic congestion and stopping the vehicle inside the intersection to wait, deduct 100 points.

Which lights should be turned on when the headlights are activated in Subject 3?

Activating the headlights refers to turning on the low beam to provide illumination for the driver. Below is a detailed introduction to the Subject 3 exam: 1. Overview: Subject 3, which includes the road driving skills test and the safety and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's exam. The content of the road driving skills test varies depending on the type of vehicle being licensed. 2. Exam Content: The road driving skills test for Subject 3 generally includes: preparation before getting in the car, simulated lighting test, starting, driving in a straight line, shifting gears, changing lanes, pulling over, driving straight through intersections, turning left at intersections, turning right at intersections, crossing pedestrian crossings, passing school zones, passing bus stops, and meeting other vehicles.
