What Causes Body Vibration During High-Speed Driving?

High-speed body vibration causes: 1. Front wheel alignment angle deviation, excessive toe-in; 2. Low front tire pressure or tire imbalance due to repairs; 3. Front wheel rim deformation or incorrect number of tire bolts; 4. Loose installation of transmission components, bent drive shaft, power imbalance, front axle deformation; 5. Shock absorber failure, inconsistent stiffness of front leaf springs. When vibration occurs at higher speeds and causes steering wheel shake, you can first lift the drive axle, secure the front wheels with safety blocks, start the engine and gradually shift into higher gears to reach the final test vibration speed. If both the body and steering wheel vibrate at this point, it indicates transmission system-induced vibration.

What is the general tire pressure setting?

According to the international GBT2978-2008 standard, the recommended tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: Should not exceed 3.5bar. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches tire cords, reducing elasticity and increasing vehicle load during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate, causing internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Makes the steering wheel heavy and prone to deviation, compromising driving safety; Increases movement of tire parts, causing abnormal heat due to excessive rolling; Weakens cord and rubber functions, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area; Multiplies friction with the ground, rapidly increasing tire temperature and softening the tire, drastically reducing strength. High-speed driving may cause blowouts; Increases tire deformation, causing sidewall cracks and flexing movements, leading to overheating, rubber aging, cord fatigue, and accelerated shoulder wear.

How to Use Turn Signals When Entering a Roundabout?

Roundabouts are typically set up at intersections with multiple roads (three or more). Below are the three methods for using turn signals at roundabout intersections: 1. Turning left when entering the roundabout: Since the vehicle needs to move from the outer lane to the inner lane, the driver should activate the left turn signal when entering the roundabout. Before exiting the roundabout, the driver should switch to the right turn signal in advance, ensure safety, and then change lanes from the inner lane to exit the roundabout. 2. Going straight when entering the roundabout: Since the vehicle does not need to change lanes after entering the roundabout, the driver does not need to activate the left turn signal when entering. When preparing to exit the roundabout to continue straight, the driver should activate the right turn signal to alert other vehicles, as they will need to cross the right lane inside the roundabout before exiting. 3. Turning right when entering the roundabout: The situation when entering the roundabout is similar to going straight, so the left turn signal is also unnecessary. After selecting the appropriate exit, the driver should activate the right turn signal in advance, ensure safety, and then turn right to exit the roundabout.

Do You Need to Press the Brake When Shifting Gears in a Manual Transmission?

Shifting gears in a manual transmission does not require pressing the brake. Detailed information about manual transmission shifting is as follows: 1. When shifting gears, the clutch and throttle must be coordinated properly. Press the clutch all the way down, then immediately release the throttle pedal, and quickly shift to the corresponding gear. After shifting, release your hand immediately and avoid keeping it on the gear lever for too long, as this can easily damage the lever. 2. It is also important to use the correct hand position when shifting gears. Many drivers often neglect the proper hand position, sometimes casually using two or three fingers to shift, which is neither standard nor safe. The correct hand position is to cover the gear lever head with your palm facing downward and then shift gears.

How Does a Tire Pressure Monitoring System Work?

Automotive tire pressure monitoring systems operate on the following principles: 1. Direct TPMS: Utilizes pressure sensors installed in each tire to directly measure tire pressure, then transmits the pressure data wirelessly from inside the tire to a central receiver module for display of individual tire pressure readings. 2. Indirect TPMS: When a tire's pressure decreases, the vehicle's weight causes that wheel's rolling radius to reduce, making it rotate faster than other wheels. By comparing rotational speed differences between tires, the system monitors pressure indirectly. Indirect TPMS essentially relies on calculating tire rolling radius to monitor pressure.

How to Remove the Rear Headrest of a Passat?

To remove the rear headrest of a Passat, follow these steps: 1. Lift the headrest upwards until it can't go any further, which should be the second notch position. 2. On the right side of the connection between the headrest and the seat, there is a button at the back. Press the button outward while pulling the headrest upwards to remove it. Here is some information about the Passat: 1. The Passat (PASSAT) is a mid-size sedan designed by Volkswagen AG in Germany. 2. Since its debut in 1973, the Passat has been a global success in the automotive market for over 40 years, known for its high safety standards, classic design, and top-tier manufacturing quality, with over 20 million units produced and sold worldwide.
