Why doesn't a tire pressure of 1.9 trigger an alarm?

A tire pressure of 1.9 not triggering an alarm is because the minimum tire pressure alarm threshold varies for each vehicle model. This is mainly related to the settings of each vehicle's onboard computer. Generally, the low-pressure alarm threshold for most vehicles is set at 1.9. Hazards of excessively low or high tire pressure: Both underinflation and overinflation can shorten tire lifespan. Underinflation increases tire deformation, making the sidewalls prone to cracking. It also causes excessive flexing, leading to overheating, accelerated rubber aging, and even blowouts. It enlarges the tire's contact area with the road, accelerating shoulder wear. Overinflation causes excessive tire expansion and reduced elasticity, increasing the risk of blowouts upon significant impact. It also leads to rapid tread wear. Functions of tire pressure monitoring alarms: Prevent blowouts by monitoring tire pressure and temperature in real time, addressing issues before they occur. Save fuel by maintaining correct tire pressure, reducing vehicle fuel consumption. Reduce wear – insufficient pressure causes excessive wear (tire scrubbing) and shortens tire lifespan.

Is Tire Pressure Higher in Winter or Summer?

Winter tire pressure should be slightly higher than in summer due to thermal expansion and contraction. Since the weather is colder in winter, the tire pressure can be adjusted upward by 0.1 based on the normal value. Below are the methods for checking tire pressure and the hazards of both overinflation and underinflation: Methods for Checking Tire Pressure: The most standard tire pressure value can be found on the tire pressure label located on the driver's side front door frame, which indicates the original tires and their corresponding tire pressures. The tire pressure data refers to the cold tire pressure, which applies to both summer and winter tires. Hazards of Overinflation or Underinflation: Both underinflation and overinflation can shorten the lifespan of tires. Underinflation increases tire deformation, making the sidewalls prone to cracks. It also causes excessive flexing, leading to overheating, accelerated rubber aging, and even blowouts. It increases the tire's contact area, accelerating wear on the tire shoulders. Overinflation, on the other hand, causes excessive tire expansion, reducing elasticity. If subjected to significant impact, the tire may burst. Additionally, overinflation accelerates wear on the tire tread.

Has the Biannual Inspection Policy for Vehicles Over 15 Years Old Been Canceled?

The policy requiring biannual inspections for vehicles that have reached 15 years of age has not been canceled and remains in effect under the original vehicle inspection regulations. Inspection Schedule: The annual vehicle inspection schedule is determined by the initial registration date of the vehicle. For example, if the registration date on the vehicle's license is June 2015, then the annual inspection should be conducted every June. Additionally, according to Article 40 of the newly revised "Motor Vehicle Registration Regulations," vehicle owners can apply for an inspection compliance mark at the local vehicle management office up to three months before the expiration of the current inspection period. This means that vehicles due for inspection in June can undergo the inspection in April, May, or June. Vehicle Inspection Items: Inspection includes an exterior check, emissions testing, window tint transparency check, violation check, and a comprehensive safety inspection covering the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, license plate installation, and more.

How to Replace the Battery of a Levin Car Key?

The steps to replace the battery of a Levin car key are as follows: 1. Unlock and remove the mechanical key. 2. Remove the key cover, wrapping the head of a flathead screwdriver with a cloth to prevent damage to the key. 3. Use a small flathead screwdriver to remove the depleted battery. 4. Ensure the new battery is placed with the positive side facing up. 5. When reinstalling the key cover and mechanical key, follow steps 2 and 1 in reverse order. 6. Test the key functions to ensure they are working properly. Notes for battery replacement: (1) Improper battery replacement may damage the car key. (2) Using an unsuitable or non-compliant battery may damage the car key. Pay attention to the voltage, size, and specifications when purchasing a new battery. (3) Following the steps correctly usually ensures a smooth replacement. If issues arise during the process that cannot be resolved, it is recommended to call the 4S store for assistance. (4) Avoid using the key beyond its effective range, as excessive use outside this range may cause the key to malfunction. (5) Being within a 1-meter range of a magnetic field may cause the battery to become magnetized and fail. (6) Ensure hands are dry during the disassembly process, as moisture can cause the battery to rust.

Can a Car Battery That Doesn't Hold Charge Be Repaired?

Car batteries that don't hold charge can be repaired. Here are the details: 1. If the issue is insufficient electrolyte, you can add distilled water or purified water to the battery. However, tap water should not be used as it can cause severe self-discharge of the battery. 2. If the battery voltage is insufficient, below 11V, you can use a repair device's high-resistance repair function to raise the voltage above 11V, which is necessary for charging. If the battery voltage is below 10V and cannot be improved through charging or repair, the battery must be replaced. 3. If the electrodes are sulfated, this condition cannot be repaired, and the battery needs to be replaced. If the battery is aging, it is also recommended that the owner replace it as soon as possible. 4. The battery is a crucial component of the car, and regular maintenance should be observed. 5. Long-term parking can cause the battery to lose charge or become damaged. If the car needs to be parked for an extended period, the battery's electrode cables should be disconnected to avoid complete discharge. Try not to leave the car unused for more than 10 days. For long-term parking, the car should be started approximately every 5 days, keeping the engine idling to allow the alternator to charge the battery.

Where is the deflector located on a vehicle?

The deflector is a downward-sloping connecting panel installed below the front bumper of a car. Definition of automotive deflector: To reduce the lift generated when a car is driving at high speeds, automotive designers have made improvements to the car's exterior shape by tilting the entire body forward and downward to create downward pressure on the front wheels, flattening the rear to minimize the negative air pressure acting from the roof to the rear and preventing the rear wheels from lifting. Additionally, a downward-sloping connecting panel is installed below the front bumper. This panel is integrated with the front skirt of the car body and features appropriately placed air inlets to increase airflow and reduce air pressure beneath the car. This connecting panel is referred to as a deflector. Necessity of deflectors: In aerodynamics, a theory proven by French physicist Bernoulli states that the speed of airflow is inversely proportional to pressure. In other words, the faster the airflow, the lower the pressure; the slower the airflow, the higher the pressure.
