The normal tire pressure range for a Mercedes GLC260 is 2.4bar to 2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data is based on the international GBT2978-2008 standard requirements. The GLC260's tire pressure monitoring is passive and does not display specific values. It only alerts on the dashboard when the tire pressure is abnormal. Generally, a tire pressure exceeding 2.8bar is considered too high, while a pressure below 2.0bar is too low. Hazards of overinflated tires: Reduced friction and adhesion, affecting braking performance; causes steering wheel vibration and misalignment, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting other components' longevity; overstretches tire cords, reducing elasticity and increasing load during driving. Hazards of underinflated tires: Increased friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to misalignment, compromising safety; increases movement in tire parts, causing abnormal heat from excessive rolling; weakens cord and rubber functionality, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a blowout. If the tire pressure monitoring indicator lights up (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), it is generally due to one of three reasons: Abnormal tire pressure: Typically alerts when below 1.8bar or above 3.0bar. Immediate tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, failing to reset the tire pressure monitoring system, which still records the previous data, causing the indicator to light up. Simply reset the tire pressure. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If damaged during driving (e.g., by impact), it triggers the warning light. A damaged sensor must be replaced.

Can vehicle inspections be conducted on October 1st National Day?

In general, most locations do not conduct vehicle annual inspections during the National Day holiday. Vehicle inspection time standards: Operational passenger vehicles must be inspected once a year within 5 years; after exceeding 5 years, every 6 months. Trucks and large/medium-sized non-operational passenger vehicles must be inspected once a year within 10 years; after exceeding 10 years, every 6 months. Small and mini non-operational passenger vehicles must be inspected once every 2 years within 6 years; after exceeding 6 years, once a year; after exceeding 15 years, every 6 months. Inspection exemption policy: 6-seat and smaller family vehicles enjoy a 6-year inspection exemption policy. The prerequisite for the 6-year exemption is no major traffic accidents during this period. If an accident occurs, an on-site inspection is mandatory. 7-seat and larger vehicles do not qualify for the 6-year exemption policy and must still be inspected every 2 years for the first 6 years.

What Causes the Key to Get Stuck After Parking?

Reasons why the key gets stuck after parking are as follows: 1. Key stuck after parking: First, check if the gear is in neutral, then turn the steering wheel slightly. 2. If the key cannot be removed after turning off the engine: It may be that the P gear did not touch the electronic sensor, or there may be debris inside. Check if there is any debris blocking the slot and clean it out. Then, shift the gear again and confirm it is properly positioned, after which the key can be removed. 3. If the key cannot be turned after insertion: It may be due to incorrect positioning during the last parking, causing the steering wheel to lock abnormally. Simply turn the key while gently shaking the steering wheel left and right.

How Many Days in Advance Can Vehicle Owners Renew Their Driver's License?

You can apply for a license renewal at the vehicle management office up to 90 days before your driver's license expires. The consequences of failing to renew an expired driver's license are as follows: 1. If the license has been expired for less than one year: As long as the holder renews it promptly, there will be no issues. 2. If the license has been expired for more than one year but less than three years: The license will be in a "revocable but recoverable" status, and the holder must apply at the vehicle management office to take the Theory Test (Subject One). The license can only be retrieved after passing the exam. 3. If the license has been expired for three years or more: The license will be permanently revoked, and the holder must re-enroll in a driving school and retake all exams to obtain a new license.

Can a Vehicle Have Two Vehicle Licenses?

It is procedurally feasible to obtain an additional vehicle license. At the vehicle management office, one can claim the loss of the original license to acquire a duplicate. However, this practice is illegal and not advisable. Below is more relevant information about vehicle licenses: 1. The vehicle license bears an annual inspection seal (social vehicles require annual inspection, while private vehicles are inspected every two years for the first six years). Upon expiration, one of the licenses will become invalid. 2. This act is illegal. If a stolen vehicle is traced back to having a license, the truth will come to light, and the loss cannot be calculated at just 5%. The consequences are imaginable.

What maintenance items are required for a car at 45,000 kilometers?

For a car at 45,000 kilometers, the routine maintenance includes changing the engine oil and oil filter, replacing the air filter, cabin air filter, and fuel filter—essentially replacing all three filters. Additionally, a comprehensive inspection and cleaning of the entire vehicle should be performed. The most critical aspects of car maintenance are changing the engine oil and oil filter, washing the car, and regularly checking the tire tread and pressure, oil level, coolant level, and brake fluid level. Below are five key points for engine maintenance: Maintenance points: Use the appropriate grade of engine oil and change it regularly (every 5,000 kilometers) along with the filter. Maintain the air cleaner frequently and replace it periodically (every 20,000 kilometers). Clean the fuel system regularly and replace the fuel filter (every 30,000 kilometers). Service the radiator cooling mesh periodically (every 30,000 kilometers). Replace the spark plugs (every 40,000 kilometers or based on driving conditions).

Is it safe to drive with a tire pressure of 172?

When the tire pressure is 172, it is not safe to continue driving because low tire pressure increases tire movement, generates excessive friction leading to temperature rise, softens the tire, and reduces its strength. Prolonged high-speed driving under such conditions may result in a tire blowout. Relevant information about tire pressure is as follows: Normal tire pressure range: The ideal tire pressure ranges between 2.3 to 2.7 BAR. However, during summer when temperatures are high, tire pressure may rise above 3.0 BAR after driving. Therefore, maintaining tire pressure between 2.3 to 2.5 BAR in summer is more appropriate. Consequences of low tire pressure: Increases friction coefficient with the road surface, leading to higher fuel consumption; causes steering wheel heaviness and potential alignment issues, compromising driving safety; excessive tire movement leads to abnormal heat generation; friction with the ground multiplies, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength, which can cause a blowout during high-speed driving; low pressure increases tire deformation, leading to sidewall cracks, flexing movements, excessive heat, rubber degradation, fabric layer fatigue, cord breakage, and increases the tire's contact area, accelerating shoulder wear.
