Here are the reasons for the abnormal noise when releasing the brake during startup: 1. The sound is caused by friction between the brake pads and brake discs. New cars may produce similar noises when braking, as new brake pads and discs require a break-in period. This noise is normal during braking. Both brake discs and pads are high-wear components that experience friction with each brake application, leading to natural wear over time. Excessive wear will eventually cause abnormal noises, so regular inspection and replacement are necessary. 2. Issues with the brake system. This is most likely due to improperly installed or aged rubber seals in the brake caliper, which can cause abnormal noises.

Does Oil Film Remover Damage Glass?

Oil film remover does not damage glass. Below is relevant information about automotive glass: 1. Introduction: Normally, OEM suppliers use zero-inventory matching for complete vehicle glass, meaning the glass manufacturer provides full vehicle matching before the car rolls off the production line. Therefore, the production dates of all glass pieces on a vehicle are generally the same. If they differ, it can be concluded that the glass was removed and reinstalled during assembly, indicating a reworked vehicle. Of course, such rework doesn't necessarily imply quality issues—it might just be minor production adjustments. 2. Vehicle Condition Assessment: (1) Check if the production dates of all glass pieces are identical. If yes, it indicates the vehicle hasn't suffered major collisions. (2) If any piece of glass has a different production year from others, it means that piece was replaced. (3) If the production date of the windshield is very close to the current year when inspecting the car, this vehicle should definitely not be purchased.

Does keeping the auto hold function on all the time harm the car?

Keeping the auto hold function on all the time does not harm the car and can be used with confidence. Here is the relevant introduction to the auto hold function: 1. Introduction: The English name of auto hold is AUTOHOLD, which is a function that automatically applies the handbrake. After activating this function, for example, when stopping at a traffic light, it is equivalent to not having to pull the handbrake. This function is particularly suitable for uphill and downhill driving as well as frequent starting and stopping. 2. Function: The auto hold function, when encountering situations such as traffic lights that require a short stop, the system will automatically brake the wheels after the vehicle comes to a stop to prevent rolling; when starting on an uphill slope, the system will automatically brake to prevent rolling backward, and after starting, the system will automatically release the wheels to move forward directly; when parking and locking the car, there is no need to pull the handbrake, as the system will automatically brake the wheels at this time.

What is the maximum age for driving?

The maximum driving age is generally between 70-80 years old. Here are the specific age regulations for driving motor vehicles: 1. Holding a C1 driver's license: Once the driver reaches 70 years old, the C1 license requires annual review, including a physical examination. The driver must submit a 'Driver's Physical Condition Certificate' within 30 days after the end of the scoring cycle. Failure to submit this certificate will result in license invalidation the following year. If the certificate is submitted and the vehicle management office determines the driver is still physically capable, driving privileges continue. If deemed unfit, the license will be revoked. 2. Holding A1, A2, A3, B1, B2, N, or P licenses: Upon reaching 60 years old, drivers must exchange these licenses for a C1 license (for small passenger cars only) at the original issuing authority. After conversion to C1, annual review and physical condition certification are required starting at age 70.

Where is the cruise control on the Honda Odyssey?

Honda Odyssey's cruise control is located on the right side of the steering wheel. Press the cruise button integrated on the right side of the steering wheel, then set the speed. Note that the system can only be activated when the speed reaches above 40 km/h. The cruise control system, abbreviated as CCS, is also known as the speed control device or autonomous driving system. Its function is to automatically maintain the vehicle speed as required by the driver without pressing the accelerator pedal, allowing the vehicle to travel at a fixed speed. The Odyssey is a vehicle launched by Honda. In terms of body dimensions, its length, width, and height are 4845mm, 1802mm, and 1697mm respectively, with a wheelbase of 2900mm. In terms of appearance, the Odyssey has been redesigned with a more streamlined and refined front grille, showing restrained sharpness. The newly designed rear styling is completely refreshed, featuring a stylish and fashionable LED taillight cluster that perfectly combines form and function.

Does Cruise Control Harm the Car?

Cruise control does not harm the car. Here is a detailed introduction to situations where cruise control should not be used: 1. Mountainous or winding roads: Normally, when exiting a curve, it is necessary to appropriately accelerate to provide greater steering force. In cruise control mode, the vehicle automatically maintains a constant speed, with the throttle controlled by the onboard computer, which can often pose a danger when driving on winding roads. Under such conditions, it is advisable to control the speed appropriately. 2. Roads with dense crowds or heavy traffic: Using cruise control on urban roads with dense crowds and heavy traffic makes it difficult to adjust the speed promptly according to actual road conditions, increasing the risk of traffic accidents. Similarly, if there is heavy traffic on highways or sections marked as accident-prone, it is best to avoid using cruise control. 3. Rainy or snowy weather: Due to slippery road surfaces caused by rain or snow, the car's handling is reduced, and road visibility is poor. Drivers should maintain constant control over the speed, so cruise control should not be used.

What Does Sport Mode Mean?

Sport mode is a driving mode in automatic transmission vehicles. In sport mode, the gear shift RPM is increased, resulting in slower gear shifts and thus faster acceleration for the vehicle. Below is some related information about automatic transmissions: 1. Automatic Principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume over 10% more fuel than manual transmissions. Whether manual or automatic, the more gears there are, the more fuel-efficient the vehicle will be. 2. Driving Tips: For manual transmission vehicles, higher RPMs should be used when shifting gears. Engines are designed to operate at higher RPMs, with various components' dynamic balance and rotational inertia parameters optimized for high-speed conditions. If the engine operates for extended periods outside its normal working range, internal components experience increased load and wear, leading to frequent vibrations and knocking, which can also affect the engine's lifespan.
