What Causes the Squeaking Sound When Starting a Jimny?

There are several reasons why a Jimny may produce a squeaking sound when starting: Poor Oil Lubrication: After the car has been parked for a day, the engine's lubricating oil mostly flows back into the oil pan. During a cold start, the oil pump cannot immediately establish oil pressure and form an oil film between components. Especially the valves inside the cylinder head, which do not receive lubrication during a cold start, will have some valve clearance, whether they are hydraulic lifters or mechanical rocker arms, leading to abnormal noise. Charcoal Canister Solenoid Valve Noise: The function of the charcoal canister solenoid valve is to open the solenoid valve between the charcoal canister and the intake manifold after the engine starts. This not only reduces emissions but also lowers fuel consumption. However, abnormal noise may occur during its operation.

Why is the Pedestrian Safety Assist Unavailable?

ACC radar has an issue. You can try to address it and restart the system. If you cannot resolve it yourself, you can visit a 4S shop for inspection. Below is more information about the pedestrian safety assist function: 1. Limitation 1: This system is only an auxiliary tool and cannot detect all pedestrians, cyclists, or vehicles under all circumstances. 2. Limitation 2: The system works best when it detects clear and unambiguous information about a pedestrian's body shape, meaning it needs to clearly recognize information such as the head, arms, shoulders, thighs, and the normal walking pattern of a person. The system can detect pedestrians who contrast with the background (e.g., when the color of the pedestrian's clothing contrasts sharply with the surrounding environment). If the contrast is low, the pedestrian may be detected later or not at all, which means warnings and braking may be delayed or not occur.

How long does it take for fogging in new car headlights to disappear?

As long as you turn on the headlights normally every day, the fog should dissipate in about a week. Causes of headlight fogging: 1. Fogging caused by environmental temperature differences: During the rainy season, on rainy days or in winter, when the headlights are turned off and the temperature inside the lamp assembly drops, water molecules in the air can easily enter the headlight through the rubber ventilation holes. When the internal temperature of the headlight is unbalanced and the temperature difference between the inside and outside of the lens is too large, water molecules from the humid air will gather from the high-temperature area to the low-temperature area, increasing the humidity of these parts. Then, it will condense on the inner surface of the lens, forming a thin layer of water fog. 2. Fogging caused by vehicle wading and car washing: If the vehicle wades through water, the engine and exhaust system, being relatively large heat sources, will cause rainwater to form a large amount of water vapor on them.

What is the fault when the dashboard looks like glasses?

The dashboard looking like glasses indicates that the brake pads are worn thin, triggering the warning line alarm, and new brake pads and warning lines need to be replaced. The interpretation of car dashboard indicator lights is as follows: 1. Red indicator lights: Red lights are generally danger warning lights. If these red indicators light up, they must be checked and repaired promptly, otherwise they will have a huge impact on driving safety or cause significant damage to the vehicle itself. 2. Yellow indicator lights: Yellow lights are fault indicators. When yellow lights on the dashboard illuminate, they inform the driver that a certain system function of the vehicle has been lost. For example, if the ABS warning light comes on, the direct meaning is that the ABS is no longer functioning, which may cause the wheels to lock up during braking. 3. Green indicator lights: Green indicator lights are status indicators, showing what working state the vehicle is in. For instance, the power mode indicator of an automatic transmission or the HINLO of the body height adjustment does not warn the driver but indicates the current state of the vehicle.

What is the normal voltage difference for new energy vehicle batteries?

The voltage difference within the same battery pack should be around 0.5 volts. If it exceeds 0.5 volts, it indicates an issue with the battery cell showing the lowest voltage. The normal voltage ranges for automotive batteries are as follows: 1. For 12V systems: The no-load battery voltage should be around 13 volts, and the load voltage should not be lower than 11 volts to be considered normal. If it falls below this level, starting difficulties may occur. 2. For 24V systems: The no-load battery voltage should be around 26 volts, and the load voltage should not be lower than 22 volts to be considered normal. If it falls below this level, starting difficulties may occur. 3. For charging voltage: In 12V systems, the generator output voltage should be between 13.5-14.5 volts when charging begins. For 24V systems, it should be between 27-29 volts.

Which lane to take when driving to the right front

When driving to the right front, take the straight lane. This is considered a lane change, not a turn. Only right turns should use the right-turn lane. Below is relevant information about traffic signals: 1. Green arrow light: At intersections with arrow traffic lights, observe the direction of the arrow carefully. A right-pointing green arrow only permits right turns from the right-turn lane. However, some lanes allow both straight driving and right turns, so vehicles can also turn right from these lanes. 2. When passing through intersections: When approaching unfamiliar intersections, slow down in advance and observe traffic lights and lane signs. This ensures safe driving. Pay close attention to special signs such as height or weight limits.

What does rec mean on a dash cam?

Dash cam rec is the abbreviation of the English word Recording, meaning it is in the process of recording. Nowadays, dash cams have become an essential safety device for car owners. The functions of a dash cam are as follows: 1. Protecting the legal rights of drivers: In case of a collision with pedestrians crossing the road or cyclists and motorcyclists, drivers might face extortion. A dash cam can provide valid evidence to protect the driver. 2. Quick and accurate accident handling: By reviewing the recorded footage, the responsibility for the accident becomes clear, allowing traffic police to handle the incident swiftly and accurately. This not only enables quick clearance of the scene to restore traffic flow but also preserves crucial evidence from the incident, contributing to a safer and smoother traffic environment. 3. Reduction in accident rates: If every vehicle is equipped with a dash cam, drivers are less likely to violate traffic rules recklessly, leading to a significant decrease in accident rates. Moreover, any vehicle involved in an accident can be captured by other vehicles' dash cams, greatly reducing hit-and-run cases.
