The Corolla SOS green light staying on is normal. It indicates that the vehicle's emergency call function is in an online state. Activating self-check function: After parking and turning off the engine for 5-10 minutes, without pressing the brake pedal, press the start button once, or without depressing the clutch, turn the key halfway to the 'on' position. The vehicle will initiate self-check function after powering on. Wait for 5-10 seconds and observe whether the warning lights on the dashboard turn off, leaving only the engine warning light. 4S shop or repair shop inspection: If other warning lights remain on, it's necessary to have the corresponding modules and components inspected at a 4S shop or repair shop. If only the engine warning light stays on, restart the engine and observe whether the engine warning light remains illuminated. If the engine warning light turns off, there's no issue. If the engine warning light continues to stay on, it's necessary to have the engine-related components and modules inspected at a 4S shop or repair shop.

I've been driving a Corolla for several years, and I must say it's a bit odd that the SOS green light stays on constantly. Generally, the SOS system is the vehicle's built-in emergency call function, and the green light should indicate that the system is on standby or connected properly. However, if it stays lit without blinking, it might indicate a system issue. For instance, my car once had a similar problem, and after checking at the 4S shop, it turned out to be poor contact in the control module or unstable battery power, affecting overall performance. This reminds us to pay attention to regular checks while driving, especially before long trips. It's best to refer to the user manual or the car's connected app to confirm if the system is activated or malfunctioning. In short, don't take it lightly—the SOS function could be a lifesaver in emergencies. I recommend taking the time to visit a professional repair shop for an inspection to prevent minor issues from turning into major problems.

Which One is the Brake, Accelerator, and Clutch?

In a manual transmission car, the three pedals from left to right are the clutch pedal, brake pedal, and accelerator pedal. In an automatic transmission car, the left pedal is the brake pedal, and the right pedal is the accelerator pedal, with no clutch pedal. Manufacturers designed this layout based on ergonomics to ensure drivers can react quickly in emergencies. Note: These two pedals should only be controlled with the right foot; never use the left foot to control one pedal. Precautions for controlling the accelerator: When pressing or releasing the accelerator pedal, apply gentle force, ensuring smooth and gradual movements. Select an appropriate gear to keep the engine running mostly at medium speed and with a larger throttle opening to save fuel. Releasing the clutch should be closely coordinated with pressing the accelerator, with swift actions. Before stopping or turning off the engine, first release the accelerator pedal and avoid suddenly revving the engine in neutral. Braking precautions: Press the brake pedal gradually, avoiding sudden braking to prevent the car from jerking forward. Brake early, maintaining a safe distance from the car ahead, and anticipate road conditions to brake in advance. For long downhill slopes, use the automatic parking system as an aid to prevent excessive brake pad temperatures. When braking during a turn, slow down by pressing the brake before entering the turn, then coast through the turn and accelerate out of it. On rainy days or gravel roads, use intermittent braking (pump the brakes) to prevent the car from skidding. Precautions for new drivers: Check tires before driving: Tires are the only part of the car in contact with the road. Poor tire conditions can lead to blowouts at high speeds, endangering safety. Drive at a steady speed as much as possible. Avoid sudden deceleration or acceleration, giving surrounding cars ample time to adjust. Always signal before overtaking. Use flashing high beams, honking, or other signals depending on road conditions to alert the car ahead. Do not follow too closely, as sudden braking by the car ahead can easily cause accidents. Do not use your phone while driving. If you miss an exit on the highway, never reverse or stop.

Is 20 liters per 100 kilometers considered high fuel consumption?

20 liters per 100 kilometers is considered high fuel consumption. Here are some explanations about vehicle fuel consumption: Impact of temperature on fuel consumption fluctuations: This is a normal phenomenon. Generally, in winter when temperatures are low, fuel consumption increases slightly, almost comparable to fuel consumption when using air conditioning in summer. This is because lower temperatures cause the engine to dissipate more heat. Vehicle not maintained for a long time: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil results in poor lubrication, increasing resistance in the engine's moving parts, which requires more energy to overcome, thus raising fuel consumption. Insufficient tire pressure: Insufficient tire pressure increases the contact area between the tires and the ground, leading to higher friction, which means greater driving resistance and increased fuel consumption.

Will Bird Droppings on Car Glass Damage It?

Generally not, but if bird droppings are left for a long time, they may leave hard-to-remove marks after cleaning. These marks cannot be wiped off with water or cloth. Never use fingernails or other sharp objects to scrape them off, as this may damage the paint. The best method is to soak the droppings with water to soften them and then rinse them off with a strong stream of water. The benefits of car window tinting are as follows: Heat and Sun Protection: Tinting can effectively block a large amount of heat generated by infrared rays. UV Protection: Medium and long-wave ultraviolet rays can penetrate thick glass, but applying a heat-insulating film can block most UV rays, preventing skin damage and reducing the aging of car interiors. Safety and Explosion Protection: The base layer of the film is made of polyester, which is highly resistant to tearing and puncturing. Combined with the adhesive layer, the film enhances the glass's strength, preventing injuries caused by accidental glass breakage. Creating a Private Space: By choosing the right type of film, the interior of the car becomes difficult to see from the outside while maintaining visibility from the inside, ensuring privacy and safety. Reducing Air Conditioning Fuel Consumption: Applying a heat-insulating film compensates for the loss of air conditioning cooling capacity, quickly lowering the interior temperature and saving fuel to some extent. Anti-Glare: Reduces accidents caused by glare.

How Long Does It Take to Get a Damage Assessment Report at a 4S Shop?

The time required for damage assessment at a 4S shop depends on the extent of the vehicle's damage. If the damage is minor, the assessment can usually be completed within a day. If disassembly is needed, it may take around two days. Vehicle Damage Assessment Process: Report the Accident: First, report the accident. The insurance company's surveyors need to determine the liability for the accident based on the scene. Therefore, after a traffic accident, the vehicle owner must not leave the scene and should promptly protect the accident site. After the insurance company surveys the scene, they will assess the damaged vehicle and arrange for repairs. Submit Required Documents to the Insurance Company: Required documents include: Traffic Accident Liability Determination Certificate, Mediation Agreement, Judgment Document, Repair Invoice, Medical Expense Invoice, Medical Records, Proof of Lost Wages, Policyholder's Identity Information, Policy, Copy of ID Card, Copy of Vehicle License, Copy of Driver's License, etc. These documents should be submitted to the insurance company for claim calculation. Receive Insurance Compensation: The insurance company will notify the policyholder to collect the insurance compensation. The recipient must bring relevant documents, including the original policy, the insured's original ID card or household registration booklet. If someone else is authorized to collect the compensation on behalf of the insured, the authorized person must bring their ID card and the "Authorization Letter for Claim Collection" issued by the insured.

Why is there a jerky feeling when an automatic transmission shifts up?

Jerky feeling is caused by a mismatch between the engine and vehicle speed. While driving, consciously release the accelerator pedal before shifting, and the transmission will respond immediately and complete the shift automatically. Then, press the accelerator again to enter a higher gear. The biggest advantage of driving an automatic transmission vehicle is its high convenience, as the vehicle does not require manual gear shifting. Here is additional information: Detailed explanation: Transmission shift jerkiness can be considered a normal situation and there is no need to worry. The main reason for this issue lies with the transmission itself. Structurally, whether it's an AT or CVT transmission, they all rely on electrical signals for shifting and recognition. Shift jerkiness occurs when the transmission breaks the original inertia during the process of switching between two different gears, and the sudden force generated reacts back on the vehicle body, causing the jerky sensation.
