SVS light illumination indicates that the engine control unit has detected an erroneous signal from a certain sensor or that it has exceeded the usage standard. When the powertrain self-diagnosis identifies an abnormality, it will use the SVS light to alert the user to inspect and repair the vehicle. The SVS light alarm may originate from the engine, transmission, or gear shift operation. If the SVS light indicates a fault, diagnostic equipment should be used for inspection and repair, and prolonged driving is not recommended. If the SVS light turns off after being on, fault analysis can still be performed using freeze frame data. It is advisable to visit a repair shop for inspection or maintenance. Poor engine combustion, engine knocking, low-quality fuel, unclean engine cylinder interiors, carbon deposits, or the inability of the electronic control unit to obtain engine data can all lead to vehicle malfunctions.

How to Use the Cruise Control in the Verano?

When the vehicle speed reaches above 40 km/h, press the "Cruise Control" button, then press the "SET-" button. Below is the relevant information: 1. Setting the cruise speed After the system is activated, when the car reaches the desired speed, press the "SET" button once to maintain that speed continuously. After setting the cruise speed, you can still accelerate using the accelerator pedal as usual. When you release the accelerator pedal, the system will restore the speed to the set cruise speed. 2. Reducing the cruise speed Press the "SET" button to decrease the speed by 1.5 km/h; if you hold the button, the car will continue to decelerate. Once you release the button, the current driving speed is stored in the memory. If you release the "SET" button when the speed is below 40 km/h, the stored value will be deleted. If necessary, you can use the "SET" button to reset the cruise speed when the speed exceeds 40 km/h.

What are the symptoms of a faulty fuel injector?

Fuel injector failure can directly cause abnormal phenomena in the engine. The symptoms of a faulty engine fuel injector include: 1. Black smoke from the exhaust pipe. 2. Uneven operation among cylinders, with noticeable engine vibration. 3. Decrease in engine power. 4. The vehicle lacks driving force. Additional information: To diagnose a faulty fuel injector, let the engine idle and perform a fuel cut-off test on each cylinder one by one. When the fuel injector of a specific cylinder stops supplying fuel, observe the engine's operation and sound. If the exhaust no longer emits black smoke after the fuel cut-off and the engine speed changes, it indicates a faulty fuel injector in that cylinder. Once the faulty fuel injector is accurately identified, remove it and test it on a fuel injector calibration bench.

Can an automatic transmission car be started in P gear?

An automatic transmission car can be started in P gear. Starting in P gear and then passing through R gear without stopping will not cause additional damage to the transmission. Therefore, in daily driving: You can directly start the engine in P gear, as long as you ensure not to stay in R gear, it will not cause extra harm to the transmission. Additional information: 1. The gears of an automatic transmission are P, R, N, D. In P gear, the automatic transmission is in neutral, and a mechanical lever locks the output shaft to prevent the car from rolling. Of course, the gear lever should only be placed in P gear when the vehicle is completely stationary. 2. R gear, the reverse gear, should only be engaged or disengaged when the vehicle is completely stationary, otherwise it will cause premature wear of the automatic transmission. If you need to push or tow the vehicle, you must use N gear. When towing the vehicle, the towing speed should not exceed 50km/h, and the towing distance should not exceed 50km, otherwise it will damage the planetary gear mechanism of the automatic transmission.

What are the symptoms of aging spark plugs?

Symptoms of aging spark plugs include: difficulty starting the engine, reduced power, excessive exhaust emissions, and increased fuel consumption. Steps to replace spark plugs: Open the hood, lift the plastic engine cover, remove the high-voltage ignition wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure everything is cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires in the correct firing order and reattach the cover. Methods to determine if a spark plug is damaged: Remove the spark plug and inspect its appearance. A normal spark plug's insulator skirt and electrodes should appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burning. If the spark plug is covered in oil or deposits but is otherwise undamaged, it can be cleaned and reused. If the spark plug is severely damaged—showing signs of blistering, black streaks, cracks, or melted electrodes—identify the cause of the damage, fix the issue, and replace the spark plug. Additionally, if the spark plug appears blackened as if smoked, it indicates the wrong heat range was selected or the air-fuel mixture is too rich, possibly due to oil leakage.
