Car lock indicator light not illuminating is caused by either the vehicle failing to successfully complete the locking operation or a malfunction in the anti-theft alert system. 1. Locking operation: The car lock indicator light not lighting up indicates the vehicle did not successfully complete the locking procedure. Some models provide a light prompt when locking - typically the hazard warning lights will flash once. If this lighting system prompt suddenly disappears during locking. 2. Anti-theft system malfunction: The anti-theft system can only complete the locking operation when in the off state. Additionally, some models equipped with push-button start cannot complete the locking operation if the vehicle isn't turned off, even with all doors closed.

Oh, I've encountered this issue too. The lights not turning on when remotely locking the car is actually quite common. First, check if the fuse is blown, especially the one for the car lights. There's usually a location diagram in the manual—open the fuse box and look for the corresponding position. If the fuse is fine, then check if the bulb is damaged. Car light bulbs often fail due to vibration or aging, so try replacing it with a new one. Also, pay attention to whether the remote control battery is dead—simply replacing the battery can solve many problems. Additionally, if the car's voltage is unstable, such as when the battery is nearly dead or the alternator is faulty, it can also affect the normal display of the lights. It's advisable not to wait for major issues to arise. Get the wiring thoroughly checked at a repair shop early on—safety first. Don’t leave without confirming the doors are properly locked.

When Will the Exclamation Mark Light Up?

There are five scenarios when an exclamation mark appears on the car dashboard: general faults, automatic transmission faults, braking system faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these five situations: General Faults: An exclamation mark inside a triangle indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission fault or low transmission lubricant level. Transmission fluid should be replaced promptly. Braking System Fault: An exclamation mark inside a circle with parentheses represents a braking system warning, typically indicating a braking system malfunction or low brake fluid level. Immediate inspection of the braking system is required to avoid accidents. Abnormal Tire Pressure: An exclamation mark below a horizontal line inside parentheses is the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
