What does the red exclamation mark in the car mean?

Red exclamation mark (specifically a circle with an exclamation mark inside parentheses), this represents a warning for the braking system, mainly indicating a brake system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the braking system is required to avoid accidents. Apart from the red exclamation mark indicating a brake system fault, all other exclamation marks in a car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Main issues include parking sensor faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, etc. 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. This is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant below the normal range. Transmission oil should be replaced promptly. Abnormal Tire Pressure: A horizontal line under parentheses with an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating a fault in the car's lights. Solution: Visit a 4S shop as soon as possible for inspection and repair. You can also check by yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights, to identify the problem.
A while ago, I also encountered the red exclamation mark lighting up while driving, and I was completely stunned at the time. I quickly pulled over to check the vehicle manual and realized that it was usually a warning for the braking system—possibly the handbrake wasn't fully released or the brake fluid was low. Upon inspection, I found that the brake fluid reservoir level was below the minimum mark, so I promptly bought the correct specification of brake fluid and topped it up, and the warning light disappeared. This kind of alarm should never be ignored. Last time, my neighbor Old Wang kept driving with the light on, and his brakes became stiff, nearly causing a rear-end collision. I suggest you stop immediately to check—don’t gamble with safety. If you can’t figure it out, call a tow truck.
A red exclamation mark popping up on the dashboard basically means your car is screaming that there's a problem. The most common cause is the handbrake not being fully released - try pressing it down completely first. If the light remains on, immediately check the brake fluid reservoir; there are level markings on the cap. If the fluid is below the minimum line, it's likely either a leak or severely worn brake pads. It could also be related to the ABS system, which may affect braking distance. With over twenty years of driving experience, I've encountered this several times - each instance required pulling over to investigate, never daring to continue driving recklessly. Remember, abnormal tire pressure can also trigger similar warnings.
When repairing cars, we often encounter owners asking about the red exclamation mark. This symbol is usually triggered by the vehicle's alarm system and has the highest priority. Focus on checking the braking system: first, confirm whether the handbrake is fully released; then check if the brake fluid is sufficient—the reservoir is located on the left side of the engine compartment; finally, inspect the thickness of the brake pads. This light may also illuminate when there is a power steering failure or insufficient engine oil pressure. It is recommended to immediately stop in a safe area. If you are unable to perform the inspection yourself, contact a repair shop directly by phone. Do not attempt to drive slowly to the repair shop—there are too many cases of accidents occurring.
