What does the exclamation mark on the car indicate?
2 Answers
There are approximately three types of exclamation mark warning lights that may appear on the car dashboard: 1. A triangle with an exclamation mark in the middle, which is a general fault indicator light. 2. A circle with parentheses and an exclamation mark in the middle, which is the brake system warning light. 3. A horizontal line with parentheses and an exclamation mark in the middle. This is the tire pressure monitoring warning light, which illuminates when the air pressure in one of the vehicle's tires is too low. Reasons why the brake system warning light may illuminate: 1. In some cars, it lights up for a few seconds after turning on the ignition and turns off after starting the engine. 2. It lights up when the handbrake is engaged and turns off when released. 3. Low brake fluid level, which may illuminate while driving. 4. A malfunction in the brake system causes it to light up.
I've been driving for years, and every time that yellow exclamation mark light pops up on the dashboard, it makes me nervous because it's usually the tire pressure warning reminding me. Last time when I was in a hurry, I encountered it and immediately pulled over to check the tires, finding that the right front tire had low pressure, possibly punctured by a nail. After inflating it, the light went off. But be careful, if it's a red exclamation mark, it's more dangerous, possibly indicating a brake system failure, such as insufficient brake fluid level or ABS issues. After stopping, I first manually measure the tire pressure to see if there's any obvious damage. If everything seems normal but the light remains on, I head straight to the repair shop without hesitation—road safety is no joke. It's good practice to check tire pressure and brake conditions monthly, especially during seasonal changes, to avoid unexpected troubles.
