1, yellow triangle symbol with an exclamation point in the middle:
This index is TCS (driving force, namely ground adhesion control system) index. Generally speaking, this light will flash when TCS is working. If it is on all the time, it means there is something wrong with attacking TCS. Sometimes the light is on all the time, and then it returns to normal after the flameout and restart;
2. Yellow brackets, with an exclamation mark in the middle: 100. This indicator light is a tire pressure monitoring indicator light, indicating that a tire pressure in the car is insufficient. Please go to the tire shop or 4S shop to check the tire pressure;
3. Yellow gear, with an exclamation mark in the middle: This is an automatic transmission fault warning light, indicating that the gearbox is faulty or the gearbox lubricating oil is below the normal range, or the lubricating oil should be replaced.
The following figure shows the name of the fault lamp and the corresponding icon.
trouble lamp
Engine failure indicator lamp is indicated by checking engine or MIL, and it has two states and indicating contents. One is always on, indicating that the engine electronic control system is faulty; The other is flashing, indicating that the fault is still affecting some performance of the engine (such as exhaust emission). ).
Replace the lubricating oil indicator.
The indicator light for changing the lubricating oil is "oil change". For example, the "oil change" light on the dashboard of Buick Touring Car lights up to remind the driver that it is time to change the oil. After the oil change, the indicator light should be "zero".
Temperature warning lamp
Due to the installation of three-way catalytic converter in modern cars, the exhaust temperature has increased, but too high exhaust temperature is easy to damage the three-way catalytic converter, so this kind of cars are equipped with exhaust temperature alarm devices. When the exhaust temperature warning lamp is on, the driver should immediately slow down or stop. When the exhaust temperature drops, the warning lamp will automatically go out (but after the fuse exhaust temperature warning lamp is on, it will remain on unless it is adjusted or maintained). If the exhaust temperature is high, it will always be open.
Brake warning light
The brake warning light is red with a "!" In the circle. Symbol. If the red brake warning light is on, it means that the braking system has one of the following conditions:
(1) The brake friction plate is seriously worn;
(2) The brake fluid level is too low;
(3) The parking brake has been tightened (the parking brake switch is closed);
(4) Under normal circumstances, if the red brake warning light is on, the ABS warning light will also be on at the same time, because when the conventional brake system fails, the ABS system cannot play its due role.
Warning light with unfastened seat belt
Warning lights that are not fastened with seat belts are represented by a figure (diagonal seat belts on the passenger's chest). After the ignition switch is turned on, if the driver is not wearing a seat belt, the warning light will light up to remind the driver to fasten his seat belt. If the seat belt is not fastened, the alarm lamp will not light up under any circumstances. Check whether the fuse of the lamp is blown, whether the bulb is burnt out and whether the line voltage meets the requirements.
Danger warning light
Danger warning lights are used to warn other vehicles and pedestrians in case of major automobile failure or emergency. The danger warning signal is indicated by flashing the front, rear, left and right turn signals at the same time.
Danger warning lights are controlled by independent switches and usually share a flasher with the turn signal lights. When the hazard warning light switch is turned on, the turn signal circuits on both sides are turned on at the same time, and the front, rear, left and right turn signals and left and right turn signals on the instrument panel flash at the same time. Because the hazard warning light switch connects the flasher with the battery, the hazard warning signal can also be used when the ignition switch is turned off and the vehicle stops.
