What does it mean when the car shows an exclamation mark

An exclamation mark appears in the car to indicate:

1. Tire pressure indicator.

When we start the ignition, this tire pressure indicator light will light up and the car will perform a functional self-check, which will automatically turn off after a few seconds.

Second, the lighting fault indicator.

If this exclamation mark indicator appears, it means that the exterior bulb is faulty and needs to be repaired promptly.

3. Steering system fault indicator.

If this red exclamation mark lights up, it means that the electromechanical steering mechanism may not work or the steering column lock is broken, and can not continue to drive at this time, and needs to be repaired and troubleshooting in time to avoid unnecessary accidents.

Fourth, the brake system fault lamp.

If this is red, you need to pull over to check for faults, or drive at low speeds, and be ready to brake at any time. Otherwise, the braking force will be insufficient.

5. Water temperature alarm light.

If this exclamation point situation occurs, do not continue to drive so as not to burn out the cylinder and pay a terrible price. The water temperature alarm may be caused by a fan stopping, or a broken thermostat or water pump that prevents the coolant from circulating.

If you can't solve it yourself, it's best to call rescue, open the hood to assist in heat dissipation, and avoid scrapping the engine, so after knowing what the exclamation mark of the car means, be sure to deal with it properly, don't open it blindly, and avoid unnecessary trouble.

When the car starts, the car will carry out self-inspection, the tire pressure indicator light will be functional detection during the self-test, and the light will automatically go off after 2-3 seconds, during driving, if the tire pressure indicator light is lit, it means that there is a problem with the tire pressure of the car, and the tire condition needs to be checked, if there is no problem with the tire inspection, you can press the reset button to reset.

If the lighting failure light is on, it means that the headlight of the car is faulty, and a bulb may be damaged; When the steering system fault indicator light is on, it is possible that the electromechanical steering mechanism does not work or the steering column lock fails, and can no longer continue to drive at this time, and danger is easy to occur; The brake system fault light is on, indicating that the brake system is faulty or the fluid level of the brake system is too low.

If it is in the process of driving, you must pay attention, always be ready to step on the brakes, and the gearbox fault light is on, indicating that the gearbox is abnormal, and you should go to the repair shop for maintenance in time; The wiper fault light is on, indicating that the wiper system is faulty, it may be that the parts of the wiper are damaged, or the wiper is not working.

Obviously, if the indicator light with an exclamation mark appears on the dashboard, it means that there must be an abnormality or fault in the corresponding part of the car.

The exclamation mark light is generally due to the following reasons: 1. The battery of the remote control key is low, 2. The door compartment is not closed properly, 3. The transmission of the automatic transmission model is faulty. 4.Individual alternative cars also have to check the braking system.

It represents the alarm light of the replication system. This light illuminates when the brake lever (i.e. handbrake) is pulled. When the handbrake is lowered, the indicator lights off automatically. On some models, this light will turn on when the brake fluid is insufficient.

The main conditions may be as follows: the light is on, and the dry dual-clutch transmission clutch overheats; Intervention or failure of the oil shut-off system; Parking sensor failure; malfunction of exterior lights; faulty engine oil pressure sensor; Driver anti-slip system warning or malfunction.

There are five situations in which a car displays an exclamation point, which are:

1. The exclamation mark in the middle of the red triangle, which is called the conventional fault light, will light up when the vehicle fails, and the common fault problems are oil supply system failure, sensor failure, lamp failure, etc.;

2. There is an exclamation mark in the middle of the horizontal under the yellow brackets, which is the tire pressure monitoring warning light, only when the air pressure of the four tires of the vehicle is unbalanced or too low, it will light up, and the tire pressure needs to be manually reset after re-checking;

3. Red bracket round exclamation mark, this is called the braking system warning light, when the handbrake is pulled, the braking system warning light will light up, in addition to the light may be because the braking system is faulty, the braking system liquid level is too low, at this time it is recommended to drive at low speed, and be ready to brake in advance, and increase the pedal pedal force;

4. The exclamation mark in the yellow bulb, this is the failure indicator of the lamp, when the indicator light is lit, it means that the lamp bulb is faulty, and it is recommended to replace the bulb;

5. The exclamation mark next to the red steering wheel, this is the steering system fault indicator, when the light is on, it means that the steering power system is faulty or not working, the steering wheel is locked and other problems, and you need to go to a 4S shop or maintenance shop for maintenance.

There are about three kinds of exclamation mark warning lights on the dashboard of a car:

1. There is an exclamation mark in the middle of the triangle, which is a conventional fault display light.

The main conditions are as follows:

1. The clutch of the dry dual-clutch transmission is overheated;

2. The oil cut-off system intervenes or fails;

3. Parking sensor failure;

4. External lamp failure;

5. Engine oil pressure sensor failure;

6. Warning or failure of drive anti-skid system.

2. There is an exclamation mark in the middle of the bracket circle, which is the warning light of the braking system, which will light up in the following situations

1. Some cars light up for a few seconds after turning on the ignition switch, and turn off after starting the engine;

2. It lights up when the hand brake is pulled up and goes off when it is put down;

3. The brake fluid level is too low, and it lights up during driving;

4. The brake system is lit up in case of failure.

3. There is an exclamation mark in the middle of the horizontal line below the parentheses. This is a tire pressure monitoring warning light, which illuminates when the air pressure of one of the vehicle's tires is too low.

One is: the handbrake is pulled up and will be displayed.

The second is: the tire pressure monitoring alarm will be displayed.

When the tire pressure warning light is on, it is best to stop first to check what is causing the tire pressure problem.

After all, the problem of tires is a serious problem, and once a tire burst, the consequences can be imagined.

1. "Parenthesis exclamation point".

Tire pressure alarm symbolIf the sign only appears during the vehicle self-inspection, you don't need to pay attention to it, if it has always existed, you should get out of the car in time to check the tire pressure to see if there is a problem with the tire pressure.

2. "Circular exclamation mark".

Brake warning light, indicating that the brake pads are badly worn. If the brake is tapped, accompanied by a sizzling sound of "iron rubbing iron", you need to consider whether the brake pads have reached the limit.

Tire pressure alarm red warning light. There is an exclamation mark in the middle of the brackets and a pattern at the bottom, just like the pattern of a tire. The whole icon is like a planing diagram of a tire.

The tire pressure light is on, indicating that the tire pressure of the car is too low, and it is prone to the danger of puncture, which may be due to tire wear, loopholes, etc., and should be immediately repaired to a 4S shop or repair shop. Driving safety is no small matter, do not delay.

Car tire pressure precautions.

The tire pressure of cold and hot tires is not the same, so pay special attention when measuring it. In general, hot tires have about higher pressure than cold tires. On weekdays, the standard tire pressure we usually refer to is the cold tire pressure, and if the hot tire pressure is measured, it is the cold tire pressure value.

According to different seasons, the tire pressure should also be properly adjusted, the difference between air temperature in winter and summer will expand and contract, and the tire pressure in winter should be a little higher than in summer. Generally, in winter, the standard air pressure of automobile tires shall prevail, and the appropriate increase shall be made. In summer, it is adjusted according to the lower limit of the standard air pressure of automobile tires to prevent high temperature punctures.

This sign is a malfunction of the car's braking system, which can be excessive brake pad wear, damaged sensors, insufficient brake fluid, etc. It is recommended to first see if the brake fluid is below the standard, if the brake fluid is normal, if your car has been used for tens of thousands of kilometers and has not changed the brake pads, it may be that the brake pads are worn out beyond the standard, it is recommended to replace, if these two problems are not, it may be a problem with the sensor, or other problems, it is recommended to go to the 4S point to check, the braking system is a big problem, you must pay attention to it! Hope it helps.

Hello. This should be a brake fluid level alarm.

There are three cases of a yellow triangle exclamation mark on a car dashboard:

1. Yellow triangle sign, an exclamation mark in the middle, this is the driving force indicator, that is, the ground adhesion control system indicator. When the drive force indicator light is on, it is a reminder that the owner needs to turn off the drive force control system. If this light is always on, there is a problem with the drive system.

2. Yellow brackets, an exclamation mark in the middle, this indicator is the tire pressure monitoring indicator. The tire pressure indicator light is on to indicate that the tire pressure is insufficient.

3. Yellow gear, an exclamation mark in the middle, this is the automatic transmission fault warning light, indicating that the transmission is faulty or the transmission lubricating oil is lower than the normal range, or the lubricating oil needs to be replaced.

This is a tire pressure failure light, whether there is a tire pressure gauge on your car can measure it to see if there is any abnormality, and then do the lower tire pressure reset.

The first exclamation mark is the exclamation mark in the middle of the red triangle, which is called the conventional fault light, when the vehicle fails, it will light up, common fault problems are, clutch overheating, fuel supply system failure, sensor failure, lamp failure, drive anti-skid system warning or failure, etc.;

The second kind of exclamation mark is a red bracket round exclamation mark, which is called the braking system warning light, when the handbrake is pulled, the braking system warning light will light up, in addition to the light may be because: the braking system failure, the braking system fluid level is too low, then it is recommended to drive at low speed, and be ready to brake in advance, and increase the pedal pedal force at the same time;

The third exclamation mark is an exclamation mark in the middle of a horizontal under the yellow brackets, which is a tire pressure monitoring warning light, which will only light up when the air pressure of the four tires of the vehicle is unbalanced or too low, and after re-checking the tire pressure, it needs to be manually reset;

The fourth exclamation mark is the exclamation mark in the yellow bulb, which is the light failure indicator, when the indicator light is on, it means that the car light bulb is faulty, and it is recommended to replace the bulb;

The fifth exclamation mark is the exclamation mark next to the red steering wheel, which is the steering system fault indicator, when the light is on, it means that the steering power system is faulty or not working, the steering wheel is locked and other problems, and you need to go to a 4S shop or repair shop for maintenance.

The red exclamation mark icon mostly refers to the warning light of the braking system. It will light up in the following situations:

1. The car will light up for a few seconds after turning on the ignition switch, and turn off after starting the engine.

2. It lights up when the handbrake is pulled up and brakes, and turns off when it is put down.

3. The brake fluid level is too low, and it lights up during driving.

4. Be cautious when the braking system fails.

Troubleshooting direction:

1. It may be that the brake pads are seriously worn, and the brake pads are divided into two kinds of induction wires and without induction wires. Brake pads without induction wires will not automatically alarm, but the sizzling sound of "iron rubbing iron" will tell you that the brake pads need to be replaced.

2. It may be that the brake fluid level is too low, the brake fluid plays a vital role in the braking system of the car, when the driver steps on the brake pedal, the force of stepping down from the pedal, by the piston of the brake master cylinder, transmits energy through the brake fluid to the brake cylinder of the wheel, so that the brake pad is in contact with the wheel, so as to achieve the purpose of stopping the vehicle from moving forward.
