The lock sound of the Tank 300 can be adjusted by pressing the unlock and lock buttons on the remote key simultaneously for 3 seconds. If you want to adjust the car lock sound, press and hold the unlock and lock buttons on the remote key for 3 seconds at the same time, and the setting is successful.
1. Correctly distinguish between normal and abnormal sounds.
When the car is running, the vibrations of various mechanisms will make sounds of different kinds, but the sound does not mean that the car is defective. In order to avoid unnecessary disassembly, you must first distinguish what is normal. abnormal sounds and sounds. Normal vibrations of various system components (such as noise on the engine surface), gear impact noises when changing gears, intake and exhaust noises using gas as a work source, Lnoises of gears meshing, etc. are all normal sounds. Abnormal noises (abnormal noises) can be divided into light noises, normal noises and malignant noises according to their impact on car performance. Slight noises, such as the flashing sound of high-voltage electrical leakage, the slight rolling noise of bearings, etc., are generally small in volume, the degree of wear of the parts is not large, and it does not There is no significant change for a long time. Such defects can still keep the car without repair normal driving.
3. When diagnosing abnormal car noises, attention should be paid to creating good auscultation conditions and trying to eliminate interference from other noises so as not to affect the accuracy of judgment.
It is best to consciously amplify or reduce the sound, that is, use a screwdriver or other metal rod toMs. stethoscope to contact the sound part to amplify the sound, or use a single cylinder to cut off the fire to reduce the sound, to meet the diagnostic needs. The monitoring site must remain quiet to minimize human interference.
3. Below we list some common abnormal car noises that are easy to eliminate along with simple methods of identification and elimination.
1. There are abnormal noises in the body
Symptom description: When you drive and step on the accelerator or when braking, there are always abnormal noises in some parts of the body. The sound is not loud and does not affect normal operation, but there is always a little worry that something is wrong.
Problem analysis: This problem usually occurs because the rigidity of the body is insufficient, causing the vehicle to deform during driving.te, the door and frame rub or shake, or desoldering in some places causes friction between the steel plates. , etc. .
Some cars also have louder wind noise. To some extent this has to do with the shape of the car. In some cars, body parts are not properly secured and may be the cause. abnormal noise. Generally, tighten the screws. This can be resolved.
Solution:
First check whether there are any loose objects in the trunk or on the rear seats that are easy to roll and make sounds, and exclude some items that are not securely attached and emit sounds. . noise.
If you find that the friction between doors and windows causes abnormal noises, you can stick tape on the doors and windows or put rubber on the friction parts. You may be able to reduce or eliminate abnormal noises. , but theresult is only a temporary solution and not the root cause of the problem. If none of the above problems are found, you should go to a regular repair shop for inspection and troubleshooting.
2. There is an abnormal noise in the engine
Symptom Description: There is a higher possibility of abnormal noise in the engine compartment. Most people also rely on the source of the sound. It is an abnormal noise in the engine compartment, which is usually a metallic screech or hiss.
Problem Analysis: Abnormal noise coming from the engine compartment will include a loud whistling sound from the belt, which is usually caused by belt slippage. There will also be a sharp sound of dry rubbing of metal parts when the engine is running, which is usually due to damage to the bearings of the generator, water pump, and power steering pump. If the bsound of an air leak is caused by the engine running, this may be the result of a blocked engine; exhaust system, vacuum tube leak or rupture.
Solution: Abnormal engine noise indicates that the technical condition of a certain engine mechanism has changed. This is mainly due to excessive wear of certain parts or poor assembly and adjustment. Certain abnormal noises can predict the possibility of accidental engine damage. Therefore, when abnormal noises occur in the engine, they should be repaired in time to prevent the fault from extending.
It is worth remembering that if there are abnormal noises in the engine, the car owner is unlikely to be able to solve it himself and it is better to send it to the factory for maintenance.
3. There is an abnormal noise in the gearbox
Explanation of symptoms: If there is a “rusting” noise inside the gearboxgearbox while the car is driving, but it disappears after the clutch or accelerator is depressed, replace it. A whistling sound will be heard when changing gears.
Problem analysis: If the source of the noise encountered while driving is the gearbox, it may be due to wear of the gearbox bearings or gears, or to points rolling. If the transmission makes abnormal noises when shifting at high speeds, the transmission oil may contain metallic powder, indicating excessive wear of components such as the gear belt clutch. brake of the gearbox.
4. There are abnormal noises in the tires
Symptom description: The tires emit rhythmic noises, and the faster the vehicle speed, the higher the frequency.
Analysis problem: When a car tire comes into contact with the ground, it will produce ditowards noises of different strengths and weaknesses depending on the type or irregularities of the road, the speed of the car, the type of tire and the air pressure of the tire itself. Therefore, no matter how perfect a car is, it cannot completely eliminate the noise generated by tires and ground while driving.
5. The engine guard is making an abnormal noise.
Explanation of symptoms: The engine guard has been installed for a while, but after a ride to the suburbs, there was a noise at the skid plate on my back. Strange noise.
Solution: Screws tend to move around in cars that move frequently. If you often hear "pop, pop, pop" noises coming from the air intake grille, in addition to the grille, in addition to the clearance, the car owner should always check whether the skid plate screws of the motor are loose or if the motor protection plate and the bottom plate are looses. If the abnormal noise is caused by loosening, in addition to tightening the screws, some cardboard objects also need to be placed. the abnormal sound area. Abnormal noise can be easily eliminated.
6. Brakes make abnormal noises
Symptom description: The vehicle makes relatively loud noises and abnormal noises when the brakes are applied.
Problem Analysis: Of course, abnormal noise when braking may also be caused by other reasons, such as improper use or deformation of the brake disc material, hardness, porosity, friction characteristics and compression characteristics are not qualified, the brake pads and brake discs are wet and rusty, and the brake pads are damaged. The metal wire in the formula of dynamic friction pads is too hard, and the scraper of mechanical brake friction pads and others reasons. To resolve this problem, simply brake vigorously several times in succession to eliminate the abnormal noise.
6. Brakes make abnormal noises
Symptom description: The vehicle makes relatively loud noises and abnormal noises when the brakes are applied.
Problem Analysis: Of course, abnormal noise when braking may also be caused by other reasons, such as improper use or deformation of the brake disc material, hardness, porosity, friction characteristics and compression characteristics are not qualified, the brake pads and brake discs are wet and rusty, the metal wire in the brake pad formula is too hard, and the mechanical scrapers of the pads brakes are among the reasons. To resolve this problem, simply brake vigorously several times in succession to eliminate the abnormal noise.
Groundution:
The brake pad is one of the most important parts of the braking system. Generally, the lifespan of the front brake pad is 30,000km and the lifespan of the rear brake pad is 30,000km. the brake pad is 30,000 km. The lifespan of dynamic friction plates is 120,000 km. If there is a "squealing" sound when applying the brakes, it is most likely a warning sound coming from the brake pad wear indicator, which indicates that the brake pad brake has exceeded its usage limit. When this happens, car owners should go to the car dealership for maintenance as soon as possible, otherwise the brake pads will be exhausted, causing damage to brake components, abnormal braking effect and accidents.
The method is as follows:
1. Find and collect the water gun. Water guns usually appear fromrandomly in different corners of the map and players must find them on their own.
2. Click the switch gun button to switch from the primary weapon to a water gun.
3. Press and hold the fire button to charge water bombs. After charging is completed, a white mist will be emitted from the mouth of the water gun.
4. Aim at the target and press the fire button to shoot. The water gun has a shorter range, so you need to pay attention to distance and aiming accuracy.
