Lang lang frequently asked questions

Frequently asked questions 1: The steering wheel becomes heavier.

Check whether the tire pressure is normal and whether the tire is excessively worn.

The booster pump does not work, and the front wheel air pressure is low.

The booster oil of cold car is thicker in winter, and the direction will be heavier in winter.

Check the steering oil.

1, there should be something wrong with the booster system or booster oil.

2. If you feel that the steering wheel is tight and the car leans to one side during driving, you need to check the tires or balance the wheels. Timely maintenance when these problems are just discovered can prevent the fault from expanding and avoid greater losses.

FAQ 2: Steering wheel failure

When the steering wheel suddenly fails, first of all, keep a cool head and don't panic! Slow down and stop! When foot braking is easy to make the direction out of control, we can use combined braking. Generally speaking, it means to step on the brakes and downshift from high to low, and of course, downshift in turn. For example, if the car is in 5th gear, 4000 rpm, hold the brake tightly, depress the clutch and retreat to 4th gear at the same time, and then release the clutch to the contact point. This completes the combination braking of downshifting. If the speed is high, you can downshift for the same reason, and so on. Downshifting in turn can stop the vehicle. Grab or hand brake to assist parking! Never slam on the brakes!

The steering column is broken, the harness connector of the control system has poor contact, the system fuse is blown, the relay is damaged, and the controller, motor or sensor is damaged.

Frequently asked question 3: B-pillar is abnormal, and the sound is not glass! Not a seat belt buckle! Not plastic! It is the three-layer iron sheet inside, which is a common problem of modern cars and lacks solder joints. It is said by technicians that the lack of modern solder joints leads to the tight fit of the car body and the sound of friction. Remove the seat belt assembly and pour foam glue into it.

FAQ 4: During this period, I basically ran to the city, turned on the air conditioner, and ran almost 300 kilometers with 200 mosquito-repellent incense oil. In the past, I ran the whole high speed, which was almost 0.35/ km, but now it is basically 0.7/ km, which is twice as much. Just asked a friend about his Honda SUV, with a displacement of 2.0 and an automatic transmission of 0.7/ km. I searched Du Niang, and some people say that D gear is more fuel-efficient in urban areas.

Answer: Manual shift, manual shift in advance, high-grade low-speed or high-grade high-speed all save fuel.

If you don't manually add gears, you can completely rely on the D gear to move up to the second gear by 20Km and the third gear by 30Km.

I haven't had time to speed up, and I have to step on the brakes, which costs oil.

Driving in urban areas, manual+/-gear, fast starting speed, fuel saving!

Watching taxi drivers drive manual gears, starting from scratch, often overtaking is not fast, mainly to save fuel and time.

FAQ 5: There are squeaks and collar noises when reversing today. Is it normal? Or where is the problem and how to solve it?

Answer: 1. The car was washed or rained the day before. Generally, when the car is reversing cold, many cars will have abnormal noise, which is called abnormal brake noise. It may be that some barbs on the brake pads and brake discs interfere with the brake pads, which can be ignored and disappear naturally after a short period of normal driving.

2. It is estimated that there is no synchronizer in reverse gear. Synchronizer is a device inside the gearbox, which plays the role of meshing gears smoothly when we shift gears. Some cars have no synchronizer, so it is not easy to shift gears. In addition, in order to distinguish it from the forward gear, the reverse gear of most cars has no synchronizer, which is why it is more difficult to engage the reverse gear than other gears, and sometimes there will be abnormal noise when engaging the reverse gear.

Frequently asked questions 6: 20 15 I ran more than 2 100 kilometers and stopped for more than three hours. When you get out of the car and step on the brakes, the brake pads will squeak. After stepping on the brakes several times, the abnormal noise disappeared. Please help me. I am a novice. I don't know anything. Thank you!

A: It was raining or washing the car the day before. Generally, when the car is reversing cold, many cars will make abnormal noises. This is called abnormal braking noise. It may be that some barbs on the brake pads and brake discs interfere with the brake pads, which can be ignored and disappear naturally after a short period of normal driving.

FAQ 7: Today, it rained heavily. The water on the road was so deep that the car in front suddenly turned off. I couldn't rush over and stopped the car. I turned off the car manually and there was no second fire. I asked some friends to push the car to the side of the road.

Now I would like to ask if there is any problem if the engine is turned off manually instead of automatically turning off the vehicle.

A: There shouldn't be much problem. Extinguishing by immersion is different from self-extinguishing. It's like you put out the fire in the cooking stove with water, and it's gone. If you turn it off yourself, it will catch fire. However, it is best to check whether there is water in the air intake system.

FAQ 8: About the defogging function in rainy days.

Ways to avoid fogging the window:

Method 1:

Spraying antifogging agent and other preventive measures. Spray a little defogging agent on the window, then wipe it clean to remove dirt and spots on the window. When polishing glass, forming a thin transparent protective film on the glass can effectively prevent the fog layer formed by water vapor condensation on the glass, especially in cold winter. Other anti-fogging agents that can be replaced are detergent, soapy water, glycerin, alcohol or salt water. After drying, use suede or soft dry cloth to wipe off the excess fiber, which can ensure that the automobile glass will not fog in a few days.

Method 2:

Air conditioning refrigeration method. Using the refrigeration and dehumidification function of air conditioner, fog and steam can be removed by reducing air humidity. In summer, especially after many people enter the car, if they don't turn on the air conditioner in time, the gas exhaled by people will be wet, and soon the front windshield will be foggy. At this time, you can turn on the air conditioner and blow cold air against the front windshield, and use the dehumidification function of the air conditioner to slightly remove the fog and steam on the front windshield. However, if the humidity is too high and the air conditioning effect is not obvious, you can open the window a little and quickly reduce the humidity in the cab. Of course, it can also be used with air conditioning, and the effect will be faster.

Method 3:

Air conditioning and warm air method. By reducing the temperature difference.

FAQ 9: Self-esteem of 2065438+20061month. There were many abnormal noises before, which solved many problems. There is an abnormal noise under the armrest box now. When the armrest box sounds abnormally, the left B-pillar doesn't ring, and when the left B-pillar rings, the armrest box doesn't ring. Go to the 4S shop and ask the master to repair it. The master sat in the passenger seat and pushed the armrest box to my driver's seat. It won't ring right away, and neither will the B-pillar. Later, the thin solder joint inside the armrest box was knocked with an awl, and the place where the screw was fixed was padded. Still can't solve it. Just push the armrest box and it won't ring. Just push it gently and it won't ring.

You can try putting a sponge in the gap.

Frequently asked questions 10: Lang Lang's air inlet hose is broken.

A: This is a design problem of Lang Lang. The broken part is too short. When the fuel is supplied, the engine will shake and crack easily after a long time. Replace the intake pipe and clean the lower throttle. Because the engine is easy to accumulate dust after cracking, it is necessary to clean the throttle.
