1. Passat new car running-in:
For new cars, good running-in (run-in) helps to extend the service life of the vehicle. The initial running-in mileage of Passat is 1500 kilometers (it can be shortened to 1000 kilometers with experience). Car owners should pay attention to the following aspects during the running-in period of a new car:
1. Don't fully open the throttle, step on low throttle based on experience.
2. The speed per hour is limited to less than 3/4 of the maximum speed.
3. Put the engineRotating speedLimit it to 4000 rpm to avoid pulling up the speed.
4. Avoid working with trailers. When some car owners encounter other faulty cars, if the car is still in the running-in period, it is best not to help the trailer, or think of other ways, otherwise the car will be injured.
5. The correct running-in of a new car should be gradual (referring to the engine speed). For running-in under various engine speeds, it should not be used for a long time at an almost fixed engine speed for a long time.
2.Red warning light
Once the red warning light comes on, the vehicle owner must stop and check.publicThere are the following red warning lights for cars:
a.ABSWarning light: light indicatesbrakeIt has been restored to a normal state, that is, the anti-lock brake function has failed. In this case, the car owner should send the car to a professional after-sales service station.
b.Handbrake warning light: namelyBraking SystemWarning light. The light flashes at the same time with a warning sound, indicating that the handbrake has not been released or the brake fluid is lacking.The former will lead to weakened driving power, and isBrake padswithBrake discThere is abnormal wear. If the handbrake has been completely released, but the warning light is still shining, it is sure that the brake fluid is lacking, and you must stop and check. Open the hood, check the brake oil can, first to see if there is a leak, if there is a leak,carDon’t start again, stay where you are and wait for maintenance personnel to deal with it; if there is no leakage, but the brake fluid is slightly below the bottom line, you can drive at a slower speed as appropriate and drive to the nearest maintenance station.
If the handbrake warning lamp lights up together with the ABS warning lamp, it is not only the ABS failure, but also the braking force distribution failure of the brake system. The rear wheels may lock prematurely during braking, and the car needs to be sent to the repair station.
c. DynamoWarning light: The red light is on to indicate that the generator has malfunctioned and is not generating electricity.There are two main reasons for the failure: one is the generatorbeltThere are two ways to detect looseness: listen for abnormal noise; check the generator and press the belt with your hand to see if it is loose. Since maintenance requires professional tools such as tensioners, in this case, it is best to stop driving, and continue driving may cause serious damage to bearings, belts, etc.The second situation is that the belt falls off, ifAccumulatorThere is still electricity in it, so it can be slowed down properly. Because the battery needs to be discharged, the car will mainly turn off unnecessary electrical appliances at this time and drive to the nearest maintenance station. At the same time, the water temperature and oil pressure must be monitored at any time. If abnormalities are found, you should immediately parking.
d. Engine oil warning light: Indicates that the oil pressure is abnormal, accompanied by three warning sounds. At this time, you must stop and check the oil level. If the level is slightly below the bottom line, you can drive at a slow speed and drive to the nearest maintenance station, such as far away. If it is below the bottom line, you must stop driving. The engine oil that comes with the vehicle can be appropriately added. The brand and grade of the engine oil are required to be the same as the original one; if not, at least the grade of the engine oil is the same, but this is only an emergency treatment, and the owner should also Send the car to the service station. If the oil level is normal and the light is still flashing, you should stop for professional help.
e. Coolant warning light: If the coolant is too high or too low, it will cause the warning light to light up with 3 sounds. At this time, you must stop and check to see if the cooling water leaks. If there is a leak, you cannot continue to drive; but if it is slightly below the warning level, you can add mineral water or tap water, and you can drive at a slower speed as appropriate to the nearest maintenance station; If the liquid level is already below the red line, you must stop for professional help.
3. Yellow warning light
The yellow warning light is on, indicating that the car is malfunctioning, but it is not serious, and reminding the owner to pay attention.
a. Electronic accelerator (EPC) indicator light (equivalent to engine warning light). After the light turns on, the owner first checks the water temperature and oil pressure. In addition, pay attention to whether there is abnormal noise in the engine. If there is, you must stop driving. The reasons for this are more complicated and must be dealt with by professional maintenance personnel. If there are no problems, the owner should drive the car to the repair station at a slow speed for inspection.
b. Engine oil indicator light. The problem of the light performance is the same as when it is red, but the problem is not very serious, remind the owner to pay attention.
c. Brake pad indicator light (brake pad indicator light). After the lights are on, the owner should check the front and rear brake pads for problems. You can continue driving at this time, but you must send it to the repair station as soon as possible.
d. Anti-theft alarm light. Under normal circumstances, the light will automatically go out after being on for three seconds. If it keeps on, it means that an illegal key is being used.
e.airbagIndicator light. Under normal circumstances, the light will automatically go out after being on for three seconds. If it stays on, it indicates that the airbag has failed. However, the owner can rest assured that the airbag will not burst.
f. The door opening status indicator light. When the light is on, the door of the corresponding part is not closed tightly.
4. Precautions for daily driving:
a. Car owners must do routine inspections before driving every day, such as checking engine oil, brake fluid,Water tankCoolant, power steering pump oil level, etc.
b.When the vehicle is turningsteering wheelDon't beat it to death.Because of thisBooster pumpThe pressure will increase several times or even higher, and the continuous killing of the square plate will shorten the life of the booster pump. If this happens accidentally, the owner must release the steering wheel in the shortest possible time to allow it to return freely.
c. The ignition key does not turn on the car, you can turn the key while shaking the steering wheel.
d. For automatic transmission models, remove the key lever and be sure to put it in P gear.
e. Passat’s maintenance cycle is 7,000 kilometers. In order to prevent problems before they happen, owners should read the owner’s manual carefully.
f. Passat must use No. 95 and above (RON) premium unleaded gasoline. The car owner must go to a regular gas station to refuel. Inferior gasoline cannot be completely burned, which may cause the engine to knock and become weak.Three-way catalytic converterPremature damage may cause the engine to flush cylinders in severe cases.
5. How to know the first timetireAir leak
Make a circle in front of the first EMU for inspectiontire.
In the second driving, the vehicle veered off, and it felt different from the original one.
The vehicle flicked slightly in the third direction.
Observe the height of the four corners of the car after the fourth stop.
The fifth gliding is not good, and acceleration is weak.
There were regular noises and vibrations from the tires during the sixth drive.
6. Wintercar maintenance
a. antifreeze:
Most vehicles currently use antifreeze, if your enginecooling systemThere is still water inside, it is recommended that you replace it with antifreeze; if the vehicle is already antifreeze, check the freezing temperature of the antifreeze. Generally, the freezing point of the antifreeze is below -35℃. If it is lower than -20℃, please change it. . The correct service life of the sub-zero antifreeze is 2 years. If it reaches this limit, please replace it to ensure the cooling and antifreeze effect of the engine.
The engine cooling system must be carefully cleaned before adding the antifreeze, because the antifreeze is added with a descaling agent anddetergentIf the engine cooling system is not cleaned before use, the water tank should be soaked in 10% caustic soda aqueous solution for one hour, and then the flushing liquid should be drained, and then rinsed repeatedly with demineralized water 2-3 times to remove the original scale accumulated in the engine cooling system , The antifreeze can be added after flushing.
When changing the antifreeze for your car, be sure to check the factory name, factory address, telephone number, production date, freezing point, boiling point and other items on the package. Regular products are fully labeled and clearly written; fake and inferior products are blurred and easy to erase, and the packaging labels are inconsistent or incomplete. In addition, pay special attention to checking the brand of antifreeze, that is, the freezing point value.
b. Engine oil:
In winter, it should be replaced with the same grade of antifreeze oil. Whether the quality level and viscosity index of the engine oil are selected reasonably will directly affect the start-up and driving performance of the engine in winter, and play an important role in the maintenance of the vehicle.Different brands, but the same kind and viscositylubricating oilGenerally cannot be mixed with each other. Although the types and viscosity of the two oils are exactly the same, the chemical composition of the two oils is not necessarily the same.
In order to reduce fuel consumption and emissions, some of the latest engines usually require the use of low-viscosity oils. For example, 5W-20 or 5W-30 are used in all seasons. For this, please refer to the vehicle maintenance manual. The manual does not clearly require the use of low viscosity all year round. For the engine oil, the oil must be selected according to the environment and the temperature of the season.
c. Battery
Affected by the temperature in winter, the engine is often difficult to start when the car is cold, and it needs to be beaten several times.motorTo get into the car. At this time, the battery needs to work in good condition, otherwise it will be difficult to start the engine due to excessive consumption of battery power. Winter is the vulnerable period of the battery. Pay special attention to the rain and snow in early winter not to flow into the battery to prevent the battery from being damaged. Check the drain hole under the Passat battery during the rainy season. After a long period of time, the silt will cause the water to pour back into the car after the rain.
7.Cleaning of Passat window trim
The surface of the Passat window trim (inside the glass) is black flocking. Because the surface is not smooth, it is easy to adhere to fiber-like dust, which is very embarrassing and very difficult to clean. This phenomenon is more serious in the dry weather in the north. To clean it, such as wiping with a cloth, the fibers on the cloth will adhere to it more, making it more ugly; using a brush will not solve the problem at all.
A simple and effective cleaning method is to use tape (the kind that seals the box). Place the adhesive surface of the tape against the suede surface of the decorative strip, gently press the tape and then tear off the tape. The fiber-like dust on the decorative strip can adhere to the tape and be removed. If the effect is not satisfactory, you can stick it again, and a clean and black window trim will be displayed in front of you.
For new cars, good running-in (run-in) helps to extend the service life of the vehicle. The initial running-in mileage of Passat is 1500 kilometers (it can be shortened to 1000 kilometers with experience).
