What are the small snowflakes and temperatures displayed on the dashboard of Volkswagen Tiguan?

First, the display of small snowflakes and temperature on the dashboard of Volkswagen Tiguan means:

When the ambient temperature drops below 4 degrees, the road surface is in danger of freezing. Small snowflakes and temperature display remind drivers that the road may be frozen and they need to drive carefully.

Second, what should I pay attention to when driving in low temperature weather:

1. Check the whole vehicle before driving.

In the cold winter, the engine needs more protection. Check not only the label of engine lubricating oil for it, but also the antifreeze in the water tank. If four seasons antifreeze is used, it can be replaced once every two years or so, but the freezing point should be checked.

Even fewer people pay attention to oil. Generally speaking, the internationally recognized classification standard is SAE classification of American Society of Automotive Engineers, which clearly indicates the use environment of engine oil. W on the oil drum package stands for winter. The smaller the numbers such as 0W, 5W, 10W, the better the low-temperature startability. For example, 0WW stands for maintaining good lubricity and fluidity at MINUS 30 degrees.

In addition to low-temperature viscosity grades, there are also high-temperature viscosity grades SAE20, 30, 40, 50 and so on. The larger the number, the better the high-temperature lubrication effect of oil and the more stable the viscosity.

2, get off at low temperature to start like this.

In the low temperature state, many vehicles will encounter the problem of ignition difficulty when starting, or sometimes suddenly turn off when driving. The correct answer is: it is best to control the time of starting the vehicle within 5 seconds each time, that is, turning the key or pressing the start switch should not last too long. If the startup is unsuccessful for three times, it should be stopped for a few minutes before starting, so as not to damage the battery.

In extremely cold weather, you can remove the battery and keep it warm indoors, and then start it in the morning and install it again. Although this is a bit troublesome, it can ensure the smooth start of the vehicle.

Due to the cold temperature in winter, lubricating oil will not flow easily due to the increase of viscosity. After starting the engine, start the engine slowly to warm up. During this period, don't slam on the accelerator and don't let the engine rotate too fast.

In addition, the preheating time does not need to be too long, as long as the thermometer pointer starts to rise.

3. Pay special attention to speed control when driving on the road.

The thin ice on the road surface reduces the friction coefficient between the tire and the road surface, greatly reduces the adhesion, and is easy to slip or idle. When driving a manual transmission vehicle, the start must be soft and slow, so as to "slowly lift the clutch and lightly step on the oil". On the one hand, this is to make the load of the engine as small as possible when it does not reach the normal working temperature, and on the other hand, it is also beneficial to the safety of the engine, tires and driving. The starting mode of lightly stepping on the accelerator is equally effective for driving automatic vehicles.

In gear selection, drivers should change gears frequently in winter, just like driving a vehicle during the running-in period. We must pay attention to the selection of suitable gears and do a good job of coordination between oil and gas. Too low and too high gears are easy to make the car out of control, which is especially important when driving on ice and snow roads. When driving, appropriately increase the distance between the front and rear cars to prevent the front car from suddenly braking, and at the same time pay attention to the distance from the left and right cars.
