In winter driving, attention should be paid to the external circulation of the air conditioner and then closed to prevent frost formation

Cold winds are bleak and winter is approaching. In the ice and snow, our engines are still burning with passion and vitality. Here are some tips for winter driving and vehicle maintenance.

First, winter starts difficult

Many riders reflect that driving in the morning can be difficult in the morning.

Explanation: The vehicle is started in winter because the temperature at night is very low, and the low temperature will slow down the engine oil flow. Therefore, there is a requirement for the minimum starting temperature of the oil, so it is recommended that everyone use the quality guaranteed oil recommended by the 4S shop. Using the oil of the approved brand model can ensure that our car always maintains a stable working condition while being more effective. Extend the service life of vehicle components.

Recommendation: We recommend the owner to use the engine oil recommended by the 4S shop. At the same time, we recommend that the owner turn the key to the vehicle start preparation state before starting. The owner can press the start button directly without pressing the brake. The purpose is to allow the vehicle to finish the self-test before starting. Starting the vehicle after self-test can better protect the circuit of the vehicle and minimize the load when the vehicle is started. Then turn off the radio, interior lighting and air conditioning, and then start the vehicle. The owner of the manual transmission can also start the clutch and start it. If it is persisted for a long time, the working life of the air motor can be extended. It is very good for our car.

Second, winter glass frost

A lot of riders report: When they get into the car in the morning in winter, there will be a lot of frost on the windows, which will affect the sight very much.

Explanation: When we parked, the inside of the car will maintain a comfortable temperature because of the air conditioning. At night, the temperature outside the car is very cold. Therefore, when the cold air contacts the glass of the car with temperature, it will produce condensation water. It forms frost at low temperatures.

Suggestion: We recommend that when shutting down the air conditioner during parking, adjust the air duct of the air conditioner into an external circulation state and shut it down. You can even run the air conditioner in the external circulation + low temperature setting state for a period of time to allow the temperature inside the vehicle. It will not drop to the extent that the window condensing water is produced, but it is not recommended to open the window to a gap, because in the public parking environment, the gap in the window may cause the loss of property in our car, and at the very least, it will blur our car. Interior.

If you already have frost, do not use hot water to flush the glass. Even if you use a product with a very good quality and high temperature range, under the impact of sudden cold and sudden heat, the glass of the car may also be burst. In addition, besides not using hot water, we should not immediately use a wiper to scrape. Because the condensate flows down the windshield before it is frosted, the possibility that the windshield is frosted is very high. Forcibly starting the windshield wiper may not only cause damage to the windshield wiper, but also cause damage. The wiper motor may be burned due to the wiper sticking to the windshield. The glass water may also burn the glass water pump if the temperature is relatively low.

The correct approach is: After we can start the vehicle, after the engine temperature rises, use the option of blown glass in the air-conditioning option to increase the temperature on the glass. In addition, you can buy some special low-temperature glass water in the 4S shop. The low-temperature environment glass water not only provides you with a clear and bright driving experience, but also protects your vehicle cleaning system in normal operation in a low-temperature environment.

Third, about the hot car in winter

Many riders reflect: Should winter be idle for a period of time after it starts, and should it be better to wait until the water temperature rises?

Explanation: Because the temperature in winter is relatively cold, the oil in the engine and transmission mechanism can no longer meet the standard flow rate and working conditions for the first time. Therefore, it is no problem to give the engine a warm-up time, but if it keeps At very low idle speeds, the pressure of the oil pump cannot push the oil to the top of the engine. Therefore, overheated hot wheels may cause unnecessary wear of the overhead camshaft, and it is easier to generate carbon deposits in the engine block. .

Suggestion: We recommend that the rider can start the car at a relatively slow speed after launching the car. As long as the speed does not exceed 2,000 rpm and the vehicle is not accelerated, the oil film on the engine parts will protect the engine from excessive wear and tear. During the low-speed driving process, the lubricant in the operating mechanism can be attached to the operating mechanism more quickly and better, enabling our car to enter the working state more quickly.

Fourth, the beginning of winter driving safety
Many riders reflect that after driving in the snow, it will slip, and it will be dangerous to start swinging.

Note: Because the torque of some rear-drive cars is very large, slippage may occur when the frictional force on ice and snow roads is relatively small, and the cause of flicking is usually due to the rear-wheel drive if the road is not inclined. The position of the front wheel was not placed.

Suggestions: First, we must maintain the forward direction of the front-wheel integrity. Do not swing our steering wheel because of slippage. In the slippery state, twisting the steering wheel will surely cause a tailtail. Therefore, we suggest that you put your hands on the 3 o'clock and 9 o'clock directions of the steering wheel. The reason is that as long as our hands are flat, our wheel's angular position must be upright and not misaligned. Second, we use auto-shift riders to switch to tiptronic mode after hanging the D-speed “forward range” and choose to start with 2nd or even 3rd gear. This will reduce the torque that the rear wheels will instantly convey to the ground. To achieve a normal start. If it is a manual shift owner, we can directly hang on the 2nd or 3rd gear after activating the DTC function by gently lifting the clutch and stepping on the accelerator to start. It can also achieve a better start effect.

Fifth, the brakes of winter driving safety

Many riders reflect that in winter, it is easy to hold the brakes on the brakes. Although there is anti-lock braking assistance, it is still very dangerous to slide laterally on the brakes when going downhill.

Note: Although there is ABS anti-lock support, but many owners in the ABS start when the pedal rebound, it will be very nervous, and the brakes did not dare to step in the end, so the braking distance is very long, it is easy to start in the ABS system A short moment of time before work is locked and causes the car to slip.

Suggestions: First of all, we suggest that we should make the same direction as possible at the start to ensure that the direction of the front wheels is consistent with the direction of the inertia of the vehicle. That is, put your hands on the 3 o'clock and 9 o'clock directions of the steering wheel, put your hands flat, and let the wheels be placed. positive. Afterwards, we suggest that our riders vigorously step on the brakes in case of an emergency. As long as the steering wheel is pointed, the car will not significantly slip, and the ABS system will control the brake pedal during operation. The driver will not feel the obvious rebound force when the ABS starts working. Therefore, the driver can step on the brakes to control the braking distance in a straight line.

In addition, when an emergency brake is needed in rain and snow, our braking distance will increase because of the rain or snow water on the brake disc. For our car owners, the speed of the car will be the first time. Control is very important.

Six, winter maintenance points

In addition, winter maintenance is also very important. In addition to the above-mentioned engine oil and glass water, low-temperature antifreeze can remain unfrozen when the engine is shut down and the ambient temperature is very low. Therefore, the outdoor temperature is not too high. The low temperature causes freezing of the tank, which can provide better cycle cooling support for the engine's operation in a shorter period of time after the vehicle is started.

Winter tires provide more car protection for the majority of riders. Winter tires feature extremely cold-resistant silicide, special ribbed design and self-cleaning treads, even if the road surface temperature is below 7°C. When your car is driving at a speed of 30 kilometers per hour on a frozen road for emergency braking, the winter tyres will shorten the braking distance by 11 meters more than ordinary summer tyres. Maximize the safety of drivers and vehicles.
