The weather has been gradually cold, winter car care will undoubtedly become the car owners are most concerned about the topic.Although the cold weather will cause some of the car's bad condition, but we do not have to worry too much, as long as the regular regular maintenance and inspection, the car does not Because of the cold and broken.And often cause vehicle failure is some bad driving habits and do not understand the use of vehicles, and today we first look at the car cold start precautions and the use of air conditioning.
Start the car in winter
In fact, when starting the vehicle can be noted: When we start the vehicle can usually be found, the tachometer pointer will be momentarily at a higher position than normal idle speed (automatic transmission more obvious.) This is the ignition when the car Computer auto control module (commonly known as ECU) in the car to make the fuel injection system to inject some more fuel into the cylinder, to enhance the engine speed, so that the rapid warming in the cold state.After the start of the vehicle, when idle speed lube No supply in place, so the most prone to wear and tear.
The correct approach: about 30 seconds after the start of waiting for the speed down to normal driving on the road until the water temperature gauge to reach the middle of the normal position.
Winter vehicles start up hard
Parked cars for a long time can not be started, especially the use of longer life of the car, winter often encounter difficulties in starting the car is generally difficult to start due to battery power shortage, so long time to turn off the CD, blower and lighting Lights, etc., to prevent electricity consumption.
Cold weather, it is timely to the 4S shop or repair shop for vehicle battery maintenance inspection, if the measured voltage value is greater than 12V, indicating that the battery is normal .If the voltage is less than 12V, indicating that the battery is already in low battery condition .If the low At 10.5V, it means not far from the scrap, it is best to be replaced as soon as possible.
Air conditioning problems and methods of use
First, open the winter warm wind need to open the A / C button (start / turn off the air conditioning compressor)?
Here you need to know In fact, the principle of warm and cold are not the same, the warm air is formed by the engine cooling, the engine compartment has a small fan, the cooling system to collect the heat blown inside the car.If you do not open the warm air, These heat will also be discharged to the car.
So the summer air conditioners, be sure to first open the A / C button that warm it In fact, the warm air just use the car's internal heat cycle, there is no need to start the compressor, so you want to turn on the warm air, Increase the temperature and then adjust the air volume can be.
No air conditioning in the case, why the outlet is still a hot air?
In the closed state of the air conditioner, in order to ensure the air circulation in the cab, the air-conditioner system should be switched to the external circulation mode at this time, when the oncoming vehicle absorbs the heat from the radiator and the exhaust system, it will be distributed from the air conditioner Box into the car, it will feel the outlet in the air conditioning is still off when the hot air, which is normal.
Correct practices: Automatic air-conditioned models to temperature set to LO (lowest) position, and select the inner loop mode, which can effectively eliminate this phenomenon. Manual air-conditioning rotation temperature button to adjust the temperature, and select the inner loop mode.
In addition to winter car air conditioning tips
The wipers are frozen
The weather turns cold, even though it is not yet snowy, but in the early morning it is often found that the window will condense with a layer of water mist that will freeze the wipers and glass at night when temperatures are below 0 ° C in the morning.
At this point need to be careful not to be forced to turn on the wipers, wipers will accelerate the wear and tear cracks, serious wipers will damage the motor.
Solution: If the wiper blade is frozen on the windshield, do not rinse directly with hot water, but turn on the air conditioner until the hot air blows and the blow mode is set as the front windshield to naturally freeze the wiper blade. Also do not forget wiper spray bottle to be frosted glass water.
2. Window fog
Winter, because of the large temperature difference between inside and outside the cab, the weather encountered a large air humidity, so often there will be fog attached to the glass, seriously affecting the line of sight.
Solution:
Method one: the vehicle windows fogging, you can open the windows or skylight on both sides of the vehicle, so that the air inside the car can convection, the moisture blown away, the fog quickly dissipated.
Method two: open the air conditioner and transferred to the cooling mode, when the cold air blown onto the glass soon fog will be scattered and exhausted, the effect is very direct.
Note: In fact, hot air can also be used to achieve the effect of defogging, but also to solve the problem of repeated fogging will not be like a cold air and then appear again fog, but one thing to remind everyone that if the glass has been fogging on the road, Just open the hot air but will make the fog on the glass more and more.So it is recommended that you do not try to travel with hot air to windshield glass.
Summary: Today we have summarized the use of the car in the winter cold start and air conditioning, I hope we can help, of course, on the winter car tips and precautions is far more than that, we will continue in the recent update We introduced winter car skills to help you correctly and safely through the winter.
