Spring Festival self-driving tour: cold and warmth safety first

In order to ensure safe driving in winter, in addition to driving carefully, owners should pay attention to the following points in the use of tires:

1. Tire pressure. It is very important to maintain the standard air pressure of winter tires, and increase or decrease the air pressure according to the conditions of the road under appropriate conditions. Due to the large temperature difference in winter, the temperature of the air in the tires expands and contracts more, and the air pressure is easier to change. Therefore, car owners should properly increase tire pressure to reduce tire wear and tear. But at the same time, if the road is icy and slipping, high tire pressure will affect the adhesion of the tire. Therefore, in order to increase the adhesion of the tires, winter owners can appropriately reduce the tire pressure.

2. Specifications match. Generally speaking, the specifications of winter tires and summer tires or all-weather tires are preferably the same, so that the car can maintain normal driving performance.

3. The installation process. During the installation process, one or two winter tires cannot be installed, and all four tires must be replaced. Because partial replacement will cause uneven adhesion to the ground during use, resulting in danger.

4. Service life. All tires will age with time. For winter tires, the service life is 4-6 winters. Although the tire pattern is still present at this time, due to the aging of rubber, the tread hardness increases, resulting in a decrease in adhesion. At the same time, the depth of the pattern must be above 4 mm to ensure safety. Therefore, the tire should be replaced in time according to the wear.

5. Replace winter tires in time after winter. Since the formula of the tread material for winter tires is specially made for muddy or icy roads in low temperature weather, it has a narrow range of adaptation to temperature and cannot be used as all-weather tires.

Lubricating oil, good fluidity

Just like the blood in the human body, if it is too thick, the fluidity is poor. Insufficient blood supply and oxygen supply to various organs will seriously affect physiological functions. In the cold winter, to ensure that your engine runs smoothly, you must choose a lubricating oil that can flow well at low temperatures.

Mobil professionals reminded that the selection of lubricants, ambient temperature conditions are selection criteria that must be carefully considered. The vast majority of regions in China have four distinct seasons and large temperature differences, and car owners should choose multi-grade lubricant products. Mobil currently has several multi-grade lubricating oils that are suitable for various temperature conditions, especially for vehicles that are often driven by self-driving people all over the country, such as: Mobil Speedmaster 1000, 5W-30, 10W-30, 15W-50 And many other models, can be applied to the external temperature conditions of -30 ℃ to 50 ℃.

Bodywork, full inspection

1. Before departure, it is best to go to the repair shop to do a full body inspection. Now many dealers 4S stores will launch winter free testing activities, as long as you say "I want to drive out for travel" to the maintenance receptionist, they will know how to help you an examination.

2. It is critical to check whether the fuel is full, especially on the highway, especially at night. Do not advocate bringing your own gasoline.

3. Check whether you have a spare car key in case the door cannot be opened.

4. Check whether the lights, signals, horns, rearview mirrors, door locks, glass lifter handles are all available and effective.

5. Check whether the glass water is sufficient, whether the water jet pump is working normally, and whether the elasticity of the wiper blade is normal.

Personally, after finishing the equipment and checking the vehicle, you should check yourself.

1. Please check your vehicle ID and personal ID before departure. You also need to bring the telephone numbers of the contact person of the repair shop and insurance company, in case of any situation, you can call in time.

2. Be optimistic about driving directions, or bring a GPS (car navigation system) with you.

3. When organizing equipment, separate the drinking water, food, odds and ends and other equipment used on the road for easy access. Valuable items such as cameras and mobile phones are best provided with sealable plastic bags and moisture-proof bags just in case.

4. Handbags, luggage and other luggage and valuables should not be placed outside the car in an observable place when leaving the car, so as not to attract thieves.

5. Pay attention to driving safely. Pay attention to master the driving speed, keep a certain distance from the car in front, stop or slow down must be on the right, pay attention to observe the surrounding road dynamics, not to be forgotten.
