2. Always check the tire pressure, neither too high nor too low. Regularly clean the sand and pebbles on the tires. Regular tire transposition, such as every 1.5 thousand kilometers or according to the wear condition, can prolong the service life of the tire, because the front wheel is responsible for steering and the engine is heavy, and the front wheel generally wears faster. In addition, if it is found that the steering wheel jitter is aggravated at high speed, it is necessary to do four-wheel dynamic balance, which can reduce the wear and tear of the mechanical structure. Or if conditions permit, you can take the initiative to do a four-wheel dynamic balance every 20,000 or 25,000 kilometers. Generally, Citroen's car is not easy to deviate, so it needs four-wheel alignment. If the situation is not serious, the tire pressure problem can be ruled out, and four-wheel alignment should not be done easily.
Don't kill the steering wheel for a long time when turning or entering the parking space. Killing the steering wheel for a long time will cause great damage to the power steering pump. You'd better turn the steering wheel to the right before turning off the engine. If you don't park in a steep place, don't pull the handbrake too tightly. It is not impossible. It is best not to park your car on a steep slope for a long time, or park your car in a place where the body tilts left and right, such as when two wheels are on the side of the road, two tires are on the road, and the body tilts left and right.
At present, the engines are running at high speed. In order to reduce carbon deposition and prolong engine life, the speed should be as high as possible when shifting gears. Never follow the old textbooks or listen to the old saying that the old driver shifts gears at 2000. It is best to shift gears at least 3000. In this way, although stepping on the accelerator slightly improves the speed and wastes a little engine oil, it reduces the number of times of cleaning up carbon deposits, saves money and protects the life of the engine. In addition, if you are skilled, you can quickly increase the high-speed speed and shift gears quickly, but it is easier to enter the economic speed and fuel-saving state, and it does not cost much oil. Especially the Sega 2.0 engine, which has excellent performance, should not be buried by carbon deposition or other bad driving habits.
5. When driving, keep your eyes open and listen to all directions, learn to slow down and downshift in advance, and reduce sudden braking. For example, if you see a red light in the distance or the road ahead is congested, you should slow down at the intersection instead of slamming on the brakes. This is not only safe and fuel-efficient, but also saves brake pads. Replacing the brake pads of four wheels is not cheap.
6. Check the liquid level in time, such as engine oil, power steering oil, brake fluid, cooling fluid and glass cleaning fluid. The filling position, inspection position and instructions of these liquid levels are all there, or you don't understand. When you go to 4S for maintenance, you can ask the repairman. In particular, Citroen's car oil change cycle is relatively long, and the specification is 15000 km. However, considering the domestic oil products, short distance and poor vehicle heat, the oil change cycle can be shortened to 8000- 10000 km, so it is best to check the liquid level regularly every 1000- 1500 km. If you often run on dirty roads, take out the air filter regularly to blow dust. This is very simple, four screws will do, but it is better for the engine. In addition, regarding the replacement of brake fluid, Citroen's instructions say that it is changed once every two years. Unless otherwise specified in the manual, ordinary cars are usually replaced once every two years (my cousin's Honda Civic doesn't know why it needs to be replaced once every three years, but it may be in good sealing condition). Changing brake fluid is for your own safety. Don't be greedy for cheap, go to a small shop to change inferior brake fluid, and don't extend the oil change time to save money. Under special circumstances, the longest period shall not exceed two and a half years. Because the brake fluid itself has the characteristics of water absorption, it is required to be replaced in time within the specified time. In addition, if it is useless after replacement, the remaining unsealed brake fluid cannot be stored for two years because of water absorption. But if you have changed the brake pads recently, you can leave them for a while, and if your friend's car is changed at the same time, you can also give them to him. If the owner's area is located in the high temperature area in the south, and the freezing time is short in winter, glass cleaning liquid can be replaced by water for most of the year, but one kind of water has no decontamination ability, and the other kind will freeze and crack containers and pipes if it is forgotten to replace them before it is cold. Although the problem of coolant can be replaced by water in hot weather or emergency, it is best to use coolant that meets the standard. One is that if the water tank is frozen and cracked, the other professional coolant has a good cooling effect and is not easy to produce scale to corrode the water tank. This coolant is also changed every two years according to the requirements of Citroen, but if it is not particularly cold in winter, the replacement cycle can be relaxed.
