BMW special repair will explain to you that the following maintenance is required for BMW maintenance:
一、 宝马汽车发动机油量检查将车辆停放在水平的路面上。拔出游标尺检查机油量，油亮若在(F)和(L)两个标线之内，则属于正常范围，若低于(L)位。则应添加指定型号的机油，机油后的液面不能高于(F)位。
1、 Check the fuel level of BMW engine and park the vehicle on a level road. Pull out the travel scale to check the oil quantity. If the oil brightness is within the two marking lines (f) and (L), it belongs to the normal range. If it is lower than the (L) position. The specified model of engine oil shall be added, and the liquid level behind the engine oil shall not be higher than (f).
二、 宝马汽车制动液面的检查制动在高、低位之间则表示正常。如果制动液接近下限或低于下限则表示系统中可能有泄漏或制动蹄片磨损过多，应及时到维修站进行检修。
2、 Check the brake fluid level of BMW. If the brake is between high and low, it means it is normal. If the brake fluid is close to or lower than the lower limit, it indicates that there may be leakage in the system or excessive wear of brake shoes, and it shall be repaired at the maintenance station in time.
补加制动液时，要注意加同一种型号的制动液，防止损坏皮碗，注意保护好油漆防止腐蚀漆面。
When adding brake fluid, pay attention to adding brake fluid of the same model to prevent damage to the leather cup, and pay attention to protect the paint to prevent corrosion of the paint surface.
三、 宝马汽车蓄电池的保养检查检查蓄电池固定是否牢固，电解液应在上限和下限之间，接近下线时应及时补加电解液或蒸馏水至高位线。保持蓄电池正负电缆接触良好，并保持蓄电池清洁干燥。放置时间较长的车辆要摘下蓄电池的正负极电缆，相隔半个月左右重新接线起动发动机约20分钟后，如果电量明显不足要及时充电。
3、 Maintenance and inspection of BMW battery. Check whether the battery is firmly fixed. The electrolyte should be between the upper limit and the lower limit. When approaching the offline, add electrolyte or distilled water to the high level line in time. Keep the positive and negative cables of the battery in good contact, and keep the battery clean and dry. For vehicles that have been stored for a long time, remove the positive and negative cables of the battery, rewire them every half a month or so, and charge them in time if the power is obviously insufficient after starting the engine for about 20 minutes.
四、宝马汽车皮带的检查起动发动机或平时驾驶车辆时，皮带发响，一种情况是皮带长期没有检查调整造成，按正常标准调整即可。另一种情况是皮带老化，需更换。
4、 Inspection of BMW's belt when starting the engine or driving the vehicle at ordinary times, the belt makes a noise. One case is that the belt has not been inspected and adjusted for a long time, and it can be adjusted according to the normal standard. The other is that the belt is aging and needs to be replaced.
五、 宝马汽车火花塞的检查正常的火花塞绝缘陶瓷完好。没有破裂漏电现象，火花塞间隙0.8+-0.0mm放电时，火花呈蓝色，较强。若发现异常需进行调整间隙或更换火花塞。
5、 The inspection of BMW spark plug is normal, and the insulation ceramics of spark plug are intact. There is no rupture and leakage. When the spark plug gap is 0.8 + - 0.0mm, the spark is blue and strong. If any abnormality is found, adjust the gap or replace the spark plug.
