汽车保养是指定期对汽车相关部分进行检查、清洁、补给、润滑、调整或更换某些零件的预防性工作，又称汽车维护。保养的目的是保持车容整洁，技术状况正常，消除隐患，预防故障发生，减缓劣化过程，延长使用周期。
Vehicle maintenance is the preventive work of inspecting, cleaning, supplying, lubricating, adjusting or replacing some parts of the vehicle in a specified period, also known as vehicle maintenance. the purpose of maintenance is to keep the vehicle clean and tidy,the technical condition is normal,eliminate hidden dangers,prevent faults,slow down the deterioration process and prolong the service life
一、车辆使用前、中、后，要及时地清除车体上的灰尘，尽量减少车身静电对灰尘的吸附；
1、 Before, during and after the use of the vehicle, the dust on the vehicle body shall be removed in time to minimize the adsorption of static electricity on the vehicle body;
二、擦洗车辆要用干净、柔软的擦布或海绵，防止混入金属屑和沙粒，勿用干布、干毛巾、干海绵擦车，以免留下划痕。擦拭时，应顺着水流的方向自上而下轻轻地擦拭，不应画圈和横向擦拭。
2、 Clean and soft wiping cloth or sponge shall be used to wipe the vehicle to prevent metal chips and sand from mixing. Do not wipe the vehicle with dry cloth, dry towel and dry sponge to avoid scratches. When wiping, wipe gently from top to bottom along the direction of water flow, and do not draw circles and wipe horizontally.
三、对一些特殊的腐蚀性极强的痕迹（如沥青、鸟粪、昆虫等），要及时清除。大朗奔驰保养专家认为对此，必须用专用清洁剂清洗，不要随意使用刀片刮削或用汽油消除，以免伤害漆面。
3、 Some special highly corrosive traces (such as asphalt, bird droppings, insects, etc.) shall be removed in time. Dalang Benz maintenance experts believe that this must be cleaned with special detergent. Do not scrape with a blade or eliminate it with gasoline at will, so as not to damage the paint.
四、雨后及时冲洗。雨后车身上的雨渍会逐渐缩小，使雨水酸性物质的浓度逐渐增大，如果不尽快用清水冲洗雨渍久而久之就会损害面漆。
4、 Wash in time after rain. After the rain, the rain stains on the car body will gradually shrink, making the concentration of rainwater acidic substances gradually increase. If the rain stains are not washed with clean water as soon as possible, the finish paint will be damaged over time.
五、洗车时，应待发动机冷却后进行，不要在烈日或高温下清洗车辆，以免洗洁剂被烘干而留下痕迹。平常自己动手冲洗车辆要用专用洗涤剂和中性活水，不应使用碱性大的洗衣粉、肥皂水和洗涤灵，以防洗掉漆面中的油脂，加速漆面老化。
5、 When washing the car, it should be carried out after the engine is cooled. Do not wash the vehicle in the hot sun or high temperature, so as not to leave traces after the detergent is dried. Usually, special detergent and neutral running water shall be used to wash the vehicle by yourself. Alkaline washing powder, soapy water and detergent shall not be used to prevent the grease in the paint from being washed off and accelerate the aging of the paint.
