The transmission fluid for the Changan CS55 should be changed every 30,000 kilometers. When changing the transmission fluid, you can see two screws underneath the transmission. One can be loosened with an 8mm hex key - this is the drain port. After draining, it should be screwed back in before refilling. The other screw requires a 17mm hex key to loosen - this is the fill port. Once removed, there is an opening where a bent tube can be inserted. Generally, 4 to 6 liters of transmission fluid is sufficient. The Changan CS55 is an SUV model under the Changan brand, with dimensions of 4500mm in length, 1855mm in width, and 1690mm in height, and a wheelbase of 2650mm. For the interior, the Changan CS55 follows a refined design approach, featuring a three-spoke steering wheel and a symmetrical center console. The air vents, center control area, and red trim strips on both sides of the dashboard add distinctive character.

I've been driving for many years and have owned a Changan CS55 for nearly three years. Transmission fluid maintenance is quite crucial; it's generally recommended to change it every 40,000 to 60,000 kilometers, but it's best to refer to the official manual for specific intervals. Driving habits have a significant impact—if I frequently drive on highways or in congested city traffic, the fluid tends to degrade faster. Not changing it can lead to transmission wear and increased fuel consumption, while regular changes can extend the vehicle's lifespan. I also check the fluid level myself every six months, using the dipstick to observe its color and height; if the fluid appears black or dark, it's time for a change. Additionally, driving in cold regions causes faster temperature fluctuations in the fluid, so changing it earlier is safer. Overall, sticking to fluid changes is a small investment that can prevent major repairs.

How long can hazard lights last when the engine is off?

Hazard lights can last for a full day and night when the engine is off. The hazard warning flasher, commonly known as the hazard lights or emergency flashers, is a functional lighting system used to alert other vehicles in case of emergencies. It is also necessary to turn on the hazard lights when parking on the roadside to prevent rear-end collisions. Situations requiring the use of hazard lights include: 1. Driving in foggy conditions—due to poor visibility, both hazard lights and fog lights should be activated; 2. In case of vehicle breakdown or traffic accidents on the road, hazard lights should be turned on to alert passing vehicles for safety; 3. When towing a malfunctioning vehicle, both the towing vehicle and the towed vehicle should activate hazard lights to indicate their non-normal status; 4. When temporarily parked on the road, hazard lights should be used to warn other vehicles; 5. When forming a convoy permitted by traffic authorities, all vehicles in the convoy should turn on their hazard lights.

Where is the ETC installed on the car?

For small vehicles, the ETC device is installed in the upper middle part of the front windshield, while for large vehicles, it is installed in the lower middle part. The ETC does not require charging or battery replacement as it has a solar panel on the back that can charge itself. When installing, avoid the black areas on the windshield and positions that may block the solar panel. Correct installation positions for ETC: 1. The height should be no less than 1.2 meters and no more than 2.5 meters; 2. The installation angle N should be between 30 and 90 degrees; 3. For vehicles with factory-installed or aftermarket anti-explosion film, the metal ions in the film may affect the signal transmission of the microwave communication link. Installation should be done in the microwave skylight area or by cutting an 8cm by 10cm rectangular area in the anti-explosion film.

Should Defogging Use Internal or External Air Circulation?

Defogging should use external air circulation. When fog is detected on the windshield, first adjust the air vents to the front windshield, turn on the air conditioning cooling function along with external circulation, and use the maximum fan speed. It typically takes only about ten seconds to quickly blow away the fog on the glass. If driving on long-distance or highway sections where opening windows for ventilation is inconvenient, external circulation should be activated. If driving on congested urban roads, internal circulation should be used. If driving on congested urban roads, internal circulation should be used. All car air conditioning systems are equipped with air filters, which need to be replaced periodically. Generally, car air filters should be replaced every 10,000 kilometers.

Can the new Sylphy use 0W40 engine oil?

The new Sylphy can use 0W40 engine oil. More details are as follows: Reasons why Japanese cars mostly use low-viscosity engine oil: Japanese cars mostly use low-viscosity engine oil due to various reasons, such as the development philosophy of Japanese cars (fuel efficiency), and the high precision of Japanese car engines, which have less dependence on the viscosity of engine oil. Recommendations for using 0W40: If the car is relatively old and has oil burning issues, 40-viscosity engine oil can be used. 0W-40 is the SAE of the engine oil, indicating the viscosity value of the oil. The smaller the number before W, the better the low-temperature fluidity of the oil, representing a lower usable ambient temperature and better protection for the engine during cold starts. The number after W represents the kinematic viscosity of the oil at 100°C. The higher the number, the higher the viscosity, the better the protection performance at high temperatures, and the better the stability at high temperatures. The higher the oil viscosity, the greater the resistance of the engine operation, and the higher the fuel consumption of the car.

How Often Should Brake Fluid Be Replaced in a Sedan?

It is recommended to replace the brake fluid in a sedan every 2 years. Brake fluid has certain corrosive properties and strong water absorption. Nowadays, repair shops have specialized tools to test the water content in brake fluid, so you can perform a test to determine if replacement is necessary. Brake fluid must be replaced regularly when it reaches the maintenance interval, and it is advisable to follow the manufacturer's recommended maintenance schedule. Generally, brake fluid should be replaced every two years, as prolonged use can cause wear to the rubber cups and pistons in the brake pump, leading to contamination of the brake fluid, which is why replacement is recommended. Brake fluid is crucial, and when selecting it, be cautious—using substandard or low-quality brake fluid can corrode the rubber seals in the brake pump and negatively impact braking performance. Therefore, if the brake fluid is low, it is best to purchase the original vehicle's brake fluid from an authorized repair shop.
