Is an appointment required for the first car maintenance?

The first car maintenance does not require an appointment; you can go directly to the 4S store.

Prolonged use can form a thick layer of carbon deposits on the engine surface, which can cause significant corrosion to the rubber components in the engine. Preventing evaporation of gasoline and water: In summer, the temperature is generally higher. Therefore, gasoline and water evaporate more easily than usual. It is necessary to frequently check the water tank and fuel tank, and promptly add more when gasoline and water levels are low. Maintaining hygiene inside the car: Summer is the season when bacteria multiply the fastest, so the interior of the car should be kept clean, especially items that are prone to getting dirty such as car seat covers, steering wheel covers, and car floor mats.
