The car maintenance tips are as follows: 1. Spare engine oil: If the car experiences poor acceleration, blue smoke from the exhaust, and the engine oil warning light on the dashboard comes on, it may indicate oil burning. In this case, you can stop the car, open the hood, and check the oil level with the dipstick. If the oil level has decreased, this confirms the issue. If you have spare oil, you can add it and then proceed to the nearest repair shop. If not, it is advisable to call for emergency repair and avoid driving further, as this can cause significant damage to the engine. 2. Jack and portable tire pressure gauge: If you accidentally run over a nail and the tire becomes unusable, first use the tire pressure gauge to measure the pressure. If the pressure hasn't changed much, you can continue driving. If there is a significant drop in pressure, use the jack from the trunk to replace the spare tire. When using the jack, make sure to place it on the lower side rail, which is the sturdy metal body of the car beneath the door between the two tires. Be very careful with this, as improper placement can cause the car to deform under its weight or even slip suddenly during the tire change, leading to irreversible accidents. 3. Dual-purpose wrench and screwdriver: These are tools with two usable ends, making them very versatile. Most screws on headlights and batteries can be loosened with this wrench. The dual-purpose screwdriver has one flat end and one Phillips end, suitable for common screws. 4. Jumper cables: If your car battery dies, you can stop another car for help and use jumper cables to connect the batteries of both cars to start your vehicle immediately. 5. Always carry pure water: Pure water is not just for drinking. If the windshield washer runs out of water or the radiator leaks, you can use it as an emergency solution. When you reach a repair shop, replace the water in the radiator with specialized antifreeze or coolant. 6. Tow rope: A tow rope has many uses and doesn't take up much space in the car. In case of an accident where the car cannot be moved out of danger, having a tow rope allows you to seek help from another vehicle to tow your car to safety if a tow truck is not immediately available.
