What does the small wrench symbol on the car dashboard mean?
1 Answers
The appearance of a small wrench symbol on the car dashboard indicates that the vehicle requires maintenance. Here are the maintenance methods for household cars: 1. Regularly check tire pressure and promptly inspect for foreign objects in tire treads: Excessive tire pressure affects comfort and increases the risk of blowouts. Insufficient tire pressure raises fuel consumption and accelerates tire wear. Normal tire pressure should follow the vehicle's specifications, which can be measured using a tire pressure gauge. In cold winters, ensure tires are slightly more inflated than in summer due to thermal expansion and contraction. Promptly remove small stones, nails, or other debris from tire treads to prevent damage when flung out. Also, carefully inspect tire sidewalls for scratches—if significant marks are found, consult a professional at a tire shop. 2. Timely replacement or addition of antifreeze: Especially in winter when outdoor temperatures are extremely low, sufficient antifreeze is essential for normal vehicle operation. Otherwise, the radiator may freeze, disrupting circulation and causing malfunctions. Antifreeze levels should remain between MAX and MIX marks; replenish if low. Purchase antifreeze from reputable auto parts stores to avoid substandard products that may harm the vehicle and fail to provide proper antifreeze protection. 3. Regular oil checks: Engine oil is a crucial lubricant for smooth component operation. Beyond routine maintenance, conduct periodic oil inspections yourself. Ensure the oil level on the dipstick stays within normal range—neither too high nor too low. This is particularly important for older vehicles, which require more frequent checks.
