(1)检查轮胎气压。轮胎要保持较高的气压,充气压力一般应比规定值高100～150kPa,但不要超过最高压力。气压过高或不足,都会增加行驶阻力,使油耗升高。
(1) Check the tire pressure. Tires to maintain a high pressure, inflation pressure should generally be higher than the specified value 100 ~ 150kPa, but do not exceed the maximum pressure. If the pressure is too high or too low, it will increase the driving resistance and increase the fuel consumption.
