What is the normal tire pressure for the Mercedes-Benz A200L?
1 Answers
The normal tire pressure for the Mercedes-Benz A200L is between 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. The Mercedes-Benz A200L is equipped with an active tire pressure monitoring system. The vehicle typically displays the specific tire pressure values for each tire, which can be viewed on the onboard computer. Simply press the SET button located in front of the gear lever to clearly see the tire pressure. If the corresponding dashboard light turns on and then off after pressing the SET button, it indicates normal tire pressure. If the light stays on, it indicates abnormal tire pressure. Generally, a tire pressure above 2.8 bar is considered too high, while a pressure below 2.0 bar is too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; weakens the function of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction between the tire and the ground, rapidly raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside) turns on, there are generally three possible reasons: Abnormal tire pressure: Usually triggers an alarm when below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the indicator light to turn on. Simply reset the tire pressure to resolve this. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If damaged during driving, it can cause the tire pressure fault light to turn on. For sensor damage, replacement with a new part is the only solution.
