The reasons for the car rolling when in P gear are: 1. The driver did not step on the brake or pull the handbrake, causing the vehicle to roll due to inertia; 2. Insufficient power when the car is idling or in neutral, or the slope is too steep, leading to the vehicle rolling when in D gear due to lack of power; 3. Delayed power response when releasing the brake and stepping on the accelerator, causing the car to roll. Precautions for driving an automatic transmission car are: 1. Do not shift into P gear while driving; 2. After driving, the engine must be turned off and shifted into P gear before the key can be removed; 3. Do not shift into N gear to coast while driving; 4. When starting the vehicle in P or N gear, remove the gear lever from P gear while stepping on the brake, turn on the power, step on the brake, shift to N gear, and after ignition, shift into D gear to move forward directly.

How to reset the tire pressure light on a 2009 Lavida?

Tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top, four small spikes at the bottom, and an exclamation mark inside. The illumination of the tire pressure monitoring indicator indicates abnormal tire pressure. Abnormal tire pressure is generally caused by the following reasons: Abnormal tire pressure: Usually, an alarm will sound if the pressure is 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 tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to light up. In this case, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged during driving, it will also cause the tire pressure warning light to illuminate. For sensor damage issues, only a replacement with a new part is possible.

What is the appropriate tire pressure for the front tires?

The air pressure for the front tires generally depends on the season. In summer, the tire pressure for the front tires is usually set at 2.3 bar, while in winter, it is typically set at 2.5 bar. According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum pressure should not exceed 3.5 bar. Normal tire pressure values in winter: In winter, the tire pressure should be based on the standard tire pressure for the vehicle, with an appropriate increase of about 0.2 bar. Normal tire pressure values in summer: Generally, the lower limit of the standard tire pressure for the vehicle is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can usually be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures.

What to Do When the Fuel Tank Cap Won't Open?

Solutions for a fuel tank cap that won't open: Check if the cap is stuck or if the hinges are rusty. You can insert a small wooden piece into the gap of the fuel tank cap to pry it open while pulling the release switch. If the fuel tank cap spring has lost its elasticity, you can add a small spring to the rubber pad on the fuel tank to increase the elasticity between the cap and the locking mechanism. Some cars have thinner sheet metal, which may cause the fuel tank cap to be misaligned. In this case, take it to a repair station for realignment. If the fuel tank cap hinges or the locking mechanism are worn out, apply lubricant to these areas. If the fuel tank cap is frozen due to cold weather or too dirty to open, address the issue first before attempting to open it to avoid secondary damage.

Is a Tire Pressure of 2.1 Normal?

A tire pressure of 2.1 bar is considered normal in summer. Generally, the standard tire pressure for common sedans ranges from 2.2 to 2.5 bar, but this should be determined based on specific conditions. The standard tire pressure range for your vehicle can usually be found in the user manual or on the central pillar or fuel tank cap. Winter tire pressure: It is advisable to increase the standard tire pressure by approximately 0.2 bar. Summer tire pressure: If the car is parked outdoors, the pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. Light load tire pressure: Use the lower limit of the standard tire pressure. Full load tire pressure: When fully loaded, use the upper limit of the standard tire pressure.
