What does it mean that BMW 525 shows the outdoor temperature of 3.0c?

This is to remind drivers that the temperature outside is low, beware of road icing and drive carefully. Cars with this function will generally remind you when the outside temperature is below 4 degrees Celsius, in case the driver can't feel the change of the outside temperature inside the car.

When the outdoor temperature is too low and the car is driving in an environment with the temperature below 4 degrees Celsius, the outdoor temperature sensor measures the outdoor temperature and transmits it to the instrument, which will light the snow lamp to warn the driver to drive carefully.

Extended data:

1. When driving in winter, you must warm up the vehicle first, because it is cold in winter, and all parts of the vehicle need to be warmed up, which will greatly improve the service life of the vehicle. The preheating time is suggested to be three to five minutes.

2. When driving in winter, we should first observe the surrounding conditions to avoid accidents, because the roads are slippery in winter, and once there is sudden braking or any unexpected situation, there is no good control environment as usual. Observing the surrounding environment will greatly reduce the occurrence of accidents.

When driving in snowy days, you must slow down and observe the road conditions. Be sure to keep a safe distance from the car in front. In order to prevent rear-end collision, remember not to slam the steering wheel and make sharp turns when driving in snowy days. Driving slowly and smoothly in snowy days is the safest way to drive.

4. When parking in winter, you should also pay attention to choosing a good parking place. Try not to stop in low-lying and humid places to prevent stagnant water from freezing the wheels. Also, don't park your car on a snowy slope to prevent it from falling when you start the car.
