What does it mean that the temperature outside the car is low on the dashboard?

It shows that the temperature outside the car is low, just to remind the driver that the temperature outside the car is low, beware of road icing and drive carefully.

When the car is driving in an environment where the temperature is lower than 4 degrees Celsius, the outdoor temperature sensor measures the outdoor temperature and transmits it to the instrument, which will light a snowflake lamp to warn the driver to drive carefully.

Generally, the snow light on the instrument is yellow at 0-4 degrees Celsius, and the snow light on the instrument panel is red below 0 degrees Celsius, which is a reminder light and does not affect the normal use of the vehicle.

Extended data:

1, it is necessary to warm the car in winter.

It's cold, and many experienced car owners know it's time to warm up their cars. Because the temperature is low in winter, the engine is not easy to reach normal temperature, the viscosity of lubricating oil will increase and the lubrication effect will decrease, so the idle speed will rise to more than 1000 rpm when starting. When the idle speed drops to normal speed, it is enough to warm the car.

Braking should be "early" and "soft" in snowy days

In winter, the temperature drops suddenly, and sometimes there will be a layer of frost or thin ice on the brake disc, which will seriously cause the brake calipers to fail to close. Therefore, when driving in cold weather, check the braking system. After the vehicle starts, you should lightly step on the brakes and check whether the brakes are normal, so as to avoid being caught off guard when there is a problem.

Because the tires and the road surface are hard in winter, it is better to pedal the brakes earlier in winter and cooperate with the downshift brake. On the ice and snow road, try not to step on the brakes, but use downshifting to brake the engine.
