Vehicle warning lights are meant to alert you to failures or problems in different parts of your car. Thus, it shouldn't be surprising that different warning lights are connected to different weather patterns because the weather has a great effect on your car. For example, here are some warning lights you can expect to light up when the weather gets too cold:
Low Tire Pressure
If your car is fitted with a tire pressure monitoring system (most new vehicles are), then the warning light will come on when the pressure drops below the recommended pressure. It doesn't take a big pressure drop to trigger the warning. For example, a pressure drop of 5 psi, which may be caused by a temperature drop of 50oF, is enough to turn on the light. Luckily, this is easily solved by adjusting the tire pressure.
Brake
The brake monitoring system deals with the parking brake and the brake pressure. Therefore, the brake warning light (NOT the ABS warning light for the antilock brake system) will come on when there is a problem on either of these two areas. For example, it may light up if your car is leaking brake fluid or the parking brake fails to release completely.
What has this got to do with
Battery
If your car's battery is in a good condition and is operating as usual, then it isn't likely to freeze because a charged battery has an extremely low freezing temperature. However, cell damage, poor charging system or damage to the cells
Therefore, you need the intervention of a mechanic if the battery warning light comes on in extreme weather. The mechanic will check the condition of the battery system, such as the charging system and connections, and provide a suitable remedy.
Be on the lookout for these and other warning lights when the cold weather starts. Some of them may not be serious (such as low tire pressure), but some are and will cost you money. For example, if a frozen battery expands, it may cause a short between the plates and result in its permanent damage.
