Install your own auto thermometer.

If it turns out your vehicle does not have a factory installed auto thermometer, you do not need to worry. There are many available models that you can purchase to easily install yourself. Some rest on the dash and plug into the cigarette lighter. Some stick to the dash and work with batteries. The most accurate models use an external sensor that is placed inside your door jam. Don't worry, the external sensor is really easy to install.

The auto thermometer keeps you aware of hazardous conditions.

It's fun monitoring the change in temperature while we traveling from one area to another. However an auto thermometer can be a safety feature if you live in a cool climate. Unfortunately, any time the temperature dips down around freezing, ice can develop on the roads. This is definitely a hazardous driving condition and knowing the outside temperature can help you to drive more cautiously to avoid a major accident.
