Does the 2005 RL have a temperature warning light that comes on when the temperature falls below a certain reading? I ask because previous cars I have owned do have such a light.

I found such as warning valuable as it made me alert to ice on the road.

 

I don't think so... but you can just look down and see the temp. It makes sense to have such a warning though, because people don't always look at the current temp outside.
