It comes up on the left hand side panel. (see page 2-10 "Instrument controls" of your owners manual) If this light comes on, that's the one you need to worry about, take it too your dealer, before you need to tow it.
Your's may just be a weak battery in the key fob, in that case replace with a CR2032.
