Expanding on what TX5 said above...you have heated mirrors (see AUTOMATIC HEATING in the middle column from owners manual below).
(If a heading in the owners manual has an asterisk
"*" then it is an optional item (all models may not have it)
But do you have EC (electrochromatic/auto dimming) mirrors? One way to tell the difference is to note if there's a thick black band around the circumference of the mirror glass...the EC mirror do...the plain heated mirrors don't (see image below of EC mirrors):
Aspherical (wide angle), EC (auto dimming), heated mirror glass w/thick black band around circumference {Euro option}
EC/heated mirrors - driver's side (plain), passenger side (convex) {USA option}
plain heated mirror glass (does not have thick black band)
And if you can see the rear of the mirror glass...the heated mirror will have the two leads in the upper corner for the two wires that connect to the heating element...and if you have EC mirrors...there will be the additional harness (note the one with purple wire):
