holy crap you are right. I just tested it and watched the a/c engage
because I didn't really believe it, and the manual says 'if so equipped' and
since I got an almost rock bottom base model, I was convinced there were no
freebies here. the 4runner always goes to full a/c when you press defog but the
a/c lights up too...yaris doesn't light but compressor certainly starts
