you can open the windows by pressing and holding the unlock button.

if you dont have the USB adaptor for an MP3 player you sneak a
thin AUX cable through the any of the cracks of the center console.

if youre having trouble cleaning the cup holders, you can simply
remove the rubber part of the cup holders by squeezing it in the
middle and lifting.

if youre on the run, and you need a place where to put your
trunk seperator, you could put it on the floor, behind the driver
and passenger seats.

i dont know if you guys did this, but i bought a sticky pad and cut
it to fit the little flat space there is between the speed dials and
the steering wheel. thats where i put my fone.

I dont have anymore... thats about it.

Might have been mentioned elsewhere: if you want to leave your dog in the car, pressing the lock button twice locks the car and disables the interior motion sensor.

Or rather than going to mexico just buy a cable and recode it yourself.

Not sure it was already mentioned.
For cars without comfort access: insert the key fob in its slot, turn ON the engine then turn it OFF. Remove the key fob and now turn ON the engine. You only have about five seconds to do it.
Nice feature if you want to leave the car running and lock the doors too.
