Your vehicle is equipped with infrared re-
flecting glass which reduces the amount of
radiated heat entering the interior through
the windows.
The infrared reflecting glass also prevents
the transmission of signals through the
glass by in-vehicle electronic devices (e.g.
electronic toll collection devices).
To allow the use of these devices in the ve-
hicle, two infrared transparent areas
(1 and 2) are placed in the windshield.
