Infrared reflective windshield

The infrared reflective windshield is coated and
prevents an excessive build-up of heat in the
vehicle interior.
The coating shields the vehicle interior against
radio waves up into the gigahertz range.
Radio-controlled equipment such as toll systems
can only be mounted on areas of the windshield
which are permeable to radio waves 1.
Areas permeable to radio waves 1 are best visi‐
ble from outside the vehicle when the windshield
is illuminated using an external light source.
