Infrared reflecting windscreen*
The infrared reflecting glass prevents the
vehicle interior from becoming too hot. It also
blocks radio waves up into the gigahertz
range.
Areas transparent to radio waves
1
In order to operate radio-controlled equip-
ment (e.g. toll recording systems), areas
on the windscreen are transparent to radio
waves. You can install radio-controlled sys-
tems here. These areas can best be seen from
outside the vehicle by observing the light
reflected off the windscreen.
