1Traffic Sign Recognition System
To help reduce the likelihood that high interior
temperatures will cause the camera's sensing system
to shut off, when parking, find a shady area or face
the front of the vehicle away from the sun. If you use
a reflective sun shade, do not allow it to cover the
camera housing.
Covering the camera can concentrate heat on it.
If appears, the Traffic Sign Recognition System
does not work, and will be displayed.
•
Use the climate control system to cool down the
interior and, if necessary, also use demister mode
with the air flow directed towards the camera.
•
Start driving the vehicle to lower the windscreen
temperature, which cools down the area around
the camera.
If appears, the Traffic Sign Recognition System
does not work, and will be displayed.
•
Park your vehicle in a safe place, and clean the
windscreen. If the message does not disappear
after you have cleaned the windscreen and driven
for a while, have your vehicle checked by a dealer.
