ENGLISH
When you install the mounting device or mobile holder, ensure that
they do not interfere with or hinder the steering or braking systems
or other systems used in the operation of the vehicle (for example,
airbags) or disturb your field of vision while driving.
Check that the deployment of the airbag is not blocked or impaired in
any way.
Ensure that the mounting device or mobile holder is not installed
where you might come in contact with it in the event of an accident
or collision.
Periodically check that the suction cup at the bottom of the
mounting device is firmly attached to the windscreen, especially if
the ambient temperature changes a lot.
Never leave the mounting device inside the vehicle in direct sunlight
or in excessive heat. The mounting device and suction cup may be
damaged and adhesion may be impaired if the inside temperature
exceeds +70°C (160°F).
