IMPORTANT
An LCD panel and/or video monitor may be installed in a motor vehicle
and visible to the driver if the LCD panel or video monitor is used for
vehicle information, system control, rear or side observation or naviga-
tion. If the LCD panel or video monitor is used for television reception,
video or DVD play, the LCD panel or video monitor must be installed so
that these features will only function then the vehicle is in ‘park’ or when
the vehicle’s parking brake is applied.
An LCD panel or video monitor used for television reception, video or
DVD play that operates when the vehicle is in gear or when the parking
brake is not applied, must be installed to the rear of the driver’s seat
where it will not be visible, directly or indirectly, to the operator of the
