Warning!
In order to avoid distraction which could
lead to an accident, the driver should
enter system settings with the vehicle at
a standstill and operate the system only
when road and traffic conditions permit.
Always pay full attention to traffic condi
tions first before operating system con
trols while driving.
Bear in mind that at a speed of just
30 mph (approximately 50 km/h), your
vehicle is covering a distance of 44 feet
(approximately 14 m) every second.
G
Warning!
Always select a volume that allows you to
still hear ambient sound in your immedi
ate vicinity (e.g. horns, emergency res
cue vehicles, police vehicles, etc.). You
could otherwise cause an accident.

Warning
If you wish to have a radio other than an
original smart radio fitted in your vehi
cle, please always have the necessary
work performed at an authorized smart

This is particularly important if your ve
hicle is fitted with a radio preinstallation.
Improper connection can result in the
failure of important vehicle functions,
thereby endangering the operating
safety of your vehicle and thus your own
safety and that of other people.
