th e interaction of vehicle sy stems with electronic
medical aids such as cardiac pacemakers. In addition,
there are components ins talled in

tus of theve hicle, can generate magnetic fields
on a par with permanent magnets. These fields
can be found, forex ample, in the area around
th e multimedia and sound sy stem or also in the
area of the seats, depending on theve hicle
equipment.
Fo rth is reason, thefo llowing can occur in isola‐
te d cases, depending on the aids used:
R Medical aids malfunctioning
R Adverse health ef fects
Obser vethe no tes and warnings of the manufac‐
turer of the medical aids; if in doubt, conta ctthe
device manufacturer and/or your doc tor.If th ere
is continuing uncer tainty concerning the possi‐
bility of medical aids malfunctioning, Mercedes-
Benz AGrecommends using only few electrical
