Mercedes-Benz AGcannot, despite carefully
de veloping vehicle systems, comple tely rule out
th e interaction of vehicle systems with elect ronic
medical aids such as card iac pacemakers.
In addition, there are components installed in the
ve hicle that, rega rdless of the operating status of
th eve hicle, can generate magnetic /elds on a par
with permanent magnets. These /elds can be
fo und, forex ample, in the area around the multi-
media and sound system or also in the area of the
seats, depending on theve hicle equipment.
Fo rth is reason, thefo llowing can occur in isolated
cases, depending on the aids used:
R Medical aids malfunctioning
R Adve rse health e.ects
Obser vethe no tes and warnings of the manufac-
turer of the medical aids; if in doubt, contact the
device manufacturer and/or your doctor. If there
is continuing uncer tainty concerning the possibil-
ity of medical aids malfunctioning, Mercedes- Benz
AGrecommends using only fewelectrical
ve hicle systems and/or main taining a distance
