Ran across this warning in my owner’s manual (Subaru Forester). Don’t have a pacemaker, but I thought to make this warning more public, for those who do.
Keyless access with push-button start system (if equipped)
If you wear an implanted pacemaker or an implanted defibrillator, stay at least 8.7 in (22 cm) away from the transmitting antennas installed on the vehicle.
The radio waves from the transmitting antennas on the vehicle could adversely affect the operation of implanted pacemakers and implanted defibrillators.
The map (which took some searching to find) shows 6 antennae scattered through the interior and exterior. I can just see someone with this (poorly drawn) map and a ruler trying to find a safe zone to sit in the car… sure…
