Is there an opportunity
at PDI to test the
system?

No special action is required to activate at PDI other than the room fuse installation, which is
already part of the current PDI. We recommend checking for signal after installing room fuse.
See the image below for how the connectivity signal bar looks (it's the vertical stack bar on the
right bottom corner). This connectivity signal bar is not displayed on the "Home" screen, so the
PDI Inspector would have to go into the "Entertainment" or "Navigation" menu to check it. To
confirm it is working properly, the bar should be white like the image below.
The handbook states
that a “moderate
collision” will dial 911.
Please define
“moderate.”
If an airbag is deployed.
Will the customer
have to sign a
disclaimer for a loaner
vehicle that has
Connected
Services activated?
If the customer is downloading the MyMazda app to use the Connected Services functions,
they will sign the disclaimer as part of the MyMazda process. If the customer is not
downloading the app but the dealer has set it up for their own purposes (e.g., vehicle location),
then it is the dealer's responsibility to disclose to the customer.
