Warning
<<High voltage>>
•  If the necessary measures are not taken before servicing an electric vehicle, it could cause electrical shock and result in serious injury or, in the worst case, death. Before servicing the electric vehicle, refer to [HIGH VOLTAGE SERVICE CAUTIONS] in the general information and implement the necessary measures. (See HIGH VOLTAGE SERVICE CAUTIONS.)

High Voltage Part Inspection And Removal/Installation Notes

Warning
<<High voltage>>
•  The inspection and removal/installation of the high voltage parts of this vehicle must be performed by persons who have acquired qualifications specified by the laws and regulations.
•  The protective equipment indicated in the workshop manual is recommended by Mazda. Use equipment specified by the laws and regulations of each country.
•  Wear insulated gloves when inspecting or removing/installing the high voltage parts. Touching the high voltage parts without wearing insulated gloves could cause electrical shock and result in serious injury or, in the worst case, death. (See HIGH VOLTAGE SERVICE CAUTIONS.)
•  Before inspecting or removing/installing the high voltage parts, remove the service plug and wait until 10 min have elapsed. Servicing without removing the service plug or before 10 min have elapsed after removing the service plug could cause electrical shock and result in serious injury or, in the worst case, death. (See SERVICE PLUG REMOVAL/INSTALLATION.)
•  Do not spin the tires while inspecting or removing/installing the high voltage parts. If the tires spin, power generation occurs even if the service plug is removed. If power generation occurs, it could cause electrical shock and result in serious injury or, in the worst case, death.
•  Verify that the charging connector is not connected to the vehicle when inspecting or removing/installing the high voltage parts. If the charging connector is connected to the vehicle, high voltage may be supplied to the vehicle. If this occurs, it could cause electrical shock and result in serious injury or, in the worst case, death.
•  Always observe the following thoroughly to ensure safety when inspecting or removing/installing the high voltage parts. Otherwise, the high voltage circuit may operate on the vehicle regardless of whether or not the main power is switched OFF or ON (READY off or on). If this occurs, it could cause electrical shock and result in serious injury or, in the worst case, death.
―  Do not perform normal charging or quick charging
―  Do not select high voltage battery cooling on center display after EV system stops
―  Do not open/close doors frequently with main power switched OFF
―  Switch to connected vehicle maintenance mode (MyMazda App connected vehicle)
―  Cancel climate control timer
―  Operate center display and turn off battery heater operation
•  When inspecting or removing/installing the high voltage parts, place a high voltage work sign on the vehicle to alert other workers. (See HIGH VOLTAGE SERVICE CAUTIONS.)
Caution
<<High voltage>>
•  Do not switch the main power ON (READY on) after removing the service plug. If the main power is switched ON (READY on) after removing the service plug, a malfunction may occur with the vehicle.
Note
•  The high voltage parts can be identified as follows.
―  Parts that are connected using orange wiring harnesses
―  Parts with a high voltage warning label attached
