Warning
-
<<High voltage>>
• Vehicles damaged in an accident could have electrical leakage due to internal damage of the high voltage battery. If servicing is carried out under electrical leakage conditions, it could cause electrical shock and result in serious injury or, in the worst case, death.
• Refer to [Handling high voltage battery on damaged vehicle] in [DAMAGED VEHICLE HANDLING] in the general information and determine if an internal inspection of the high voltage battery is necessary.(See
DAMAGED VEHICLE HANDLING [(E)].) Perform servicing only if an internal inspection of the high voltage battery is unnecessary. If it is determined that an internal inspection of the high voltage battery is necessary, contact the technical assistance for your market without performing servicing.

― Standard deployment control system: Without seat track position sensor
― Two-step deployment control system: With seat track position sensor
SAS control module
Handling
• When connecting or disconnecting the SAS control module connector, a person charged with static electricity could accidentally activate (deploy) the SAS air bag system. Before connecting or disconnecting the SAS control module connector, discharge any charged static electricity from your body.
• If the SAS control module is removed or the SAS control module connector is disconnected with the main power switched ON (READY off or on), the sensor in the SAS control module may activate, causing the SRS air bag system to activate (deploy) and cause injury. Before removing the SAS control module or disconnecting the SAS control module connector, always switch the main power OFF, disconnect the negative lead-acid battery terminal, and then wait for 1 min or more to allow the backup power supply of the SAS control module to deplete its stored power.
• Connecting the SAS control module connector without securing the SAS control module can cause the sensor in the SAS control module to malfunction, causing the SRS air bag system to unexpectedly activate (deploy) and cause injury. Therefore, before connecting the connector, securely fix the SAS control module to the vehicle.
Frontal or side collision
• When the SRS air bag system is activated (deployed) due to a collision, there is a possibility that the SAS control module may have an internal malfunction even though it does not appear to be damaged or deformed. If the SAS control module is reused, the SRS air bag system may not activate (deploy) properly and may cause a serious accident. When the following devices are activated (deployed), be sure to replace the SAS control module with a new module.
