in the engine compartment. During PDS, reinstall the D/C cut fuse (30A) to its original location
and confirm ALL related Diagnostic Trouble Codes (DTCs) are cleared.

Customize ACC Function

The pre-startup function detects when a user enters the vehicle and energizes the audio head
unit (+BA) so that the multimedia system can quickly be used. This function is not enabled at the
factory to reduce parasitic current draw in transit and storage. To enable this function, it is
necessary to set the ACC customization function in the navigation display to OFF within the
GTS+ software.
1. Turn the engine switch (power switch) to the ON position (ON mode).
2. Enter the following menus: Settings – Vehicle Customization – Utility – ACC Customize.
3. Change the setting to OFF (toggle at left with gray background).

Enable Hybrid Battery Thermal Keep Control Mode

HV/BEV battery may be frozen in extremely cold areas. As a result, the HV/BEV battery may
become excessively weak, and the system may NOT be able to be started. By enabling HV/BEV
Battery Thermal Keep Control Mode, it is possible to warm the HV/BEV battery and maintain its
current temperature in order to prevent it from becoming excessively weak.
When this mode is set to ON, the timer charging settings are canceled at temperatures of 14°F
(-10°C) or lower. Charging will begin immediately when the charging cable is connected to
the vehicle.
Table 1. HV/BEV Battery Thermal Keep Control Mode

 To prevent the HV/BEV battery from
freezing when a charging start time is set,
when the HV/BEV Battery Thermal Keep
Mode is enabled, the charging timer will
