D/C Cut Fuse (30A) Installation

To minimize battery discharge during transportation and storage, the D/C cut fuse (30A) has
been removed at the assembly plant and temporarily stored in the blank space of the relay block
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.
Remove the D/C cut fuse (30A) from the blank space of the relay block in the engine
compartment and install the D/C cut fuse (30A) in the relay block as shown.

Head Unit System Reset

Before selling a Toyota vehicle, please confirm that the welcome screen with language options
appears on the head unit display when ignition is switched to the ON position. There may be
instances where the welcome screen with language options may not properly appear on the
head unit display.
If the welcome screen showing language options is not displayed, complete the following steps:
1.
2.
3.
4.

Select the Settings option (gear icon).
Scroll down and select the Info & Security option.
The System Reset dialogue box will appear. Select Reset to confirm the resetting of system.
Confirm that the welcome screen with language options is now displayed.

Seating Position Control ECU Initialization

Refer to the applicable Repair Manual for the seating position control ECU initialization
procedure (procedure 3).

Power Back Door Initialization

As a result of removal of the D/C cut fuse with the back door opened, the “automatic open and
close” function of the power back door will be inoperative due to loss of the back door position
memory stored in the computer. Therefore, it is necessary to initialize the power back door
during PDS.
If the D/C cut fuse is removed with the back door closed, the initialization is not required,
because the back door position memory is still stored in the computer. If the welcome screen
showing language options is not displayed, complete the following steps:
1.
2.
3.
4.

Close the back door completely by hand.
Check that the back door fully opens and fully closes.
Check that the power door main switch is in the ON (Operative) position.
Check that the back door fully opens and fully closes by operating the power back door
switch, the power back door closer switch, or the transmitter switch.

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.
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/EV battery may be frozen in extremely cold areas. As a result, the HV/EV battery may
become excessively weak, and the system may NOT be able to be started. By enabling HV/EV
Battery Thermal Keep Control Mode, it is possible to warm the HV/EV 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/EV Battery Thermal Keep Control Mode
PURPOSE

Prevent HV/EV
battery from freezing

CONDITION

OPERATION

 Ambient temperature is 14°F
(-10°C) or lower

 Begins to warm the HV/EV battery to
maintain its current temperature when the
ambient temperature drops to 14°F
(-10°C) or lower when the charging cable
is connected to the vehicle.

 Charging cable is connected
to vehicle

 To prevent the HV/EV battery from
freezing when a charging start time is set,
when the HV/EV Battery Thermal Keep
Mode is enabled, the charging timer will
be disabled, and charging will begin
immediately when the charging cable is
connected to the vehicle.

To enable HV/EV Battery Thermal Keep Control Mode, it is necessary to use GTS during PDS at
the dealership.
