Published availability and qualifications
Verified for all 2025 U.S. RZ 300e and RZ 450e grades during an active charging session.
Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Connect the charging cable and confirm that AC or DC charging has started.
- 02
While charging, turn the power switch to ON.
- 03
When the My Room Mode prompt appears automatically, select Yes within approximately 100 seconds.
- 04
Use the climate control, audio and other permitted electrical equipment while monitoring the charge state.
- 05
Turn the power switch off to end My Room Mode; during DC charging it also ends automatically when DC charging completes.
Important limits
- My Room Mode lengthens charging time and can lower the final charge during DC charging.
- Starting it while a charging schedule is waiting ignores the schedule and starts charging immediately.
- Never leave children, people needing care or pets unattended; climate can stop if the traction battery reaches its lower limit.
Quick checks.
- ✓If the prompt disappears, turn the power switch off, confirm charging is active and repeat; the switch turns off after about 100 seconds without a selection.
- ✓If climate stops because traction-battery charge is too low, turn the power switch off and wait for charge to increase before restarting the mode.
- ✓A yellow electric-power-steering warning during charging can occur without indicating a My Room Mode malfunction, as documented by Lexus.
