Published availability and qualifications
Verified for all 2023 U.S. Prius and Prius AWD grades. This is the regular hybrid Prius, not Prius Prime.
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
Start the hybrid system normally and wait for the READY indicator to illuminate.
- 02
If the gasoline engine is still cold, press the EV MODE switch before the engine begins its warm-up cycle.
- 03
Confirm that the EV drive mode indicator illuminates.
- 04
Accelerate gently and remain aware that speed, hills or a firm accelerator request can automatically restart the engine.
- 05
Press EV MODE again to cancel it, or continue normally if the vehicle cancels the mode itself.
Important limits
- EV drive mode is intended for short, low-load operation; Toyota describes a possible distance from a few hundred meters to about 0.6 mile depending on conditions.
- The mode may be unavailable when the hybrid system is hot or cold, the engine is warming, battery charge is low, speed is high, the accelerator is pressed firmly, the vehicle is on a hill or the windshield defogger is operating.
- The Acoustic Vehicle Alerting System may still produce sound, and pedestrians may not hear normal engine noise.
- Using EV mode more than necessary may reduce overall fuel economy.
Quick checks.
- ✓A buzzer or an EV Mode Unavailable message generally means one of the documented operating conditions is not satisfied.
- ✓If the mode cancels and the indicator flashes or goes out, reduce load and retry later after normal driving rather than treating automatic cancellation as a fault.
- ✓If a cold engine starts before the switch is pressed, allow the normal warm-up cycle to proceed.
