Experienced a Deliberate Fuel Shortage in My 2025 RAV4 Plug-in Hybrid Electric Vehicle
The 2025 Toyota RAV4 Prime, a plug-in hybrid vehicle (PHEV), offers the benefit of electric-only (EV) driving and hybrid operation. But how far can you go on EV mode after running out of gas? Let's delve into this interesting scenario.
Understanding the RAV4 Prime System
The RAV4 Prime can travel approximately 42 miles on electric power alone (based on EPA ratings, although real-world use may vary). When the gasoline tank is empty, the vehicle can continue to drive using its battery-powered EV mode until the EV range is depleted. However, it's important to note that once the battery is drained, the vehicle cannot continue to drive, as there is no mechanical connection to the wheels except through the electric motors and hybrid powertrain.
Unlike conventional hybrids, the RAV4 Prime does not have a gasoline engine backup once the tank is empty. The "buffer" in this context is simply the remaining EV-only range. There is no additional hidden range beyond what the EV mode estimates—once that is consumed, propulsion ceases.
Practical Implications
If you receive an empty tank warning, you have only the remaining EV mode range left as a “buffer.” If your EV mode shows about 25 miles, that is your maximum additional driving distance. There is no hidden buffer of gasoline—your electric-only distance is your only reserve. The system is designed to alert you to refuel before total propulsion loss.
Summary Table
| Scenario | Available Buffer Distance | Notes | |---------------------------|------------------------------------|--------------------------------------------------| | After empty tank warning | Remaining EV mode range (~25 mi) | No additional gasoline buffer—EV is last resort | | After EV mode is depleted | 0 miles | Vehicle cannot drive further without fuel or charge |
A Word of Caution
For maximum safety, plan for recharging or refueling as soon as possible after the fuel warning appears. Familiarity with a scan tool may be useful for addressing potential codes that might arise when the vehicle runs out of gas or when the EV level is nearly depleted.

In the scenario of driving a 2025 Toyota RAV4 Prime, the remaining electric-only range (approximately 25 miles) serves as the "buffer" once the gasoline tank is empty. This is because there is no additional gasoline buffer beyond what the EV mode estimates in this vehicle.
When the EV mode is depleted, the vehicle cannot drive further without fuel or a charge, making it crucial to plan for recharging or refueling as soon as possible after receiving an empty tank warning.
