■Refilling fuel
Plug-in hybrid vehicles can be driven using electricity charged from an exter-
nal power source, however the gasoline engine that is provided on board as
an auxiliary power source and as a power source for driving in HV mode
needs to be filled with fuel. Check the fuel amount and refill immediately
when the fuel level becomes low. ( P. 174)
■ Gasoline engine operation in EV mode
Even if there is a sufficient amount of electricity remaining in the hybrid bat-
tery (traction battery) and EV driving range ( P. 58, 268) is being displayed,
the gasoline engine may operate automatically in the following circum-
stances (EV driving will be returned to automatically after EV driving
becomes possible again):
● When the heater etc. is in use.
● When the temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high
speeds, etc.
● When the temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 32 °F (0 °C)
for a long period of time etc.
● When power is needed temporarily, for example when accelerating sud-
denly.
● When vehicle speed is more than approximately 62 mph (100 km/h).
● When the accelerator pedal is depressed firmly or the vehicle is on a hill
etc.
● When the outside temperature is low (less than 14 °F [-10 °C])
The gasoline engine may also operate in circumstances other than those
listed above, depending on conditions.

Hybrid warning messageA message is automatically displayed when a malfunction occurs in
the hybrid system or an impr oper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. ( P. 546)
■If a warning light comes on, a warn ing message is displayed or the 12-
volt battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dealer.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be
started, refuel the vehicle with at least enough gasoline to make the low fuel
level warning light ( P. 537) go off. If there is only a small amount of fuel,
the hybrid system may not be able to start. (The minimum amount of fuel to
add to make the low fuel level warning light go out is about 1.9 gal. [7.1 L,
1.6 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)
