the hybrid system or an improper operation is attempted.
If a warning message is shown on the multi-information display, read
the message and follow the instructions. (

If a warning light comes on or a warning 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 go off (

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 1.6 gal. [6.0 L,
1.3 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)
