Hybrid warning message
A message is automatically displaye d 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. 508)
■If a warning light comes on or a wa rning 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 (
P. 499). 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 1.6 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.)
■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
