1-1. Hybrid system
Hybrid warning message
A message is automatically displayed when a malfunction occurs in the
hybrid system or an improper operation is attempted.
If a warning light comes on or a warning message is displayed, or the 12 volt bat-
■
tery is disconnected
The hybrid system may not start. In that case, try to start the system again. If the
"READY" light does not come on, contact your Lexus 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. 536) 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 2. 9 gal. [11 L, 2.4 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 style and
driving conditions.
