Emergency shut off system
When a certain level of impact is detected by the impact sensor, the emergency
shut off system blocks the high voltage current and stops the fuel pump to mini-
mize the risk of electrocution and fuel leakage. If the emergency shut off system
activates, your vehicle will not restart. To restart the hybrid system, contact your
Lexus dealer.
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 message is shown on the
multi-information display, read the
message and follow the instructions.
( P. 406)
If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
■
connected
The hybrid system may not start. In this case, try to start the system again. If the "READY"
indicator 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. 402,
406) go off. If there is only a small amount of fuel, the hybrid system may not be able to
start. (The standard amount of fuel is about 2.6 gal. [10.0 L, 2.2 Imp.gal.] [except F
SPORT models] or 2.6 gal. [9. 9 L, 2.2 Imp.gal.] [F SPORT models], when the vehicle is
on a level surface. This value may vary when the vehicle is on a slope. Add extra fuel
when the vehicle is inclined.)
Electromagnetic waves
■
High voltage parts and cables on hybrid vehicles incorporate electromagnetic shield-
●
ing, and therefore emit approximately the same amount of electromagnetic waves as
conventional gasoline powered vehicles or home electronic appliances.
Your vehicle may cause sound interference in some third party-produced radio parts.

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 condi-
tions.
