The air intake/discharge vents for the
hybrid battery (traction battery) are
located under the rear seats and in lug-
gage compartment respectively. If the
air intake vents are blocked, it could
lead to a reduction in hybrid battery
(traction battery) output.
*: RX450h
When a certain level of impact is detect ed 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.
A message is automatically displayed wh en 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.

■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. 662)
go off. If there is only a small amount of fu el, the hybrid system may not be able to start.
(The standard amount of fuel is about 2.9 gal. [11.0 L, 2.4 Imp.gal.], 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 ve hicles 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 li mited service life. The lifespan of the hybrid
battery (traction battery) can change in acco rdance with driving style and driving condi-
tions.
WARNING
■High voltage precautions
This vehicle has high voltage DC and AC sy stems as well as a 12-volt system. DC and
AC high voltage is very dangerous and can cause severe burns and electric shock that
may result in death or serious injury.
●Never touch, disassemble, remove or replace the high voltage parts, cables or their
connectors.
●The hybrid system will become hot after starting as the system uses high voltage. Be
careful of both the high voltage and the high temperature, and always obey the warn-
ing labels attached to the vehicle.
●Never try to open the service plug access
hole located under the rear seat. The service
plug is used only when the vehicle is serviced
and is subject to high voltage.
