1-1. Hybrid system
■Hybrid battery air vent
Hybrid battery air vent
There is an air intake vent on the
package tray for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent becomes
block
ed, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
Emergency shut off system
The emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of el ectrocution and fuel leakage
when a certain level of impact is detected by the impact sensor. If the
emergency shut off system activates, yo ur vehicle will not restart. To
restart the hybrid system, contact your Lexus dealer.
Energy monitor/consumption screen
You can view the status of your h ybrid system on the multi-information
display ( P. 117) and the touch screen( P. 1 8 2 ). The following images

■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 sy stem again. If the
“READY” light does not come on, contact your Lexus dealer.
CAUTION
■High voltage precautions
The vehicle has high voltage DC and AC systems 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 and
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 caution labels attached to the vehicle.
●Never try to open the service plug acce ss hole located in the luggage compart-
ment. The service plug is used only when the vehicle is serviced and is subject to
high voltage.
