For safety and security
There are air intake vents under the 
rear seats for the purpose of cooling 
the hybrid battery (traction battery). If 
the vents become blocked, the hybrid 
battery input and output may be 
restricted, leading to a reduction in 
hybrid battery (traction battery) out-
put.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 minimize the risk of electrocu-
tion 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 
when a malfunction occurs in the 
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the 
multi-information display, read the 
message and follow the instructions.

NOTICE
■Hybrid battery (traction battery) air 
intake vents
●Make sure not to block the air intake 
vent with anything, such as a seat 
cover, plastic cover, or luggage. If the 
vents become blocked, the hybrid bat-
tery (traction battery) input and output 
may be restricted, leading to a reduc-
tion in hybrid battery (traction battery) 
output and a malfunction.
●When dust etc. has accumulated in the 
air intake vent, periodically clean it 
with a vacuum cleaner to prevent the 
vent from clogging.
●Filters are installed to the air intake 
vent. When the filters remain notice-
ably dirty even after cleaning the air 
intake vent, filter cleaning or replace-
ment is recommended. When clean-
ing or replacing the filters, contact 
your Lexus dealer. 
Refer to P.279 for details on how to 
clean the filters.
●Do not get water or foreign materials
