681-4. Hybrid system
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.

outside the vehicle may enter into and 
accumulate in the air conditioning sys-
tem. This may then cause odor to be 
emitted from the vents.
●To reduce potential odors from occur-
ring:
• It is recommended that the air condition- ing system be set to outside air mode 
prior to turning the vehicle off.
• The start timing of the blower may be  delayed for a short pe riod of time imme-
diately after the air conditioning system is 
started in automatic mode or with the 
micro dust and pollen filter on.
