1-3. 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.

Do not carry large amounts of water

● Make sure not to block the air intake
vents 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 vents, periodically clean
them with a vacuum cleaner to prevent
the vents from clogging.
● Filters are installed to the air intake
vents. When the filters remain notice-
ably dirty even after cleaning the air
intake vents, filter cleaning or replace-
ment is recommended. When clean-
ing or replacing the filters, contact
your Lexus dealer.
Refer to P.315 for details on how to
clean the filters.
