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 any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer.
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
