GS450h_300h_OM_OM30F00E_(EE)
The main SRS airbag system components are shown above. The SRS airbag sys-
tem is controlled by the airbag sensor assembly. As the airbags deploy, a chemi-
cal reaction in the inflators quickly fills the airbags with non-toxic gas to help
restrain the motion of the occupants.

801-2. Hybrid system
GS450h_300h_OM_OM30F00E_(EE)
There are air intake vents on the both
sides of the rear seatback for the pur-
pose of cooling the hybrid battery
(traction battery). If the vents become
blocked, the hybrid battery may over-
heat, leading to a reduction in hybrid
battery output.
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 mini-
mize the risk of electrocution and fuel leakage. If the emergency shut off system
activates, your vehicle will not restart. To restart the hybrid system, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
A message is automatically displayed when a malfunction occurs in the hybrid
system or an improper operation is attempted.
If a warning message is shown on the
multi-information display, read the
message and follow the instructions.
