901-2. Hybrid system
RC300h_EE(OM24740E)
There is an air intake vent on the right
side of the rear seat back for the pur-
pose of cooling the hybrid battery
(traction battery). If the vent becomes
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.
