721-2. Hybrid system
CT200h_OM_OM76215U_(U)
There is an air intake vent on the side of
the rear right seatback for the purpose
of cooling the hybrid battery (traction
battery). If the vent becomes blocked,
the hybrid battery may overheat, lead-
ing to a reduction in hybrid 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 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 your
Lexus dealer.
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.
