Hybrid Battery (Traction Battery) Air Vents; Emergency Shut Off System; Hybrid Warning Message - Lexus GS450h Owner's Manual

Hybrid battery (traction battery) air vents

There are air intake vents on the
both sides of the rear seatback for
the purpose of cooling the hybrid
battery (traction battery). If the
vents become blocked, the hybrid
battery may overheat, leading to a
reduction in hybrid battery output.

Emergency shut off system

When a certain level of impact is detected by the impact sensor, the emer-
gency shut off system blocks off the high voltage current and stops the fuel
pump to minimize the risk of electrocution and fuel leakage. If the emer-
gency shut off system activates, your vehicle will not restart. To restart the
hybrid system, contact your Lexus dealer.

Hybrid warning message

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 instruc-
tions. P. 513)
