PRECAUTIONS
The RX450h has unique operating modes, so always follow the precautions below when per-
forming the PDS operation:
• The RX450h contains high voltage (288-650 volts) AC and DC Systems. All high voltage
wiring and connections are orange in color. Do not carelessly touch these orange colored
wiring harnesses and connectors.
• The hybrid system may start up and shut down suddenly whenever the "READY" light is
illuminated. Be sure to put the selector lever in "P", apply the parking brake, and se-
lect the "POWER" switch in the OFF in order to stop the hybrid system (the
"READY" light goes OFF), before working in the engine compartment.
• The hybrid transaxle, engine radiator, and inverter radiator may reach high temperatures
during inspection. Carefully observe all caution labels and instructions on these compo-
nents.
• Be sure to keep the selector lever in "P" at all times unless otherwise instructed. When the
selector lever is in "N", the hybrid vehicle battery will not charge even if the gasoline en-
gine is operating.
• When leaving the vehicle, put the selector lever in "P", apply the parking brake, and push
the "POWER" switch in the OFF in order to stop the hybrid system (the "READY" light
goes OFF).
• Air vents are located under the rear seats to cool the hybrid vehicle battery. Do not block
these air vents.
• Do not splash water on the electric components in the engine compartment.
