SMART ENTRY SYSTEM AND PUSH-BUTTON START The GS450h smart entry system consists of a smart key transceiver that communicates bi-directionally enabling the vehicle to recognise the smart key in close proximity to the vehicle. Once recognised, the smart key will allow the user to lock and unlock the doors without pushing smart key buttons, and start the vehicle without inserting it into an ignition switch.

SMART ENTRY SYSTEM AND PUSH-BUTTON START Vehicle Starting/Stopping The smart key has replaced the conventional metal cut key, and the power button with an integral status indicator light has replaced the ignition switch. The smart key only needs to be in proximity to the vehicle.
HYBRID SYNERGY DRIVE OPERATION Once the READY indicator is illuminated in the instrument cluster, the vehicle may be driven. However, the petrol engine does not idle like a typical vehicle and will start and stop automatically. It is important to recognise and understand the READY indicator provided in the instrument cluster.

EMERGENCY RESPONSE Extrication (Continued) • Stabilise Vehicle Check/stabilise at (4) points directly under the front and rear pillars. Do not place blocks under the high voltage power cables, exhaust system, or fuel Chocking Points system. Chocking /Stabilising Points • Access Patients Glass Removal Use normal glass removal procedures as required.
EMERGENCY RESPONSE Extrication (Continued) Rescue Lift Air Bags Responders should not place chocks or rescue lift air bags under the high voltage power cables, exhaust system, or fuel system. Repositioning Steering Wheel and Seat Power tilt/telescopic steering wheel and seat controls are shown in the illustration.
EMERGENCY RESPONSE WARNING: • The NIMH battery electrolyte is a caustic alkaline (pH 13.5) that is damaging to human tissues. To avoid injury by coming in contact with the electrolyte, wear proper personal protective equipment. • The battery modules are contained within a metal case and accessibility is limited.
Clean up of the HV battery pack can be accomplished by the vehicle recovery crew without further concern of runoff or spillage. For information regarding recycling of the HV battery pack, contact the nearest Lexus dealer or Lexus Australia. – 20 –...
Spills The GS450h contains the same common automotive fluids used in other non-hybrid Lexus vehicles, with the exception of NiMH electrolyte used in the HV battery pack. The NiMH battery electrolyte is a caustic alkaline (pH 13.5) that is damaging to human tissues.
EMERGENCY RESPONSE First Aid Emergency responders may not be familiar with a NiMH electrolyte exposure when rendering aid to a patient. Exposure to the electrolyte is unlikely except in a catastrophic crash or through improper handling. Utilise the following guidelines in the event of exposure. WARNING: The NIMH battery electrolyte is a caustic alkaline (pH 13.5) that is damaging to human tissues.
