For safety and security
GS450h_300h_OM_OM30F92E_(EE)
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the extremely high speed deployment (inflation) by hot gases.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as theseats, the glove box, parts of the front and re ar pillars, and roof side rails may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●Vehicles with ERA-GLONASS: If the SRS ai rbags deploy, the system is designed to send an emergency call* to the Public Safety Answer ing Point (PSAP), notifying them
of the vehicle’s location (without needing to push the “SOS” button) and an agent will attempt to speak with the occupants to ascertain the level of emergency and assistancerequired. If the occupants are unable to communicate, the agent automatically treats
the call as an emergency and helps to di spatch the necessary emergency services. ( P. 384)
*: In some cases, the call cannot be made. (P. 386)
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set thresh- old level (the level of force corresponding to an approximately 20 - 30 km/h [12 - 18mph] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be cons iderably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the front of the vehicle “underrides”, or goes under, the bed of a truck
●Depending on the type of collision, it is possib le that only the seat belt pretensioners will activate.
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags w ill deploy in the event of an impact that exceeds the set threshold level (the level of force corresponding to the impact forceproduced by an approximately 1500 kg [3300 lb.] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate speed of 20 - 30 km/h [12 - 18 mph]).
●The SRS side and curtain shield airbags may also deploy in the event of a severe frontal
collision.

501-1. For safe use
GS450h_300h_OM_OM30F92E_(EE)
■Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags, SRS side and curtain shield airbags may also deploy if a serious impact occurs to the underside of your vehi cle. Some examples are shown in the illustra-
tion.
■Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags do not generally inflate if the vehicle is involved in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a
collision of any type causes sufficient forward deceleration of the vehicle, deployment of the SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard sur-
face
●Falling into or jumpin g over a deep hole
●Landing hard or falling
●Collision from the side
●Collision from the rear
●Vehicle rollover

GS450h_300h_OM_OM30F92E_(EE)
■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decelera- tion force can be obtained in conjunction with the recharging of the hybrid battery (trac-tion battery).
●The accelerator pedal is released while driving with the shift lever in D or S.
●The brake pedal is depressed while driving with the shift lever in D or S.
■EV indicator
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop automati- cally in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (traction battery) charging
●When the temperature of the hybrid battery (traction battery) is high or low
●When the heater is switched on
■Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the battery does not need to be charged from an outside source. However, if the vehicle is left parked for a
long time the hybrid battery (traction battery ) will slowly discharge. For this reason, be sure to drive the vehicle at least once every few months for at least 30 minutes or 16 km(10 miles). If the hybrid battery (traction battery) becomes fully discharged and you are
unable to start the hybrid system, contact any authorized Lexus retailer or Lexus autho- rized repairer, or any reliable repairer.
■Charging the 12-volt battery
 P. 533
■After the 12-volt battery has discharged or when the terminal has been removed and installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the hybrid battery (traction battery). If this continues for a few days, contact any authorized Lexus retailer orLexus authorized repairer, or any reliable repairer.
The EV indicator comes on when the vehicle is driven using only the electric motor (traction
motor) or the gasoline engine is stopped.

Hybrid system precautions
The illustration is an exam ple for explanation and may differ from the actual item.
Take care when handling the hybrid system, as it is a high voltage system
(about 650 V at maximum) as well as contains parts that become extremely
hot when the hybrid system is operatin g. Obey the warning labels attached to
the vehicle.

■Tachometer
Hybrid System Indicator switches to the tach ometer when driving mode is in sport mode. The settings of the tachometer display can be changed on the multi-information display.
( P. 111)
■Engine speed
On hybrid vehicles, engine speed is precis ely controlled in order to help improve fuel
efficiency and reduce exhaust emissions etc. There are times when the engine speed that is displayed may differ even when vehicleoperation and driving conditions are the same.
■Outside temperature display
●In the following situations, the correct outside temperature may not be displayed, or thedisplay may take longer than normal to change.
• When stopped, or driving at low sp eeds (less than 20 km/h [12 mph]) • When the outside temperature has changed suddenly (at the entrance/exit of agarage, tunnel, etc.)
• When the vehicle is parked in direct sunlight
●When “--” or “E” is displayed, the system may be malfunctioning.
Take your vehicle to any authorized Lexus re tailer or Lexus authorized repairer, or any reliable repairer.
