GS450h_300h_OM_OM30F00E_(EE)The installation of an
RF-transmitter system in your vehicle could affect electronic sys-
tems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
●Dynamic radar cruise control with full-speed range system
●Dynamic radar cruise control system
●Cruise control system
●Anti-lock brake system
●Vehicle dynamics integrated management
●SRS airbag system
●Seat belt pretensioner system
Be sure to check with any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional for precautionary measures or special instructions regarding
installation of an RF-transmitter system.
Further information regarding frequency bands, power levels, antenna positions and
installation provisions for the in stallation of RF-transmitters, is available on request at any
authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
High voltage parts and cables on the hybr id vehicles emit approximately the same
amount of electromagnetic waves as the conventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the reception of the radio frequency transmitter (RF-trans-
mitter).
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left as
they are, this may cause an accident such as fire. Be sure to have the systems of the SRS
airbag and seat belt pretensioner removed and disposed of by a qualified service shop or
by any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional before you scrap your vehicle.

761-2. Hybrid system
GS450h_300h_OM_OM30F00E_(EE)
◆When stopped/during start off
The gasoline engine stops
* when the vehicle is stopped. During start off, the
electric motor (traction motor) drives the vehicle. At slow speeds or when
traveling down a gentle slope, the engine is stopped
* and the electric motor
(traction motor) is used.
When shift lever is in N, the hybrid battery (traction battery) is not being
charged.
*: When the hybrid battery (traction battery) requires charging or the engine is warming up, etc., the gasoline engi ne will not automatically stop. (→P. 7 7 )
◆During normal driving
The gasoline engine is predominantly used. The electric motor (traction
motor) charges the hybrid battery (traction battery) as necessary.
◆When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the hybrid bat-
tery (traction battery) is added to that of the gasoline engine via the electric
motor (traction motor).
◆When braking (regenerative braking)
The wheel operate the electric motor (traction motor) as a power generator,
and the hybrid battery (traction battery) is charged.
■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
The EV indicator comes on when the vehicle is
driven using only the electric motor (traction
motor) or the gasoline engine is stopped.

For safety and security
■Conditions in whic h the gasoline engine may not stop
The gasoline engine starts an d 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

■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 dealer or repairer, or
another duly qualified and equipped professional.
■Charging the 12-volt battery
→ P. 5 5 4
■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 dealer or
repairer, or another duly qualified and equipped professional.
