GS450h_300h_OM_OM30D53E_(EE)The installation of an RF-transmitter system in your vehicle could affect
electronic systems 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 spe-
cial instructions regarding installation of an RF-transmitter system.
Further information regarding frequency bands, power levels, antenna posi-
tions and installation provisions for the installation 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 hybrid vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the radio frequency transmit-
ter (RF-transmitter).
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 professional before you
scrap your vehicle.

Hybrid system features
Gasoline engine
Electric motor (traction motor)
Your vehicle is a hybrid vehicle. It has characteristics different
from conventional vehicles. Be sure you are closely familiar with
the characteristics of your vehicle, and operate with care.
The hybrid system combines the use of a gasoline engine and an
electric motor (traction motor) according to driving conditions,
improving fuel efficiency and reducing exhaust emissions.

GS450h_300h_OM_OM30D53E_(EE)
For safety and security
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.
When a certain level of impact is detected by the impact sensor, the
emergency 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 emergency shut off system activates, your vehicle
will not restart. To restart the hybrid system, contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped
professional.
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
instructions.

If a warning light comes on, a warning message is displayed, or the 12-volt
battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level
warning light (P. 833) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The minimum amount of fuel to add
to make the low fuel level warning light go out is about 9.9 L [2.6 gal., 2.2
Imp.gal.], when the vehicle is on a level surface. This value may vary when
the vehicle is on a slope.)
Electromagnetic waves
High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount of
electromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
Your vehicle may cause sound interference in some third party-produced
radio parts.
Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.
Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100
(Battery electric vehicle safety).

CAUTION
Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
Pull your vehicle off the road, apply the parking brake, shift the shift lever
to P, and turn the hybrid system off.
Do not touch the high voltage parts, cables and connectors.
If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into con-
tact with your skin or eyes, wash it off immediately with a large amount of
water or, if possible, boric acid solution. Seek immediate medical atten-
tion.
If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using
even a small amount of water may be dangerous.
If your vehicle needs to be towed, do so with rear wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause an electricity leakage leading to a fire. (P. 822)
Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

*1: These lights turn on when the power switch is turned to ON mode to indi-
cate that a system check is being performed. They will turn off after the
hybrid system is on, or after a few seconds. There may be a malfunction in
a system if the lights do not come on, or turn off. Have the vehicle
inspected by any authorized Lexus dealer or repairer, or another duly qual-
ified and equipped professional.
