The installation of an RF-transmitter system in your vehicle could affect electronic sys- tems such as:
●Hybrid system
●Multiport fuel injection system/seque ntial multiport fuel injection 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 de aler 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 ba nds, power levels, antenna positions and installation provisions for the installation of RF-transmitters, is available on request at any
authorized Lexus dealer or repairer, or anot her 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 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).

1-2. Hybrid system
The illustration is an example for explanation and may differ from the actual item.
Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics different from conven-
tional vehicles. Be sure you are closely familiar with the characteristics of your
vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and an electric
motor (traction motor) according to dr iving conditions, improving fuel effi-
ciency and reducing exhaust emissions.
Gasoline engine Electric motor (Traction motor)12

901-2. Hybrid system
RC300h_EE(OM24740E)
There is an air intake vent on the right
side of the rear seat back for the pur-
pose of cooling the hybrid battery
(traction battery). If the vent becomes
blocked, the hybrid battery may over-
heat, 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 the high voltage current and stops the fuel pump to mini-
mize 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 pro-
fessional.
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 dis-
connected
The hybrid system may not start. In this 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. 539) go off. If there is only a small amount of fuel, the hybrid system may not be able to start.(The standard amount of fuel is about 10 L [2.7 gal., 2.2 Imp. gal.] when the vehicle is on a
level surface. This value may vary when the vehi cle is on a slope. Add extra fuel when the vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid ve hicles incorporate electromagnetic shield- ing, 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 lim ited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi- tions.
■Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100 (Battery electric vehicle safety).

WARNING
■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 or connectors.
●If electric wires are exposed inside or ou tside 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 contact with your skin or
eyes, wash it off immediately with a large amount of water or, if possible, boric acid solution. Seek immediate medical attention.
●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 front wheels raised. If the wheels con-
nected to the electric motor (traction mot or) are on the ground when towing, the motor may continue to generate electricity. This may cause a fire. ( P. 530)
●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.

Warning lights inform the driver of malfunctions in the indicated vehicle systems.
*1: These lights turn on when the power switch is turned to ON mode to indicate 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 malfunct ion in a system if a light does not come
on, or turn off. Have the vehicle inspected by any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
