Approximately five hours after the hybrid system is turned off, you may hear sound com-
ing from under the vehicle for several minutes. This is the sound of a fuel evaporation
leakage check and, it does not indicate a malfunction.
A wide variety of non-genuine spare parts and accessories for Lexus vehicles are cur-
rently available in the market. You should kn ow that Toyota does not warrant these prod-
ucts and is not responsible fo r their performance, repair, or replacement, or for any
damage they may cause to, or adverse effect they may have on, your Lexus vehicle.

The installation of a mobile two-way radio system in your vehicle could affect electronic
systems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
●Dynamic radar cruise control system
●Anti-lock brake system
●SRS airbag system
●Seat belt pretensioner system

Be sure to check with your Lexus dealer for precautionary measures or special instruc-
tions regarding installation of a mobile two-way radio system.
High voltage parts and cables on the hybrid vehicles emit approximately the same
amount of electromagnetic waves as the co nventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the rece ption of the mobile two-way radio.

Hybrid system features
The illustration is an example for explanation and may differ from the actual item.
Gasoline engine
Electric motor (traction motor)
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 driving conditions, improving fuel effi-
ciency and reducing exhaust emissions.

ES300h_OM_OM33D45U_(U)
There is an air intake vent beside the
rear left seat for the purpose of cooling
the hybrid battery (traction battery). If
the vent becomes 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 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 your
Lexus dealer.
A message is automatically displayed wh en 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.
