RX450h_U_OM0E013U Please note that this manual applies to all models and explains all equipment, including
options. Therefore, you may find some expl anations for equipment not installed on your
vehicle.
All specifications provided in this manual are current at the time of printing. However,
because of the Lexus policy of continual pr oduct improvement, we reserve the right to
make changes at any time without notice.
Depending on specifications, the vehicle show n in the illustrations may differ from your

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 know that Toyota does not warrant these prod-
ucts and is not responsible for their perfor mance, repair, or replacement, or for any
damage they may cause to, or adverse effect they may have on, your Lexus vehicle.
This vehicle should not be modified with non-genuine Lexus products. Modification with
non-genuine Lexus products could affect its performance, safety or durability, and may
even violate governmental regulations. In addition, damage or performance problems
resulting from the modification may not be covered under warranty.For your information Main Owner’s Manual

* : AWD models onlyHybrid system features Your vehicle is a hybrid vehicle. It ha s 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.

For safety and security
RX450h_U_OM0E013U The air intake/discharge vents for the
hybrid battery (traction battery) are
located under the rear seats and in lug-
gage compartment respectively. If the
air intake vents are blocked, it could
lead to a reduction in hybrid battery
(traction 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 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 your Lexus dealer. ■
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. 5 3 8 )
go off. If there is only a small amount of fu el, the hybrid system may not be able to start.
(The standard amount of fuel is about 2.9 gal. [11.0 L, 2.4 Imp.gal.], when the vehicle is on
a level surface. This value may vary when the vehicle 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 vehicl es 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 condi-
tions.
WA R N I N G ■
High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt system. DC and
AC high voltage is very dangerous and can cause severe burns and electric shock that
may result in death or serious injury. ●
Never touch, disassemble, remove or replace the high voltage parts, cables or their
connectors. ●
The hybrid system will become hot after star ting as the system uses high voltage. Be
careful of both the high voltage and the hi gh temperature, and always obey the warn-
ing labels attached to the vehicle. ●
Never try to open the service plug access
hole located under the rear seat. The service
plug is used only when the vehicle is serviced
and is subject to high voltage.

Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:●
Pull your vehicle off the road, shift the shift lever to P, apply the parking brake, and
turn the hybrid system off. ●
Do not touch the high voltage parts, cables and 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 el ectric fires. Using even a small amount of
water may be dangerous. ●
If your vehicle needs to be towed, do so with front wheels (2WD models) or four
wheels (AWD models) raised. If the wheels connected to the electric motor (traction
motor) are on the ground when towing, the motor may continue to generate electric-
ity. This may cause a fire. (  P. 5 3 0 )●
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.
